[TUTORIAL][ZS550KL][ZS570KL/PRO] How to change device SKU to WW [29-09-2017] - Asus ZenFone 3 Deluxe ROMs, Kernels, Recoveries, & Other Development

Disclaimer
The are two main reasons to change our SKU from TIM, CN or JP to WW. Firstly, the WW firmware is apparently getting OTA updates first. In second place, Marshmallow 6.0 Bootloader Unlock process requires 4.12.40.1698 firmware version and above, but only WW got the update (you may find this useless as 7.0 update is here, but some 6.0 users may need it). This will guide you in the process.
Warning!Always have your original firmware, recovery and boot files in case things don't go as expected
Backup all of your personal data!
PLEASE MAKE SURE you are using the respective files for your CPU (ZS570KL SD820 2.15Ghz - ZS570KL PRO SD821 2.3GHz)
PrerequisitesAdb and Fastboot installed. I recommend you to install it from HERE.
Drivers installed. Try using these or Universal ADB Drivers
Python 2.X or 3.X installed.
WW target firmware. You can download it from the ASUS official website or from AndroidFileHost mirror: ZS570KL SD820 or ZS570KL PRO SD821.
Respective firmware stock recovery. You can download it from here: ZS570KL SD820 or ZS570KL PRO SD821
sdat2simg toolkit (you can find img2simg linux binary in second post).
Guide
In this case we are going to change a ZS570KL using the UL-Z016-WW-4.12.40.1698 firmware (the version needed to unlock the bootloader in Android 6.0) and it's respective recovery.
1. Extract the sdat2simg toolkitExtract the sdat2simg_toolkit.rar and you will have this folder structure:
- sdat2simg_toolkit/|-> bin / > necessary tools
|-> input/ > input system files
|-> output/ > output system files for flashing
|-> sdat2simg.bat > tool execution2. Extract system files from firmwareOpen the firmware zip and extract system.new.dat and system.transfer.list into the input folder.
3. Run the toolNow open the sdat2simg.bat file. There must no be trouble if you have properly installed python.
The tool will first convert the system.new.dat and system.transfer.list into a raw ext4 image, then it will be converted into a sparse flashable image.
When the process has finished, check the output folder. The system.img file is what we are interested in. This is our flashable system image.
4. Flash the WW system imageNow we need to reboot into bootloader mode. Turn off the device and press Volume up + Power button. Or by using adb command:
Code:
adb reboot bootloader
Now open a terminal inside output folder and flash the system image by using the fastboot command:
Code:
fastboot flash system system.img
5. Flash the WW recovery imageThen we are going to flash the WW recovery image. Open a terminal where you placed the recovery image and flash it by using fastboot command:
Code:
fastboot flash recovery Z016-WW-4.12.40.1698_recovery.img
5.a. (Optional) Flash WW boot imageYou can optionally flash the WW boot image contained inside the firmware zip. Extract it, open a terminal next to the boot.img file and flash it by using the fastboot command:
Code:
fastboot flash boot boot.img
(Not tested)6. Factory resetReboot your device by using fastboot command:
Code:
fastboot reboot
Wait until it boots up and power it off. Then boot to recovery mode: Volume down + Power button, wait for the "No command" sign
and keep pressed power button + tap Volume up to show the recovery menu.
To factory reset the device choose the following options:
Code:
Wipe data/factory reset
Wipe cache partition
7. Reboot!Now you are all up! You can Reboot your device by choosing the Reboot device now option
and you will boot into your new WW firmware. If you changed to WW to unlock the bootloader now you are able to do it.
You can also download OTA updates for WW firmware or you can manually download it and place the firmware in the internal storage, reboot and a window will prompt asking to install the new firmware.Special thanks

