ROM JIAYU G3 and G3N – ROM Android 4.1.2 Evolution by Jolufa

EVOLUTION ROM by Jolufa R.O.U. For G3 and patch JIAYU G3N

After about a month that I've uploaded the ROM (over a thousand downloads, I've received the total of 1 euro as donation. Thank you again) I'm updating this thread  probably for the last time.
It is not a whim or unwillingness simply means I don't have my G3 and I lost interest, plus I have no way to test the changes.
I'm without phone, by necessity I had to sell my JIAYU G3 and now I have a ALCATEL OT-208 … Ha Ha …
Well, expecting a C2 ZOPO shortly.
As always, however, I am at your command.
Catches are different now, I have no way of making them.
He had the ROM on my MicroSD and so could upload, is what I was.

Change Log:

Version 1.3 (were reduced enough sizes both versions, the "light" even more so)
Most successful and aesthetically pleasing (at least to me …)

Hello, how are you?

For a couple of months I've been using (after working many, many hours on it) a ROM based on the latest available from the factory for our JIAYU G3.
Therefore I refer to JB 4.1.2 beta.
Like almost all previous ROMS, of all my previous phones and this one in particular, the development was made for personal use; suited to my tastes and needs. Normally not public. In this case it seemed good to share to the community.
Well, let's start with the description.
Try to answer the following: What was changed? What was it added? What was taken away? What makes it different?


Note: the ROM boot in spanish lang, if you want another lang, please use the included Prop Editor or MoreLocale from the Google Play to set your preferences.



Evolution ROM is and always will odexed.

Odexed ROMs offer increased application execution speed, lower memory consumption and improvements in code execution.
The disadvantage would be when decompile, modify or apply themes.

Mainly as I said above is based entirely on the official ROM provided by JIAYU. What does this mean? Have tried to touch as little as possible, to get a good performance and reliability.
This is undoubtedly a ROM balanced between performance and battery consumption.
From experience I am guided by the scores given by Antutu for example (I made a test immediately after the previous one has given me up to 1000 points difference without having touched anything), but I do not mean to have low scores or poor performance. He has given over 6000 occasionally.
Rather, what I mean is that do not necessarily go hand high scores and usability. Do you understand?
So if you're of that is based on test scores or installing a ROM is probably not what you expect.
If instead you want to try a ROM balanced, with everything working perfectly, this would be an option to take into account.

Added the following applications:

A1 CPU Tool_0.9.1.apk
A1 SD Bench_1.3.1.apk
AppDialer Pro_3.7.2.apk
BuildProp Editor_1.0.apk
CallRecorder_1.3.9 full.apk
Clean Master_3.4.0.apk
CPU Sleeper_3.7.apk
CPU Spy_0.4.0.apk
File Explorer_3.1.6.apk
GO Backup_3.3.apk
Google Play services_3.0.27 (599131-10).apk
GPS Data_1.15.apk
Installer cracked GooglePlay_1.1.0.apk
Lucky Patcher_3.1.6.apk
Mobileuncle Tools_20130223v2.8.0.apk
MX Player_1.7.15a.apk
My Tracks_2.0.4.apk
One Power Guard_2.8.apk
Software Data Cable_4.2.1.apk
TimeZone Fixer_1.3.4.apk
TimeZoneDB for ClockSync_1.1.2.apk
Titanium Backup_6.0.4.apk
Total Commander_2.01.apk
Weather Services PRO_2.1.4pro.apk



Removed several unnecessary applications, animated wallpapers:




Chinese Applications removed:



Installation Method (installable from the Recovery):

     Make full system cleaning (wipe data / factory reset). This will erase all data, make a backup if you need to restore.
     Install the preferred version (full / lite).
     Restart the phone and wait for it to load the system. If a Root repair message we say yes.
     Open [Settings] -> [Access location] -> enable [Access My Location], enable [GPS satellites], enable [Mobile Network Location yy Wifi]
     Click hablitar GPS Satellites [EPO] and [a-GPS], download EPO data using WiFi or mobile data.
     Go to an outdoor location (I mean not covered) and make the first fix with GPS Data.
     Optional / Recommended: Run Busybox, super user / her in that order (a new compilation is automatically granted root permissions without asking)
     Optional / Recommended: Run CPU Sleeper and mark [Auto Start-Up] -> [Start CPU Sleeper] and One Power Guard [IA Mode] -> Settings -> Set On Boot -> Restart Protection
     Optional / Recommended: Run TimeZone Fixer -> Update files

Patch G3N conversion (Not tested, I don't have one 3GN to test, but it should work because it is generic, the one difference is the chip 6620-6628)


Q: How do I know if my JIAYU is G3 or G3N?
A: Certainly there are various ways, basically the difference between the two models is the radio chip that handles all wireless communications, cellular signals read proper radius (GSM, 3G, FM) wifi, bluetooth, etc.. Using the included MobileUncle Tools is simple:

MobileUncle Tools -> Mode Engineer (MTK) -> Connectivity -> Bluetooth -> Chip Information:
If says MT6620 is one G3 or G3D.
If says MT6628 
is one G3N or G3DN.


Q: Are there plans for a deodexed ROM?
A: No. No plans at least mine. I will offer a version of Evolution deodexada ROM, even in its updates. That is something that anyone in the community can if you want.


Q: Can you add a particular application?
A: In a short answer, yes. I can. But I will not make a request. Anyone can add the applications you want. The ROM is in a ZIP archive and is very easy to do on your own.


Q: I do not use a particular application. Can you remove it from the ROM?
A: As is stated above, applications can be removed easily by everyone. I can not customize ROMs each.


Q: The file is very large and do not need so many applications
A: I put a version available light, light or lite without most of the applications of her older sister, leaving only with Titanium Backup and a couple of applications under 50 Kb to control CPU.


Q: What version of the G3 is? Does it work with the G3 or JIAYU JIAYU G3N?
A: The work was done on the basis of the latest official ROM G3 model, the part is available downloads a patch (untested by me, I have no G3N for testing) to convert from G3 to G3N, so theoretically there would be problems to work in both versions.


Q: I can modify this ROM and it as the basis for my own development?
A: Obviously, the spirit of Android and the community is that exactly. Share knowledge and means or resources for the good of all. Furthermore Evolution WTFPL licensed ROM (Do What The Fuck You Want To Public License). It would be good to add a mention. If possible I would like to know the project or modification. Nothing more.


Q: How I can thank you / help you?
A: Well, leave your comment or give thanks with the corresponding button is enough for me. But … if you can and want to do more, I could use a donation of whichever is, no matter how little it may seem. With sand grains consist deserts.
I am paying and administering a server to host the downloads and other files to the community. I pay out of my pocket and I really would aid with that. I also broke the screen of the computer I use for work and I buy a new one. Any help serve. Even for a coffee or buy an ice cream for my children …



Let me clarify, I ask nothing. I'm just saying that aid serves me.


Greetings and at your command.



Google translated, sorry.  :-)

    Thanks for the rom. 'Modded By f000h' popup is anoying me, but overall rom seems to be good. I didn't play much with this. Do you know whether this will work with bluetooth car kit? Most of the rom I tried failed sync contact list and call list. But some how in current rom it works(Official 4.1.2,  I think, I also applied with bluetooth fix app, but credit is finished now). But when I was using Star X18i 2.3 rom, it was working with any fix. Do you know anything about how bluetooth car kit sync the call list or contacts or which service in android? Thanks

      Remove appdialer (to forget popup)

      Sorry bro. I don’t have / car kit (or car) to test this. About the battery life, please test lite version (less services and background apps) and make full battery charge/descharge cycles.
