[OnePlus 7T Pro (Regular & McLaren) Q & A] RASEVEN:
Hi all, i wanted to remove my RR Rom, which was draining a lot battery.

But when i downloaded a new rom (Paranoid Android) and followed the fastboot commands i encounted an error.

7T PRO\payload_dumper-win64\payload_output> fastboot flash system system.img

target reported max download size of 805306368 bytes

Invalid sparse file format at header magi

So i tried to revert back to stock with this tutorial ( https://xdaforums.com/oneplus-7-pro/how-to/rom-stock-fastboot-roms-oneplus-7-pro-t3931424 )

But now i am getting these errors:

error: failed to load 'images.zip': No such file or directory

Press any key to exit...

But the images.zip is there , i can see it.

Also when i try other flash ables .bat files:
