After I flashed this (ddr0), it keeps booting back to fastboot. Also, it shows the Product_name as kona. Shouldn't it be kebab?

I power it down and turn it on and goes to fastboot.

Any ideas?

Can you give me a log? and what ADB Fastboot package did you used?

How to generate logs in fastboot? Mine is NOT booting to recovery or system and only boots to fastboot.

fastboot version 31.0.3-7562133

Can't access edl mode, can't use Msm...

Well, I got into edl mode and flashed MSM to go to stock. Then, I flashed latest Nameless AOSP in the recovery and all good. Whew, wasted couple of hours...

Oh well, I just didn't realize that the blobs from A12 were not used by the AOSP ROMs - how could they use it as it was just released yesterday. lol

I had the Swift Backup and restored everything and all good now. Live and learn I guess!

EDIT: Clarified my steps: edl to stock (MSM) to nameless.

How you flashed nameless with edl mode?

No, I meant I flashed stock (edl -> MSM) and then flashed nameless in recovery. I thought it's understood that when you edl, you go to stock.

Since I Updated to oxy 12 I cannot flash any rom, I went back to oxy 11 and nothing at all I cant flash anything when I flash a rom I go in fastboot always and only MSm tool can restored it, why?

I just did that exercise today and it works. Steps:

1. I went to OxygenOS_11.0.7.9 via MSM.

2. adb reboot bootloader

fastboot flash recovery recovery.img (got it from nameless AOSP)

3. fastboot reboot recovery

4. Flash the latest OOS 11 firmware:
adb sideload fw_kebab_OxygenOS_OnePlus8TOxygen_15.O.31_OTA_0310_all_2202182359_ca105dab55fd44e6_11.0-DDR0.zip

5. adb sideload Nameless-AOSP_kebab-12.0-20220328-1715-Official.zip

6. Factory reset in Recovery

7. Reboot

8. After setup, flashed Magisk in recovery.

The reason for this is that MSM only fixes up the A partitions. It doesn't touch the B ones.
This means that when you flash a rom after restoring OOS 11, you will end up on slot B which still contains the OOS 12 firmware.
The solution is to go back to slot A, reboot to recovery, flash OOS 11 again so that both A and B are on OOS 11 firmware.
Or, while on slot A, flash the Los Copy Partition zip, which will copy the A partitions across to B.

Yes, that's correct. That's why I posted my steps above where I flash the latest OOS 11 firmware, which flashes it in both the slots and later, when you flash custom ROM, it works.

And now others will understand why it works.

Hi!

That file you posted (OnePlus8TOxygen_15.E.15_OTA_1032_all_22011904_381685994.zip) I guess is a OOS11 Version.
So, if you are on OOS12 now and want to go back to OOS11 you can use the MSMdownloadTool to flash back to OOS11 or I guess somewhere there are downgrade zip files to get back to OOS11 as well.
