    thanks but where can i get

    - Make sure you have installed MMX A110 Drivers from the virtual cd drive that is

    loaded when you plug in your phone to your PC. The drivers are installed in

    c:\Program Files\Micromax

    Here's hoping they put back in the Mediatek GPS EPO file trick. It's very useful if you're roaming out of country and can't A-GPS.

    Other than that, this looks to be really solid. I've been running it all day and find it at least as smooth as 4.04  -maybe better.

      Ignore the above- the EPO thing is still in there, but you have to click on the GPS on/off toggle and another menu appears.

      Great, great rom. Nothing beta about it.

    I did the update via FlashTools, SD Card update doesn't work.

    I followed this procedure: 


    the LED notification works, the camera is now focus.

    The big minus is a bug with the battery display. After 5/6 hours of average usage , I had only 36% left. I removed the battery then put it back and the display is now 56%. I'm still under the impression that the battery drains faster than the previous 4.0.4 official rom.

    Someone in other forum said that there is still the bug of "LEDS_WAKELOCK" that comes with the red notification led and don't leave the phone to go in deep sleep… It's very annoying to see this free battery draining… :-(

    I have installed this rom by flashing through brush tools. 4.1.2 seems to be better than old 4.0.4. 

    Only problem I have faced is the battery draining, I have calibrated using an app from google play, took the battery off, charged the phone while switched off. Now battery is little better, 58% remaining after 30 hours with normal use some wifi, camera and bluetooth operations. Is there any thing I can do to improve the battery life. I think radio consuming most of the power or may be the led wake as mentioned by the above poster. Somebody mentioned official rom will be available from 20th Jan (today). Is there any good custom 4.1 rom for Jiayu G3 with good battery life?

    The phone gets warm and the battery drains away.
    I am aware it's a beta release.

    Hello. I tried to do the sd card way and it wouldn't work. Keeps showing up with the android on it's back and a triangle sign. I'm trying to use flash tools but when I go to the list and look for the scatter file, it gives me the "incorrect scatter file format" message. I downloaded the jiayu g3 fl link above. Can anyone please help? Thanks much. Oh my phone isn't rooted.

      Please use the Jiayu G3 FL and the Tools Link to download. Then Unzip the files on your hardisk then detach the battery from your cellphone and put it back again but do not turn it on. Run The Flash tool that comes from the Tools link. then find the scatter file and make sure all of the check boxes are checked. DONOT US OTHER FlashTool version! Use the version that comes with the link then after that CLICK the UPDATE FIRMWARE button at the toolbar then that is the time that you will connect the MINI USB cable to your Jiayu G3 and wait till a SMALL window with a green cricle will pop up and you are done flashing the ROM. Disconnect the phone from the USB and turn it on. BE SURE TO BACK UP ALL YOUR FILES AND PHONEBOOK FIRST because it will erase all what is installed and all of the data on your phone.

      Thanks techbuddy. My problem was because I was using windows 8, I tried doing it on a machine with windows xp and it worked well (no incorrect file format message). Now using the official jb rom :) .

    Hello! I have downloaded the archieve but inside there are 3 items:

    1. AAAAB3NzaC1kc3MAAACBANLc2NCufBz0lBUupztiXI7rUnhY3bOojTMmGD0SR68e8kK00EM5n0ghfpaDxayZD.zip

    2. database – folder

    3. update.zip 

    Should I put database folder in SD card too for update?

    • 05/15/0470

      you have to put in sd card update.zip

      and create a folder



      but this method does not always work
      I advise you to flash
