Success !!!
I have managed to downgrade the firmware on the GT-AX1100 back to RC2-9
You have to perform the downgrade from a client connected wirelessly to the router.
I used my phone and browsed to the router webpage and then was able to flash the RC2-9.
Figured since the wired part is borked and the wireless performs normal i should try it from a wireless client and it just worked !!
