How to safely downgrade to Gingerbread after accepting Honeycomb OTA on HTC EVO View 4G
Previously, we showed you how to accept the official OTA Honeycomb update on your rooted HTC EVO View 4G that had the S-OFF hboot supplied by Revolutionary. (Before that, we showed you how to unbrick your View if you were rooted and unsuccessfully attempted to apply this update.) But what if you have never rooted your tablet, took the update, and are now kicking yourself for doing so?
There are certainly plenty of reasons to want to downgrade: for example, not all apps that were compatible with Gingerbread are compatible with Honeycomb. You also loose the hardware buttons, and there is certainly a slight learning curve with Honeycomb if you've never used it before. (This video showcases some main differences if you haven't upgraded yet.)
Luckily, developer globatron has come up with a way to downgrade back to Gingerbread if you regret taking the Honeycomb update. However, keep in mind that this method is for unrooted, S-ON View owners only. This method also involves unlocking your device using HTC's official bootloader unlock tool, which might turn some people off right away. Additionally, it requires some level of comfort with ADB and command prompts, so if you do not consider yourself an advanced user, you might not want to try this yourself.
But if you're dying to go back to Gingerbread, check out the instructions at the link below, and good luck.[xda-developers]
