Yes it is M001. I flashed unit previous with no problem. Card formatted to FAT32. Size of card to 32 gig or 16 gig depending on unit. Otherwise up to 8gig should not matter. booting clean from card so it is something else that went wrong. I unzipped 3 different rom flashes, so now I am doubting myself and wondering if on the 1.1.1 I may have extracted instead of 7zip. I know for sure two were 7zip but 1.1.1 was third and I am so used to winrar I wonder if that happened. Anyway it will not boot at all so it is moot. There may be one of those voltage zapping ROMS that if you mess something up they short out. and donuts to dollars it is all surface mounted.
