Alex, problem was solved!!! This user had reported to me. He patched SW in device directly to follow not original instruction and he do something wrong obviously. I get to him direct link to you page Boss and all alright now!

I think there is way to send its back but as dummy.

So I can extract JPEG files, I can replace original and modified files in HEX editor.
1) But how can I modify JPEG file for transparent color?
2) Is only the same size in byte is required for edited file for substitution?

Sorry for the delay. Now flash the navigator to get the file GUPDATE.GCD size of 9,467,284 bytes. Took him to the Computer and patched. The work program was two seconds. Get files GUPDATE-Patched.GCD 9,467,284 bytes. Remove from navigator file and GUPDATE-Patched.GCD copied it, changed his name to GUPDATE.GCD. Disconnected from the computing system. Reload. Two or three seconds and the display card error. AllexWhiter. Your file does not work.The result is zero.
