How to unroot from Skyraider 2.5.2

[gniss39#AC]

Hey fellow Android users, I tried to search on google for a solution to this but I could not find one for my specific needs. I rooted using Unrevoked and I have the 2.05 radio and Skyraider 2.5.2 with Froyo with no installed kernels.

I was wondering how I could unroot and go back to the stock DInc. I would like to do this so I can use Qazme's wonderful guide on how to update to 2.2 Froyo and have root, the easy way!

I tried downloading the PB31IMG.zip and put in on my SDcard (FAT32) that is ~139 mb but when I went into HBOOT it said "Main version is older! Update Fail!". Any ideas on how I can get back to stock 2.1 and the default 1.0 radio?

Thanks so much in advance and I apologize if I failed to find a thread explaining this process!

Why not just install Sky Raider RC3 which was built using the new release of 2.2.

That is one option. Is it as simple as downloading the zip file for SR RC3, putting it on my SD card and then selecting "Install ROM from SD card" using ROM manager on my phone?

You can down load it from ROM Manager or here here [ROM] SkyRaider Sense 3.0 RC3 a2ext/a2emmc/EspressoMod/NewButtons [UPDATED: 08/29/10] - xda-developers then install from ROM Manager or in recovery.
