STEP 1: DOWNGRADE

Our first step is going to downgrade your phone to RC29, This is like removing Windows XP Service Pack 3 and installing Windows XP Service Pack 1. It allows us to use a security flaw to gain root access. This section is going to use FILE 1 from the downloads

3) You should see a gray/white screen with instructions to flash your phone with the update on your SD card.

4) As per the on-screen instructions, press the Power button to start upgrade procedure. DO NOT INTERRUPT THIS PROCESS.

5) After it is finished, perform the restart your phone. (May take up to 15 minutes to boot)

6) Complete the setup process for gmail.

STEP 2: ROOT

Your phone is now downgraded and we can use the security flaw to replace the recovery image. The "recovery" is kinda like a boot disk on your computer, we use this to delete, modify, and create system files while they are not in use my the ROM. The recovery will be used when ever you flash pretty much anything to your phone.This section is going to use FILE 2 from the downloads

1) At the home screen hit the enter key twice, type "telnetd" and press enter. IGNORE WHAT THE SCREEN IS DOING

2) Press Home

3) Goto the market and download "Telnet"

4) Open Telnet and connect to localhost : 23

5) Press enter and you should see a #

6) Now type the following and press enter at the end of each line

mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system

cd sdcard

flash_image recovery cm-recovery-1.4.img

cat cm-recovery-1.4.img > /system/recovery.img

7) Press the home button

STEP 3: HardSPL

Now we are going to change the bootloader or "SPL". Currently your SPL will only allow you to flash ROMs that HTC or your carrier have produced. This new "HardSPL" will allow us to flash ANY ROM we want. This section is going to use FILE 3 from the downloads

1) Hold power and turn the phone off

2) Start up in recovery mode by holding home and pressing power.

3) You will now enter recovery mode.

4) Press Alt-S to apply the update.zip from the SD card. This is the spl you downloaded.

5) After the update is complete, hold Home and press Back to restart. (May take up to 15 minutes to boot)

STEP 4: ROM

Now we are going to flash the latest ROM from Cyanogen. This is your new "Operating System". This section is going to use FILE 4 and FILE 5 from the downloads

1) Hold power and turn the phone off

2) Start up in recovery mode by holding home and pressing power.

3) You are now in recovery mode.

8) You will be returned to the recovery screen in a few minutes, be patient.

9) Press Alt-A to apply any zip from sd

10) Choose update-cm-4.2.1-signed.zip

11) After the update is complete, hold Home and press Back to restart. (May take up to 15 minutes to boot)

You can NOT run HERO ROMs YET!!!!!!!
