EFJ 5100ES Bootload Stuck

Post by gatekeep » Tue Aug 08, 2017 11:09 am

I picked up a EFJ 5100ES Model II and was told it was sold as-is as a parts radio only. The issue being that it would lockup at the EFJ boot screen. I attempted to upgrade the firmware in this radio thinking perhaps the firmware was corrupt somehow. However, after flashing the radio is now persistently stuck in bootload and won't really accept firmware anymore. The upgrader software DOES seem to write and flash the application code but it doesn't appear to take on the radio. I fear the UI board is trashed, and I have no real feeling its correctable, not a big deal. But I was just wondering if anyone has run into this sort of situation and has any ideas.
