Do you still have access to the redboot bootloader?
If so I think you can try to reflash with the appropriate binaries.
Also maybe try openwrt binaries from the opengemini blog.

Not done this for a long time so my recollection is a bit rusty.

The firmware flash option most likely did write bad code in the flash memory address space where redboot resides.
Seems You already know that JTAG flashing is the only way to unbrick the NAS box.
Not done JTAG myself but HWGuru may be able to help if you get into trouble.

Did you save any binaries with the MTD driver before the update disaster?

Maybe first use redboot to flash the MTD partitions with known good kernel and ram binaries.
eg your previous firmware.
Don't have an edimax but are all the entry points for the MTD partitions correct for the edimax firmwares?

Other thought is to compare the log with that found on the open gemini blog.
Seems to me lots of drivers aren't being initialised.
