Here you can find libcameracustom.so from V2:
libcameracustom.so.v2.zip
Thank you very much!!!
how can chance dialer and contacts from v2 ?
You can install contacs v2
Download file
to fix the dialer you can create a shortcut, use quickshortcut https://play.google.com/store/.....d.quickshortcut select activities, find dialer and create the short cut, you must delete ContactsHub to dont have the chinise contacts and dialer in chinise anymore
Titanium backup/restore works on V3 version?
Yes
Does anyone have a fix for Hackbarth's display problem?
Despite the warning, I flashed this ROM on my G5S-16GB/2GB. Now the touchscreen is completely unusable.
I thought flashing an older G5S official ROM would fix the problem, but the problem persists.
It looks like the screen calibration is overwritten somewhere, but can't be overwritten again by flashing a compatible ROM.
Try choosing "Format All + Download" on flashtool with G5S stock rom, backup all your important data on internal card though since they will be wiped out.
There is nothing you can do.
You can just wait for a new ROM specifically made for G5S.
Is there already a solution?
Can anyone confirm that wakeup gesture (double tab to wake up screen) works after flashing this rom. Also, does it only work for LG touch screen? i dnt knw if my fone is LG touch screen or not.

It works on my G4S with auo45 display! All other gestures are working, too! "Smart Wake" is great and doesn't drain battery!
how to know which touch screen my fone has??? i bought it like 3 months ago…thanks
Open a terminal and type cat /proc/cmdline
You'll see a long string, look at what's after LCM=
Or open Mobileuncle Tools, go to Engineer Mode (MTK), shift to the right to Other extra, press on Device Info and look at LCM:
this new android 4.4 for jiayu g4s have a language "português (portugal)"? I have android 4.2 and he have "português", but is a "português (brasil)"…
Path do not work… keep force closing.. this happen in all kitkat rom
hi, ferreira05, this problem it could be correct with programe "languages" on playstore. put g4s in root-mode a instaled,afhter open program and select pt-pt. in think if v3 have the same "bug" it will work to.
How to fix the caller ID problem:
1. Root your phone if not already rooted
2. Add the following line to the build.prop file:
ro.init.phonenumber_match=7
3. Go to settings > Apps > All > Contacts Storage > Clear Data
4. Reboot
You can use this app for editing build.prop: https://play.google.com/store/.....itor&hl=nl
or use adb push / pull
many thanks pkfloyd!
