Yes you can, I am not exactly sure on how to do it though, but I do know that after you run unrevoked you can move the RA PC36IMG.zip to you SD card then boot into hboot (power off then hold power+volume down until a white screen pops up) and it will search for an update then just tell it yes and it will install RA. When you move the file just make sure it is named exactly PC36IMG.zip.

 

I can't remember if you just use a regular PC36IMG or if you have to have it saved as a different file. I think if you go to Unrevokeds website they may have something about it in the FAQ.

 

Right, so what you need to do is get the RA img file. You can get it out of one of the PC36IMG.zip files, if you like, as they are just .img files, or you can get it directly from here. It's the exact same thing. In reflash_package, select the option for custom recovery, then select the img file. Honestly, it doesn't matter if you do it this way, or just flash RA later. Both are fairly easy. If you decide to do it after, you can use the PC36IMG.zip file or you can flash it through ROM manager (not sure if it's gotten the RA 2.3 update yet or not).

 

I just helped root my buddies EVO yesterday with unrevoked, just downloaded rom manager once rooted and chose flash alternate recovery, done and done
