I have problems with my e400. I installed CM9 yesterday. Since then the USB isn't working i.e. the PC doesn't recognize the phone and when I plug in the charger, it charges the battery but it doesn't show the process of charging. It's like I haven't plugged it. I had other issues with the software so I installed 2.4 again. The USB still doesn't work and now the phone is not ringing nor vibrating. It just shows that someone is calling. I checked the phone settings for both issues and everything is set up well.
I hope someone has a solution.. please!
