Unfortunately you cannot There is a Pie downgrade file on here floating around you will have to use.

hey guys, is there any way i can restore all apps and data after upgrading from latest stable oxygen to android p beta (and a wipe that follows the upgrade)? not sure if oneplus switch backup function does the job or what about TWRP backup? my device is not rooted btw.
thanks!
DId you take a backup in TWRP before flashing to P?
If you did you may be able to boot into TWRP and restore just Data and reboot, you should still be on P but have all your apps and data available.
There was no wipe the last time I upgraded from stock to p beta. It upgraded it just fine.
Hi,
With my playing around with AOSP on the 3a, I've found TWRP to be reasonably reliable to restoring me to a functional phone after I blew something up. What I haven't tested is rolling back from Android 10 builds to a Android 9 backup via TWRP.
I'm wanting to try out Android 10 AOSP builds using the RattlesnakeOS AWS Stack scripts but I don't actually know if my Pie backups taken with TWRP will restore correctly. Especially since the partition layout is changed with Android 10.
My intuition tells me I can do this to roll back to an Android 9 TWRP backup.
1. Flash an Android 9 factory image from Google via fastboot. This will allow a downgrade as it will repartition the phone back to the Pie partitioning layout
2. Boot TWRP and restore my Android 9 backup. System, Data.
3. reboot.
Does this sound reasonable? Basically I have a free weekend and I'm very bored and feel like blowing up my phone all day
Hello everyone,
I have a question about the update process of OOS while having Magisk installed as described in this thread: https://forum.xda-developers.com/oneplus-8/how-to/guide-how-to-root-oneplus-8-twrp-t4084849
I've heard from a friend which has a OP8 Pro and a few users on the internet that after a software update the fingerprint no longer functions when you have Magisk (Canary) installed while doing the update and that people need a backup of their persist partition to restore this functionality.
Now I want to make sure I have a backup of this and any other essential partition just in case something does go wrong because currently I'm on OOS 10.5.4 and a update for OOS 10.5.6 is ready for me in the OOS System Updater.
So which partitions should I back up and what app, tool or something else should I be using to back these up?
Thanks in advance.
What I knew regrading fingerprint sensor doesn't work during using unbrick tool to restore your device to oxygen OS. There's nothing to do with root(Install Magisk). If I don't misunderstood.
Hello! I'm trying to restore EFS Backup on TWRP but nothing is changing. I tried reinstall OxygenOS but nothing happening. Backup android version and twrp version is different with mine btw. What should i do? Thanks.
Hello! I've been rooting and installing custom ROMs for years but it's been a long while since I last did it, I got a oneplus 8 global (IN2015) late last year, unlocked the bootloader as soon as I got it out of the box since I knew eventually I would want to flash some stuff. but I have kept it stock this long. Running latest Oxygen 11 android 11
Since I want to start flashing some kernels or roms I wanted to ask about making a backup since I've never had a phone without sd card slot where I would usually store backups.
Can I still use titanium backup to keep all of my apps/data/photos/videos and the state they are in, store it in my pc , then go about flashing a custom Rom and then bring my titanium backup back into the phone and restore everything?
since I'll be installing custom roms based on android 11 I believe it will be fine with no conflicts? or does it matter that my apps were installed in Oxygen OS?
that's what I used to do with older phones anyway. is there a way to flash a rom while having the titanium backup still in storage since most roms require full whipe when clean installing them?
Recently twrp added official support for OP8 and when I open the official app it recognizes my phone as instant noodle but when I click search for phone it says it can't connect to the server? should I flash official twrp from the app or via fastboot? which I'm also quite rusty with.
any tips for a step by step would be appreciated
Hello, I was in the same boat as you since I came to the OP 8 from a Galaxy S4. Titanium backup should work for what you want to do, as long as the custom rom is also based on A11 (disclaimer: I haven't tried it; I'm running rooted stock OOS 11 with a custom kernel). If the rom you want to install requires a data partition format, you can't keep the backups there during the flashing process. If it only needs a data wipe / factory reset, everything in the sdcard directory (also known as /data/media) should be preserved.
I'd say just flash TWRP in fastboot. Flash it to both recovery slots, and read up on how flashing works with A/B slot devices if you aren't familiar, since you'll need to know about it when flashing roms also. It's a big difference from what I was used to with older devices.
Thanks for the reply, yeah I was thinking of just going with a custom kernel since I have so much stuff going on the phone I find it really a chore to backup, but still might want to try it.
What kernel are you using and how are you liking it ?
