Root Firmware 18.1.A.1.21

thejosetree · Sep 28, 2014

There is a way to root new firmware 18.1.A.1.21 . Tested by myself on my new Xperia T3 (D5103).

Follow the steps below. Credits to him: ( Taken from this post: http://forum.android.com.pl/f1428/root-dla-xperii-t3-456064/ )

1. Install ADB drivers. Follow the steps from this post (Method 1 better): http://dottech.org/21534/how-to-ins...ows-computer-for-use-with-your-android-phone/ IMPORTANT: CHECK THAT YOUR PHONE CONNECTS TO PC VIA ADB BEFORE PROCEED TO THE NEXT STEP.

2. With Flashtool, flash the .21 firmware, if you didn't have already flashed.

3. Turn on the phone. Active USB debugging and Install apps from unknown sources.

4. Turn off phone, and flash .14 kernel with flashtool. Download kernel from here: https://drive.google.com/file/d/0B-GorbT9vz2qSlczRHlPWGdKb1U

5. Turn on phone, and connect it to PC via USB. Doesn't matter if phone get stuck in "Updating apps" screen.

6. Download last version of root toolkit by cubeundcube: http://xdaforums.com/showthread.php?t=2559009. With phone connected to PC, launch install.bat from the toolkit. Follow the steps until the phone reboots.

7. Now turn off the phone, and flash again the kernel from .21 firmware: https://drive.google.com/file/d/0B-GorbT9vz2qQm91VU4wWnZvd28

8. Reboot and now you're on .21 firmware and rooted :good:

Do I need to exclude TA in flashtool?
thanks.

meilbox · Dec 19, 2014

as u dont unlock the bootloader there is no reason to do so...
also as for now .. can we even backup the TA partition ??
i've red that after relocking bootloader the drm keys are back ...

starterz · Dec 20, 2014

Confirmed. This method works very well, even if it is not a one-click method. Thank you.

Thanks, I finally did It

Once your phone is rooted, you can backup TA partition, but you have to do it BEFORE you unlock your bootloader. It won't be possible after unlocking it

If you back up your TA partition, then you can relock your bootloader using that backup, like nothing happened.

To enter flashmode - on your phone turned OFF - hold volume down (-) then connect USB and youll see green led.
@ryanxtx links are working correctly, ive just checked em. Its probably something with your browser/network.

ryanxtx · Jan 3, 2015

Thank, @horuxan. I've successfully rooted my T3. I just got today. I can't download last two days ago. The important is adb n fastboot driver for T3. It made me a bit headache but I have done now. Thank. ? ?
