[myTouch 3G, Magic Android Development] AntonJart:
This tutorial was written specifically for T-Mobile MyTouch 3G 32B. It will ruin your device if you flash it elsewhere rather than on 32B MyTouch 3G. This thread is no longer supported because: 1. I do not remember anything about MyTouch 3G anymore; and 2. I do not have it anymore.

Also files could be corrupt after two years no one payed attention to them. So everything you do from this thread is solely on your own risk!

Hello everyone. I'm creating this thread because there are many noobs, just like myself, who ask too many questions and fail to use search properly. I just want to make it easier for dummies to find and do this, I take no credit for the work below mentioned people have done. I want to say thank you to those who made this all possible.

CLShortFuse for making super easy Rooting method. Original topic.

Amon_RA for making custom recovery for all of us. RA recovery thread

dasunsrule32 for making easy step by step tutorial. Original thread

xillius200 for providing flashable zips and guide. Original thread

Ohsaka and ezterry for amazing superwipe. Original thread

This is for MyTouch 3G 32B original (No Fender, 3.5 mm jack)

You will be flashing:

Radio: 2.22.27.08

SPL: 1.33.0013d

1. Your device should be rooted if you want to do it. SuperOneClick should work like a charm. Could be found here.

2. Download recovery and install it if you didn't do it yet. It could be performed by using Clockwork's app from the market. You can also use Clockwork's recovery if you want.

Note: The new OTA 2.2.1 update is going to restore original recovery after each boot, and will delete the custom one. (This happened to me) I tried flashing ROM before it was deleted and got Boot loops, no matter what ROM I used. Boot loop is when your phone got stuck on the green "MyTouch" image and restarts in circles. This is my way of doing it because I was a noob and found it longer but easy. Search through the thread, some of the users described that it is not necessary to downgrade. What helped me was flashing Android 1.5, then updating it to 1.6, and from there installing custom ROM. It worked for me, I'm not sure it will work for everyone. dasunsrule32 says you need custom SPL for doing it, but it worked for me without one.

Tutorial is here, chose section

DOWNGRADE TO DONUT OTA:

3. Download flashable zips (radio and hboot) from xillius200 post (here) and download Ohsaka's superwipe here

4. Put Radio, hboot, and superwipe zip files into root directory of your SD card.

5. Make a nandroid back up (through recovery). And do Titanium back up of your apps and data, read the note:

Note: your current ROM might not be working with new radio and SPL, as mine OTA Rom did not work. I had to flash specific one. So make sure you backed up your apps and data. Titanium backup from Market should work fine.

6. Download ROM that you will be using. Make sure it works with the SPL and Radio you will be changing.

7. Make sure you have done step 4. Go into recovery and chose "install zip" and pick superwipe. Wait for it to finish and Chose "Power OFF." and then boot up into recovery.

8. Now you are good to flash Radio. Chose "Flash Zip" and pick radio and flash it. Your phone should reboot, I think mine didn't so I had to do it manually.

9. Boot into recovery again and now flash hboot zip file. Your phone should reboot after flashing.

10. Now you should be done and can flash the ROM. You can check your radio and SPL by booting your phone by pressing Volume Down and Power buttons at the same time.

PS: I take no responsibility if you brick your device.