[INDEX] OnePlus One
[FAQ] OnePlus One Frequently Asked Questions
Intro
This thread will serve as a location for basic how-to guides for the OnePlus One (Bacon). I'm going to start off with a couple of the more obvious ones and go from there. If anyone has any suggestions for additions please feel free to let me know.
Prerequisites:
You'll need a working adb/fastboot environment on your PC to get through some of these guides. Go here to download the Android SDK, which will give you most updated version of adb and fastboot. Scroll to the bottom of the page and find Other Download Options>SDK Tools Only, and grab the right version for your OS. While it's downloading create a folder in C:\ called SDK (C:\SDK). Once you've downloaded the zip you can extract it into your C:\SDK folder. Navigate to C:\SDK\android-sdk-windows and open SDK Manager.exe. In SDK Manager you need to install the following packages:
Tools> Android SDK Tools, Android SDK Platform-tools
Extras> Android Support Library
Once you have installed those, inside C:\SDK you should see some new folders, one of them will be called platform-tools, within that folder you should see fastboot.exe and adb.exe. I'll refer to this as your fastboot folder/directory or working folder/directory during this guide. To make sure adb is correctly installed, open a command prompt from within your fastboot folder (hold shift + right click, select open command prompt here) and issue this command:
If it returns a version number for Android Debug Bridge then you're good to go.
You'll find universal adb/fastboot drivers here, download it and follow the installer, then reboot your PC.
You can test adb by connecting your device to your PC while booted into Android (making sure that adb/usb debugging is enabled in Settings>Developer Options) with the screen unlocked and issuing this command:
It should return your device serial number, if so, adb is working.
You can test fastboot by connecting your device to your PC while booted into fastboot mode (power + volume up) and issuing this command:
It should return your device serial number, if so, fastboot is working.
By attempting any of the processes listed this thread you accept full responsibility for your actions. I will not be held responsible if your device stops working, catches on fire, or turns into a hipster and claims to have been modified before it was cool. Make sure you read a section and fully understand it before attempting it.

