Can't flash system.img in fastboot mode on 2012 KFHD 7"
Please help. I had Omni rom running fine. One day I turned on the tablet and got stuck in a bootloop. I tried to boot into twrp and it just sits there on the teamwin logo and wont go into twrp. I have factory cable and can get into fastboot, but the system.img will not write to the tablet. I have tried KFFirstAide and KFHD System.img Restore Tool and it will not write the system.img. I've tried multiple system.img, so it's not a corrupt file as the MD5 matches. Do I have a failed internal SD? I cant understand why twrp hangs either. UHHHHGGGG!!!
Here is what I get:
C:\>fastboot -i 0x1949 flash system system.img
target reported max download size of 1006632960 bytes
sending 'system' (907264 KB)...
FAILED (remote: : Write partition)

Any help would be appreciated.
