How to and FAQ for K8

To save Pablo11, Cyrux75, Maitrot, chiragjn and all those others that have contributed in this thread, the trouble of repeating the same instructions and to help new owners find solutions fast, i have made a compilation of the most useful posts in this thread. None of this is mine.

The thread starter could think of putting this in the op to save some trouble.

Dont use OTA if rooted! You have to go back to stock.

Android 101 : Read first

Pablo11 :

A general announcement to anyone thinking of modifying their watch.

Be careful !!

Please read everything about this process at least twice.

I have already had several private messages asking me to fix semi-bricked watches by posting them to me.

I have a family and a full time position at work and I cannot invest the time to fix peoples watches.

If instructions are followed carefully and the forum posts regarding MTK flash tools are read then there should be no problem.

As a rule - always;

a) full backup first including NVRAM for IMEI using MTK tools.

b) make sure all drivers for SP tools are installed correctly in case of disaster.

c) have the custom TWRP recovery installed on the watch - booting from SD recovery is no good if you can't boot the watch!!

d) make sure watch is fully charged before you do anything that may take some time.

e) copy the TWRP stock backup posted by me earlier in this thread to your SD card before you do anything significant - you can delete it after but remember this each time you do something that may prevent normal boot.

This way you can always boot into recovery without your pc and flash back to stock.

Lastly - take some comfort in the fact that it's actually very difficult to permanently brick this device. If you use the correct toolset you can revive the watch almost all the time !!

FAQ:

Does it have GPS ? YES

Companion APP? Swapp link and notisync work but this is not an android wear watch! This is like your smartphone. If you have two smartphones you can connect them through swapp link and check it out. There difference with wear is that it is optimized to be a slave to your smartphone.

Round screen means some buttons on the edges will not be accessible, try making it square (see above how) and think of using tasker to make a long press of a button to trigger the change (root required).

Does runkeeper work ? YES

Is the heart rate sensor and good ? Not if you are serious about it. Use a bluetooth HRM (Scosche Rhytm+ or Mio). Also the embedded sensor does not communicate with any of the known sport apps.

Can i change straps ? Well, yes if you dont use any of the antennas that are in the straps! If you are handy you can take the antennas out of the straps (they should be microstrip antennas) and stick them on the new strap, though the reception may be affected as the substrate of the antenna plays an important role.