How To Make Sure You Can Pretty Much Always Recover From An Accidentally Wiped System
How To Backup & Restore Your EFS Partition
1. How To Unlock Your Bootloader
Power off your phone then boot into fastboot mode (power + volume up).
Connect your phone to your PC via usb cable.
Open a command prompt from within your fastboot folder (navigate to where you have fastboot.exe located on your PC, shift + right click anywhere within that folder, select open command prompt here).
Check your fastboot connection by issuing this command:
Code:
fastboot devices
It should return your device serial number, if not you need to make sure your drivers are installed correctly.
Once you've confirmed your fastboot connection issue this command:
Code:
fastboot oem unlock
The device will now go through the automated unlocking process, just let it do its thing and it'll boot up into Android.
Go back to fastboot mode and issue this command to ensure that it worked:
Code:
fastboot oem device-info
It should have a couple of lines there, both with the flag set to true.
You can now reboot your phone using this command:
Code:
fastboot reboot
It's now safe to disconnect your usb cable.
Please note: this will erase all user data from your device, it is best to do this before you really start using the device and installing apps or putting data on the internal storage.
2. How To Install A Custom Recovery On Your Device
Prerequisites: unlocked bootloader.
You first need to go into Settings/Developer Options and uncheck the "Update recovery with system updates" option (to enable Developer Options go into Settings/About Phone and click 'build number' about seven or eight times).
Download the recovery of your choice (my preferred recovery is TWRP, and we'll be using that for this guide, grab it here).
Make sure you check the md5 to verify its integrity.
Place the file in your fastboot folder (this is where fastboot.exe is located on your PC).
Put the phone in fastboot mode and connect it to your PC via usb cable.
Open a command prompt from within your fastboot folder (shift + right click, select open command prompt here), and enter the following commands:
Code:
fastboot flash recovery openrecovery-twrp-2.8.1.0-bacon.img
(The recovery filename in the command will change depending on which recovery you're flashing)
Code:
fastboot format cache
Code:
fastboot reboot
Let the device reboot, it's now safe to disconnect your usb cable.
Now you can use the advanced power menu (or the power + volume down button combo) to enter your custom recovery.
Please note, if you have taken the stock Lollipop update please read the following:
For some reason CM12S doesn't respect the on/off toggle for the "update CM recovery" option in Developer Options, it just replaces whatever custom recovery you've flashed with the CM recovery regardless of whether that option is unelected.
Flash your custom recovery again, but after flashing don't do a normal reboot. After the flash has succeeded disconnect the usb cable, then power down the phone by holding the power button down, once it's powered off use the power + volume down button combo to boot directly into recovery. This first forced reboot into recovery somehow subverts what was keeping it from staying flashed and all subsequent normal reboots into recovery will boot into the custom recovery of your choice.
3. How To Make A Nandroid Backup With TWRP Recovery
Prerequisites: unlocked bootloader, TWRP recovery.
A nandroid backup is a very important thing to have before installing any custom software on your device. It's basically a backup of your stock system that you can fall back on if anything goes wrong or if you just want your stock ROM back. You can also use the backup tool to create a backup of your favourite ROM set up exactly the way you like it. The backup you create can be easily restored using the restore tool in TWRP recovery.
All you need to do is enter TWRP recovery, select the backup option from the TWRP home screen, check the system/data/boot boxes, and swipe to backup. The process will take a few minutes.
4. How To Root Your Stock Rom
Prerequisites: unlocked bootloader, TWRP recovery.
First you need to download SuperSU.
Enter TWRP recovery via the advanced power menu (or power + volume down).
Select the install option from the TWRP home screen.
Navigate to where you have SuperSU stored on your sd card and select it.
Swipe to install.
Once you've installed SuperSU you'll have an option to wipe cache/dalvik and an option to reboot system. Wipe the cache/dalvik, hit the back button, and hit the reboot system button. That's it.
5. How To Install A ROM with TWRP Recovery
Prerequisites: unlocked bootloader, TWRP recovery.
Installing a ROM is a pretty straight forward and easy process. Before you install anything you should make a nandroid backup (instructions above).
Download a ROM and appropriate Gapps package and place on your device.
Boot into your custom recovery.
Perform a full wipe.Select the wipe option from the TWRP home screen.
Select advanced wipe.
Check the system, data, cache, and dalvik cache options.
Swipe to wipe.
Install the ROM.Select the install option from the TWRP home screen.
Navigate to where you have the ROM zip stored on your sd card and select it.
Swipe to install.Most ROMs will run an installer script at this point but some ROMs have what is called an Aroma Installer which allow you to choose some install options before the script runs.
You will also need to install the appropriate gapps package directly after installing the ROM.
Once you've installed all necessary zips you'll have an option to wipe cache/dalvik and an option to reboot system. Wipe the cache/dalvik, hit the back button, and hit the reboot system button.
6. How To Install A Custom Kernel With TWRP Recovery
Prerequisites: unlocked bootloader, TWRP recovery.
A custom kernel can open up a new level of control over your device, such as overclocking/underclocking, undervolting, changing governors, changing I/O schedulers, adjusting colour calibrations, adjusting sound calibrations, and many other options.
Download a kernel that is compatible with your current ROM.
Check the md5 to verify its integrity.
Enter TWRP recovery.
Select the install option from the TWRP home screen.
Navigate to the kernel and select it.
Swipe to install.
You'll have an option to wipe cache/dalvik and an option to reboot system. Wipe the cache/dalvik, hit the back button, and hit the reboot system button.
Once your phone has booted up you can use a kernel tuning app to change governors, I/O scheduler, clock speed, and other options. Some of the popular kernel apps are Trickster Mod, No Frills, Kernel Tuner, and many more.
