Hi all I'm having hard time time in finding a way to restore back to stock.
I'm on OOS 5.1.8 with twrp official and Magisk
Can you please share how to format the phone completely and again install 5.1.8 or 5.1.6 oos?
Reason for this is poor battery life after last few iteration of updates. Need to see whether it fixes it.

Make sure you have your full ROM zip files on your phone. Disable secure lock screen in OS. Boot TWRP, backup data only. Wipe everything (data is optional) install ROM zip file, reflash TWRP zip, reboot. You can always restore data at any time after wiping it and it will be as you have it set up to your preferences. There aren't major differences in OOS versions so erroes shouldn't occur with data on any of them. If you want root, you can boot back into recovery and install magisk.

can someone confirm this procedure is valid which mikex has confirmed? Since on this post https://forum.xda-developers.com/oneplus-6/help/help-flashing-oos-5-1-8-zip-via-twrp-t3814614 he did the same and got BootLoop

Just use this, let OTA update run and you're done. There's no easier solution.

You shouldn't get a bootloop if you flash stock firmware via TWRP unless the file itself is messed up. Bootloop can occur if you flash magisk right away, I think. You have to reboot recovery before flashing magisk.
I have tried a couple of roms and I always end up bricking my phone when I try to move from one of the flashed roms back to OOS and have to resort to using msmtool and start over with 5.1.5.
Can someone please guide and advise on the best practices for flashing roms and then going back to stock. Thanks
Depends what roms you are trying to go from.. And what security patch the first rom is on.
When going back from let's say September to July you will have to format phone only to install oos again.
How have you done the procedure when you brick it?

Thanks for your kind reply, I format system, data & dalvik partitions & then install OOS and always end up with a bricked phone.
I believe format
Install twrp
Reboot to twrp
Install oos, install twrp
Reboot to twrp
Install oos, install twrp
Reboot to twrp
Minstall magisk
So you get it on both partitions

you mean encrypted? should be fixed with a format, or rather it's the only way afaik..
proper way is to take backups and keep off of phone, so that if you're going down android security patches(not sure what else, if anything triggers it), you'll have needed data on hand
When you switch from one rom to other Format data it's the way.
When you want to go back from Android 9 to android 8 you need to install a rollback rom.
Oos allways encripts youre phone and you will go back to Oos recovery.
Hello, I am a noob and i would like to know how to revert back to stock oos stable from open beta without pc. I have installed twrp but i want to install stock recovery too. Thanks.

If you have TWRP, flash the OOS Stable Zip + TWRP, reboot the recovery, and there flash only OOS.
You will have OOS Stable in both slots, and the second flash will replace the recovery with the one from OnePlus
You may have to Format Data at the middle of the operation (When you reboot the recovery before the second flash). If that's the case, you won't be able to do the second flash, because the OOS zip will be erased !

Not necessarily. If you just flash OOS Stable, and Format the Data after, you will have a perfectly working device, with OOS Stable and OnePlus stock recovery. The storage will just be totally empty (So no Zips left to flash anything else like TWRP or Magisk), but the phone will work, just like when you first bought it ! If you don't want to flash anything more than OOS, then yes just flash the ROM, Format Data, and reboot
A PC would be useful if you want to flash OOS a second time to fill the second slot. But even then, you could do without one :
- Flash OOS
- Format the Data
- Reboot, setup the phone, install apps, ect
- Download the OOS Stable zip that has been erased when you formatted from Chrome on your phone
- Do a "Local upgrade" from the Updater in the settings, and flash 9.0.5 again
- Now you have a totally stock OOS Stable phone, with 9.0.5 on A and B System slots, clean as a baby !
I did this exact procedure myself this moning after being stupid and messing with the encryption, and not having an USB cable near me to use a PC

Bro last question, the local update metod works too?
Just install the rollback zip through the local update and reboot.
Nothing else is required
It'll wipe out your data though.
Hi fellas,
I'm running OOS 9.5.7 GM21AA and rooted using Magisk.
I got a notification for the 9.5.8 system update. I would like to upgrade the OS but would still like to keep root (and don't wanna restore my phone). However, I have still backed up to Google Drive, and also using the OnePlus Switch app and copied the back up to my PC.
My question is, what's the best way to go about updating the system without having it touch my data?
I know the system update will unroot the phone automatically, which I'm guessing is going to delete all my data (because my device is rooted). So is there a way I can UNROOT separately so I don't lose my files and data, --> and then after that do the system update?
Can I download 9.5.8 from the web manually and install via TWRP for example, thus not messing with root and not losing data?
Thanks for your help in advance!

