Factory reset Pixel 2 XL? - Google Pixel 2 XL Questions & Answers

I just bought a used Pixel 2 XL and it is really in great shape. It came with Android 11 installed and I'm not so sure I like it. If I do a factory reset will it go back to the Android version that was installed new, think 8 or 9? Or will it just wipe things and come back with Android 11? I'm somewhat confused on what the term factory reset implies. Thanks....

A factory reset completely wipes the data partition of the device, resulting in a device with no apps when you reboot. The phone retains the version of Android it currently has. So long as yours is NOT a Verizon unit you can use a factory image from Google and fastboot commands to install an older version of Android. If you have a Verizon device you're SOL.

OK thank you for clearing that up for me. Mine is the Google version so I will have that option to install older versions....I will need to do some research here for instructions. I believe it is unlocked already so that helps the process....

How to go back to Nougat after Factory Reset?

Hello Everybody
I have really done a stupid thing to my Nexus 5X today.
I was planning to sell it and so created a dummy google account was playing with Android O in it.
I factory reset the device without realizing that it would not revert the OS version to Nougot.
The Android O is not going away even after doing Factory reset and factory data reset from Recovery.
How should i revert back to Nougat ?
I just signed as a proper Google user and opted-out from the Beta.

Got it once.. I swear. Second install, bootloop.

Hey all -
I have a Alldocube M5S. Back in January, I was able to get an A-Only ROM (8.0) installed without issue. Whohoo.
Since then, I had to reset the tablet to factory defaults. Reinstalled factory image.
Now, have been trying to get back to running a custom ROM, and seem to have hit a wall. I've tried a handful of 9.0 and 8.0/8.1 ROMs, that end in the same result: Bootloop.
Have tried doing a full wipe, factory reset, and formatting System beforehand, no difference.
Unfortunately, my debugging (and flashing) tools are limited, as the TWRP for the M5 does not seem to work on the M5S. (Which is NOT odd, due to the filesystem differences.)
Anything I'm forgetting? Without TWRP, I (don't think?) I can flash Magisk to the system using fastboot.
Thoughts're welcome!
Welp, may be a non-issue. May have toasted something while flashing the last A-Only image.
Now, I cannot even reflash the OEM's image. The flash-tool can't seem to write the data to the tablet. So, possible I bricked it. (Hey, i **couldn't** be proud, but after having been on XDA with my FIRST android phone - the FIRST Galaxy - this could be the first hard-bricked device ever!)

Android 10 - Factory reset needed?

Hello, everyone!
I just installed Android 10 onto my Pixel 3 XL a couple of hours ago and I've noticed battery drain and some lag. Is a factory reset suggested at this point, since I flashed a new Android version?
Edit:
I had animations removed under "Accessibility" and I toggled it back on, then I turned Dev. Options on and switched animations to .5x and the problem seems to have went away. I'll have to update you all on battery life later. Still, the question remains... Is a reset suggested?
I just also did the ota update and now my pixel 3xl is stuck on a Google splash screen. Did I just somehow brick my phone?

Were you on the latest beta before the update? My update file was only 5.5mb. Went pretty quickly.
is it worth factory resetting device with this latest update?

No, if you used the ota through phone, google would of already done maintenance before the install, ie, removed incompatible apps settings and features.
Has anyone flashed the factory image? If so what one did you use. I can't flash the the 10 factory image. The only was I can get it is to flash the Pie factory image, and then take the OTA. Not sure why I get an error every time I try to flash 10.

This happened to me too. After about five bootloops I finally got it to boot, but it booted back to B6, and the update said it couldn't install. I tried again, and all went well the second time.

