Hi everyone. I'm new here and new to HTC/ android phones. I recently tried upgrading my htc inapire 4G to the newest software At&T has. Essentially I followed all the steps but when the installation was finished the phone just wouldn't go past the White screen. I av tried battery pull numerous times. Have even tried recovery, factory reset, wipe cache but nothing seems to work. Whenever I choose the recovery option a green circular arrws comes on the phone screen but is quickly replaced by a phone icon with a red triangle next to it. I really don't know what next n i'm frustrated. Anyone knows what the symbol means or how to fix the situation. Any advice/ suggestions are welcome. Thanks.
