This is the video-guide to upgrade your zp900 from Android 4.0.4 ICS to Android 4.1.2 Jelly Bean.
First of all you need to have installed the ZP900 Drivers on your computer. You can install it manually or use Snappea for an automatic installation:
1. http://www.4shared.com/zip/YXlLF … nstall_3_steps.html
2. Install driver via Snappea –> http://dl.snappea.com/release/SnapPea_22.214.171.12417_newuser.exe
Now you need to download the ZP900 Jelly Bean ROM 4.1.2 + all tools you need to have in order to flashing your device, extend up to 2,5GB the internal memory for app installation , CWM Recovery, ROOT (SUPERSU) , MTKDroidtools and Flashtool, all is compressed as ZIP in the same link 😛
Just follow the video-guide instructions and have fun ¡¡
Special thanks to my friend @Gordonfire 😀 for providing me the CWM Recovery for ZP900 and SuperSU-v0.96 for zp900.
P.D. I’m still working on the intructions.. I hope to complete them tomorrow.. meanwhile you can see the video..
