Today we gave you a brief step by step on how to root T-Mobile Samsung Galaxy S II and HTC Amaze 4G which allows you to install root-only apps such as Titanium Backup. Now great news has come for HTC Desire HD users because an XDA Developer viperbjk has managed to S-OFF, root, and flash a custom ROM on your Desire HD handset.
