How to get Verizon pixel xl back to stock so I can install TWRP.

[defens23]

Noob again. So I am rooted and I'm currently on build NDE63X on my Verizon 128 gb XL. If i understood the instructions correctly, I have to go back to stock before I can put TWRP on the phone. I know I get the factory images here.

https://developers.google.com/android/images

Do I get the NDE63P image for the phone since that was what was on the phone before I sideloaded the OTA for my current version which is NDE63X or do I just need to download the full image for NDE63X?

Can someone also list the steps needed to accomplish getting phone back to stock? I read Google's instructions and I was a little confused. I understand that I will lose root but should be able to root after installing TWRP since it looks like Chainfire updated the root method for those using TWRP.

Thanks.

It's easy bro. For starters, grab the factory image for the X build. No need to go back to P.

Next, extract the zip. Depending on which OS your computer runs, you'll be running one of the flash-all scripts. the one with the ".bat" extension is for Windows and the one ending with the ".sh" extension is for macOS and Linux. If you don't want it to wipe your device, before running one of those two files I just mentioned, your gonna wanna edit the script file using an application like Notepad++ (on Windows) or Text Wrangler (on macOS.) What you want to do in the script file is remove the wipe command. To do so, delete the following piece from the script: (it's towards the bottom.)

-w

Save the changes.

Next, copy everything from the factory image folder to where you have adb/fastboot stored. (I suppose you could copy your adb/fastboot files to this folder if you wanted to.)

Assuming that your device is plugged in and USB debugging is enabled, start command prompt (or Terminal.) and type the following commands:

adb devices (it should return with your devices serial number and say online, if not check your device for a prompt asking to allow or deny.)
adb reboot bootloader
fastboot devices
flash-all.bat (or flash-all.sh)

That should do it. ?

My command prompt hangs when I try to execute the .bat file
Says "Waiting for any device"
And yes the device is listed when I do ADB devices
Any ideas?
THANKS!!

if you are executing the commands, you are in fastboot, not adb.

try fastboot devices

if it doesnt return anything, your computer is not seeing the device.

you will need the computer to see the device in fastboot before you can proceed.

OK so ADB Devices finds my cellphone but fastboot devices yields nothing.

Any ideas?

first thing to try is to go into fastboot, then unplug the cable, and then plug it back in.

if it is still not recognized, then its either an outdated adb/fastboot issue, or a driver issue (if you are using windows, if not there may be other possibilities).

When it finds your phone does it say unauthorized or authorized?

 

[chipslate]

See attached. That is what I get every time. I have had the same thing happen on 2 different Windows 10 boxes. Makes me think it is something on the phone?

What happens now when you attempt the next command?

Edit: So after running adb devices, you should be running adb reboot bootloader command next I believe.

 

[chipslate]

Yes, ADB reboot bootloader brings up the fastboot screen on the Pixel XL with the green android thingy.

Also, I have the phone in MTP File Transfer mode and USB Debugging enabled.

You should now use the flash-all command but this is going wipe all of your data.

 

[chipslate]

I am fine wiping all my data but running flash-all.bat hangs the CMD window saying "Waiting for any device"

That's my problem.

Post a picture of when you have that and of your phone at the time you type flash all if you can. Also hit the reply button on my post and itll give my notifications when you reply.

It finally worked!!! Thanks again for your help and going back and forth. I finally installed Android Studio and it inserted the ADB drivers at the top of Device manager. Worked like a charm then. Finally, Android 7.1.1 and unlocked bootloader... Bring it on, world!

 

[magestic1995]

Congrats! I've only used Android Studio for all this stuff since Im a developer. Congrats on getting it all figured out!
