[How To] Install Android 2.2 Froyo on HTC Desire

If you are one of the HTC Desire users who don't have the patience to wait until Q3 for an official Froyo build then you are in luck. udK_dev, a user from the xda-developer forums has managed to push out a near-perfect Android 2.2 port that works very well so far. The HTC Sense overlay is indeed included and while there are a few quirks here and there, most users who have tried it so far have thoroughly been pleased. The camera has even been upgraded to handle 720p video recording so that is a benefit as well. If you have some time on your hands and want to try it out OR if you really want to jump the bandwagon to Froyo early, check out the steps below:

How to flash DJDroid v1.0-R1 BETA:

The installation procedure of this Rom requires 2 steps:

1. Rom installation
2. Radio installation

Prerequisites:

• Rooted phone
• Koush Fakeflash installed on SD (see here)

Step 1 - Rom Installation

• a. Enter recovery (press volume down then - keeping it pressed - press power button) and make all the WIPES available, with the procedure you like the most.
• b. After WIPES have been done, use Fakeflash to install ROM file on your SD card.
  After installation procedure is over, reboot your phone (first reboot will take some time to complete, do nothing meanwhile).
  After first boot, complete first time phone configuration skipping all unnecessary steps (like network, accounts and the like - you will have time setup everything later on).
• Shut down the phone.

Step 2 - Radio Installation

• Switch on the phone entering recovery (again, volume down + power)
• Use fakeflash to make all wipes available, and when you are done, install file on sd card: RadioUpdate.zip. The install will be blazingly fast (less than 3 seconds).
• Using back button, go to main menu and reboot your phone.
  At this point, slowly and gently lean your phone on a flat surface (an altar would be an excellent choice) and start praying (it always helps...), while imagining our grinning faces......
  Your device will execute several operations, and reboot more than once.
  Do NEVER TOUCH it - NEVER.
  If you find yourself alone, riding in the green fields with the sun on your face, and you phone boots into Sense, do not be troubled. For you are in Elysium, and you're already done with the installation!
  On the other side, if you find yourself alone, and also twelve sexually aroused virgins appear around you, do not be troubled. For you didn't follow the procedure and your phone is already dead....
  At this point, you can follow the normal setup procedure as you wish.

P.S.:
A little gift: among the programs, you will find an app which can allow you to choose where to install your APKs!!! BIG thanks to JD82 for this APK!

Know issue:

• There are no wallpapers
• Some times the geolocalization could not work well
• It's possible that some times the device reboot for unknown reasons
