$25 From Me

for the person who roots it. I paid a similar bounty to root the T-MO LG G5 and it's definitely worth it to me.

I don't own this tablet but I see its on 6.0.1. I believe T-Mobile version has unlocked bootloader so recovery needs to be built..Thats the only way of rooting mm.

The bootloader can be unlocked as described in the main thread. However, could you please provide more details about rooting with recovery?

He was talking about compiling recovery first and then root using TWRP by flashing supersu in TWRP.
To make a twrp recovery, from what I know, devs need system dump. A kdz file is better but shouldn't be mandatory.
Since our bootloader is already unlocked/unlockable, we just need to wait for some devs who know how to compile recovery and are interested in our device with free time to compile TWRP recovery using system dump.

You need root *BEFORE* you can even install TWRP, locked bootloader or unlocked bootloader doesn't matter. You have to find a way to root it in the first place.

What you said is not true. Neither is a prerequisite for the other. For some devices, they get twrp first and then use twrp to root, while for other devices, they get root first and it's easy to install twrp with root and unlocked bootloader.

I have the VS985 G3 and VK810 G Pad 8.3 currently.

Maybe that's true but I haven't personally come across an LG device that you can flash a custom partition without having root first. I've only seen that on Samsung when you could Odin a custom recovery tar. Without root, you don't have permissions to flash over top of your stock recovery. And if you can put TWRP on without having root you certainly still need to come up with some kind of vulnerability for the device, whether it's root or something else, in order to get around the stock protections that keep us from installing and using a custom recovery.

In the case of both LG devices I have, you need to have root and a bump-vulnerable bootloader to install TWRP. I'd like to know so I can be aware: what devices can you put TWRP on before discovering a root vulnerability?

All devices that have MM out of the box need to unlock bootloader and flash recovery first! There is no such explocit that allows you to root MM! Thats why Chainfire made SYSTEMLESS ROOT FOR MM, which basically places root in boot.img, in MM system cannot be touched. Hence recovery is mandatory to root MM which this device came with, its not G Pad 8.3, you cannot downgrade to KitKat bootloader as it doesn't exist! BUT as its from T-Mobile they bootloader IS UNLOCKED out of the box, do if someone builds recovery you can simply flash it in fastboot. Devices that require recovery are G4, G5, OnePluses, Nexuses, Sony devices and many many more.

Ah, sorry, didn't realize T-Mobile bootloaders are unlocked out of the box, my bad.

Here I had thought all devices had a locked bootloader these days, especially out of the box Marshmallow ones.
