UE55J5500 firmware dump
Our reckless team have dumped both SPI flash and eMMC from 55J5500. Here are some pieces (a full dump is too big, 4GB)

Re: UE55J5500 firmware dump
W25Q40B SPI flash dump. It has reversed byte order in dwords. Looks like this is a complete firmware for some separate lightweight Cortex-M core. It listens to some simple commands on UART (connected to main CPU ?).
As far as I understand, the main multicore subsystem boots from eMMC boot partition directly.
There is a key for *.msd upgrade files in USB updater module, but it is encrypted via some hardware ("se" part of "demux" module in device tree).

Nice work. Check PM
I do NOT support "latest fw" at ALL. If you have one you should block updates on router and wait for it to STOP being "latest":)

The full firmware dump files have already been made available to a few folks, courtesy of flowswitch and team. You know who you are. Point us to the repository, if it's still online.
