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.

Thanks I'll give it a shot
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.
I have a rooted OnePlus 7 Pro running OOS 10.0.1 rooted with Magisk but everything is very glitchy and I probably did something wrong. WiFi doesn’t work, boot slot b is non functional, and I’m just done with root. I need help. How do I return COMPLETELY TO STOCK, and lock the bootloader and unroot without tripping safety net or bricking? OnePlus support said they could do nothing. Every post on XDA advises to never relock, but I don’t know what else to do. I’m new to this stuff. Thank you for your time.

If you want to go completely stock locked, Use MSM tool it will put full stock and lock the bootloader for you. Beware will wipe all your data backup all your personal data first

If you manually flashed a patched boot.img, you probably just flashed in incompatible one (broken WiFi is a dead giveaway for this issue). Better to just boot TWRP, flash Magisk and let Magisk patch the boot.img.

Everything went through and I have my phone working again. But I have one last question... My phone was the GM1915 model and that's what's printed on the box. But now in settings the model number is listed as GM1917. What kind of issues, if any, will this cause? Or am I good to go?

Hi,
I have big problem, I was trying to update my OP6 to Android 10 beta and phone can't turn on, only spin round on logo and can't go further. I'm on stock, no root. Please advise what can I do ? I can't lost my data.
How did you update? Share the instructions?

You didn't backup your data like everyone advised including OnePlus themselves?
From the looks of your situation, no, you can't fix your phone without losing data.

I haven't got any of case like this that update by OTA can do bootloop on normal stock. That's strange. What is your advise in that case ?

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.
https://forum.xda-developers.com/oneplus-6/how-to/patched-boot-image-magisk-16-7-beta-t3818853
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. Here's the link to the thread with the msm download tool: https://forum.xda-developers.com/oneplus-6/how-to/op6-collection-unbrick-tools-t3914109

Are you on beta 5 because this is only for beta 5 if you go ahead and install it on any other versions then it was on your own risk.
Also, provide original boot.img if possible.

As it is clearly mentioned for O2 beta 5 if you flash it on any another version i am pretty sure it wont work. Send me original boot.img on telegram or contact me for any problems.

As you messaged me earlier you did flash the boot.img on 10.0.2.0 without checking your version and thought it would work. And also you rated my thread 1 because your wanted "attention".
Please do not argue on this thread if you try to install it for any other version than mentioned.

Finally worked for you. I will soon post the stable patch after I get its boot.img
Thread locked due to OP's request.
Okay... I've been searching all over the net for this problem and I keep getting posts that skirt the issue. At least, that's what it seems. So I will begin and you can decide... and thanks for whatever info you can throw my way.
Brand new OnePlus 8T. I want to root it. Duh. So, Got the Tiny ADB and Fastboot package and all the rest, but the issue is with unlocking the bootloader. Other problems may appear later, but this is the issue now.
So, connect phone to PC (Windows 8.1) and the only way that ABD recognizes my phone is when the USB prefs are set to 'No Data Transfer". Yes, I have installed the proper drivers from the phone. So, when the 'No Data Transfer' is selected, ADB recognizes the phone and will issue the command, ABD Reboot Bootloader and the phone reboots to the bootloader. Nice! Unfortunately, it appears that once the phone has booted to the bootloader, it has changed the USB Prefs and now ADB and fastboot do not see the phone. Obviously this sucks. And here is the problem. As far as I know, I have ticked off on all the proper settings. USB Debugging, etc. No joy!
I found a post elsewhere that showed how to set the default USB mode and that didn't work either. My experience has been that ADB used to see the phone under the 'File Transfer' and PTP options before, but it doesn't now. I can't explain this.
So, pretty frustrated. This shouldn't be so bloody difficult. It's only a couple of commands and I have done this with other phones in the past so it's not like I have no previous experience. But I have already wasted way too much time here this go around. Anyone have an answer? I'll be your best friend!!
Thanks all..

How to Install Official TWRP Recovery on OnePlus 8 and OnePlus 8T and Root it
OnePlus 8 and OnePlus 8T (codename: instantnoodle/kebab) was launched in the year April and October 2020 with Android 10 and 11 respectively. Recently
www.getdroidtips.com
to root my 8T, but it appears that this fellow was missing some info? I take it ya can't just flash twrp to recovery like usual. The picture is slowly coming together.. much more complex than the last few times I have rooted phones.
So I assume that flashing twrp writes over the stock recovery.. and that leads to this crashdump mode popping up. To fix this, I will need the stock recovery.img and flash that back into place? Feel free to chime in and thanks in advance!

Flashing TWRP doesn't cause CrashDumps. They happen when you try to boot the system and something's not right.
You could try changing slots and then rebooting. That sometimes works (depending on what else you've done). You can do this in either TWRP or bootloader.
PS: if you use the reply button, then I'll be advised that you've posted a reply. Otherwise you'll have to wait until the next time I look to see if there's new posts in a thread.

Alrighty! Changing the slots did bring the phone back and it is now booting properly. But if I try to boot into recovery, it fails and goes to crashdump. Any ideas? Bad twrp image??

but since Android 11, the data decryption is no longer the same.
just the 30 second twrp boot, I don't really like it, so restored a system with something like that ... lol

If they could fix the interminable start up time for TWRP that would be brilliant. But I believe the problem is with a file system check rather than the actual decryption which is quite fast.
Sorry, croquettes and mash aren't in my menu. But empanadas - absolutely!

Actually a trick you can use is in twrp if you have the magisk APK change the ext to zip and install in twrp it patches the boot img for you in right slot so you don't have to pull img from phone
