Having this issue with windows 8 x64 computer, works fine on my windows 7.
Any idea why it would do this at 94%.

It has this issue everytime I try to flash for the first time, when I select 'yes' at this point to erase completely, it flashes entire file again and finishes. Never seen this on my 32bit windows 7 computer and it's a real pain in the arse.

Small picture is small

Maybe difference in baud rate? Post whole log of nefmoto instead of picture. post both logs, win7 and win8.

you did not read log fully. log says attempting to erase last sector, failing, and then showing 100%. flash is incomplete.

even says 18 out of 19 sectors at the last part of log.

I solved this issue but i have not a green idea where was the problem.

If you have this problem reinstall OS , drivers /cable/ and app nefmoto software.  /  this help for me. /

If it is not possible on your PC install VM Virtual BOX and install all on virtual host and check it.  It should help.