7. How To Flash The Stock Kernel (boot.img) With Fastboot
Prerequisites: unlocked bootloader.
If you're running a custom kernel on Cyanogen OS you'll need to flash the stock kernel back in order to take an OTA update.
Download the appropriate set of stock images from this thread. Extract the zip and grab the "boot.img" file.
Put it in your fastboot folder (where you have fastboot.exe located) on your PC.
Boot into fastboot mode (power + volume up) and connect your phone to your PC via usb cable.
Open a command prompt from within your fastboot folder (shift + right click, select open command prompt here).
Issue this fastboot command:
Code:
fastboot flash boot boot.img
It'll take a few seconds to flash the boot.img, once it's finished you can manually reboot your phone or use the following command to reboot it:
Code:
fastboot reboot
It's now safe to disconnect your usb cable.
Now you have the stock kernel back on your device.
8. How To Flash The Cyanogen OS Fastboot Images
Prerequisites: unlocked bootloader.
Please note: This procedure requires an unlocked bootloader. This procedure will factory reset your device! All user data (settings, apps, data on internal storage) will be wiped!
Download the latest stock images to your PC from here. If you don't want the latest build you can find all stock images mirrored here thanks to #Spannaa.
Reboot your device into Fastboot Mode (power + volume up) and connect your phone to your PC via usb cable.
Unzip the file you downloaded and put its contents into your fastboot folder (the same folder that you have adb.exe and fastboot.exe located in on your PC).
Open a command prompt from within your adb/fastboot folder (shift + right click, select open command prompt here).
Issue these fastboot commands:
Code:
fastboot flash modem NON-HLOS.bin
fastboot flash sbl1 sbl1.mbn
fastboot flash dbi sdi.mbn
fastboot flash aboot emmc_appsboot.mbn
fastboot flash rpm rpm.mbn
fastboot flash tz tz.mbn
fastboot flash LOGO logo.bin
fastboot flash oppostanvbk static_nvbk.bin
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash userdata userdata_64G.img
or fastboot flash userdata userdata.img if you have the 16gb model)
Please note: flashing the userdata will wipe your internal storage (your virtual sd card). It's possible to flash these images without that command if a full wipe isn't completely necessary in your situation.
Reboot your device with this command:
Code:
fastboot reboot
It's now safe to disconnect your usb cable.
9. How To Update Modem/Firmware When Switching From KitKat To Lollipop (and vice versa)
Prerequisites: unlocked bootloader.
To update from KitKat to Lollipop download the YOG4PAS1N0 firmware zip here:
cm-12.1-YOG4PAS1N0-bacon-firmwareonly-fastboot.zip
To revert from Lollipop to KitKat download the XNPH44s or XNPH05Q firmware zip here:
cm-11s-XNPH44S-bacon-firmwareonly-fastboot.zip
cm-11s-XNPH05Q-bacon-firmwareonly-fastboot.zip
Reboot your device into Fastboot Mode (power + volume up) and connect your phone to your PC via usb cable.
Unzip the file you downloaded and put its contents into your fastboot folder (the same folder that you have adb.exe and fastboot.exe located in on your PC).
Open a command prompt from within your adb/fastboot folder (shift + right click, select open command prompt here).
Issue these fastboot commands:
Code:
fastboot flash modem NON-HLOS.bin
fastboot flash sbl1 sbl1.mbn
fastboot flash dbi sdi.mbn
fastboot flash aboot emmc_appsboot.mbn
fastboot flash rpm rpm.mbn
fastboot flash tz tz.mbn
fastboot flash LOGO logo.bin
fastboot flash oppostanvbk static_nvbk.bin
Reboot your device with this command:
Code:
fastboot reboot
It is now safe to disconnect your usb cable.
10. How To Make Sure You Can Pretty Much Always Recover From An Accidentally Wiped System
Prerequisites: unlocked bootloader, TWRP recovery.
There may come a time when you accidentally wipe your OS while trying to perform a basic cache wipe in recovery. Don't laugh, it can happen to the best of us. The best way to insure yourself against being stuck in recovery is to keep a ROM zip or a TWRP/CWM backup (a nandroid backup) on your sd card at all times.
This solution seems like common sense but apparently there are quite a few people out there who don't store a ROM or backup on their phone. You might think it's easy to just mount the OTG storage and copy a ROM across to your phone from your PC (which is definitely an option), but there's always a chance that you won't be near your HDD or sd card at the time, or it won't recognise your phone properly. Basically you need to insure yourself against Murphy's law.
11. How To Backup & Restore Your EFS Partition
Prerequisites: unlocked bootloader, root.
All too often on this device I've seen folks who have a corrupted or missing EFS Partition. This results in your IMEI being lost and no cellular activity on the device at all. This can be a royal PITA to fix, and some folks haven't been able to fix it at all. You can take a precautionary measure to safeguard yourself against this by taking a couple of minutes to back up your modemst files.
Open up Terminal Emulator on your phone (if you don't have it you can download it here).
Once it's open you'll be greeted with a command line prompt, in which you can enter text commands, the first thing you need to do is enable root access by entering this line (press the enter key on your on-screen keyboard after each command to issue it):
Code:
su
If this is the first time you've used Terminal Emulator a Superuser or SuperSU popup will appear, make sure you grant root access.
Now enter these two commands:
Code:
dd if=/dev/block/mmcblk0p10 of=/sdcard/modemst1.bin bs=512
Code:
dd if=/dev/block/mmcblk0p11 of=/sdcard/modemst2.bin bs=512
The result should look like this:
This will place two files (modemst1.bin & modemst2.bin) on the root of your internal storage, make sure you copy them to your PC immediately so that you have a backup there to use if you need to restore it in future.
If by chance you end up with a corrupt EFS partition all you need to do is flash the files back to your device using fastboot.
Boot into fastboot mode (power + volume up) and connect your phone to your PC via usb cable.
Make sure the two files are in your fastboot folder on your PC.
These fastboot commands will restore the files:
Code:
fastboot flash modemst1 modemst1.bin
Code:
fastboot flash modemst2 modemst2.bin
Reboot your device:
Code:
fastboot reboot
It's now safe to disconnect your usb cable.

