Just wanted to provide my experience with KB2003 11.C.15 (Latest EU version updated over "local upgrade", downloaded through "Oxygen Updater") I converted from TMO with MSM Tool ages ago and have had no issues until this last update. Now my fingerprint sensor doesn't work, the local upgrade option is unavailable through Settings > About device > software update, my modified APN settings result in loss of mobile data (fixed by changing APN protocol to IPv4/IPv6, but results in undesired effects), and OEM unlocking was disabled after update as well. I'm reluctant to unlock OEM bootloader again, as I'm sure I'll lose my data.

Update: after searching around, most of these issues were related to magisk and android 12.

Update apk (to do local updates in the future) - https://oxygenos.oneplus.net/OPLocalUpdate_For_Android12.apk

Fingerprint fix - https://xdaforums.com/attachments/safetynet-fix-v2-2-1-ob1-zip.5558711/

The OEM unlock in developer settings didn't clear my settings

How about 5G? I had 5G on T-Mobile and Telus Canada on the T-Mo to EU build but it disappeared from Telus after further updating. Converting to the NA/Global returned the 5G for Telus but only for Android 11. I didn't test for 5G in Telus with the NA/Global Android 12 because the firmware upgrade disabled that SIM slot with no way that I had found to re-enable it without resorting to unlocking the bootloader and rooting, which I don't want to do.

My 5G option is showing up for one of my sims, but not the other. The other one I am not using, so I don't think the 5G option will show up for that one.

KB2003 EU. 11_C.15 version. Mint Mobile on my secondary SIM not using data.
[OnePlus 8T Guides, News, & Discussion] GraveDigger176:
I was für 2 days on the KB 2003 EU 11C15 ROM. And I was not impressed of it, only good thing was that 5G works now on O2 Germany, my first Sim is Telekom the 2nd is O2 and both works the rest of the ROM is really not good. So I decided to go back on oos 11 and flash a custom ROM back now i'm happy again 😂😂😂
[OnePlus 8T Guides, News, & Discussion] Dior DNA:

nevermind, I had to use MSM and restore an old OOS, then update again to OOS12. thanks
[OnePlus 8T Guides, News, & Discussion] Gibberish:
I was on the EU ROM (original T-Mobile 8T) with working dual SIMS. Got the update message and updated and ended up with KB2003_11_C.15. HOWEVER, now the second SIM is grayed out and does not work though it shows the phone number (of the second SIM). Should I be switching to KB2003 EU_C.15 to regain the dual SIM function?
[OnePlus 8T Guides, News, & Discussion] jcsww:
That's the issue I had with the T-Mo version on the Global/NA firmware. Definitely sad to hear that issue is still a problem, especially on the EU firmware.
[OnePlus 8T Guides, News, & Discussion] Gibberish:
Since the dual SIM is kind of crucial for me, should I go back to the the EU Android 11 version? Thanks.
[OnePlus 8T Guides, News, & Discussion] jcsww:
That's what I did. MSM Tool back and don't update to Android 12.

[OnePlus 8T Guides, News, & Discussion] Sting1971:
Android 12, C15. The update is C16
[OnePlus 8T Guides, News, & Discussion] BillGoss:
C16 is the A12 update for OOS 11 EU.

(My mistake) - C16 is an incremental update for C15.

C15 was is an A12 update for OOS 12 C11 IN.

(Corrected)

This is my Android version, the update is C16

If i flash a downgrade file given in the OP through there, will i successfully downgrade? Or is there any possibility of me getting bricked again?
[OnePlus 8T Guides, News, & Discussion] BillGoss:
From a conversation in this thread https://xdaforums.com/t/downgrade-to-os11-failing.4437413/ it seems that you have to use the downgrade zip that corresponds to the version of OOS 12 you're running.

In other words: EU downgrade on kb2003, NA downgrade on kb2005, and IN downgrade on kb2001.
[OnePlus 8T Guides, News, & Discussion] PurppleMonkey:
Hi,

Is there a way to do a "clean install" without TWRP ?

I did a local update on my KB2003 (C.15), and i want to do a clean install. Can i follow these steps ? :

1) Download C.15 and save it on my computer

2) Full backup of the phone --> With adb ?

3) Backup apps --> With TB

4) Full erase (cache, data and system) --> With Adb, but how ?

5) Flash new kernel (A12 friendly) and C.15 provide here --> With adb ?

6) Restore root --> payload dumper method

7) Restore all my apps --> Through TB

Have a nice day :)
[OnePlus 8T Guides, News, & Discussion] BillGoss:
If you're already running C.15, you can simply use Settings>System settings>Backup and reset>Reset phone>Erase all data. This will wipe /data (wipe all apps and all user data) leaving you with a clean install of C.15. If you're rooted, you'll keep root but will need to set up the Magisk app again.

My personal preference for backing up is:

- Swift Backup (available from Play Store) for backing up apps and their data

- ADBsync sdcard Backup from https://xdaforums.com/t/tools-zips-scripts-osm0sis-odds-and-ends-multiple-devices-platforms.2239421/ for backing up and restoring data from /sdcard to PC.

Hi !

I can’t update with the C16. I’ve installed the India Android 12 update instead of the EU version when I was on Android 11. Since there’s now an official Android 12 ROM with the C16, I wanted to get back to the EU ROM but the verification always fail.

EDIT : I am currently on the C15 (India) ROM.

C.15 KB2003 here, Czech republic. Just checked system updater. Nothing new.... i hope to see a full build posted here soon!

I had to force the Qualcomm app ( quick connect device ) update to the last version 2.5.23 to avoid heavy battery drain while training on my rowing machine. You know smart watch + concept app + connection to D2. In 30 minutes workout was draining 40% of battery. Now is kinda ok, but I'm curious to see what improvements in battery life will have C.16.

So it looks like for OOS 12 links to older version stop working when a new one is relased, which is different to OOS 11 links. I guess it make sense to archive and upload the latest version of OOS 12 going forward, in case anyone want to downgrade to an earlier one.

And its correct. At first i updated with full zip and i ended up with C.20/C.21 missmatch : Gpay not working, Playstore not certified.

So i downgraded my phone (again) and : A11 => full zip C.16 => OTA C.20 is the way to go : Safetynet ok

This is the only way to pass the 93% milestone) I don't know why the firmware was not installed from the computer, I also downloaded it via oxygen updater.
