Thanks for the answer.
Which recovery have you used? Stock or twrp?
If you run Oreo, can you tell me which partition can be mounted?
On pie I have 2 system partition: system and system_root and I have lots of problem to install gapps.

I get this error message when I try to install Pico gapps on Android 9:
INSTALLATION FAILURE: Your device does not have sufficient space available in
the system partition to install this GApps package as currently configured.
You will need to switch to a smaller GApps package or use gapps-config to
reduce the installed size.

You may have to reflash system partition or just flash firmware though local update in settings and try again if that doesn't work try flashing update though twrp

You can use this recovery, when you're on Oreo: https://forum.xda-developers.com/mate-9/development/preliminary-twrp-3-1-1-0-mate-9-emui-8-t3687622
Then this SuperSU: https://androidfilehost.com/?fid=962021903579485056
There's no Magisk yet.

I've yet to try decrypting oreo, but you should be able to modify the updater-script in both public and HW zips, and remove the command mountcrypt and the last that should normally install update.app.
So unzip, edit, zip. It should work if it's just the Huawei commands that are making it reboot.

Not possible with twrp

It should be possible. I don't think SuperSU changes/removes everything it needs to though, as we now seem to have 3 different fstab rather than 1. It should be possible to modify the AVB script to remove fileencryptioninline.

Much has changed since I posted that
Use this TWRP: https://mega.nz/#!4DYngAxL!OJEgQ4a4cSTypHgRBbMQbok2BRDuVHSDXNktAJ_PnKQ (flash to recovery_ramdisk)
With official Magisk v16 : http://tiny.cc/latestmagisk
I don't think SuperSU will get more updates tbh, and I haven't tested it lately. I do know that Magisk works on AOSP
Hello guys, first Sry for my bad English...
I have an wired idea but I don't know it's Funktion or not because of that I quest you guys and hope that anybody have experience with these.
How anybody who use magisk know, you can hide your root to apps and system too, when I hide the root to system update then he only want to download an ~300 MB update (actually installed version: 1.5.6 because the problem in 1.5.7/8 (original os and no twrp installed)). Also it is possible to update my system at these way and I have root after the update or what can happen?
Your Patrick

To keep root with an update, you need to flash the full update in TWRP, reflash TWRP, reboot recovery then reflash root. Otherwise, you will need to do the steps all over again every time you update to get root back.

Thanx
Thanks for the fast answer
Also what I have to do now is:
1. Download the actual OS
2. Change recovery with twrp
Reboot recover
3. Flash OS with twrp (first full clean?)
4. Flash twrp
5. Reboot to recovery and flash magisk
Did I lose at these way my data? Or did I do here an dirty flash? When yes what data recovery tool do you recommend? Titanium?
And after these, I can update my device per OTA updates and I don't lose my root?

You can install TWRP or you can just install the OTA and then just follow steps to root again the same you did before.

At first: backup data and phone memory.
You can do local update (download from official web site oneplus https://oxygenos.oneplus.net/OnePlus6Oxygen_22_OTA_045_all_2004142201_bdd6fdc6b6b1477f.zip, v.10.3.3 or from nonofficial sites 10.3.4, copy to phone memory, main directory, go to settings and system update, make local update - and choose copied file from phone), next after update and restart, do wipe cache, restart and you will see what happend.
Try to read oneplus guide:
How to upgrade system?
Download the software build for your device on this page. Please back up your data before flashing your device.
Plug your phone into your computer and copy the downloaded .zip to your phone’s storage. If you’re using a Mac, you can install Android File Transfer Android File Transfer for this operation.
After the .zip file is copied to your phone, go to 'Settings' - 'system update', click the 'settings' icon on the top right corner, choose 'Local upgrade', find the .zip file and click on 'Install' to confirm.
The update takes about a minute (depending upon the file size), once done reboot your device to boot into the latest Oxygen OS.
Hello Guys, I need some help: I installed Resurection Remix v8.6.6 with the fw V12.0.7.0.qjgeuxm and would like to update it to V12.0.8.0!
The Rom is encrypted, however!
What steps do I have to carry out to cancel the encryption and flash the new firmware?
Many thanks in advance
greetings
H0rdak
if you only want to flash firmware 12.0.8 flash this in recovery and you don't need to do anything else, reboot to recovery just to be on the safe side, then reboot to system...
on the other side, if you want to reflash whole 12.0.8 SW base, that's another case...
THX JERYLL, you're a great help again !!!!
Okay, I mean, I transfer the FW zip file to the phone and install it via Orange Fox?! I still did not understand that with the encryption as explained in the RR thread! Can I easily flash the ZIP file?