Nice guide!

Great guide. Short and simple, just how I like it.
Can you confirm that backups made through CW recovery are fully functional? I remember that my previous phone's kernel wasn't backing up /preload while making nandroid backups...
I don't use CWM recovery so I can't confirm that personally. I use TWRP and can confirm that backups are fully functional with that recovery.

Ive rooted my OPO, how do i perform a nandroid backup ? when i rooted i dont know if i put a custom recovery on it.. i followed this guide https://forums.oneplus.net/threads/r...6#post-3809224
You didn't install a custom recovery or unlock your bootloader if you followed that tutorial. Just unlock your bootloader, it'll wipe your data so just backup anything that's important first. Then you can flash TWRP recovery and make a nandroid backup.
Transmitted via Bacon
urgh, i was hoping i could keep all my data. Think ill give it a miss, it was only so i can install Xposed, but that should work anyway right?
If you're rooted you can just install the Xposed Framework apk and away you go. But, I'd strongly recommend you actually unlock your bootloader now, it's only gonna get harder to do the longer you wait.
Transmitted via Bacon
Come to think of it, there's a method around that'll unlock your bootloader without wiping any data, it's in the general section I think, have a look.
Transmitted via Bacon
Found it, #quinnay, here's what you want:
http://forum.xda-developers.com/onep...r-bit-t2820912
Once you've done that you can follow my instructions to install a custom recovery and make a nandroid.

ASUS Zenfone 5/6 CN, CUCC, TW to WW

After many many tries i found a way to convert my CUCC edition to WW.
This way should work for any Edition.
1.) Install ADB & USB Drivers
2.) Download recovery image (version should be smaller or equal to desired rom)
3.) Boot to fastboot mode (Power + Vol Up)
4.1) flash fastboot.img from original desired rom zip (fastboot flash fastboot fastboot.img)
4.2) flash recovery image (fastboot flash recovery xyz.img)
5.) reboot to fastboot again
6.) launch recovery from fastboot
7.) upload firmware (adb sideload xyz.zip)
8.) wipe cache
9.) reboot
Your phone should now have the desired ROM & SKU (even future OTA updates should work)

