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
Hello ervius,
Any help for my previous comment??

Hi ervius,
Thanks for your work. Can you help me solving my bluetooth syncing problem in car kit? I am having nissan bluetooth kit. I can pair to the car kit, can call. But cannot sync contacts or call history. It is working with one rom, I think I have applied the bluetooth fix repair app, don't know, because I tried many apps and tweeks, cannot remember what I did. If we can solve this bluetooth issue that will be great. And also netflix app won't work in any of the 4.1.2 apps. Do you have any ideas?
Thanks. great job man!
ervius,
i see the stock camera colurs are more towards red tone
IF i try camera360, colors are normal there, any1 noticed this ???
I don't know about what rom you are telling, but, for G3, is only the 4.1.2 beta moddecby me, about G3N is last G2S from march, modded to work on G3N, if there are problems, maybe JIAYU original roms need to be fixed!
ervius, no issues, after clearing data for the gallery, now i see the colors from the stock camera are fine
Also if the phone is mute, for a few seconds I hear the alarm (for example Ruzzle)
evirus, out of interest, why did you choose to port from the G2S ROM and not from the G3?
it's explained into roms descriptios, btw, the G3N has a different chipste, from the G3 that has the MT6620, the G3N has the MT6628, same of the G2S, it was easyer use a G2S base rom to port to G3N
ervius, could you please be so kind to clarify – does GPS work for G3N (501) with G3N_MT6628_JB_4.1.2_25032013.zip?
if were some bugs, I wrote on descriptions…. all working into both roms, for both devices!
and, my answer is: YES: GPS works on G3N if you flash the rom for G3N!!!; so:
GPS works for G3N (501) with G3N_MT6628_JB_4.1.2_25032013.zip!!!
Anyone has tried to open , disassembling their G3?
Some dust have got under the glass covering the screen, don’t know how, it would be nice if I get to clean it!
Amazing rom!!!!
Hi nice job, thanx a lot, rom works great . I'm very interested in vol+-wakeup_4_1_2 too, but can't download it, anyone with same problem? Bye…
