GL-XE300 Uboot broken flash update and stuck in loop

Hi, I ran a flash update form the UBoot interface and the modem is now bricked, stuck in an updating loop.

Loop step 1: At the start of the loop the Wifi LED light comes on and the interface is accessible saying the updates is in progress. Then after a few mins
Loop step 2: The LAN LED light flashes quickly for about 20 sec and the web interface is no longer displaying.
Loop step 3: LAN and Wifi LED rapid flash simultaneously for about 20 seconds
Loop step 4: LAN, Wifi and 3G/4G simultaneous single flash
Loop step 4: LAN, Wifi, 3G/4G and WLAN simultaneous rapid flash for about 5 sec
Loop step 6: Device reboots return to step 1

Trying to force a reset back to the Uboot interface yeilds no change. SSH interface is also down.

Any assistance would be appreciated.

Kind regards
