I tried to flash firmware in DFU mode but even there it can not be found by the nRF or DFU android apps.
Hmm, that's definitely a bit concerning. With the original Bangle.js 2 KickStarter Bangles we did have a few where Bluetooth failed because of a bad joint on the PCB, but I thought that all the ones that were going to fail had already failed.
One way to know for sure is to put it in DFU mode, and then pinch the top right corner (pressing the screen and back together) and see if while you're pressing you can scan for it on BLE
