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
Damm, that error in sd happend again.
This morning i was recording videos with no problem at all.
In the afternoon, i went to gallery, and it was ok. I opened one video, and ok. Suddenly when i closed the video, thumbnails in gallery started to disappear.
I shut down the phone, extract the sd card, and voila, almost all data corrupt.
Again garbage names, even in the name of the volume, and again partition programs crashed.
Finally, i was able to recover about 70% with photorec, but i am really in panic mode about using the phone again to take videos or pics.
I’m going to try a 32 Gb class 10 sd card and i will post my results
Is your card sandisk? I had similar problem and got card replaced from them.
New card came in post today and seems to be working.

Looking to upgrade my rom although not had experience doing it myself. My Jaiyu G3 MT6577, is the G3 rom compatiable with this as it says…
1) has a chipset MT6620
2) has a chipset MT6628
Thanks
hello. I tried this ROM and GPS was very bad.
I used mobileuncle tools to improve GPS and fastergps from google play to set correct server and other stuff
You need active a-gps and EPO.
The Wi-Fi signal and 3G is more weak and slow than original 4.0.4. Why? Have a solution?
Great rom, thank you so much!!!
my screen went white. Any ideas? I followed the instructions word for word and my screeen went white.
Followed your instructions but my screen went white when trying to load the transformer pack.
Any ideas???
hi ervius, This rom gives very poor antutu scores (5300-5500) and games don't run smoothly like temple run,
Any advice for smoother performance?
also works on jiayu G3S mtk 6589T quad core 1.5?

Hello ervius,
do the rom support cifs? Or have you a rom incl. kernel to support this .
I use your version from G3 20130116-21032013-ervius and look for a new with the posibility of cifs/md4/nls_utf8.
thx for your answer and "good" work
