The Restoring of Bricked OnePlus 8 Pro
About 2 min
- I received the OTA update from OPPO which allowed me to upgrade the current ColorOS 12.1 to ColorOS 13.
- I unpacked the update, installed Magisk to another slot as usual and restarted.
- Having no awareness of what I have done, I found that the reboot process was interrupted. After the OnePlus logo page, the system entered the bootloader and stuck in it. Neither rebooting nor entering the stock Recovery could solve the problem.
- First I thought that maybe flashing the TWRP and remove the Magisk conponents in system directories could work, but when I found the TWRP images, they were not even compatible with Android 12 and made the recovery of my phone totally destructed.
- Then I was seeking for the unpacked full images of ColorOS but nothing was found. OPPO had a strong control of the ROM and no unpacked image could appear on Internet.
- I finally gave up and started to seek for other's help.
- I went to the OPPO Customer Service next morning, but the staff told me that their only policy due to this situation is force restoration of the whole storage, including
/sdcardpartitions. I was extremely upset listening to this and left there.
