I used your fastboot guide yesterday to recover my phone but I accidently flashed a newer version (9.0.10) then I had (9.0.7).
Do I need to reflash my device? If so with what method?
Steps I did:
1. Boot TWRP and wiped all except Internal Storage
2. Reboot in to the bootl;oader
3. Unpacked 9.0.10-OnePlus6TOxygen_34_OTA_017_all_1812111237_f52c4612-FASTBOOT.zip
4. Used flash-all.bat
5. Phone rebooted and working
I did not used TWRP because it did not show the correct internal storage??? If antone knows how to fix that please let me know using latest blu_spark TWRP
Blue spark twrp is only for op6, you need of op6t twrp, official or unofficial is the same
