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
where??? on fatory reset????
becouse, in my opinion, is the way to have to work.
btw, if you're telling about rom flashing, I prefer that you install a fresh, clean rom, after, you can make a restore of your backup!!!!!
I'll keep that in mind and yes it was after the 30/04 update
Thx!
Could you please change those ugly numbers icons when you dial a number? Please put the original ones :S
I like that marked numbers!!!
Hey envius
I cant seem to get a 3g signal,a only get the H signal.i thought maybe you could help.i leave in greece.Thnx in advance
sometrimes, when H doesn't work, I've seen the 3G icon near gsm signal, so, for me, it works!
I am using your mod more than three weeks. Thank you very much. I think it is best rom for Jiayu G3-G3N.
Hi Ervius, Could you do something to change the mobile's screen when incomming call, please use wallpaper or another picture if user don't have photo in his contact.
can you add bulgarian language
hi guys,
first of all: thanks a lot for the ROM. I am happy with it!
I have only one, but serious, problem! Since there are so many replies on this rom and no other one is complaining about my problem I think it has to be a setting problem.
The problem is when I choose "mobile network settings – gsm/csdma auto" and once the phone has dialed into 3G-network or HSDPA I am not able to make and receive phone calls and also I have no data connection available (cannot browse the internet) although the status bar say I have a good signal strength and the "3G" icon is show beside.
I have tried all the settings availabe when dialing "*#*#4636#*#* – phone information":
*WCDMA prefered
* GSM only
*WCDMA only
*GSM auto (PRL)
* (CDMA excluced since not available in my region)
the only option which works well (which means be able to make and receive phone calls and having a data connection available) for me is "GSM only", but with this setting I have just EDGE-connection and (of course) no 3G-connection.
any ideas? thanks!
just found the bad setting. in the APN settings the authentication type was set to “PAP”. I have set it to “not defined” and now everything works fine!
Great ROM Ervius. I'm not still installed the 2013/04/30 update but I'm very happy with your ROM. Only a question. It would be possible to difference between the volume of the calls and the volume of the notifications?
Thanks in advance
could be a good idea, maybe in a next release…..
Hi, I need to root my g3 before use the titanium backup, will I lose any data or apps if I root ?
No, root doesn't affect any files/applications in your smartphone.
Well, aside the ugly number buttons in the Dialer(found an app to replace it) and some minor performance issues in the menus, this is a good ROM, keep up the good work ervius
