Root allows you to modify just about everything, flash new images,
change your boot image, change themes, run ARM debian, and tons more.
This guide goes through installing/downgrading to RC29, getting root, flashing the new recovery.img / test keys, changing the boot loader, and installing JesusFreke's modified RC33 builds.
If you're unsure about why you would want root, or aren't comfortable with flashing or poking around on your device, do not do this.
Update (3/10/09): Switched from RC30 to RC33 instructions, and clarified a few points.

more versions Available at NoOneHereYet's WebPage

And all of the great people over at
xda-developers and freenode/#android who make it all happen.
Let's get started.
Also, please
note that this will wipe out everything - all of your settings and apps - twice. By installing the RC29 nbh, you lose everything, and likewise moving to RC33 Or Cupcake_1.5.
There's 4 main files you're going to need:
In the following zip file : RC29NBH.zip is the DREAIMG.nbh you will need ...
Extract it from the zip ... and DO NOT RENAME IT !!!
DREAIMG.nbh
or...
DREAIMG.nbh
This is the NBH file needed to roll back to RC29 <<< this restores the security hole which allows root access..
recovery_testkeys.img The modified recovery image/test keys.
EngBootloader_v2_NoSigCheck.zip
The engineering bootloader. An update.zip.
It's recommended that you
read more about them here before choosing this one.

<<<=============================================== =>>>
Once you have all of the files, you're ready to go.
Once again, if you're unsure about why you would want root, or aren't comfortable with flashing or poking around on your device, do not do this.
It's definitely recommended that your phone's battery life remaining be full or near full when you start this, as it can take awhile depending on how quickly you do the steps.
Step 1)
- Format the Micro SD Card to FAT32.
- Copy the DREAIMG.nbh file to the Micro SD Card.
(NOT A ZIP FILE)
- With the phone off, hold camera and press power to boot into the bootloader.
- Once the bootloader is loaded, press power to install.
- Press the trackball to continue and press talk+menu+power to reboot.
Step 2)
BEFORE RUNNING THIS STEP: get the APPS
TELNET & TERMINAL From the AppMarket
- Copy recovery_testkeys.img onto the Micro SD Card.
- Turn the phone on (if not already)
- Type enter telnetd enter (this starts the server command_
- now go to you apps and start the App
Telnet
use the telnet application from the market and connect to localhost
OR
- Telnet into the phone with telnet (telnet ipaddress)
- Run the following as root (from within the Telnet app )
Code:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
dd if=/system/bin/sh of=/system/bin/su
chmod 4755 /system/bin/su
And you've created
su, a way to switch to the root user easily. Now we need to add the modified recovery test keys. Run the following in telnet again (or as root).
Code:
su
cd /system
cat /sdcard/recovery_testkeys.img > recovery.img
flash_image recovery recovery.img
Now that's finished.
Personally, I prefer to go with the Engineering bootloader, but you can
choose whichever you'd like.
Step 3)
- Rename whichever bootloader package you're going to use to update.zip
- Copy it onto the Micro SD Card.
- Turn off the phone (if not already,)
- Hold home+power to boot into recovery mode
- Alt+L to see the text
- Alt+S to install the bootloader
- When it's done, reboot
And now you've got the bootloader. Last but not least, if you'd like, you can install JesusFreke's RC33 builds that add a lot of extra goodness.
Step 4)
Note:
It's recommended elsewhere that you wipe your data (Alt+W in Recovery Mode) before applying this update. Although I don't do this myself, doing so never hurts.
- Rename to update.zip
- Copy it onto the Micro SD Card.
- Turn off the phone (if not already,)
- Hold home+power to boot into recovery mode
-
Alt+W to wipe the data, as noted above, if you so choose
.............. note Alt+W will remove all your downloaded apps ....
- Alt+L to see the text
- Alt+S to install the update
- When it's done, reboot (Home & Backkey)... (this is after you get the Recovery Menu the second time)
Step 5)
- Repeat the same process as in
Step 4 with the
RC33 or
Cupcake 1.5 Radio update. This update will restart your phone a few times and display the 'flashing rom' graphic, be patient, as it can take some time. And now you're done.
Easy as pie.
