Path is not compatible with all kitkat rom on jiayu g4s, anyone can confirm me?
@juliotec may bad i replaced the libcameracustom.so noisy camera in the v3
by the way how can you fix the contacts? its a little bit annoying it comes with a software which syncs accounts can we chnaged this to stock contacts? thank you
Did you overwrite the contacts.apk and dialer.apk from my link? and not working?
In addition to juliotecs instructions on page 9 of this thread I had to install contacts.apk V4.2.2 (I took contacts.apk from my 4.2.2 Rom backup, MTKDroidTools). Now "contacts" is running in german language!
hello,how to make sd card default write?thx
i have the 4.4.2. v3 , every time i prefer the greek language ckack the UI, if i prefer english anythink is ok!!!!!
solution????
I have the same problem , when i choose greek language the UI stop !
me too!
help fixing contacts and.the dialer
@juliotec posted dialer and contacts are.corrupted?
help thank you I tried installing other but went missing dialer and contacts
Delete ContactsHub.apk and IswDotExp.apk
Is there someone that the dialer and contacts that i upload is working too?
If your dialers and contacts are not working, put the contacts.apk and contacts.odex original rom v2 G4S-20140724-114258 and the dialer.apk and dialer.odex original from v3 G4S-20140816-190609 to system/priv-app but you need add a short cut from your dialer with a app from google paly named quickshortcut. choose activities and create the short selecting th dialer, the shortcut has the name like Dialactactivity or something that.
Anyone knows:
- Is it possible to instal any custom rom after instal kitkat v3? (with working screen)?
- Is Jiayu working at an update for screen problem?
No, is not possible to install any custom rom except a russian rom based on V2.
No, JiaYu is not working at a fix and they explicitly said they won't.
So the only thing we can do is waiting for custom rom based on V3?
V3 or even V2 if touchscreen is AUO
For the russian custom rom based on V2, try searching for AOSP racerevil.
