[Sony Ericsson XPERIA X10 Mini] Legendata:
My device keeps disconnecting. Windows 10 user. USB Selective suspend is disabled. Checked multiple usb cables. This is the log. If I can't flash the kernel could you offer me ROM which supports basic stuff like wifi, flashlight, messanger and mp3 player? Thank you.
