Maybe for some weird reason new update is installed to other slot, but not booted from this slot. Maybe you can try to change actual slot from slot_a to b or b t a.....

You will need fastboot and find correct options for finding out which slot used and change slot, but thats easy ;-)

Any chance at obtaining IN2025_C.33? currently in a bootloop due to [patching and] flashing the wrong boot.img (c.16), after updating to C.33 (via Oxygen Updater). now i dont have C.33 for IN2025 to flash stock boot.img. i can get adb access to OS. boot loops at 1+ splashscreen. sometimes makes it to home screen, but is inoperable and eventually kernel panics

[OnePlus 8 Pro  Guides, News, & Discussion] xtcislove:
So North America(IN2025) is reffered to as global and not Eu(IN2023)?
[OnePlus 8 Pro  Guides, News, & Discussion] nnwwtt:
Thank you for the instructions. I've been trying to do Option 2 since Option 1 doesn't work at all (on C.20, both C.21 and C.33 fail), but I can't get past abl:

Unfortunately not even fastboot flashing unlock_critical seems to work, that just returns a false Device already : unlocked!

I can still boot but connectivity is dead (no calls connect, wifi fails to enable).
[OnePlus 8 Pro  Guides, News, & Discussion] Danny1976:
First you have to extract the full OTA img with payloader. Then make sure you have commands for all the files that are extracted by the payloader. The commands list I posted may not be the same as yours. Make sure you compare the fastboot commands to the files the payloader extracted. I have my bootloader unlocked and I believe you need to have your bootloder unlocked to be able to do this.

Compare the fastboot commands to the extracted files. Let me know if you were missing some commands.
[OnePlus 8 Pro  Guides, News, & Discussion] nnwwtt:
I did it with payload_dumper, the files match. The bootloader is unlocked and further unlock_critical has no effect against that Critical Partitions error, that's the weird thing.
[OnePlus 8 Pro  Guides, News, & Discussion] Danny1976:
Now that you did the commands you may have fixed the verification failed problem. Try placing the Full OTA on your internal storage and doing a local update. If you go into settings and about it should show Official.
[OnePlus 8 Pro  Guides, News, & Discussion] Danny1976:
Can you do me a favor. I need the link Full OTA for the OP8 EU C.33 from Oxygen Updater. I messed up and I am stuck on the bootloader and have no way of getting the file. If you into the Oxygen Updater and in the settings change the model to OP8 EU Full OTA.... it should give you the link.

Edit:I just switched from slot b to slot a and was alble to go back before I updated.
[OnePlus 8 Pro  Guides, News, & Discussion] nnwwtt:
Tried. Still refuses both. Ugh.
[OnePlus 8 Pro  Guides, News, & Discussion] nnwwtt:
EU C.33 for OP8 Pro is here.
[OnePlus 8 Pro  Guides, News, & Discussion] Danny1976:
I have the OP8. I just posted the steps here, because it was affecting the OP8 and OP8 Pro. Send a screenshot of your about device and then the Up to date. It should say Official Version. What version does it say you are on? C.33 or C.21?
[OnePlus 8 Pro  Guides, News, & Discussion] Danny1976:
I'll try to see if I can help you out, but screenshots would help. I have to do some errands and when I get back.... I can try helping you out if you haven't solved it by then.
[OnePlus 8 Pro  Guides, News, & Discussion] nnwwtt:
Ah, sorry. The pro link is the one I have.

Another oddity: fastboot flashing get_unlock_ability returns 0, which would be false. But I can flash & root just fine, and fastboot flashing unlock/unlock_critical returns "Device already : unlocked!"
[OnePlus 8 Pro  Guides, News, & Discussion] Danny1976:
All the fastboot commands have to be successful. Did any of the fastboot command failed? You are on the C.21 and are trying to flash the C.33?
[OnePlus 8 Pro  Guides, News, & Discussion] nnwwtt:
I haven't been able to proceed past…

… due to it aborting with "Flashing is not allowed for Critical Partitions."

I've been able to get fastboot flashing get_unlock_ability return 1 (allowed) again (I forgot I had disabled bootloader unlock again in the dev options after rooting), but fastboot flashing unlock_critical, which *should* make that error go away, still returns "already unlocked".

Unfortunately it's not actually C.21, there is some bug in C.20's full install script for the European version that made itself falsely install as C.21.
[OnePlus 8 Pro  Guides, News, & Discussion] nnwwtt:
Oh, I'm an oaf. I thought after…

… I'm supposed to enter fastboot via Advanced again, not stay in fastbootd. Now abl can flash. I'll do the rest and report back.

Sorry!

*edit:* Well darn. Commands succeeded (except the DDR5 ones, not found on device), but now the device only boots into recovery.
[OnePlus 8 Pro  Guides, News, & Discussion] nnwwtt:
Well, that was a ride. I'm finally on C.33 now and connectivity is restored, thank you very much!

Notes:

I had tried to first flash C.21 (by accident, wrong folder). I got exactly the same messages as later when flashing C.33, but the device wouldn't boot.

If I may, some changes to your manual:

Maybe a note that people need to remain in the initial fastbootd – not enter the advanced/basic fastboot – would be good. The latter will fail over the locked partitions.

I'd add some linebreaks to the fastboot flash xbl* lines, so really nobody bricks their device by flashing the wrong variant.

I'd also put the DD5 xbl* lines in brackets since they don't actually apply and the commands will fail.

