Hi,

I own a KB2003 model of the 8T, but with a KB05AA build. Is it possible to change it over the classical EU build, KB05BA ? I have some bugs and weird issues, so I'd like to try the other build, which seems to have a little quicker updates to. Can I just use the local update function with the new EU firmware ?

Thanks !

Thanks to @HipHopAnonymous3 who not only took the time to reply to me but also to upload the file I was able to upload to A12 C.15 and then via OTA to C.20.

Can the downgrade zip be flashed through twrp ? and can the global firmware flashed on KB2007 which is converted to KB2005 ?
[OnePlus 8T Guides, News, & Discussion] BillGoss:
You cannot use TWRP if you're on OOS 12. But you should be able to use it if you're on OOS 11.

So procedure like this?

OnePlus is rolling out a bug fix update for the OnePlus 8, OnePlus 8 Pro, OnePlus 8T, and OnePlus 9R. Read on to learn more.

Inside zip file open "payload_properties.txt" and change one line from:

And save it (I do it at computer).

Then update by OP Local upgrade app.

"fixed" installing the latest apk
[OnePlus 8T Guides, News, & Discussion] Gyalist:
I had the same problem with Netflix, KLCK, KWGT, and KLWP. This was my solution:

Turn on Aeroplane Mode

Clear all DATA from Google Play Services & Play Store

Reboot

Turn off Aeroplane Mode and re-enable Play Store settings. Depending on your connection it may take a minute or two for your data to be downloaded from the Google servers. Play Protect certification should now show "Device is certified" and your apps available once more. You will also need to re-enable your backup to Google One.

Sadly this didn't work for the Netflix not being found, however I have found a fix for this.

Check if Android System Webview is on latest version, if not update that first.

Clear cache both from Play Store and Netflix.

Reopen Netflix and Play Store.

Hi All,

I did according to this post:

1. Used OPLocalUpdate_For_Android12.apk for update

2. Installed magisk 24.3 and patched boot.img

3. Restarted to fastboot mode and flashed patched boot.img to slot a and b.

But when I try to restart phone it always go to fastboot mode.

Can I solve this problem without loosing data in any way?

Please point out me
[OnePlus 8T Guides, News, & Discussion] ruszok:
Change to oryginal boot.img

Should be:

2. Run Magisk

3. Flash Magisk at inactive slot

4. Reboot

First releases of OOS12 have overheating issue. I think now is ok. Risk is less then at the beginning. But no guarantee - this is the "new" OppoPlus, so you know...

I want to change from KB2003 (EU) to KB2005 (NA) - because EU updates are month later. But Oppo don't give full OTA to NA region. I need c.21 full OTA. Maybe someone can create it from full c.11 + incremental OTA's?

[OnePlus 8T Guides, News, & Discussion] dahawthorne:
I see that some people have managed to upgrade to C.33 Perhaps one of you could help me understand why I can't.

I'm on C.21 (About device/Version) or C.20 (Oxygen Updater app) - no idea which one is real.

I've downloaded the full 3.8GB C.33 version as mentioned in the Telegram chat, but with oplus_update_engine_verify_disable set to either 0 or 1, I still get "Verification failed". ADB Sideload also refuses to install C.33 ("kInstallDeviceOpenError").

Any suggestions would be appreciated.
[OnePlus 8T Guides, News, & Discussion] xstefen:
I ended up having to download mine via OP Updater app, and install it with the Local Upgrade apk
[OnePlus 8T Guides, News, & Discussion] dahawthorne:
Thanks. I tried that (must be the eighth time I've downloaded it) but unfortunately the same "Verification failure". Oh well...

The strange thing is that the failure happens within a fraction of a second. It can't be checking the file hash, because that would take longer. Very odd. And very frustrating.

Edit next day. Eventually I messed around once too often and got a Chinese & English message saying "Phone corrupt; customer services can fix", which was worryingly unresponsive to any button presses. So I used MSM to restore A11, then local upgrade to C.33. Need to start setup all over again, but at least I'm getting there.

But really, what a ridiculous palaver just to upgrade. OP need to look at their upgrade path, since a less-experienced user would have been totally up the creek.

[OnePlus 8T Guides, News, & Discussion] BillGoss:
I have NA on one slot and EU on the other slot and I can switch between them. This is only because I've been testing TWRP 12.

I make sure that I flash the logical partitions (in super) and the non-A/B partitions (mdm_oem_stanvbk, spunvm) in fastbootd before booting.

So, my answers would be: Yes.

And, because they both have the same encryption keys, I don't have to touch my data partition and the phone happily boots with all my apps running.

If you've "tried everything" then I guess you've tried:

- and using the enhanced fastboot tool in https://xdaforums.com/t/tool-windows-fastboot-enhance-payload-dumper-image-flasher.4310553/

Good day everyone!

I would like to request some assistance. I'm on a Oneplus 8T, currently on OOS 12 C.35. I used MSM tool yesterday to go to OOS 11 from Havoc OS. I want to flash a custom rom but I'm told that I need to have OOS 12 on both slots of my device. But in order to do that, I was told that I need to flash the full rom zip file of my OOS 12 version. But it seems that the full rom zip for C.35 is not included in the links on the first page. Can anyone help me ?
[OnePlus 8T Guides, News, & Discussion] BillGoss:
They LineageOS installation instructions have a zip to copy partitions so that both slots have the same firmware. You could use that.
[OnePlus 8T Guides, News, & Discussion] burislavak47:
If I do that, will I still remain on OOS 12? Or should I follow the instructions of the rom that I want to use like for Nameless?
[OnePlus 8T Guides, News, & Discussion] BillGoss:
It doesn't affect the version you're on. It just copies the firmware from your current slot to the inactive one.

I've never used Nameless. And installation instructions for custom ROMs shouldn't be discussed here, but in the rom's thread.
