based on New root method for stock 2.3.4 (621/622) found (Droid2, R2D2)
How this works
Quote
There's an exploit in loadpreinstall.sh. It compares md5 sum files of preinstalled apps and if they're different, copies the md5 to the local cache. The preinstall just has an empty file in app/ so it will parse the md5 for it. Instead of an md5 sum, it contains a local.prop that allows adb root shell. So the system thinks it's copying the md5sum to the cache when it bounces off the symlink and overwrites the /data/local.prop, giving adb root on next reboot

have 5 options
a self extracting batch file
a regular batch file
slitaz boot cd, (like ezSBF)
manual adb/moto-fastboot
Voodoo method
I have tested and they work
basic instructions/steps for batch files and slitaz
you need to be on 2.3.5/1.3.418
SBF and update.zip here http://forum.xda-dev.....php?t=1703640
and Motorola Drivers need to be installed
turn phone on
enable usb debugging (system/apps/developer options)
connect to pc
change usb mode to charge only or pc mode
start program, see instructions specified with the option you chose
there are on screen instruction, but this is what will happen
a file is pushed to your phone with adb
phone will reboot to fastboot, all you will see on phone is moto boot logo dualcore screen
click enter
two files will be flashed to phone
phone will reboot
when it has completed reboot
click enter
phone will reboot
when phone has completed reboot
click enter
files will be pushed to phone with adb
phone will reboot
when phone has completed reboot
click enter
files will be pushed to phone with adb
phone will reboot to recovery
press both volume buttons when you see ! in a triangle with android andy
wipe cache using volume buttons to scroll, select with power button
when complete, select reboot with power button
Done.
when running the batch file or slitaz you may see these errors
rm failed for /data/preinstall_md5/magic.md5 no such file or directory
no root.img.gz no such file or directory
rm failed for /data/preinstall_md5/magic.md5 read only file system
that is fine, it will still work
and it should installs bsr/ system recovery
Root DX2 2.3.5 batch file in self extracting exe
DroidX2_Root_2012.exe

has options for D2, D2G, DX, and DX2
burn to cd with imgburn, or flash drive use Download UNetBootin for Windows
Manual method may update this later
you need
moto-fastboot.exe not fastboot.exe
adb files found in petes root tools
Petes root tools
modified root.img
instructions
extract any .zip or .gz
move all files to same folder like C:\root to make it easy
Enable USB debugging on phone
open command prompt
enter
cd/ cd c:root adb shell rm /data/preinstall_md5/magic.md5 adb shell ln -s /data/local.prop /data/preinstall_md5/magic.md5( don't worry if you see an error)
boot phone to fastboot
run commands
moto-fastboot.exe flash preinstall root.img moto-fastboot.exe reboot
let phone boot complete, then reboot again (reboot just replaces the local.prop, but the old local.prop is still in memory, till second reboot)
command
adb shellshould give you a root prompt (# instead of $)
run petes root tools, zerg rush, or superoneclick
then you are rooted
voodoo method
1 start with full stock 2.3.4/1.3.380,if you have rooted with anything other than Pete’s Root Tools
or have altered/deleted stock file you need to
SBF to full stock 2.3.4/1.3.380 (VRZ_MB870_4.5.1A-DTN-150-30_1FF_01.sbf)
read How to SBF an X2, ezSBF DX2, and Common X2 Questions and Answers
if you don't want to lose data, don't wipe data (although it is recommended), unless you bootloop
if you bootloop you have no choice, but to wipe data via stock recovery see Common X2 Questions and Answers
2 Root with Pete's Root Tools
3 install Voodoo OTA Root Keeper, backup su, then temp unroot (keeps backup)
4 install update 2.3.5/1.3.418 , via over the air or download, place in sd card root (not in a folder)
and install via stock recovery see Common X2 Questions and Answers
5 restore root with Voodoo
edit:
zergrush removes stock files, to root, causing update to fail
