Ok. First of all this happened to me three times already and it "fixed itself" after a full drain/recharge this is the fourth and for some reason nothing is working to fix it.
It happens when my phone crashes and I have to take the battery out, when I put the battery back on and turn it on again this is what happens:
-when booting the HTC logo shows for 5-20 min until the cm7 bootscreen shows.
-touchscreen is not working
-calling/music/contacts is not working(although sms works fine)
-the orientation sensor got totally broken the first time it happened, its still not working even when the rest worked.
I tried flashing several roms, draining the battery and recharging it, even restarting it multiple times till the battery drains.|

Can anyone please help me?? I'm 16 and I don't have the cash to have it fixed or buy a new phone.
and thanks in advance for those who will reply.