hi everyone
In this video explain the full story : flash cn/tw to ww
but i have three question
one of them that; the guy in this video when goes to adb command window and want to flash fastboot&boot ,the device is in the fastboot mode or android mode ??
Second question is that when he restart phone after flash fastboot&boot and restart ; is he restart phone to normal mode ot fastboot again ???
im not understood these parts.
And the last question is : my rom is cucc version ; so am i allow to use this rom ( cn version ) in this method or not ?
Thank u in advance..
from android mode you can simply boot to fastboot by issuing following command: "adb reboot fastboot"
or to recovery: "adb reboot recovery"
and it should not matter which version you convert to which version as long as you choose the right fastboot and recovery image (the edition you want to have as a result)
I tried this method. My fimware is ASUS_T00G_CUCC_user_1.17.40.17_20140812_9510.
At step adb sideoad : Error : "E:signature verification failed. Installation aborted. Can't open /tap/update-script.log. E:Cannot load volume /sisc!"
I used these : 1.17.40.16_ww_recovery.img and UL_ASUS_T00G_WW_1_18_40_11.zip.
Any idea please ?
have you unlocked your bootloader via official ASUS unlock tool?
I managed to update by changing the name of the WW rom into CUC. Thanks for your help.

Nice guide
awesome
I know this isn't the thread for it... but there is no forum for the ZenFone 3 Zoom.
I have US model and I've unlocked the bootloader, installed TWRP, rooted.
I want to install rom update that was just released last week. It obviously doesn't flash in TWRP. I also can't unzip it without corruption errors. Redownloaded the ROM multiple times from ASUS.
I assume to update stock rom with an unlocked Bootloader we'll need stock recovery??[COLOR="Silver"]
How did you do the rooting? No issues so far? Is there a guide somewhere you followed?
Use the bootloader unlock.
Install TWRP.
Install SuperSU zip file.
And where was that twrp install originally from? I haven't found an image for this model specifically.
Also, does this bootloader unlock still allow the pushed OS updates from ASUS? Want to make sure I can get Nougat when it comes out!
Hey guys,
I need some help. I installed the apk to unlock the bootloader and my phone was fine, but after flashing twrp and installing the zip for supersu via twrp, my phone has been stuck on the boot screen. Now it says "The dm verity is not started in enforcing mode and may not work properly" when booting up. I can get back into twrp, and I've tried wiping the dalvik/art cache, system, data, and cache, but my phone still won't boot up. It's stuck on the ASUS boot screen, and I have no idea what to do now. Any help would be greatly appreciated!

---------- Post added at 05:34 AM ---------- Previous post was at 05:33 AM ----------
No. The last update WW_V11.41.87.2 is not available for my OTA. I can download the zip though and flash. I haven't actually attempted to do this yet. I plan to flash it today. Not sure if I'll be able to do it through twrp, or if I'll have to flash back the stock recovery first.
So does this change the bands available with it? I have the WW ROM but want the additional bands the US ROM has.

Try it!This is for you if you just want to temporary boot into TWRP recovery without replacing your current installed recovery. In case you need to flash a single zip, or just becuase it's your will not to install it!
Connect your device to your computer and boot it into bootloader mode. Turn off the device and press Volume up + Power button. Or by using adb command:
Code:
adb reboot bootloader
Now open a terminal window inside the folder where the twrp recovery img file is placed and run the command:
Code:
fastboot boot <twrp img file name>
This command will NOT replace yout current recovery, it will temporary boot into TWRP recovery. This means once you are done using it, reboot your device and you will still have your current recovery untouched.
Install it!In order to install TWRP and replace your current recovery follow the next instructions.
Connect your device to your computer and boot it into bootloader mode as described in the previous step. Now open a terminal window inside the folder where the twrp recovery img file is placed and run the command:
Code:
fastboot flash recovery <twrp img file name>
Done! Enjoy your fresh installed TWRP recovery!

