PLEASE READ!!!!!!! Before proceeding, you need to
find out which hboot your device has and if your device is S-ON or
S-OFF. Ensure that Settings>Power>Fast Boot is unchecked and power
down your device. Once your device is powered down, hold Power+Volume
Down until you reach the bootloader screen.
On the second line, it should say "DOUBLESHOT PVT SHIP S-ON" or
"DOUBLESHOT PVT SHIP S-OFF." If you are already S-OFF, great! You can
flash a custom recovery in step 5 of this guide (although you need to
have
ADB/Fastboot installed on your Windows PC).
Your device is most likely S-ON. If so, continue reading. On the third
line, your hboot information should be listed. If you have
HBOOT-1.45.0013, you have the newer hboot and can follow this entire
guide to achieve root. Most newer devices have HBOOT-1.45.0013.
If by chance you have the older HBOOT-1.44.0007, you have two options for rooting your device:
1. Use
Revolutionary.io to gain S-OFF on your device. After using Revolutionary to achieve S-OFF, you can
install adb/fastboot on your computer (in case you haven't done so already) and continue from step 5 of this guide to flash a custom recovery and Superuser for root,
OR
2. Update to latest OTA release and use this guide from beginning to
end. You can update to the latest OTA release by going to
Settings>About Phone or by using
Blue6IX’s post “How-To: Restore to Stock.” Either method will update you to the latest OTA release (1.63.531.2) and HBOOT-1.45.0013.
IMPORTANT NOTE: If you update to latest OTA release with
HBOOT-1.45.0013, you will NOT be able to revert back to the older hboot
and S-OFF unless you use JuopunutBear to S-OFF. This involves a "wire
trick" that some people are not comfortable with.
Many users have successfully achieved S-OFF with JuopunutBear (including
me), but others have reported that it bricked their phone. This is
usually because they do not follow the directions that say not to touch
the bare wire. Check out the JB S-OFF threads
here and
here for other users’ experiences.
Confused about S-ON vs S-OFF?
S-ON, Revolutionary S-OFF, and JuopunutBear S-OFF are described in detail here.
Revolutionary S-OFF is for HBOOT-1.44.0007. JuopunutBear S-OFF is for HBOOT-1.45.0013. Got it? Good.

This is a step-by-step guide for rooting the MT4GS, designed
specifically for new users (aka NOOBS), by a noob. The process is
slightly more complicated than rooting other devices (i.e. Samsung), but
it is well worth it.
The MT4GS is one of the best qwerty phones on the market and has some of
the best developers. Don’t let the process discourage or intimidate
you. Just FOLLOW EACH STEP IN SEQUENTIAL ORDER and you’ll be fine.
Here’s a breakdown of the process:
1. INSTALL HTC DRIVERS ON YOUR PC.
2. INSTALL ADB AND FASTBOOT ON YOUR PC.
3. REGISTER AT HTC DEV.
4. UNLOCK BOOTLOADER THROUGH HTC DEV.
5. INSTALL A CUSTOM RECOVERY.
6. ROOT YOUR DEVICE.
7. USE JUOPUNUTBEAR TO GAIN S-OFF (OPTIONAL).
-PREREQUISITES-
Before getting started, please visit the
MT4GS Compendium and read over Section One to learn the XDA Lingo. You really need to know this stuff if you’re going to tinker with the MT4GS.
Also, all information in the guide assumes you are using a Windows PC
and a MT4GS with the STOCK ROM AND HBOOT-1.45.0013. If you are not on
the Stock ROM, please use
Blue6IX’s post “How-To: Restore to Stock.” Be sure to use the latest OTA (1.63.531.2). Once you're all set, let’s begin, shall we?
Disclaimer: I am not responsible for anything that happens to your
phone. You assume all risks associated with modifying your phone.
-1. INSTALL HTC DRIVERS ON YOUR PC.-
Install the HTC Drivers on your PC
from here.
Before connecting your phone, make sure USB Debugging is enabled (Settings>Applications>Development>USB Debugging).
Tip: to save time later, turn off your phone, hold down Power &
Volume Down simultaneously until you reach the bootloader. Use the
volume buttons to navigate to FASTBOOT and select it with the power
button. Connect your phone via USB and the bootloader should now say
FASTBOOT USB mode. Allow your PC to install the required drivers
automatically. It may take a few minutes for your PC to search for and
install drivers, so be patient.
-2. INSTALL ADB AND FASTBOOT ON YOUR PC.-
Installing ADB and fastboot on your PC is easy.
Follow this guide and you’re good to go.
To confirm that you have successfully installed ADB and fastboot,
connect phone (with USB Debugging enabled) to PC via USB, open command
prompt, and type “adb devices”. Your device ID number should be listed.
