I flashed PE4.2 and now I have major problems. I did all the usual, wipe, format, etc. I have flashed roms for 6 months and never had these problems. My apps will not download from the market. When I try to clear the cache, the app mgr says computing and will not let me. I get a lot of system FC's. TB will not restore my backups. It just "thinks" but will not perform the function. I have flashed a backup but the problems still exist. When I go to manage apps and press sd card, nothing shows up. I pulled the card and inserted it in my computer and I can access the contents. I went into recovery in partitions menu and mounted sd card but still unable to connect. When I try to usb connect to the computer, it will recognize the phone but the phone will not communicate with the computer even though all the drivers are there. I found I can restore all system info from TB but not any apps. Someone please help. Edit: I think my problems started when I used hot boot. I get an error msg "Process system is not responding". I have to do a battery pull to reboot.
