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
how can I enable volume keys wake up?
see link in 1st page (my last reply!))
Ervius thanks for your work, smoothly work but i don't known why in system settings have a menu: Dock? How to use it?
not need, only if you have a dock station to charge battery….. if you insert phone into it you hear a "beep"……
So this rom doesn't have any bugs as I understand? Better than LEWA's last update ?
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!
Hi ervius, the rom looks good. Found some minor bugs, not an issue
1. If lcd density set, i use 270, the lock screen center ring is offset towards right, with stock ics, with 270 lcd density set, its centered.
2. Each sim slot is either 2g or 3g, in stock ics i could use 3g on any sim slot
3. Is there a transparent status bar for this rom. Seen on russian forum
4. Can u add 2/3g shotcut in status bar ?, so its easy to toggle ? In cm10, u can do this.
5.factory menu is in chines, can u mk it eng ?
for now, only can help you for factorymode into English (it was in English language only for Italian users!!!) try this, it is allways in English language!

P.S.: all zips are for clockworkmod!
How about that unlocking with volume button, just install the zip from sd card in recovery or how to install that file please?
Thanks for the rom, everything is working here!
yes u can just replace the mtk-kpdl.kl file frm zip to the /system/usr/keylayout/ using root explorer. b4 replacing the old kl, take backup of the old kl file.
@hanu_blr .
Can you be a little more specific please? Thanks, Max
only have to flash that zip with clockworkmod recovery ane restart device.
Thanks ervius! Great job!
ROM for G3N:
GPS: is not working (can't find any satellite)
BLUETOOTH: in car set is loosing connection and reconnecting every minute
// Those are my observation I would be glad if someone can confirm.
In my phone with G3N GPS works, but no very good. FIX is very long (even with A-GPS and GPS EPO assistance, allowed network to request position). Accurancy is not good.
Great rom.
The fact that the ringtone doesn’t loop was because android doesn’t loop mp3 ringtones, only ogg ringtones.
Gps is still crap but that can’t be helped.
