Any updates from anyone?

I think I covered this earlier.
The issue I found was if you have the Mega 2560 instead of the older
1280s then if you also do not have the reset trace cut on the Arduino
mega it will not connect. it's because the auto reset takes longer on
the 2560 vs the 1280. It has soemthign to do with 1280s use FTDI and
2560s use an 8u2 for USB support or it could just be the 2560 takes
longer to get into code from reset.

I've had RepG crash a few times while updating my firmware as well.

LCD went blank, and nothing worked for a while.

But I kept trying to flash the firmware, pressing the reset and upload in different timing combinations, and it finally took.

ReplicatorG itself doesn't do the firmware download: it causes an independent
process to be launched and it waits for that process to finish. That independent
process runs a program named "avrdude".

As to fixing, you will need to figure out if the bootloader is really gone or
not. If it is, then you will need to reload the bootloader using an AVR ISP
programmer.
