hi,

I tried a few times and all the time a can't read eprom from fis (a have same FF - i try by galep 3, vp-280 and simple pony programmer). I connected some like on your pictures. It's first time when I can't read, other versions I did without problems. What I doing wrong.....??


...when the radio is connected to power supply rRED diode don't pulse, maybe eprom in fis is destroyed and ALL THE TIME i read only FFFF
