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.



Step 2: UNLOCK THE BOOTLOADER and INSTALL TWRP :

- 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):

su
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 2.8.7.1 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.

Hello

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
 
Hello, i have a problem with the installation of twrp and unlocking the bootloader. When i type the command "dd if=/storage/sdcard0/uboot.img of=/dev/uboot count=1024" in the emulator, it says, no such file or directory :( please help
 
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
 
is there an alternative way i can do it? ive searched about it on the web but there is not something clear about lg magna
 
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 :

su
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
 
thank you very much! i actualy did it, i followed some insturctions of a guy in xda develpores and they helped a lot.
