Member Info
Can someone tell me in which part of the partitons the driver of the touch is installed?, boot.img, preloader, system etc etc, becuase how is posible that the touch driver cant work downgrade if you format the this partitions and you cant downgrade to other version? or the firmware is installed in a memory of the touch screen? I mean like a nand in the touch screen that cant be downgrade? so thouse drivers are not in any of the partitions like boot.img, preloader etc etc?
Has someone tested new ROM (8/16/2014) ?
- is "caller ID" bug fixed?
-any chance GPS has been improved?
Is this a new version 25.8.2014 of Kitkat? Does this have also the display bug?
20140816 is the new version. KitKat V3.0
G4S-20140816-190609-V3.0.zip
No display "bug" in V3.0 firmware.
My original phone 5month old updated and screen wake touches work
Double tap works.
What about caller ID bug?
Any other Bugs known or other improvements? SD-Card mounted, vibration notify of the "keys"…is it importend to know which display is build in?
Work whitehall g5s?
Work whit g5s?
root not working in this latest build. To fix it, you have to download a fix, rename it to boot.img, replace in ROM folder and then flash it:

tested your boot.img and all good!
Phone and contacts are in chinise, have anyone change that?
Rom Dialer make connect with China. I remove it and install one dialer from google play.
Caller ID bug is not solved
When the incoming call phone no. is not linked to your contacts, add the following line to your build.prop file:
ro.init.phonenumber_match=7
This worked for me.
I store all my phone numbers in international format, e.g. +31612345678
With this fix, the number 0612345678 matches the international notation.
