OnePlus 9RT is a high end smartphone powered by Qualcomm 888 Processor. In the last few days, I have seen that many people bricked their OnePlus 9RT by flashing the firmware via fastboot, if you are one of those then you can try below fixes to fix it.
Note:
- avoid downgrade from android 13 to 12
- don’t use python fastboot ofp flash tool on this device
- don’t switch region, if you don’t know how to do test point
- don’t flash any ROM from fastboot, if you don’t know how to do test point
Solution:
- if soft brick after android 13 upgrade, try to flash following partition
Disclaimer:
- flash at own risk, because you may face hard brick (stuck at edl/black screen)
fastboot –set-active=a fastboot erase userdata fastboot flash recovery recovery.img fastboot flash boot boot.img fastboot flash dtbo dtbo.img fastboot flash super super.img fastboot flash vbmeta vbmeta.img fastboot reboot bootloader fastboot –set-active=b fastboot erase userdata fastboot flash recovery recovery.img fastboot flash boot boot.img fastboot flash dtbo dtbo.img fastboot flash super super.img fastboot flash vbmeta vbmeta.img fastboot –set-active=a fastboot reboot
or you can use single code for both A and B slot like this
fastboot flash partition-name_ab 'filename'
