As our regular readers will tell you, we’ve been following the HTC EVO 3D closely. Not too long ago, it received an ICS leak and its associated problems. The leak wasn’t for the Sprint or GSM versions of the phone, but rather for the Virgin Mobile version of the phone, which hasn’t even been released yet. As you can imagine, early adopters who flashed the red hot leak had some serious problems—not least of which was being unable to revert back to factory firmware. Fortunately, those days have come to an end.
XDA Senior Member jlechner, with the help of other developers, has released a full method to downgrade the EVO 3D back to its Gingerbread roots. The process is a little complicated, and requires that users know how to flash RUU files in the bootloader as well as ADB commands, so this is definitely not for the faint of heart. Jlechner is kind enough to provide links for all downloads you’ll need. The whole process will take roughly half an hour once everything is in place. However, there is also a stern warning:
This works for some, others are having data issues after. YMMV.
WARNING: Some can’t activate now. Your risk.
So if you’re not confident your device can handle the return to Gingerbread, it’s probably best to skip this for right now. If you really want to revert to the older firmware, you do so at your own risk.