Here are some useful commands for ADB and fastboot.
-3. REGISTER AT HTC DEV.-
Self-explanatory. Visit
HTCDev.com
and sign up with a valid e-mail address, as you’ll be receiving your
Unlock_code.bin from HTC through this e-mail. Use an alternate browser
such as IE, Google Chrome, or Mozilla Firefox if HTC Dev doesn’t play
nice with your current browser of choice. Personally, I had to switch
between Chrome and Firefox to get the HTC Dev website to cooperate.
-4. UNLOCK BOOTLOADER THROUGH HTC DEV.-
Make sure you’re logged in to
HTC Dev
and follow on-screen instructions to unlock bootloader. FYI, our device
is listed as “myTouch 4G Slide (T-Mobile US)”. You can skip HTC’s
instructions until step 5 since they're just telling you how to install
ADB and fastboot, but you should already have ADB and fastboot installed
.
After you finish unlocking the bootloader, the first line in your bootloader should read “*** UNLOCKED ***”.
-5. INSTALL A CUSTOM RECOVERY.-
Download official ClockworkMod Recovery 5.0.2.7 from the
ROM Manager
website or download another custom recovery from the MT4GS Development
section. For instruction purposes, I will assume that you use official
CWM Recovery 5.0.2.7. Save the img file to C:\.
Put your phone in bootloader FASTBOOT mode and connect to PC. Go to
command prompt on PC and type “fastboot devices”. Once your device ID is
listed, type “cd\” to get to “C:\” directory. Then type “fastboot flash
recovery recovery-clockwork-5.0.2.7-doubleshot.img”.
After fastboot finishes, disconnect your MT4GS, go into bootloader, and
go to “RECOVERY.” You should now be in ClockworkMod Recovery 5.0.2.7.
The first thing I would do in CWM Recovery is make a backup of your
stock ROM for safe keeping.
NOTE: Use volume buttons or trackpad to navigate through CWM Recovery
5.0.2.7. Select items by pressing the trackball. Power button may make
your screen go blank and Back button returns you to the previous menu.
-6. ROOT YOUR DEVICE.-
Now that you have a custom recovery, you can flash custom ROMs. These
custom ROMs are already rooted with Superuser and binary files.
NOTE: If you are S-ON, installing a custom ICS ROM will require an extra
step in fastboot. You will have to extract the “boot.img” from the ROM
and flash it with fastboot after installing the ROM in CWM recovery.
More information from Limewirelord.
HOWEVER, if you want to root the STOCK ROM and/or continue to step 7 to
achieve JuopunutBear S-OFF, you’ll have to root the device yourself.
This is very simple.
Download Superuser ZIP
from androidsu.com/superuser. I can only recommend version 3.0.7 efgh
because that is the only one I have tested, but newer versions may work.
Place the “Superuser-3.0.7-efgh-signed” on the ROOT of your SD card. Go
to CWM Recovery and use “install zip from sdcard” to flash the Superuser
zip. If installation aborts or fails the first time, try to flash the
zip again until installation is complete. Reboot your phone and check in
your apps to see if Superuser app is there. If so, congratulations, you
have successfully rooted your stock MT4GS!
-7. USE JUOPUNUTBEAR TO GAIN S-OFF (OPTIONAL).-
Achieving S-OFF will make your life a lot easier if you want to flash custom ROMs, especially ICS ROMs. Follow instructions for
JuopunutBear at unlimited.io and check out the
JB S-OFF thread for other users’ experiences.
As I said before, if you are S-ON, flashing ICS ROMs will require an
extra step in fastboot. You will have to extract the “boot.img” from the
ROM and flash it with fastboot after installing the ROM in CWM
recovery.
More information from Limewirelord.
If you are S-OFF, you can bypass this step. For this reason alone, I
highly recommend JB S-OFF if you have a half hour to spare and some
courage for the wire trick.
In this post, Indirect explains why JB S-OFF is superior to S-ON and Revolutionary S-OFF. Also,
S-ON Unlocked, Revolutionary S-OFF, and JuopunutBear S-OFF are described in detail here.
However, if you plan on staying on stock-based/Gingerbread ROMs, S-OFF
may be unnecessary for you. There are pros and cons to staying on 2.3
Gingerbread vs. upgrading to 4.0 ICS (like the stock HTC camera), but
I’ll let you make that decision for yourself.
JB S-OFF NOTE: Users have reported that certain SD cards prevent JB
S-OFF from working properly. If the wire trick doesn't work for you, try
using another SD card and make sure it's formatted to a "FAT" file
system and over 512mb in size (thanks to demkantor for this tip).
