YOU CANNOT USE THIS ON THE LATEST UPDATE. IF IN DOUBT DON'T TRY IT.


This is ONLY for the Huawei MyTouch 4G from T-Mobile! This will not work on any other phone!

This phone does not have a trackball or physical keyboard, and is not by LG or HTC

THIS WORKS ON THE HUAWEI MYTOUCH 4G Slide Keyboard too!

It's definitely capable of running Jellybean with 1GB of ram. Just need CWM and the build to not hate me so much.

Well done. I'll be trying this as soon as my wife gets home. What are the chances of a brick with this method? Would you consider it very safe/reliable? Can I ask any details about how you managed to do it?

Edit: I'm just a bit hesitant...only because my wife needs her phone for work, if it were mine I'd be all over this. Any other confirmed success or failure with this method? Looks pretty elegant according to the .bat, simply fastbooting off a file sent via USB, not writing any files to the device until it's pushing the su on, not replacing recovery, etc, but I think I'd just be worried about getting stuck in fastboot mode or something.

This phone is very unbrickable. I rooted my phone with this (more than a few times now) and can 100% say this will not brick you. This uses "fastboot boot InsecureKernel.img" instead of a "fastboot flash" to ensure this even more. Worst case you reboot and everything is normal, but it would never get to that point.

When you boot the phone by holding both volume keys and the power button you will get a pink screen. If you are on linux or have the drivers installed on Windows, you will get a mounted drive, which contains boot.img and the recovery.img. I ran the boot.img through my insecure kernel tool I got from a buddy at XDA a while back and made an insecure boot.img. What an "insecure" kernel means is that if you boot using it your "adb shell" will automatically be root access on boot while using it. I use "fastboot boot InsecureKernel.img" to boot the device once with this method to mount /system/ so we can put su binary, Superuser.apk, and busybox in their respective places and set the right permissions. The phone then reboots and the InsecureKernel was like it was never there.

You cannot get stuck in any mode actually, just battery pull and unplug.

If you do crazy stuff with root on your own and "brick" you simply boot into a linux distro and replace the drive that pops up with the /system/ with a system pull while in Pink Screen mode.

Sorry if I got too technical, but you did indeed ask ;)

Holy crap, that exploit finds a hole as ancient as the G1s was. Wow, they must have figured no one would bother messing with this device! Nice deal Matt.

I'm having difficulties getting this to work on my Mac. I end up with this in the terminal:


Plug the phone in with a USB cord and have it booted up normally.
Please install the included drivers before we begin.
Go to Settings . Applications . Developer Options and enable USB Debugging.
If these are done press any key to continue.

< waiting for device >
        downloading 'boot.img'... OKAY [  1.052s]
                       booting... OKAY [  0.163s]
Phone is rebooting please dont touch anything.
failed to copy './files/su' to '/system/bin//su': Read-only file system
failed to copy './files/Superuser.apk' to '/system/app//Superuser.apk': Read-only file system
failed to copy './files/busybox' to '/system/xbin//busybox': Read-only file system
Setting permissions.
Unable to chmod /system/bin/su: No such file or directory
Unable to chmod /system/xbin/busybox: No such file or directory
Unable to chmod /system/app/Superuser.apk: No such file or directory
That's It!
You Are Now Rooted!

And the phone remains unrooted. Any ideas?

Thank you!

Dang, the mac version I seemed to have forgotten an important line..
adb remount
I will add it back in and reupload. Apologies.

EDIT: It is reuploaded. Same link as before.

Thank you for the explanation. Not too technical at all. So simple and elegant, well played my friend!

Now we need to discuss what bloat can be safely removed. I noticed some system apps (slacker, telenavgps, tmobile41) are installed into /data/data; Titanium backup backs them up ok but can't uninstall, says it can't find the apk. Now that I have a root shell I can rm them and have done so for some like slacker and telenavgps but the TmobileMall one, the MobileLife Contacts, T-Mobile My Account, I'm afraid to rm as I don't know if the phone will boot without them. We need to make a list of the bloat that safe to remove; if I were to remove the wrong thing I'd have trouble getting it back I'm sure. I'd probably need someone to send me the file and somehow mount the sdcard and put the files back or something.

Edit: I RM'd telenavgps -- rebooted and the damn thing was back!!! WTF?

Edit2: It seems they have some odd huaweivfs type file system - not sure if it's a cache or what. If you do
find /system /data -name *telenav*
you see all sorts of interesting things. I again removed it from /data/data, made sure to stop the service first. Did a find command again, nothing came up. Rebooted and IT WAS BACK!

Edit 3: This is so wierd. I can't find the apk that telenav is coming from, wildtangent is coming from, tmobiletv, etc. I think there's a master apk in /data/app that gets run on startup and installs those. Cause I blow away the /data/data dir for them, as that's all that comes up on a find, but they all come back after a reboot...

They are on a protected image that we cannot edit yet

Ahhhhh. This phone is very different from other android devices I've rooted and debloated. Huawei did some odd stuff. the phone is surprisingly nice for the price, though. Much snappier than my Samsung Galaxy S 4g.
So next steps are figure out how to debloat by accessing that protected image, and figure out how to get a proper recovery and new ROMs. The former I'm into, the latter I'm not, I'm fine with Gingerbread. Thank you for your efforts! I was able to install the hiddden Cerberus anti theft app into /system so it will survive a factory reset, and that was my main goal. Debloat is secondary.

My test rom didn't go so well :/ bootloops...bootloops everywhere!

https://dl.dropbox.c...mod Pheonix.zip
Run the batch and temp boot to CWM, select is the camera key, power key is the back key, and volumes are move.

It has random reboots so it is not something to be toyed with easily, but if you need a flash a small zip it should do the trick. This is possible of causing a brick if it crashes while flashing a rom after flashing /system/ :(

Hopefully someone can help me. I follow all of the instructions but I still cant get it to work. I'm running windows 7. I install the drivers, plug in the phone, enable usb debugging, then click on "root." From here the command promt pops up and says "daemon not running. Starting it now on port 5037. Daemon started successfully." Then it say, "waiting for device." At this point my phone attemps to reboot, but ultimately hangs on the "android 4g tomobile sceen." No matter how long I wait, it just hangs there, and the command promt just hangs on "wating for device."

Any help would be greatly, greatly appriciated! :)

@Saxman2k After installing the drivers click start then find drivertools in your start menu open that and select install drivers.

Yeah its either drivers or the USB Cable or the USB port you are using. You can try a different machine. I'll be in the chatroom for a bit
