  2. If you are unable to wipe your super partition or are getting the kDownloadError, reboot to fastbootd and wipe the super partition using fastboot wipe-super super_empty.img.

danger

For Chinese Variant Users (In case you aren't on the latest version of COS before flashing Nameless): If your SIM isn't detected after flashing the ROM, you need to flash the chinese variant (COS) images in fastbootd mode. Follow the instructions below for help with that:

  1. Boot into fastbootd using adb reboot fastbootd.
  2. Extract oplusstanvbk.img and modem.img from the latest COS firmware zip* (Instructions)
  3. Flash the images using:
fastboot flash oplusstanvbk oplusstanvbk.img
fastboot flash modem modem.img

* These images were not included due to the Chinese variant device facing network issues. These images would need to be updated when the ROM uses the latest firmware
