And fanoush that firmware you made - that's just disabling the 32kHz oscillator and DC-DC converter?
yes, I just disabled both. Then I made another two for disabling each one but not sure @user159420 tried those. The builds on github are now expired but direct links to artifacts still work.
As I understand it the standard firmware just reboots in a loop with LOCKUP message and the one with those two features disabled works. It came with standard firmware, then @user159420 tried to update firmware to fix the reboot loop and for a while got BANK0 INVALID due to bad update, then managed to update correctly so the message is gone but still got reboots and then firmware with disabled DC/DC+32kHz crystal finally helped to get out of the loop.

Hi - I'm back now! Thanks @user159420 for being so patient with this and @fanoush for helping out so much with the new firmware.
And @fanoush that firmware you made - that's just disabling the 32kHz oscillator and DC-DC converter?
This is an odd one for sure - so right out of the box it was doing the LOCKUP looping thing?
Because as @fanoush said above you get to the bootloader screen if you hold the button for a bit too long when it's starting up (holding the button or leaving for 30s should leave the screen though) so that may have been a bit confusing right from the start.
Do you think it's possible that you might have installed a new firmware using that DFU screen, but maybe installed something like the firmware for a Bangle.js 1, rather than a Bangle.js 2 firmware? I guess that could cause the LOCKUP error - and then just putting the new firmware on that @fanoush supplied would have fixed it.
We test these all before we send them out (which includes installing the JS firmware on the watch, which yours should have had) so I can only assume that if there is a hardware fault with yours maybe something came disconnected in shipping.
For now, please can you try installing a new firmware using the firmware update tool in the app loader? https://banglejs.com/apps/?id=fwupdate - it should now work without you having to enter the bootloader mode.
If that works, awesome, your Bangle is all back to normal and working fine.
If it goes back to the LOCKUP loop you can get it working again by reflashing the firmware that you just did to get it going, but it would appear to be the sign of a hardware issue and I think it's best if we get you a new watch.
