    how can I flash the UPDATE ? I copied the .ZIP file onto the SD card, bur the install proces by using the CWM recovery ends with status 7 error.

    I did not understand the description above :
    “Select a the in MT6577_Android_scatter_emmc.txt 592zn-g3-4.1.rar”

    Where can i find the scatter file ? Should I extract the .ZIP archive ?

      SO I need to nstall a special version of recovery first ? A already have a CWM Recovery v5.5.0.4 on my G3. I want to flash the LeWa_Jiayu_G3_ROM_12.12.14_5.zip – the updatet ROM version.

      Flashing using the CWM I have on the phone give me a Status 7 error

      you choose the method you want to recovery

      I prefer the method Flashtool but be careful

      backup before

    This is what I have been waiting for, great Rom, thanks.

    I installed the first version as I had the same status error 7 when flashing through CWM.

    Will try the update version later using flashtool.

      Just tryed to use Flashtool, but can’t find the right scatter tool that loads all of the modules.

    I had the same error (status 7) I think that is because you have the signature verification turned on. Try to turn it off.
    Moreover I installed the recovery of Lewa carrying default turned off the verifications and ran to the first.
    I hope you will help.

    Does anyone know how to put in another language other than English or Chinese? I would like in Galician or Spanish

    I’m sorry I can not understand. Updating ‘LeWa_Jiayu_G3_ROM_12.12.14_5.zip’ is an android 4.0.4, below one ’592zn_g3_4 file. Zip ‘which is 4.1.2, how can be an android update a lower version?
    Moreover in the version 4.1.2 does not work the camera in landscape mode or 3D mode. Can we fix it?

  8. 12/28/2012


    Finally I found the solution to properly operate the camera in version 4.1.2. Just downloaded this file


    and flash it from the recovery after the ROM.
    After all the drawbacks I have to say it’s the best ROM I’ve tried so far.
