[myTouch 4G Android Development] Phateless:
THIS THREAD IS ONLY FOR MYTOUCH 4G AND OBSOLETE ANYWAY. The official version of 3.0.2.4 can be flashed via rom manager with no mods except basic permroot.

The purpose of this post is to increase the visibility of these instructions so the CM7 threads don't get cluttered with this question being asked again and again. Mods feel free to move wherever you like. This is NOT my method, I'm merely regurgitating information that I learned by READING and SEARCHING! *Ahem!* :p

As I understand it CWR (ClockWork Recovery) 2 is needed for CM6 and CWR3 is needed for CM7. I don't believe there is much (if any) reverse compatibility at this time. I'm sure that will change in the future.

METHOD 1 - TrueBlue_Drew's ROM Manager swap - EASIEST

REQUIRED - S-OFF, ROOT ACCESS and ClockworkMod Recovery already installed.

If you don't yet have CW Recovery, install Rom Manager from the Market and use it to flash Clockwork Recovery.

METHOD 2 - Fastboot - Cleanest but slightly more advanced

REQUIRED - S-OFF, Android SDK (ADB) installed and some basic knowledge of how to navigate a windows command prompt. If you don't have the SDK set up yet a simple search will get you a few guides on how to do it. Not very difficult at all, don't worry.

1. Download CWR3. - http://phones.crackflashers.com/glacier/recoveries/glacier-cwm3src-2.img

2. Save to your Android SDK tools (c:\android-sdk-windows\tools) or platform-tools (c:\android-sdk-windows\platform-tools) folder and rename to recovery.img

3. Turn off your phone.

4. Hold the volume down button + power until you boot to a white screen.

5. Use the volume rocker to select FASTBOOT then press the power button to select it.

6. Connect your phone.

7. Open up a windows command prompt and navigate to your sdk tools or platform tools folder. tools (c:\android-sdk-windows\tools) or platform-tools (c:\android-sdk-windows\platform-tools)

8. Type FASTBOOT DEVICES to make sure your computer "sees" your phone and is ready to flash the recovery. You should get a serial number and then the word fastboot as the output.

9. Type fastboot flash recovery recovery.img and press enter. Give it a minute to do it's thing. You should get a message that says writing recovery and success.

10. Unplug your phone and use the volume rocker to select BOOTLOADER and then again to select RECOVERY and you should be booted into the orange menu of Clockwork Recovery 3.

11. Enjoy flashing CM7! :)

METHOD 3 - Terminal Emulator - less set-up required than method 2

REQUIRED - ROOT ACCESS, flash_image binary. Some ROMs (CM6) have the flash_image binary and some ROMs (Stock Sense and Iced Glacier) don't. There is a link below.

1. Download CWR3. - http://phones.crackflashers.com/glacier/recoveries/glacier-cwm3src-2.img

2. Rename to recovery.img and put on root of sdcard.

3. Download the flash_image binary to your sdcard. - http://www.filefactory.com/file/ce1cc72/n/flash_image

4. Use Root Explorer (or adb push if you prefer) to copy flash_image to system/bin. LEAVE FILE WITHOUT AN EXTENSION.

--4a. If you don't have Root Explorer and aren't familiar with adb, see THIS GUIDE to add flash_image via Terminal Emulator. http://xdaforums.com/showthread.php?p=10795540#post10795540

5. Open Terminal Emulator and type flash_image recovery sdcard/recovery.img

6. You're done! Go flash CM7 and enjoy! :)

If you want to go back to Clockwork Recovery 2 and CM6 or Sense, just use Rom Manger to flash recovery and proceed as normal. If you've found this post helpful, please link it to others and repost it! We were all noobs once, especially me. :D
