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!
~$ 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 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/001...04_xlarge.jpeg;
- fastboot boot unofficial-twrp-22.214.171.124-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/201...cked.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
