That didnt fix the issue :( but threw me in a new cyclce of spontanius reboots. Even in safe mode didnt change anything. Wifi would not turn on at all. To get out this I booted into the bootloader (hold down vol down during boot) and selected poweroff.
Now wifi starts and I am able to connect to my home network but after a couple of seconds I get disconnected again.
Is there a way for me to get more/better/more detailed logs? So far Ive been looking at the system logs setting but that tdoesnt have logs of previous boots.
Maybe a factory reset would fix this? But I dont really want to setup my phone again.
