Regain root after running leaked 2.1 RUU

[bradart]

Jacked straight from GBhil on androidcentral:

1. Make sure you have the Android SDK installed. Read HERE for more info.

2. Download 4shared.com - online file sharing and storage - download flash_image.zip

3. Download 4shared.com - online file sharing and storage - download recovery-RA-heroc-v1.5.2.img

4. Unzip the first file, and place both in your Android SDK/tools folder.

5. Make sure USB debugging is ON

6. Connect your phone to the PC

7. Open the command window and navigate to the Android-sdk/tools folder on your computer.

8. At the prompt enter the following, one line at a time followed by enter
Code:
adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
exit
exit
adb push flash_image /system/bin
adb push recovery-RA-heroc-v1.5.2.img /sdcard
adb shell
chmod 0755 /system/bin/flash_image
reboot
9. Your phone will reboot. When it is finished, back at your command window, once again enter
Code:
adb shell
su
cd /sdcard
flash_image recovery recovery-RA-heroc-v1.5.2.img
reboot recovery
10. With any luck, you'll have the recovery image back and can load custom 2.1 based ROMS again.

Tested and confirmed by GBhil himself. I have not tried this, but if you're stuck, it can't hurt to try. Mods, please sticky if you desire.
