    Hello people.

    So after a long search, I managed to find the method to install TWRP on my LG Magna H502f V10a.

    To do this, he must first root phone with the method: LG ONE CLICK ROOT:

    - Install the latest drivers for LG: https://sourceforge.net/projects/avicohh/files/Android/LGUnitedMobileDriver_S51MAN313AP22_ML_WHQL_Ver_3.13.2.exe/download or drivers LG Verzion: https://sourceforge.net/projects/av...S51MAN313AP22_ML_WHQL_Ver_3.13.2.exe/download

    - Download LG One Click Root 1.3 (Graphic UI): https://sourceforge.net/projects/avicohh/files/Android/LG_One_Click_Root_by_avicohh.exe/download

    - Unzip the archive

    - Enable Usb debugging on your phone . (General > About phone > Software information, tap Build number seven times and then go to Settings > Developer options and turn on Usb debugging)

    - Connect your phone to pc.

    - If the phone not Recognize, try to switch entre MTP and PTP options.

    - Launch LG ONE CLICK ROOT and be guided to the end of the procedure.

    - Once completed you will SUPER SU installed on your device.

    - To check the status of root you can download ROOT CHECKER from the play store.


    - To do this, first download both files (I specify that it is for the H502f) : https://drive.google.com/file/d/0BwmQ3F48xaJjV1lKNUdPQkV2a2M/view

    - And download and install TERMINAL EMULATOR from the play store: https://play.google.com/store/apps/details?id=jackpal.androidterm

    - Copy both files and uboot.img and recovery.img in the root of the internal memory of the phone

    - Go to TERMINAL EMULATOR and run the following commands (after getting the root right):

    dd if=/storage/sdcard0/uboot.img of=/dev/uboot count=1024
    dd if=/storage/sdcard0/recovery.img of=/dev/recovery count=32768
    reboot recovery

    And you're in TWRP and there you can make a backup just to have a little backup in case pending a Custom ROM which I hope will happen soon.

    Thank you.

    I did do that on my test H502f ... but according to some users, it works on the H502g and H500f.

    I'll see if there are other versions

    Are you about to have:
    1- unzip the archive (for both files: uboot.img and recovery.img)?
    2- copied the 2 files .img in root of the internal storage memory of phone (not sd card) ?

    I did unzip the archive in my computer, and then sent the files in my root of the internal storage and the sd card as well. Could you please confirm that the root of the internal storage is the main folder that contains all the files of my phone?
    I am prety sure i have everything done good.... thanks for replying btw

    Well ... as long as you have copied both files to the internal memory AND SD card ... you can try to unlock the bootloader and installing TWRP from the SD card with these commands :

    dd if=/storage/external_SD/uboot.img of=/dev/uboot count=1024
    dd if=/storage/external_SD/recovery.img of=/dev/recovery count=32768
    reboot recovery

    Pay attention with spaces in your shell command
    You have space after dd (in the two lines)
    Another space after .img (in the two lines)
    The third after uboot in the first line
    The forth after recovery in the second line.

    Good luck
