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

Hi Ervius, I am very happy with your 3GN rom. My 3GN is fully functioning now. You have done a great job. However I see improvement posible for the GPS. With the original rom I had a fix inhouse within a minute. Now I only see get a fix outside and it takes longer. Do you have a clue which modules are involved?
Thanks Bart
Hungarian language – could we ask to put it in?
no, sorry, don't ask for different languages, I cannot update all files into ROM to insert new languages.
Chipset MT6628 for G3N, a lot of people said it is worse because its wifi is slower! Is this true?
I compared the two datasheet and I have to say that technically the 2 chips are identical in wifi.
Then why cheaper, than the normal G3? Lot of people said that!
I think that it is not cheaper, but if it is, then the reason is the quad core phones!
What I saw difference was that in the 6628 there is not FM transmitter.
Thanks! And where had that datasheet read?

Ciao Ervius! Ottima rom! ho solo problemi con l'audio.1) non riesco a mettere il muto se il telefono squilla in chiamata 2) anche se il volume della applicazioni è impostato in silenzioso, durante l'avvio di alcune applicazioni parte per alcuni secondi il sonoro. Per il resto è stupenda. ottima la durata della batteria. ciao!
I can confirm that the wifi is slower than with the other roms. But this rom is awsome it's oke! but for a next update please fix this:D