yes either download or transfer, then flash in recovery, I did it yesterday, so its safe to do
thanks jeryll,
i have done it now and the system has displayed an error message at the vendor! Do you know whether the update was successful anyway, and where can I read which fw is now installed on the phone ?!
if you did flash only firmware part of 12.0.8 you can't see it in system as a regular update as you only updated drivers which allow to communicate between SW and HW, so when you start up OFOX, on its initial screen you can see the number of the last flashed whole MIUI ROM (for example if before flashing custom ROM you were on MIUI 12.0.6, then flashed RR 8.6.6, now updated only fw part of 12.0.8, your system will still be shown as 12.0.6...
If you are hunting this new number 12.0.8 and not pure functionality, you'll need to reflash full recovery version of MIUI 12.0.8 EU, that will reflash most of the needed components on your phone including vendor and product and then you'll see that number in OFOX. But because in the process your original custom ROM will be overwritten with MIUI, you'll need to reflash RR + GAPPS + Magisk too before you reboot in to system...
Thx, but can I assume that the update has now been carried out successfully, even if this vendor error has occurred?
what vendor error? if your system is booting and working ...
its said: "Failed to mount '/vendor' (invalid argument)" , writen in red !
if it's not showing permanently, all should be okay
Thank you Jeryll !!
Jeryll, a last question that has nothing to do with the firmware topic in itself: My RROS (8.6.6) is encrypted. If I want to update to 8.6.7, should i decrypt first or can I just flash the new update via recovery?!
just dirty flash 8.6.7 over 8.6.6 and reboot to system, check if playstore is working and if magisk is present (optional depends on you using google stuff and root) if needed reboot to recovery, reinstall gapps and magisk ... that should work... I was unable to do clean flash of RR on decrypted storage...
Jeryll, you made my day again !! Many Thanks!!!
Greeting H0RDAK
Hello!
I am on an older version of Android 11 and I would like to install the latest Android 11 OTA without losing root and TWRP.
I know that I could just manually flash the lasted Android 11 firmware, then re-install TWRP and Magisk, but this would mean losing all data and having to reinstall apps, restore backups, etc...
So I was wondering if there were a quicker way to install OTA updates without losing data and root.
I know that there are many articles on the subject but they all refer to a previous version of TWRP and Magisk. Because TWRP 3.6.0 sports a completely revamped codebase I would like to know what is the latest recommended method if any.
This is my system info:
Android 11 sargo-rq1a.201105.002-factory-2433e0c0
Magisk v23
TWRP 3.6.0-11_0
Japan region
PS I do not intend to update to Android 12 yet
I ended up flashing the latest version of the stock firmware and reinstalling TWRP and root. However if you have a solution please post it for future reference.
I was looking for the same thing, didn't find any good solution, however, you can edit the flash-all script so that it doesn't wipe your data (remove the -w argument if I remember well).

The flashall script will still remove TWRP and root though, right?

Yeah it does, you have to reflash them after
It's annoying that we can't choose the OTA android installs, it has to be the latest one. On some phones you can choose a local file, but I didn't find a way to do so with a pixel 3a.
If you were able to do this, in theory you could just flash the magisk module for twrp retention and preflash magisk on the unactive partition after installing the ota but before rebooting. Then just reboot and you keep everything.
I'm not ready to update to android 12 either (gravitybox, twrp), but I'll try then...

I don't understand. Just flash the Full Factory OTA zip in TWRP. That won't remove any data. And you can just check the box to "Automatically flash TWRP after zip" so that you'll keep whatever TWRP you're using. Then you just have to reboot recovery (so that you're on the updated slot) and flash the Magisk APK in TWRP. Reboot and profit.
P.S. This post belongs in Q&A.

I wondered if you could do this, apparently TWRP doesn't recommend it.
Also I had no idea how this works on a device with A/B partitions. Does TWRP automatically flash on the inactive partition?

That 'recommendation' is specific to incremental OTAs. Also, it not generally being supported isn't the same as it not being recommended.
TWRP will install the zip to the inactive slot, and then when you reboot, the device will automatically boot into the updated slot.
Thanks for the precisions, I'll know for the next time. TWRP really is awesome
hi everyone, i flashed pixel 3a to android 12 and now my imei is 004400.... and no service ..... what should i do?
