Updating to Froyo 2.2 After Unrevoked Forever
Hey everyone, I have run Unrevoked Forever (after having already run Unrevoked 3). My question now is, what exactly do I need to do to be able to OTA update to Froyo now? My understanding is that I'll be able to always keep root after an OTA. I'm very grateful for this exploit from unrevoked, but the instructions on unrevoked wiki are just not clear enough for me. When (during just OTA or also if I flash it through clockwork) and why do I even need to flash a stock recovery? Anybody with a direct link to EVO stock recovery will be greatly appreciated as well.
Also, do I need to wipe if I upgrade to Froyo via OTA? Or is that just if I flash through recovery?
Here are the instructions given by the unrevoked team:
If you wish to install a stock over-the-air update in the future (OTA), the safest way to do so is to install the recovery that originally shipped with your phone. To install an OTA:
Install unrevoked forever on your phone.
Download or create an appropriate PB31IMG.ZIP or PC36IMG.ZIP for your phone that contains the original recovery image.
We do not supply these images; since the recovery code is owned by HTC, we don't distribute it. You may be able to find these images on the XDA-Developers forums.
From the phone operating system, install the over-the-air update.
When the update is done installing, you will probably want to root it with a custom recovery. Download one of the following recovery restore images:
Amon-Ra recovery for EVO 4G
ClockworkMod recovery for EVO 4G
ClockworkMod recovery for Incredible
Place the appropriate file – with that exact file name! – on the root of your SD card.
Reboot your device into HBOOT by removing the battery, pressing VOLUME DOWN, inserting the battery, and pressing POWER.
When prompted Do you want to start update?, press VOLUME UP for Yes. When prompted again Do you want to reboot device?, press VOLUME UP for Yes.
Your phone now has a custom recovery. To restore superuser access to your phone, you can apply any appropriate update.zip; such a file can likely be found on the XDA-Developers forums.

Ok thanks toast3d. I don't want to lost root, I guess I was confused. I was under the impression that after flashing unrevoked forever I would still have root even after an OTA. But the OTA didn't work for me anyway lol. I got some exclamation mark error.
