[LWX49K&LDZ22D&LCA43] Rooting made easy

[NUT] · May 13, 2015

I'm not believing my eyes just yet, but honestly...

Want root? Well, then I have some good news for you:

THERE IS NO REASON TO UNLOCK YOUR BOOTLOADER TO ROOT YOUR SMARTWATCH 3!

The fastboot mode is available on locked bootloader...

And the best news I can come up with right now? It allows hot booting custom kernels! :victory:

Code:

~$ adb reboot bootloader
~$ fastboot oem unlock
...
(bootloader) : WARNING: Unlocking your device will void your warranty
(bootloader) : and erase your personal data from the device.
(bootloader) : Run "fastboot oem unlock" again to confirm.
(bootloader) : Device still locked. 
OKAY [  0.008s]
finished. total time: 0.008s
~$ fastboot reboot
rebooting...

finished. total time: 0.001s
~$ adb shell
shell@tetra:/ $ su
root@tetra:/ #

I can't believe it myself, but it's TRUE!

:victory:

I have rooted my device using the TWRP from this thread, this is what I did:

Made sure I had the developer options enabled;
Enabled the ADB debugging option;
Made sure the device accepted my PC as authorized;
download the TWRP image from this thread (for 5.0.2) or from this post (for 5.1.1);
Download Wear-SuperSU-v2.46.zip;
adb reboot bootloader, saw it actually boot to fastboot... this is how I looked at that time: http://images.sodahead.com/polls/001047815/gobsmacked-15792349304_xlarge.jpeg;
fastboot boot unofficial-twrp-2.8.3.0-tetra.img (incredibly I saw it boot TWRP! Well... this is like the face my colleagues where watching me pull at that moment: http://mcp53.files.wordpress.com/2012/11/gobsmacked.jpg?w=500);
adb push Wear-SuperSU-v2.46.zip /sdcard/ (installed the zip in recovery);
Reboot to system from TWRP;
Did root test;
Was seriously gobsmacked.

I'm investigating the possibility to have recovery on the locked device right now, which is actually something I did for many Xperia Z series devices already :angel:

What can we make of new after this?

Well, the good thing is, you can have root while you won't lose your warranty. Because unlocking bootloader === lost warranty.

What else we can do, the sky is basically the limit... or, the resolution is, of course

Oh nice!

And with root in this Smartwatch, what do you think that we can make of more?

Well, one of the things we might be able to do is create an app or a ROM modification, which will run on the ~~phone~~ smartwatch itself, allowing you access to the internal storage by USB cable, because that's not possible without a phone right now. Knowing Google, it was done by design, but it won't be hard to update the ROM to allow access to the internal storage through USB.

I'll be trying to get a recovery working on the device without overwriting the one in the recovery partition, which should then allow us to easily flash ROM modifications.

Dude Great to see you here, i am very excited now as our SW3 will go in right direction, i have Asked Jerpelea about the Development of SW3 and he said it will start soon.
Also its a request Plz make a custom Kernel for this watch to Calibrate the Colors saturation and Gamma as its same yellowish Display as Honami had.

Is there a way to unlock the kernel and all four cores in the processor on latest LDZ22D build for Smartwatch 3?

Thanks for sharing your discovery!

I wrote an article that explores the bootloader vulnerability: http://spectrastudy.com/no-data-protection-on-sony-smartwatch-3-android-wear/
An Android Wear dev advocate at Google is now informed of it, it really should be fixed as it makes stealing data far too easy.

Hi ive been trying to work this out above you said that there is away to root the watch on locked bootloader could you explain how? I can get into fastboot but theres no way to install TWRP on locked bootloader how would I flash the superuser zip on locked bootloader. Can it be done? Your method you explained is an unlocked bootloader method and with the stock recovery you can only sideload update.zips correct me if im wrong. Can you please explain the locked bootloader method??? Can it not be done on the latest build LCA43???

fastbooting hotboot only. no flashing of custom recovery. only flash wear supersu after hotbooting.

Just one other thing how can I check I have successfully rooted my device?

jemfalor · Aug 25, 2015

sideload an app and use its root feature. es explorer or terminal emulator

Or use ADB Shell to use the su command to gain root access.

Ok thank you both the root features in es are very limited so its hard to tell I will try the su command later on thanks for that NUT

Edit: I did try TWRP on the latest firmware in the end LCA43 and it was successful im still yet to see if root was successful I dont have a superuser app is this normal?

karl0ss · Aug 25, 2015

This all works on the latest Android Wear build as well
