Boot Loop after firmware upadate (2v17)

Hi I'm stuck in a loop after trying to update the firmware
I'm using the banglejs/gadgetbridge (0.73.0-banglejs commit 4f3472565), which said my firmware could be updated from 2v16 to 2v17

I tried updating, and all seemed to go well, but when I logged back into the app again - it still said I needed to update

So I tried again - and now I'm stuck in a loop

screen shows

watchdog
dfv zv1z

check storage
no new fw

booting...

Is there anything I can do ?
