My HTC Sensation wifi stopped some time ago, the phone was rooted when I picked it up 2nd hand, and I had no knowledge of how to fix it except reboot the device which fixed nothing. The Bluetooth stopped working soon after, so I took it to a tech friend who was able to re-install the stock os, but the wifi still does not work (says "error"). The Bluetooth is back, it can connect to devices, but I get audio only, microphone is not working, Help! Rebooting has not resolved the issues. I read somewhere that the upgrade to ICS os is the culprit. Can someone in the know please tell me what the problem is or suggest any ideas on how to fix this? Thank you!
