Like in the summary: I was doing a typical custom ROM flashing and I did a backup file via TWRP. After approximately 4 hours I changed my mind and I decided to change my OS again to the stock one. Unfortunately, I've downloaded the potter version instead of sanders (all ROMs I'm saving are prenamed by the folder name before the download starts, for example, to Moto G5S Plus) and I didn't realize the mistake until sparsechunk.3 file flashing (first error showed here). So I have stopped the installation, I've flashed TWRP again with minimal ADB. I was pretty shocked when after pressing the 'Recover' tab my eyes saw a backup file of 12MB of size (literally, that was the size of a backup folder and the twrp terminal didn't show me any errors while making backup). Of course, I've tried to recover my phone from this backup but it was doing even worse. I've tried every possible way to repair my device (downgrading, adb, customs, rsdlite), none of them work for me, except for one: backup from another device made from only system + boot partition (tried this on a different device bricked in the exact same way). So there comes my kind request guys. I know that you all are making a great community and I want to ask you about one thing: can someone make a backup for device XT1805 reteu channel with OPS28.65 or higher for me? I put a beer (even two) for a person who will help me!
