Root a T-Mobile G1 (HTC DREAM) and Install Cyanogenmod 6.0 (Android 2.2 Froyo)

So I spent about 5-6 hours a few days ago searching for a full tutorial of rooting a T-mobile G1 (HTC Dream) and then installing Android 2.2 Froyo on it (Cyanogenmod 6).

I could not find a full guide anywhere and I ended up using like 5 different sites and it was a huge headache! So I am creating a full tutorial here. This will have the latest radio and spl version.

I FOUND THIS TO BE THE EASIEST METHOD OF ROOTING A G1 AND INSTALLING A STABLE BUILD OF FROYO.
THIS IS DESIGNED FOR THE COMPLETE BEGINNER!!

I HAVE THIS ON MY G1 WITH NO PROBLEMS AT ALL!!!

**Please make sure your phone is completely charged before doing this**
**I am not responsible for anything that happens to your phone. Do this at your own risk**
---------------------------------------------------------------------------------------------
I was pretty worried about bricking my phone, but it is almost impossible if you do this step by step and correctly. Just make sure to follow the steps!
---------------------------------------------------------------------------------------------
Prerequisites:

**ALL DATA/APPLICATIONS WILL BE REMOVED FROM YOUR PHONE AND IT WILL BE RETURNED TO FACTORY SETTINGS AFTER THE FOLLOWING STEPS. MAKE SURE YOU HAVE SYNC SET UP FOR YOUR DATA SO THAT YOU CAN RECOVER YOUR CONTACTS!** (TO SYNC GO TO SETTING > DATA SYNChronization > make sure AUTO SYNC is checked as well as contacts calendar and gmail)

Here is what you will need:
1) Your Phone
2) A Computer
3) USB Cable
Download the following file onto your computer: (DO NOT UNZIP OR CHANGE ANY FILES!)
Original DREAIMG.nbh
Cupcake Update.zip

Amon Ra’s Recovery Image

G1 HardSPL
Generic G1 ROM w/ Root
CYANOGENMOD 6 ROM

I) Formatting the SD Card and Downgrading to RC29(YOU WILL DELETE EVERYTHING OFF YOUR SD CARD!)

1. Plug your USB cable into your computer and then plug your phone in.
2. Mount your SD card by sliding down the notification bar and selecting mount.
3. Go to My Computer and access your SD card.
4. BACKUP ANY FILES THAT YOU WANT ONTO YOUR COMPUTER. VERY IMPORTANT!
5. Go back to my computer and right click on the drive that is your sd card. Click format. Choose FAT32 from the drop down and hit the format button. This removes all data from your memory card.
6. Once the format is complete: drag and drop "DREAIMG.nbh & Update.zip files that you downloaded into the sd card. (DO NOT create a folder or anything, just put it right in the SD card)
7. Unmount your phone by going through the notification bar and then unplug your phone from your computer. Them turn off your phone.
8. Press and hold the camera+end key until until you see a screen with colored bars, then let go. This is the bootloader. The screen will turn gray with blue writing on it.
   
9. Hit the end key to start the update. DON'T DO ANYTHING UNTIL THIS IS DONE!
10. Once it is finished press the trackball to reboot. (If it goes back the the colored bar screen and doesn't reboot try holding the home+menu+end key, if this doesn't work, just remove the batter and put it back in and turn the phone on)
11. Once the phone is on, just turn it back off.
    
12. Now press the Home+End keys until you see a triangle with an exclamation point in it (this is recovery mode). Once you see this let go of the buttons.
    
13. Open the keyboard and press the ALT and L buttons, and then Press ALT and S buttons. Now wait until the phone reboots (it will do this automatically once the update is applied) (Don't worry if you see picture of a box and a g1 or a chip with an arrow)
14. Once the phone reboots, go ahead and and go through the welcome guide and get to the home screen.
