Update 04/10/2013
- Rom G3 4.1.2 for CWM
- G3_TO_G3N Transformer pack for CWM
- Patch: WAKEUP volume +/- for CWM
——————————————————————————————————————————
Features ROM:
Note that there are two different examples of G3:
1) G3
2) G3N
1) has a chipset MT6620
2) has a chipset MT6628
how to recognize: all devices with build (in product info): 20130223-071508 G3N and later fitted with a chip MT6628, the oldier mount MT6620 chipset
the roms for the G3 are not compatible with the G3N and vice versa
differences:
flashate if a wrong rom (for example a rom on G3N G3) not work properly: WIFI, BT, FM radio and GPS, so if you do not work none of this hardware, you probably have the wrong rom, download the one for the other device and riflashate .
said what '…..
JB custom roms 4.1.2:
1) ROM for G3
2) transformer pack From G3 to G3N
IN MY ROMS JB 4.1.2 The Tethers ARE PERFECTLY WORKING!
settings added:
in developer options: factory mode and engineermode launcer;
in management sim, dualsim Ringer settings
fixato dualsim ringer and added some scripts to:
optimize and speed up your system: Zipalign, optimization and system ram, and supercharger
(If you do a restore after the installation you lose a part of the supercharger script …..)
more … in: -> tethering / portable hotspot: Ervius tether natter settings
updated boot logo, changing image!
applications that are put in settings are invisible in "programs"
optimized still the build.prop, and, of course the old changes:
reduction to 10 ms vibrio button operation
SMS long (No more self-transformation in mms sopo 3 concatenated SMS!)
extended PowerMenu (adding the "recovery" to reboot in recovery mode)
disbilitato the red LED to charge less than 15%
stretched to 5 seconds the flashing LED notifications (blue and green!)
dialer buttons marked.
ATTENTION ALL ROMS MAKE A FULL WIPE! (Before flashing make a full backup of your system and data)
you can 'perform two types of installations for the roms
a) clean istall: installed the rom from recovery modded!
b) istall with recovery: from clockwork mod, make a backup (only data and cache), installed the rom, you restore and reboot, you will have all vistri data and programs but on a brand new rom!
PS: If you come from a ICS 4.0.4, nn do a restore after you have installed the 4.1.2 JB, or the phone to reboot will go in boot-loop (nn will start and you will have to reflash the rom!)
Language support: AR/BN/DE/EN/ES/FA/FR/HI/IN/IT/MS/NL/PT/RU/TH/TR/UR/VI/CN
Install ROM:
Only add to the procedure used with Recovery LEWA:
1) Backup essential, always.
2) Factory reset
3) Wipe Dalvik cache and cache
4) Install zip (Rom)
5) Wipe cache and Dalvik cache
6) Reboot
So start the first time, quickly and completely clean.
With Titanium restore all your applications.
※Please make a backup of your device before installing or updating ROM
Thanks to ervius for this ROM, great job. Only one thing which make to I´m not full satisfied is GPS accurancy. Is there a chance to improve it (how can I help)?
not for now…. I'm testing another kind of rom, if works better, I'll post!, but for my use, GPS worked ever well!, never had problems with it!!!
tried again this morning, vol+-wakeup_4_1_2 perfect, everything works fine
thanks again ervius…
vol+-wakeup don´t work on my G3 – it is for G3N too or not? I try to flash it, but volume buttons don´t wake up phone (flashed in lewa recovery).
it should work in both 4.1.2 versions!
ervius
vol+-wakeup don´t work on my G3N too!
I have tried to install .zip from Leva CWS and also manually just replace the mtk-kpdl.kl file frm zip to the /system/usr/keylayout/ using root explorer – result = nothing!
Also I have "near developer" question:
Also, as I have reviewed mtk-kpdl.kl – is just a text file with mappin: keykode – action, I have manually have replaced action for 115 key (by memory – it is volume up) to WAKE – and nothing effect! Does it enough just modify this file with action or it is also some binary should be patched too for to understand these mappings?
no, only that file….
Hi Ervius. Thanks a lot for your work. Are you planning to release a 4.2.2 based ROM? Maybe a Cyanogen one or something similar?
Thanks a lot for everything.
Cheers.
if there is something similiar for dualsim phones, I can try ti port it!!!!!
Hi Ervius.
I found this one based on CM10 for the Jiayu g3.
http://forum.xda-developers.co.....d.php?t=2163707
The best thing would be port CM10.1, which is based on Android 4.2.2. Is it possible?
Let me know if you need any help or info.
Thanks!
no, it's a 4.1.2 version…..
Yes, that one is based on Cyanogen Mod 10.0 which is based on 4.1.2, but there's a Cyanogen Mod 10.1 based on 4.2.2. Is it possible to use this ROM as a reference to port CM 10.1 to Jiayu g3?
Dear ervius!
maybe would you put the Hungarian language into your ROM please?
Thank you: Zs
What is the different between G3 or G3N?
Thanks
the 4-in-1 chipset that make working: WIFI/BT/GPS/FM Radio, the G3 has the MT6620, while the G3N has different chipset: the MT6628.
Thanks for the rom. It seems good so far. The only thing I have noticed so far is that none of my music apps can locate the music files on the sd card. They all play individually but don’t appear in any of my players. I have tried several different media or sd scanners without success. Is there something I am missing?
I fixed it. For some reason when I opened a video player and pressed refresh button all the files became visible in all the apps. Great rom. I have had issues with many other roms when playing music with many glitches. This one seems to be a lot better. Thanks again.
