I had that exact same screen coming up on mine when I tried to flash Mirek’s v6.1 rom (air ii version) to my Air III. After trying five times and getting the same thing on the screen, I realised downloaded TechKnight’s version of the MFG and it worked.
TechKnight had a slightly different PID (or SID… one of them) to the ones that were written in the official Teclast tutorial in Chinese. Once that PID (or SID) changed, it worked and flashed successfully.
