How to restore stock ROM on HTC HD2? How to remove everything that I installed for Android or Windows Phone 7? I need to send HTC HD2 to HTC Support for warranty service because unlocking bootloader may void all or parts of your warranty. No worry, you can restore HTC HD2 to stock ROM and everything back to stock even after installed Android or Windows Phone 7. Just follow below step by step video guide.
Note – make sure that you have downloaded a HTC HD2 official Windows Mobile ROM from HTC Website for your country. Don’t use other region ROM other than your very own region. As for T-Mobile HD2, do download yours from T-Mobile website. And use free unzip software – 7-Zip to extract the exe file.
