analogRF:
so, except for any other hardware fault (RAM, power rails, etc...), I think most likely your flash memories are corrupted in a "bad" area which prevents the bootloader from running.
Possibly the upgrade was updating the bootloader and something went wrong during that period...

nexus:
Copy that; thank you! I'm going to see if I can find a cheap parts unit or main board online. Hopefully replacing the flash chips should restore bootloader function.

Let this be a lesson; do not update using the thumb drive application!  |O

analogRF:
be very careful about part units on ebay (all of them but particularly those from alltest)
most of these have all of their memory chips (of all kinds even SDRAM) and sometimes even their FPGA and CPU cut off from the board by cutters

nexus:
Yup, I saw that alltest has a few for sale. The ICs they indicated as removed (well, more like ripped off brutally) were the SDRAM chips on the top side.

I asked them if the two chips of interest are still on the board.

nexus:
BTW if anyone has a parts unit or a motherboard laying around feel free to PM me ;)
