Hey - do the following to tweak your Jelly Bead powered Sinotec M735 to Android Kit Kat (v4.4)
- Download and extract the zipped file here http://d-h.st/f6b
- Move all three APKs contained in the zipped file to your phone if you were using your computer
- Now install all three APK files starting with the i) PrebuiltGmsCore.apk then the ii) Velvet.apk and lastly install iii) GoogleHome.apk
- Press and hold the home button and then select the launcher.
There isn't an official 4.4 update available from Sinotec so we can not go the 'Settings > About table > System updates > Check for updates...' route.
