This How-to assumes you know how to use the basic functions of your phone. And that you can follow directions!
*Update*
Note with unRevoked 3.2 you can now root the OTA Froyo, which give you this same thing without all the hassle!
UnRevoked 3.1 at this time does not give you the ability to root Froyo. So you have two choices. Install the update.zip, flash clockworkmod, and install a rooted ROM which totally wastes your time as you are working in a circle. Or do it the simple way!
While still on 2.1 follow these directions, this is assuming you don't have root or anything, just a working phone.
1. Uninstall HTC Sync if you have it on your computer.
2. Download and install unRevoked 3.1 and root your phone.
4. Your phone will now reboot into recovery. This is called clockworkmod. Black screen with green writing.
5. BEFORE DOING ANYTHING, make a nandroid backup. This can be done in the backup/restore menu.
Now before you can go to Froyo you need to have a 2.x radio, I suggest the 2.15 radio. To do this you will need to s-off your phone with unRevoked Forever. So reboot your phone into Sense we need to take care of that.
5. Download unRevoked Forever.
6. Mount your phone as a disk drive.
7. Place the "unreokved-forever.zip" onto your SD card.
8. Reboot your phone into recovery.
Once it tells you the installation has completed, reboot your phone. Now we have a rooted 2.1 with the s-off mod!! Not so bad was it? Now for Froyo. Like I said previously you need to have a 2.x radio, I preferr the 2.15 radio and it's the one that comes with the offical update.
11. Download the PB31IMG.zip file that contains the 2.15 radio.
12. Place it into the root of your SD card. (If you are still in recovery just 'mount usb storage' and it will pop up on your computer.)
13. Reboot into hboot. Volume down + power.
14. You will notice a blue bar pop up on the right hand side of the screen. This is hboot reading the PB31IMG.zip file.
15. Once it complete in red letters it will ask you if you want to install press volume up. Press volume up.
16. Wait till it completes DO NOT PULL YOU BATTERY AT ANY TIME DURING THIS PROCESS!!!!!
17. Once it complete it will ask you if you want to reboot your phone press volume up. So press volume up already!
18. This boot will take a little while. Give it up to 20 minutes to boot (should take about 5-10 minute MAX). If it doesn't boot and stays at the HTC Incredible screen pull the battery and reboot.
Now you should be booted up into Sense UI once again. Your phone is now rooted 2.1, s-off'd, and should have the 2.15 radio. But first we want to make sure!
19. Menu --> Settings --> About Phone --> Software Information --> Under Baseband Version it should say 2.15.00.07.28. You are now ready for Froyo!!!! BUT before you go another step, mount your phone as a disk drive and delete the PB31IMG.zip file from the SD card. This will help prevent us from installing this radio twice and bricking your phone!
So now lets get cracking on Froyo. It has been confirmed the ROM pulled from the RUU matches md5's with the OTA. So go to this link and download one of the ROMs. You have two options "Unmodified, Odexed Version" and the "Deodexed Version". What's the difference!?
Odexed means it is signature checked, meaning no theming etc. This is the closest to OTA as you will get with root. De-odexed means you can theme it and change system files, you know the fun stuff!
20. Place the file you download, it will be a zip file, onto the root of your SD card.
21. Before we go any further you will want ROM Manager from the market, find it install it, it will make your life much easier from this point on.
22. Once you have ROM Manager installed open it. It will ask for superuser permissions so grant it.
23. Click on the "Problems?" button and allow it to download a busybox version.
24. On the top of ROM Manager you will see your clockwork recovery version. Click it to update to the newest version of clockwork mod.
25. Now for the fun part! Click install rom from SD card.
26. Select the ROM your copied over.
27. Select "Wipe cache / data" and if you haven't made a backup yet select make a backup.
28. Let it do it's thing. It will now reboot you into recovery, do everything you asked it to do, including installing the 2.2 ROM.
This first boot will take a little bit so give it time. Once your phone boots up, you have a rooted, s-off', fully working Froyo install! Enjoy your icecream!
