I installed the gFlipper app on my computer, installed an sd card in the flipper zero. Formatted and mounted the sd card, then plugged in the flipper zero to update. Was told to reboot into firmware update mode, so I did and the update process started. After a few seconds the Flipper Zero powered off and the update failed.
Now I am unable to power the Flipper Zero back on at all.
Any help or advice would be GREATLY appreciated.
