Having Problems Try This: Newbies Might Read This Too!

Okay, I just bought my fifth XT926 Since last December (2014). The first two and the fourth I was able to use Towel Root, and (even though this DOES NOT APPLY HERE) motopocalypse to unlock the boot loader. One I sent back because it was updated, Why do people ever take OTA updates!!!!

Anyways I bought one with a broken LCD with the latest OTA, it came in the mail today and I learned of this new root method.

My first mistake was I did not realize there are two versions one for the XT907 and one for the XT926. I used the wrong one, so the flash to recovery failed. I kept getting stuck in fastboot with flash error, just kept typing fastboot continue, then eventually figured out if I successfully flash something, in my case I re-flashed the boot.img.

Finally I downloaded the correct exploit.: NOTE: the link listed on the page you copy and paste it, REMOVE THE SPACE between the DOT and the COM!!!!!

Next I would run the exploit script and keep getting to the Boot To Recovery Part and Have the "Dead Android Dude" with the word NO COMMAND. I tried this several times, no luck, so I edited the bat script and where the script uses fastboot to flashes the Kernel into the recovery partition, and then reboots back to Android, then uses ADB to reboot into recovery. Well I decided heck with it, I went ahead and booted into fastboot, manually flashed the image, reset the phone and held the power keys in and went directly to recovery, and it booted to 4.4.2 kitkat with the May Kernel, and I ran the Towel Root exploit. Then I made a copy of the script and kept the first few lines up to the "cd files" erased everything up to the point is says run towel root. I then ran that script to clean things up. I could have just manually typed it all but hey, I'm lazy.

For Newbies or People not too comfortable with Android in general. Be warned these steps take you a step closer to potentially damaging your phone, but if do these steps right no worries. If you do soft brick the phone, just use rsdlite or fastboot and re-image it with the latest OTA. I'm not going to cover that here.

Steps:

NOTE when typing all commands are in quotes, do not include the quotes!

PLEASE READ ALL THE STEPS FIRST BEFORE TRYING THIS!!!

From the Hydrogen PEROXIDE XT926 folder

hold the shift key in and right mouse click on the files folder and select Open Command Window Here

This will open a command window with the current path set as the files folder.

Type

"ADB Devices" and you should see the device listed, if not, search the forums for help.

"ADB Reboot Bootloader" This will boot into fastboot

Alternately after opening the command line window with the phone powered off press and hold volume up/volume down, and while holding press power for four seconds and release all the buttons. Then when the menu appears press volume down until fastboot is selected and then press volume up. This will also boot in to fastboot.

From the Command Line Window With the phone in Fastboot mode Type

"fastboot flash recovery root.img" You should get a message showing success, if not Stop Now because something else is wrong and I don't have an answer for you. :(

Next, take a deep breath and be ready to take action, as we are going to reboot the phone and before it has a chance to reboot, put it into recovery mode.

Type "fastboot reboot" as soone as the phone reboots (the screen goes black) press and hold volume up/volume down, and while holding press power for four seconds and release all the buttons. Then when the menu appears press volume down until recovery is selected and then press volume up. This will also boot into the recovery partition which has the older kernel, so actually the phone will boot to the 4.4.2. You can verify that things worked by going to settings about phone and the Kernel version should be dated May 2014.

From the Phone

Find the Towel Root App and make sure the phone has internet connection and then run it.

You should get a message saying it worked, next run the script I mentioned above with the first half of the steps removed and run it, this will put the phone's recovery image back and clean things up.

DON"T TRY THESE STEPS BEFORE FIRST TRYING THE AUTOMATED INSTALL_ROOT.BAT SCRIPT THE STEPS I MENTIONED ABOVE ASSUME THAT YOU INSTALLED THE EXPLOIT, TOWELROOT, AND THE SUPERUSER PROGRAM ALREADY. ONLY TRY THIS IF YOU RUN THE SCRIPT AND GET THE "DEAD ANDROID GUY WITH NO COMMAND" ON THE SCREEN
