Hi guys! I'm the owner of the watch, OP is my husband who beat me to the punch posting here.
I received it yesterday. Took it out of the box, turned it on, and immediately it kept repeating the booting screen:
LOCKUP
BL 2V24
CHECK STORAGE
NO NEW FW
BOOTING
And then repeating that screen - loading in each line of text, flickering, repeat. I downloaded the nRF updater and tried to install the 2v25 firmware and the app suggested that it had worked (no errors, said completed etc) but nothing changed on the watch. We tried this several times, from both my phone (pixel 7a running grapheneos) and my husband's (stock pixel 9 pro), with the same result. Tried using the app loader website but neither my phone nor my husband's could find the watch using the browser Bluetooth connection.
Later tried using my husband's laptop which has Bluetooth using the Web IDE and I think the watch died during the attempt since it had been doing the screen repeat the whole drive home (first tries were at the Christmas gathering where I'd received the watch) but we didn't realize at first since we assumed it would power cycle during a firmware update. Once we figured that out and got it charged back up it's been on the BANK0 INVALID since then.
It never got to the initial splash screen. I took it out of the box, turned it on, and it kept repeating the LOCKUP etc screen before we did anything with it.
Husband is at work now but I'll be able to respond during the day. Any additional details that would help? Should I try using the nRF updater again? Don't mind having to do any resets or anything since I never got far enough to do any customizing.