Thanks for the quick reply.
Just to make sure, following those steps I shouldn't lose my data, correct?

Correct. I didn't lose data when I did it awhile ago but I would still make a Google back up just in case of any errors

Awesome, thanks again! :good:
See here, as the exact question has already been asked and answered: https://forum.xda-developers.com/oneplus-7-pro/help/how-properly-update-t3942735
I know you did already got an answer, but there is additional info on the other thread.
In particular, I would reiterate would I posted about data retention when updating:
Yes, it should retain your data. I just updated to 9.5.8 a few days ago, and it kept my data intact (by the process of updating in settings, don't reboot, in Magisk Manager install TWRP installer in inactive slot, etc.).
But what I always say when attempting a "dirty flash" (flashing the ROM, but retaining data) is: hope for the best, prepare for the worst. Backup anything that is important to you before any big update, just in case. What should happen, and what actually happens, are not always the same thing!
@omar0aziz, no, losing root does NOT mean you lose your data. (This is not to be confused with locking or unblocking the bootloader, which will inevitably lose your data.) If you lose root, simply flash Magisk again.
The best way to update? I recommend taking full manual control of the update process. Use TWRP to update your ROM (that includes stock OOS) when you want to, and when you need to fix stuff.
- Flash ROM
If you are on slot A and flash a ROM, it goes to slot B.
- Flash TWRP installer zip
Keeps TWRP on both slots, patches boot.img
- Reboot to TWRP, not system
- Flash ROM again
This installs the ROM to the other slot, so now both slots are updated
- Flash TWRP installer zip again
Keeps TWRP on both slots, patches boot.img
- Flash Magisk
Patches the TWRP-patched ROM, allowing it to boot.
- Wipe dalvik
You can wipe data and dalvik instead for a clean flash
- Now reboot to system
(Keep in mind that in most custom ROMs, you will need to do an initial setup of the ROM, then reboot to recovery and flash Magisk again to get root.)
Consider flashing BOTH slots (A and B) whenever you update OOS, for two reasons. First, you don't have to keep track of which slot has which version of OOS should you flash a custom ROM or kernel with a specific version of OOS required as a base. The second reason is more compelling: the way the data partition changes encryption every update has nearly obviated the reason for A/B slots, in that if newly updated B changes data encryption upon boot and then something happens, you cannot revert to A because A can't read the new data encryption. So the solution is to update both A and B at the same time so both slots use the same encryption and can both access the data partition.
Or like me, run the device decrypted (i. e. without forced encryption).
Good luck!
Hi,
after installing and uninstalling some Magisk modules, my device (OP6, OOS, blu spark TWRP, Magisk) randomly froze and after restarting, it keeps booting forever. I can still get into TWRP, so I tried a few things to fix this like:
Uninstalling and reinstalling Magisk
Flashing OOS, TWRP and Magisk again
Flashing just OOS,
but nothing seems to help. Is there a proper way of fixing this without wiping my data partition?
If there is not, how do I save as much of my data (like system settings, app data etc.) as possible from TWRP so I can restore it later?
Thanks for your help

Have you tried flashing only the boot img?

I think you might have to wipe if you can't get your phone to boot after dirty flashing ROM. I would try flashing your boot. Img first in case it's magisk related problem. What ROM are you on?

You can backup data in twrp but that might be the reason you can't boot. Google backup should of backed up most things. At this point you should be more concerned about getting your phone to boot.
