[Advanced] Installing factory Android image w/ SP Flash

I’m having the boot-looping issue when I try to install the factory image, but the instructions for that case seem unclear. ‘When its screen is dark’? The screen is always dark when the phone is off. Am I supposed to turn the phone on and then try to time connecting it after the ‘dm-verity corruption’ etc. message comes up and it starts turning the phone off again?

Hi @degraine - apologies for the delayed response. The trick for a boot loop is to keep the PC ready in download mode and insert the cable into the phone as soon as the phone’s display turns dark.

I have done all the steps correct, I have windows 10 and all files but its saying to select at least one ROM file and I have selected all files, Please help how can I fix this.