Just a heads up, With shaka's TWRP for the zenfone 3 zs550kl, I recieved ERROR 7 when flashing the Android 7 zip file. Flashed stock recovery and everything was fine.
Tried after that to boot from TWRP and it never booted into android, gave it a good 20mins. Figured you might want this information here.
Thanks for the development!
Hello, i tried fastboot boot <twrp img file name> but FAILED (remote: bootimage: incomplete or not signed) can you help me please?
This is not a boot.img, this is a recovery.
Google the steps to flashing twrp and you will find a guide for flashing the recovery.
Why i cant unlock bootloader ? I tried using from official website but i'm getting error failed map blabla. Please help
try download the first image on support asus and open recovery to flash and try again
So unlocked bootloader is not needed to flash twrp and then root?
TWRP can't decrypt device even with the right password...
TWRP Version 3.2.2 released!! Thanks to #shakalaca

Error loading zip and img on twrp

Hi guys. I have a problem with my ze500KL. I can install only the twrp 2.8.7.7 version. But when i try to install img or zip of roms /original firmware, the twrp fails the operation , saying " error data", "unable to mount"... i have problems with wipe too. any solution?
I can't understand what you mean. If you want to install stock rom from TWRP recovery, you have to modify updater-skript.
Why do you can install only the twrp recovery 2.8.7.7, when we have the twrp recovery 3.0.0.2
File img you can flash from fastboot mode. Commands:
fastboot flash system file.img
fastboot flash recovery file.img
fastboot flash boot file.img
or
fastboot boot file.img for example twrp recovery img or stock recovery img. This is command for once booting.
I want to return to original firmware , i download it from the site of asus. So, i booted twrp in fastboot mode (i tried different version of twrp, but the only that starts is the 2.8.7.7 version) using adb.
Now i am in recovery with twrp 2.8.7.7. I can push using .zip files or img files on internal storage.
But i have different problems with this recovery:
IF i use wipe function: error opening sys, could not mount, enabe to mount, ... (failed)
If i install rom or firmware with zip files: error unable to mount, unable to find partition for path.... (failed)
Adb sideload goes failed too.
What should i do???
I think that the problem is in the internal partition... I have to install using a min usb ext storage? or what????? thanks
Easiest way to fix your phone is flash stock rom from stock recovery. Stock rom put to sd card. Reboot to stock recovery and choose flash rom from sd card. New version number system must be the same or higher than installed in the phone.
Do you want to return to the lower version of Android.

Do you want to flash stock rom from twrp recovery.

Stock recovery doesn't work man. The only recovery that works is the twrp 2.8.7.7. But it has problems.
Do you have Lollipop or Marshmallow and what is your version number.
For Marshmallow you need to this working twrp recovery.

For Lollipop you need to this working twrp recovery.

If you haven't installed stock recovery, it's not no problem. You can it flash from fastboot mode.
i had mawshmallow. i tried but failed...
How did you flash the file twrp.img.
OK guys I've solved the problem. I moved in this way:
1) Volume up + power to go in fastboot mode
2) after installing adb and the other drivers, i've insered these commands:
fastboot erase cache
fastboot erase userdata
fastboot erase system
3) after downloading twrp version 3.0.0 (for the zenfone 2 laser), I load it using the command "fastboot boot (name file twrp).zip"
4) the recovery starts automatically. Now i downloaded the file "back2stock.zip" and the original firmware (WW, worldwide) form the official site of the Asus
5) this passage is the most important:using 7zip I've extracted the file zip of the firmware and the backtostock, then i created a new file using 7zip : in this new zip i've loaded the files inside back2stock and the files file_contentexts, system.new.dat, system.patch.dat, boot.img e system.trasfer.list inside the zip of the official firmware
6) I've loaded this new file on the phone using the command "adb push (new file name).zip /"
7) at last i have installed this file on the phone ENJOY it
