Understood, but you did not post which method that you used beginning with each command.
I followed the instructions post on this thread.

I followed the instructions post on this thread.
There is more than one way to approach this [take both methods with a grain of salt].

Determine which Slot you are on and switch Slots [optional]

Follow the first 4 steps of the original instructions

Start by extracting the ROM inside of a folder on your desktop

Rename the ROM file to the system such that the complete name becomes “system.img”

Ensure that the vbmeta file is present inside the folder and your smartphone will be booted to FastbootD Mode

Then, use the below command for flashing vbmeta and disable the verification check
fastboot --disable-verity --disable-verification flash vbmeta vmbeta.img

Erase the system partition through the below command

fastboot erase system

Use the below command for flashing the ROM onto your OnePlus
fastboot flash system system.img

Once it is done, boot your device to the newly installed ROM using the below command
fastboot reboot

Determine which Slot you are on and switch Slots [optional]

Follow the first 4 steps of the original instructions

Start by extracting the ROM inside of a folder on your desktop

Rename the ROM file to the system such that the complete name becomes “system.img”

fastboot set_active a or b

fastboot erase boot

fastboot erase system

fastboot flash dtbo dtbo.img

fastboot flash system system.img

fastboot flash vbmeta vbmeta.img

fastboot flash boot recovery.img

Reboot into recovery

After which, try ADB Sideloading

N.B.: Even if you see one of the below error messages, then it usually signifies a successful installation and you could reboot the device to the OS without any issues:

  • Total xfer: 1.00x
  • adb: failed to read command: Success/No error
  • adb: failed to read command: No error
  • (~47%) adb: failed to read the command: No error
  • adb: failed to read command: Undefined error: 0

Ok, I finally had success. I flashed the c.33 via local update twice reading somewhere that it will get both slots A and B. I also did this for the recovery.img
I don't know about everyone else but this was so hard for me. Glad there is a community with people like you that are super helpful.

    I've posted how I managed to do it on OOS12 firmware here:
    Hi everyone, I wanted to inform you that the wide camera mode does not work in the stock camera
    You have to disable something like 'ultra wide lens correction '.. then it starts working 👍

    Thanks it helped👍
    Can I also follow this if I am on the Nameless 12.1-20220708-0926-Official Build? :)
    Yes I think so, you just need to check if that build is based on OOS11 or OOS12 Firmware.
    Using 9R LE2100 (China version, but with OOS)

    Switched from stock OOS 12, C33 version to this amazing ROM.

    Everything works!!! Fast charge, refresh rate, winevine are all OK. Battery life is great. Thank you ROM DEVs :)

    Just some notes here to help others who might encounter issues:

    - I made sure both slot have OOS 12 C33 firmware by forcing the local update for C33 twice.

    - I flashed recovery to both slots with:

    fastboot flash recovery_a recovery.img
    fastboot flash recovery_b recovery.img

    The whole process went smoothly, without any hiccup. Not even being stuck at 47% as mentioned in the original guide. The whole thing just passed cleanly.

    Device Changelog

    I went through this yesterday evening and hit many snags and confusions due to looking up different posts... So I thought I'd write down my process in the hope it helps others.

    Before you begin
    • Backup of all Data, Fully charged battery, really backup all your data
    • Know how to use Windows command prompt, move files and folders about in explorer (or know how to set the PATH variable)
    • Follow this guide at your own risk!


    1. Install ADB + QualCom drivers. Reboot is required
    2. To check, connect phone to PC, reboot phone to fastboot, check device manager for anything with a yellow "!". Then repeat when in recovery. If you have issues here Fix this BEFORE continuing

    On PC
    1. Extract Nameless ROM zip
    2. Extract payload extractor zip
    3. copy payload.bin from ROM to payload_input folder where you extracted payload dumper
    4. Command prompt -> run payload_dumper.exe (takes about 5 minutes)
    5. In the payload_output folder will be .img files. You'll need these later

    Roll phone back to Android 11 with MSM tool
    1. Follow msm guide: https://www.getdroidtips.com/oneplus-msm-download-tool/. Took 900s to complete
    2. Complete first boot setup sequence, don't restore any data, skip as must as you can. Don't perform system udpate. Stop apps updating.
    3. Install Oxygen Updater -> Download KB2003_11_C.21 (Android 12) ~3.88Gb
    4. Whilst that's happening: Enable Developer Mode, Enable OEM Unlocking, Enable USB Debugging
    5. Once download complete, copy the update .zip file from root of phone to your PC
    Unlock bootloader
    1. In command window: adb reboot fastboot
    2. In command window: fastboot reboot bootloader (as soon as you press enter to run the command type and run the next one so it's waiting)
      • fastboot oem unlock
    3. Accept the text menu and phone will reboot and wipes itself
    Update phone to Android 12
    1. Clear setup asap, bypass / skip / ignore all you can
    2. Copy downloaded oxygen update from PC to root of phone
    3. Local install using Oxygen download file (ignore the system update) + reboot
    4. Enable USB Debugging
    5. In command window: adb devices -> ensure you're authorised
    6. In command windows: adb reboot fastboot
    On PC
    1. In command window: open the payload_output folder (with the extracted .img files from earlier):
      • fastboot flash boot boot.img
      • fastboot flash --disable-verity --disable-verification vbmeta vbmeta.img
      • fastboot flash --disable-verity --disable-verification vbmeta_system vbmeta_system.img
      • fastboot flash recovery recovery.img
    2. Use fastboot menus to reboot to recovery (new blue one)
    3. Press "Install update" -> "ADB Sideload"
    4. In command window: adb devices - ensure it says "sideload" and not "unauthorised"
    5. In command window: adb sideload copy-partitions-20210323_1922.zip
    6. Reboot recovery from menus on phone
    7. In command window: adb devices - ensure it says "sideload" and not unauthorised
    8. In command window: adb sideload Nameless-AOSP_kebab-12.1-20220723-1310-Official.zip
    9. Click back arrow in recovery, then click "Factory reset" -> "Format data/factory reset" -> "Format data"
    10. Click back arrow in recovery, then click "Reboot to system"
    If you miss a step and boot the phone it's likely not going to be stuffed. In this case, force it back to EDL mode (adb reboot edl) or hold the up + down volume buttons for ~40s and start with the MSM tool again.
