Hi all. Was curious what is the best way to downgrade from pie. I upgraded and don't like it. I have a twrp backup of 8.1 but when I restored it I just bootloop. I know Google makes it difficult to downgrade so was wondering if it can be done, preferably without losing data.

Did you have to wipe data? Thought you couldn't use Google's images to downgrade.

I did a full wipe, so yeah. Not sure if you can ota downgrade, plus I don't want to risk it or have any headaches. Just titanium backup and restore for me.

Yeah. Full wipe and run the flash-all.bat from the July 8.1 factory image (or whichever image matches your TWRP backup). Then you should be able to restore from your last TWRP backup without any issue. If that doesn't work, at least you can restore from TiBu if you have it, you'll just have to set the device back up and manually set all your system settings.

I don't think it's as much an XDA problem as it is that this subforum doesn't get a whole lot of action. All around activity for the Pixel2 is pretty quiet. Its hard to say exactly why, but I'd wager it's probably due to the overall satisfaction with the device and the stock OS as is. That said, XDA activity as a whole definitely isn't quite what it used to be.

Hi all,
want to know how to updated rooted android phone as OTA doesn't work for root. Have been told KIES will brick the phone.
tnx
If you want the official update, just flash the new system image, and then re-root.
But do I have to unroot first and is there any risk of brick?
Not a huge risk of getting bricked, this is a pretty simple process. But just in case, you should back up all of your stuff. You do not have to un-root before re-flashing, just delete and clear everything from fastboot. If you are on a Nexus, this article should help you: http://www.digitaltrends.com/mobile/how-to-install-android-factory-image/ Good luck.
Its Cannot Update After Root....
Cause Server will Detect Your Device Did a Unathourized Modify...

PS by just "delete and clear everything from fastboot" do you mean data and cache wipe from download mode?
Just take a backup of your present system
If you are new to rooting most probably you will make some mistakes so having a back up always helps and always knowing where the backup is stored
Just be careful and flash the new image after backing up

PS what options should I tick in ODIN when flashing 6.0.1 or 5.1.1 over 5.0.1? As I am getting different answers and it's a bit confusing.
I have no idea...
Sent from my Moto E using Tapatalk
So, I falshed the 6.0.1 on my note 4, but now there is a new built from 25th May. As I already rooted the phone, I would like to know whether I should unroot first, or I can just straight flash that new built with ODIN. If I do flash straight away, will I loose root or any data?
WOW. so many replies.
Hey guys. I think I, pretty familiar with what I need to do, but I haven't done it before. Currently I'm on the FEBRUARY security update (7.1.1) and have root. I am hoping to upgrade to 7.1.2 without losing any of my personal data and apps. I am weary to try flash fire, so could someone more experienced help me out?
I know I need to download the full OTA image and flash it and remove some -W flag, but I don't want to brick my device or lose my data, so I'll let you guys steer me. Thanks in advance, by the way!
P.S. I never fully installed TWRP.
Every time, I download the full factory image and flash via flash fire.
Everything is good, except losing twrp, but i do not mind. root still available

I have tried to stay away from flash fire because I know a couple buddies who soft-bricked by using it.

Alright thanks dude. Which version of 7.1.2 should I get. I know some are made for different carriers but I'm in the U.S. and have a Google Store Pixel (non-XL) and using it on Verizon prepaid. I assume that should grab N2G47E, but I just want to be sure.
The other 7.1.2 is for Dutch Telecom? I just don't want to flash the wrong one on lol.

No problem at all. Second to the last post in the same thread I linked you to before. It all still works fine on 7.1.2. Did all of this myself yesterday afternoon.
Sideload did not work, used flash-all.bat deleted out the -w. When the device booted up it automatically wiped everything anyways
Download the OTA, Flash it from TWRP, reflash twrp and reboot

Did you save the file after you edited it? Take a look at the flashall you used and see if the -w is still in there. Willing to bet it is. I've done this for every update since November. Never had a problem. The only thing I can think of that would cause your data to get wiped is that you didn't save the changes after you edited it.

yeah saved it. There was only one section that had the w- and it was right before the update image. I can try it again at some point later on but that's what I did. I tried to sideload adb the OTA first which does not wipe data but kept getting an error saying device not found and emulator.

Your instructions worked perfectly for me. I'm nor sure what setup the other guy had, but I did make sure I removed the -w like 20 times.

You need to save any photos and files on your phone, either on the cloud or your PC. With a major OS update like this, if you don't do a factory reset you will have problems. Battery drain, apps force closing, spontaneous reboots.
If you don't want to do a factory reset, then you're better off not upgrading. It's not worth the misery.
FWIW: I've not seen an Oreo beta that can be flashed via Odin. Are you sure it isn't the one in the General section that you install via ADB sideload?

I am currently rocking the Open Beta 2, I wanted to manually update to the latest stable version of Android Q (not open beta), but I get a message saying that I'll lose all my files (factory reset) which I don't want.
will there be stable OTA for open beta users... Should I wait? Or eventually I'll have to flash it manually and lose my data? :crying:
Thanks!

When the beta was out I remember people saying in the thread that OTA to stable would be available but I have since learnt that OnePlus never push OTA to stable for beta testers, if it is true it is a shame and a strange decision because less people would testa beta and find errors.
Looking at the help text for oxygen updater it seems like they also mention factory reset
It's always been the case that if you test betas you have to wipe for stable installation. Nothing new. That's just the way it goes

Everyone is not keen or have the need to unlock the bootloader and flash a custom recovery... Doing that now would anyway still mean that you have to wipe the phone.

From the looks of your situation, no, you can't fix your phone without losing data.

Yeah, sure. But this is a different case. This is a major update, not to mention it's a beta. Anyway, you could try wiping your cache partition first. You can do that on recovery mode. This won't wipe your data.
If it doesn't work, I don't know any other solution to fix your device while keeping data. If you're ready to let go of your data, the easiest way to surely recover is using MSM Download Tool.
EDIT: I just remembered there's no cache partition anymore. You'll need to wipe cache AND data. I can't check the stock recovery because I'm on TWRP myself.

My wouldn't boot after updating a magisk module, I salvaged it by flashing stock boot img again, it's not the same situation but worth a shot.

As a last resort before wiping try changing the active partition from fastboot:
fastboot --set-active=a
fastboot --set-active=b
Good luck.

your chances of keeping your data without a backup recovering from a bootloop is very slim. the simplest solution would be to wipe your data and cache from the stock recovery. If that doesn't work, you might have to go towards using the msm download tool to unbrick your oneplus 6.
