Released on Wednesday, the new software update for the HTC Touch HD was supposed to improve the on-screen slider feature for answering calls. Many of the Touch HD users (including me) has got another problem caused by the hot fix. Right after the installation, the phone dialer has a strange layer “Call Hi…” (Call History?) on top of the video call button and video calls could not be made without access to the button.

To fix the problem, you can’t simply uninstall the hot fix as it will not revert back your old system files. Cool dude from xda-developers has created a simple solution, which allow you to undo the hot fix and get back the old system files. Check the instruction here

The method works, although you might still need the buggy fix if you are facing problem with the answering call slider.
