The Radio Information Board

I HAVE A EFJ 242-5575-810HA4 WHEN I BOOT IT UP IT SAYS BAD F1 FMT IT WONT DO ANYTHING ELSE BUT BOOT UP IN BOOT LOADER MODE
DOES ANYONE HAVE FIRMWARE FOR THIS OR A DSP I COULD WRITE TO IT OR IS THAT A HARDWARE ISSUE THE F1 BOTTON WORKS THE BACKLIGHT TURNS ON WHEN I HIT IT
ALSO WHAT VERSION OF PC CONFIGURE HOULD I BE USING

Bad File Format is the error you are seeing. It means one of 3things:
1. It is an older firmware level where upon writing a new codeplug there was not a backup copy stored in flash, because the code did not support it and the main one became corrupted and could not operate.
2. The main and backup copy are both corrupted
3. While doing a firmware update, the code updater stopped, or communications was otherwise stopped after the firmware update was complete, but before the codeplug was update to support the new file format level.

In any case the way to fix it is to write a new codeplug to the radio with the correct version of PCC.

I.S.