Ive tried the update 3 times now and every time it has been stuck at the boot. I would have to turn off and try to restart around 3-5 times for it to go back to Android Pie. So still unable to update to Android 10.
Ill try it one more time later and see if maybe they changed the update a bit

I don't know if this had anything to do with it but I disabled my ad blocker and I cleared all recent apps and then when I tried it the second time it worked so maybe make sure everything is clear and you have no ad blocker enabled.
For small updates like monthly security patches or version increases of 0.1 or 0.0.1 I usually don't worry about doing a clean install since the changes are usually pretty minimal. For large updates I like to do a clean install just for piece of mind that all the crap that built up on my phone over the past year is gone, to eliminate the general issues that pop up with dirty installs, and having a squeaky clean fresh install just feels nice once in a while.

I updated 9->10 like I normally do each month by dirty flashing the full image (not full OTA) so I would say you do not need to do a factory reset. I did not previously install any of the betas. Although the install took longer and was different (fastbootd) it completed and booted to system the first time. It may just be time for a fresh install, meaning leave the wipe flag in the flash-all script and let it erase your user data.

I was doing a complete wipe.
(Update) I finally got it to do a full factory image flash with a complete wipe. The only thing I changed was, I switched from Slot B to Slot A. Not sure if that was even the issue, but It worked, and now My Pixel 3XL is running really well. No issues that are being reported.

i didnt install any 3rd party ad-blocker apps on the phone before... if there is any, it would be google's out of box one... i doubt they have one out of the box.
Im too nervous to do this update again only for it to brick again right now

Suit yourself, but if your adb/fastboot binaries are all up to date (July 2019) and you are flashing the full image (not the OTA image), then you should have no issues at all. There are many guides on how to do this properly and the procedure is no different now than with 9. Also, there is no "change" coming to make the install smoother because there is nothing to fix. If your bootloader is unlocked this phone is virtually un-brickable.

if i do a full image, not the OTA version, does that require a factory reset?

No, but you do need an unlocked bootloader. If you are unlocked go ahead and flash the full image. Be sure to do a version check of your adb/fastboot. Sometimes you can get into trouble if you have old versions in a different location. You need to be sure you are running version 29.0.2 (July 2019). If you did not lose all your user data on past attempts, do a dirty flash (removing the -w flag from the flash-all.bat file). If you already lost your data, then just run the script as-is. GL.
Edit: If you were trying to update 9->10 using an OTA, that is probably your issue. The full image will properly reformat your file system for 10.

How can I Factory Reset while rooted without bricking

So I stupidly tried to upgrade to the Pixel 4 Launcher before the official Dec update came and even after trying to uninstall/reinstall the .apk and downgrade etc, I still can't get the launcher to be remotely usable without the error popups if I have gestures on. So I am resorting to factory resetting and just starting from scratch.
I feel extremely dumb asking this as I've been rooting/customizing my phones since the G1, but about 6 months ago I had to send in a phone for RMA and when I factory reset it, wiped the OS and the bootloader was locked, so I am making sure I don't do that this time as I'm now out of warranty.
What is the process of factory resetting when I am rooted with Magisk and have the bootloader unlocked? I don't have a custom rom, just stock Android and I do not have TWRP installed. I feel like it's as simple as just going into Settings and hitting Factory Reset in Reset Options, but I can't remember if I did that or something else when I bricked the RMA phone and want to make sure.
Again, sorry for the completely stupid question, just trying to cover the bases. Thanks in advance!

It's like you said, go to settings and factory reset. Or, go to stock recovery and do it from there :good:

Question about upgrading a rooted 3xl

I have a 3xl rooted with Android 11 on it. I've never installed Android 12 because I wasn't sure if I had to de-root the phone prior to upgrading to Android 12. Can I simply go to Settings>System>System Update>Download and Install and be good to go or do I need to return it to factory prior to upgrading to Android 12? Also, I'd like to perform a factory reset on the phone because it's never had it done on this phone and the phones beginning to glitch up. What's the best order to factory reset vs upgrading to Android 12, etc? Thanks for all help in advance.
EDIT: I just saw that I have Majisk on the phone as well. It's out of date too. So any help on what order I need to perform all of the above actions in would be very helpful. I'm guessing step 1: update Majisk, 2. Upgrade to Android 12, 3. Factory Reset?
