[How To] Root DX2 2.3.5/1.3.418 magic md5 method

bhigham/beh and I have modified/combined a couple of root methods
based on New root method for stock 2.3.4 (621/622) found (Droid2, R2D2)

How this works
Originally Posted by phifcThere'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

5 options
a self extracting batch file
a regular batch file
slitaz boot img, (like ezSBF)
manual using adb/moto-fastboot
Voodoo method

I have tested and they work


basic instructions/steps for batch files and slitaz
first you need to be on 2.3.5/1.3.418
SBF and update.zip here Custom Droid X2 ROMs, SBFs, OTA updates
and moto drivers USB and PC Charging Drivers - Motorola Mobility, Inc. USA
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
for more details see manual adb/moto-fastboot option
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 installs bsr/system recovery


Root DX2 2.3.5 batch file in self extracting exe
DroidX2_Root_2012.exe

download
double click on DroidX2_Root_2012.exe to start
follow onscreen instructions

note: first reboot, goes to a nonlabeled fastboot mode, all you will see is moto boot logo dualcore screen just click enter to flash files

Root DX2 2.3.5 batch file
DX2_Batchroot.7z

download file
extract with 7zip
double click on rootdx2.bat to start
follow onscreen instructions

note: first reboot, goes to a nonlabeled fastboot mode, all you will see is moto boot logo dualcore screen
click enter to flash files


slitaz boot img, like ezSBF
Droid2_D2G_DX_DX2-RootCD-2012.iso

has options for D2, D2G, DX, and DX2
burn to cd with imgburn, or flash drive UNetBootin for Windows
restart pc boot to drive you mounted img to, cd drive or usb drive
some PCs will auto boot, some you need to press F8 or esc and select drive
follow onscreen instructions


manual method
may update this later

you need
moto-fastboot.exe not fastboot.exe in batch file
adb files found in petes root tools and batch file
Petes root tools
modified root.img in batch file

instructions
extract any .zip or .gz
move all files to same folder like C:\root to make it easier
Enable USB debugging on phone
open command prompt
enter
Code:
cd/
cd c:root
adb shell rm /data/preinstall_md5/magic.md5 ( don't worry if you see an error)
adb shell ln -s /data/local.prop /data/preinstall_md5/magic.md5
boot phone to fastboot (reboot, at moto logo, press volume down, when you see fastboot, press volume up to select)
run commands
Code:
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
Code:
adb shell
should give you a root prompt # (instead of $)

run petes root tools, zerg rush, or superoneclick
then you 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*, have altered/deleted stock file, or if you are already on 2.3.5/1.3.418 you have to SBF
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 , (Blur_Version.1.3.380.MB870.Verizon.en.US.zip)**
a via over the air or
b download, place in sd card root (not in a folder)
md5 B127D3AF93FD6A75C3A3D897C6D0FCD1
and install via stock recovery see Common X2 Questions and Answers

5 restore root with Voodoo

*zergrush may remove stock files, to root, causing update to fail
**updates are named by the version they are updating
md5 checksum windows / android
