How to update LG Leon H340N to Android M and Unlock the Bootloader

[martinsgo]

Witch version did you use? Has the oem unlock for the bootloader?
Thanks.

I use the version posted here, and yes has the unlock bootloader option, now we have to find the way for root

Great! I'm gonna try it then.
I already got root using kingroot and then used This Guide to replace it with supersu.

Can anyone tell me if this will work on my H340F V10A?

Update: Yes, it works.

Any Root method available on mm?

I have another Question: I need to take back the original 5.0 Stock rom, but, what is the Right factory rom file for an unlocked LG Leon H340n?

The latest v10 file available for your country

Is this a cruel joke by the OP or lg: With the old lollipop firmware I could enter the bootloader, but the unlock command was missing. With this firmware, I can "enable oem unlock", but not actually enter the bootloader?

How does one enter that supposedly unlocked bootloader, and which commands does it allow?

Witch firmware version has unlock bootloader option and can be downloaded?

Thanks in advance

Successfull updated to Android 6.0. But Kingroot (v. 4.9.5) can't rooted my device.
It's locked to T-mobile, can't unlocked bootloader. How do you rooted it with Kingroot?

How can i use the LG flashtool to flash the stock 5.0 rom ? ( Because, i don't need that sh.t 6.0 rom, because is too sh.t for me.

Are there any roms for this specific model?

I've installed android 6 since it first got a version into my country and i got bored of it.
I've also searched the internet for roms for this specific model and nothing.

solução

I am getting this message every time I reboot what is that and what must I do to not see this
My LG Leon is H340N (TIM Version) Italy

I'm gonna test it on both my h345 and ms345.

did it work on the ms345?

 

[ricbaez]

did it work on the ms345?

Do not try it on H345 or MS345, you will brick your phone

 

[ninjasinabag]

did it work on the ms345?

It will not work on the american models. A brick is to be expected (not a soft brick either)
I had to replace the motherboard on my ms345 and my h345 is still busted. H345 ends up with an error involving the onboard memory, and I'm guessing the ms345 had the same issue in the end. (H345 still boots to the recovery, but it will not respond once inside the yes or no prompt screen)

help i can't get access root LG H340N

I have a lg leon(lgh340ar) and did the steps described in the tutorial-->

http://forum.xda-developers.com/leon/how-to/how-to-update-lg-leon-h340n-to-android-t3393648

. Everything went well except I can not get root access in any way. there is a way to do that is to access the fastboot menu, try it with the volume down button and the power button and appears only option is to reset the device manufactures and nothing else. Please help me. Thank you.