I got "invalid sparse file format at header magic" for each of the bigger/split img files, but it is a harmless warning.
[OnePlus 8 Pro  Guides, News, & Discussion] Danny1976:
Glad it worked out.... I have been in your place trying to fix the mess OnePlus did with labelling C.20 with C.21. It helps going back and forth with troubleshooting with someone, because it just helps processing the situation.

I'm installing C.33 now after Local update refused to verify both C.21 and C.33 because of C.20.

Edit: install went fine 👌
[OnePlus 8 Pro  Guides, News, & Discussion] stegg:
what are the exact steps you made?

I edited the file with 7zip as stated in the post, but my system updater (3 dots) stops with error "unable to verify update file"

I am currently with c20 EU version, Oneplus 8pro
[OnePlus 8 Pro  Guides, News, & Discussion] jimger:
Copy the file out of zip, change the value and copy it back to the zip. All apps I tried, failed to save the actual change from loading from the zip. So with copy and paste file back to the zip it worked
[OnePlus 8 Pro  Guides, News, & Discussion] ante0:
See reply above. I modified it using Total commander. All other apps failed 😂
[OnePlus 8 Pro  Guides, News, & Discussion] stegg:
Thank you both, but still unsuccessful.

I extracted the file with 7zip, edited it and rezipped (and verified it's written!), but my phone still says "verify failed", as if it expects some checksum somewhere.

I will try to update to c21 first, then Total Commander.

BTW I have root, don't know if it's relevant

edit, where hell is c21 for op8pro? first post doesn't list it
[OnePlus 8 Pro  Guides, News, & Discussion] ante0:
Are you using the 3 dot menu from Settings - About - (Up to date) OR the System update app? You have to manually install the latter. It shouldn't matter if you go C20 to C33 directly.

However, the program you use to modify the text file can matter. Use Notepad++ if you're on a pc and if you use your phone I suggest using Total commanders built-in editor.

System update app link: https://oxygenos.oneplus.net/OPLocalUpdate_For_Android12.apk

This will install as a standalone System Update app, open it and tap the 3-dot menu and tap Local update.
[OnePlus 8 Pro  Guides, News, & Discussion] stegg:
Dang, I did it! I tried several combinations of the above, and the only one that worked was:

1. download C33 via oxygen updater - advanced mode

2. copy update zip file to PC

3. edit payload_properties.txt with Total Commander (can't believe it!)

4. copy zip file back to phone

5. install the update via OPLocalUpdate_For_Android12.apk

6. reflash magisk (whithin magisk manager) in the inactive slot and reboot

now I am on C33, kept root, and am keeping phone (I was on the verge to throw away everything and purchase a S22+)

thank you all

(edit, this applied to my IN2023 with C20 that refused tu update to C21/C33)

I downloaded the most recent update for OP8P IN2025_11.C.33_1330_202207302311

When I try to payload dump, I get this error:

Traceback (most recent call last):​

File "C:\Users\Kevin\Downloads\payload_dumper-win64\payload_dumper.py", line 86, in <module>​

assert op.type in (op.REPLACE, op.REPLACE_BZ, op.REPLACE_XZ), \​

AssertionError: unsupported op​

This is how I got the boot.img on the last OTA so im not sure whats different about this one. Any ideas?
[OnePlus 8 Pro  Guides, News, & Discussion] Kalanyr:
Yeah, I had this problem too. It seems like they've changed the structure for the incremental updates because I tried to extract boot.img from it using another payload dumper that supports incremental updates and while it successfully extracted a boot.img the img was corrupted.
[OnePlus 8 Pro  Guides, News, & Discussion] Kalanyr:
Hmmm. A patched boot.img from the IN2023 C33 full OTA can't be used to boot IN2025 on C33 (from an incremental update) either.

That means the pre-patched image provided in: https://xdaforums.com/t/oneplus-8-p...epo-of-oxygen-os-builds.4084315/post-87251739 also doesn't work.

Edit - Its possible this is because I forgot to disable some magisk modules but I don't really see how.

ETA2 - Weirdly once I installed the incremental C33 for IN2025 , it turns out that my phone shows as IN2023 in it's about device and shows as being on build number IN2023_11_C_.33
[OnePlus 8 Pro  Guides, News, & Discussion] devildogwillbur:
I also tried to install the update and run magisk before resetting but the update won't get past 20%
[OnePlus 8 Pro  Guides, News, & Discussion] Kalanyr:
I have tested the following image and verified that it works (on an IN2025 incrementally updated to C.33 and thus showing as IN2023).

The patched image attached is done with the currently latest magick-alpha, so if you're not using that, I've also attached the boot.img I used so you can patch it yourself. In which case you should adjust the instructions appropriately

If it doesn't work, then

Turn on USB debugging and make sure it's authenticated and works and you access the shell

From a terminal window:

./adb restart fastboot

On the phone (if necessary) move to fastboot mode instead of fastbootd by selecting English -> Advanced -> Reboot to fastboot

On the computer, open a second terminal window and execute

./adb wait-for-device shell magisk --remove-modules

Then go back to your first terminal window and do

./fastboot boot magisk_patched-25202_ATMXx.img

If Magisk asked you to reinstall the non-hidden app and you did so, make sure you launch the app that actually has SU authority (ie the one you named, not the non-hidden app) and you should be able to do a direct install.

If that app still isn't showing Magisk having SU authority, then you need to:

./adb restart fastboot

Go into fastboot mode on the phone

./fastboot boot magisk_patched-25202_ATMXx.img

And then launch the app (sorry about this bit, I wasn't paying enough attention and failed to check if the reset from remove--modules go back into the on device image and did the fastboot thing by accident myself to test something else before realizing my startup sequence actually prompted for the pin)
