Hi,

I thought I had messed with my OS, so I needed to flash the phone. I flashed it already ~12 times in the last 2 days, but following situation still occurs.
  • When I want to connect to the internet and open the dialog, spontaneously after an uncertain amount of time that could be 5 minutes, the list of networks is shown, just to disappear soon again after a few seconds. When trying to connect it fails "There is something wrong with the network connection".
  • alternatively, the phone just restarts when it opens the network list dialog.
  • in rare instances the network connection can be established, just to lose the connection soon or reboot.

please, how can I check wether the wifi module is broken? I still hope there is something else wrong, e.g. error in the flashed image (unlikely, I used it successfully already about 5 times)

Sounds very much like a hardware issue.
Could be bad flash memory, bad wifi chip, or, perhaps some wire got bad connection inside.
