My phone: LG E400
rom: SDmerge+ miniCM (not sure if the problem is connected with that as everything was fine at the beginning)
All of a sudden my phone didn't show usb connection any more. No connection is shown in the phone or PC, but the phone is charging.
I tried all usb connection options, usb debugging on/off, no result.
Uninstalled all phone drivers in my PC and reinstalled LG driver, nothing.
Tried another usb cable and another PC, the same problem.
Also tried turning off my phone while connected, no help.
Please help me.
Don't know if it helps but I once saw a strange message in Titanium backup while usb was connected (this was after the problem started, so no usb connection was shown, usb debugging was on). It only happened once, so I'm not 100% sure what it said but it was sth about that I should turn on usb debugging.
