Jiayu G2S - Android 4.1.2 Custom ROM - DAVID G (v.3.0)

This ROM is based on the official 20130306-143807 rom (only for G2S!)
The intention has been to make some improvements. All applications that have been changed or modified, have been done by David G also it is zipalinged. The added system applications have been modified, so it also changed the package name so automatic update on these apps won't work. For example, the added ES File explorer. The first version of this ROM is numbered as 1.7. This is because although it is the first available, its the seventh version made to find the balance between performance, consumption and stability. It should not have a single app or process to give a FC, performance should be noticeable and much better from minute one. Also because of the Apex launcher. Power consumption has been improved by eliminating unnecessary startup services and, above all, changing the default network selection to AUTO (GSM) PRL.

If anyone has doubts, remember: nobody is forced to install this rom. If done right it will work much better than standard. And you will realize this from the first boot.



Install instructions: (CWM)
* Enter recovery mode.
* Perform all wipes (data, cache, system).
* Optional (but recommended) you can format system (sometimes the recovery do not clean with a wipe)
* Install ROM zip.
* Restart and configure to your taste.

Full wipe method:
* Boot into recovery
* Wipe the cache partition
* Go to advanced and wipe dalvik and battery stats.
* Go back to mounts and storage and format system, then data, then cache.
* Go back and install the rom zip file from the sd card.
* Restart.

Some other tips:

You can install google keyboard if you don't like added keyboard. (you can download APK if its not available in market)
You can unistall or freeze the added system apps with an Root Unistaller. (download from market) 
If your country is other then Spain you have to change the gps.conf file to make your GPS work fine/better.
For example you can download fastergps or fasterfix and set the ntp server to your country or region.
Also dont forget to enable A-GPS and EPO (download new epo every month)
Settings>Locationsacces>hold GPS to enter advance menu and thick A-GPS and EPO.

You can link/upload this rome elsewhere but the original maker only asks that you state/link the original source. Orignial source: http://www.htcmania.com/showthread.php?t=627495 
Big thank you to DAVID G in my opinion best rom for the Jiayu G2S!

    Hi. I'm the modded who made this rom. Only two things:

    1. This rom was made for spain so there are any apps that only have english and spanish languages.

    2. To change the first boot language/country you must edit the build.prop and change:



    to set your contry/language and change:


    to set your time zone

    Does anyone knows if  Netflix works on this ROM? In other ROMs I've tried (e.g.  the official 2013.03.06-143807), Netflix cannot stream.
