Hey guys, just wanted to share my experience modding my G1. This really sped up my G1 running on CM. BEWARE! If you are a heavy 3d gamer on your phone, the following is NOT recommended. Otherwise, let's roll!

Also, I must state that My Cellular Source and I can NOT be held responsible if you brick your phone. Do this at your own risk.

What you need:
-Root access
-Cyanogenmod ROM
-Terminal Emulator (included in CM ROM)
-Boot img for current CM ROM running on your phone

If you're running the latest G1 or Magic ROM, which is 4.2.14.1, get the boot img here

If you're NOT running the latest version of CM and are running a previous version.. UPDATE! What are you waiting for?!

Download the boot img, place it in the root level (top level, not in any folders) of your SD card

Run Terminal Emulator

Type the following (words in parentheses are not to be typed. They are actions. Also, there will always be a # sign in front of what you type):

su(press enter)(click always allow if screen shows up)

flash_image(space)boot(space)/sdcard/boot42141.img(press enter)

reboot(enter)

Wait for the device to load, and voila. 10 more mb of PHYSICAL RAM. You will notice a nice boost in speed. This is accomplished by sharing video memory with the GPU as RAM. So as I said, if you're heavy on the 3d gaming, this is NOT for you.

Don't let the disclaimer scare you It's a mighty fine increase in speed and is completely reversible! Contact me for any questions. Special thanks to the guys at Absolutely Android.
