Well, color me surprised, but after getting the phone back in an almost normal state (Android flashed back on it with the official image from Fxtec - and a 99% broken fastboot implementation in the bootloader), my phone actually has it's IMEI still intact (The one I see with *#06#*, I haven't tried to check the second one yet) and everything works as it should, so apparently it is possible to overwrite the persist partition without any issue ??? 🤔

Might be a long shot, especially given how long it's been since you posted this, but do you have a copy of the perist.img you flashed? I could need one to flash on mine as well, even if it means loosing my IMEI ¯\_(ツ)_/¯
