I'm currently rooted (Easy Root) on a stock ROM D1 (2.2 FRG01B) and I receivced an OTA update this morning - most likely FRG22D. I've made a nandroid back up and a ROM backup before I made any changes. So far, I've only removed some of the bloatware from the stock ROM - 5 or 6 programs. Do I unroot, install the update and reroot? Is it that easy? Or do I have to install one of the backups?
