I've patched LGFlashTool.exe to bypass the login screen.

This is for flashing back to stock. It does not flash TWRP or root your device.

Also, if anyone has any other information that needs to be added to this let me know so I can include it.

Thanks for patching this! It'll be valuable for the life of our devices so we are all grateful that you were able to figure it out.

I've used the FlashTool in the past to restore my LG G3. Are we able to flash individual parts of a TOT or KDZ such as a custom recovery without affecting the other parts like /system?

Didn't @tungkick use a custom TOT to root the V10?

For root permission on marshmallow you need a modified kernel which can boot only if the bootloader is unlocked.
In fact the modified tot on the V10 and the modified system.img on the G4 worked only on Lollipop.

On the T-Mobile G5 (H830) we have an unlockable bootloader, however we are unable to flash fastboot commands. Otherwise we would have been the first ones with root in the entire world (we got our phones delivered before almost everyone else).

Can we use this tool to flash a modified kernel?

Edit: for clarification wasn't trying to be annoying or snipe at you; just informing in case you didn't know about our unique situation.

The point is, the H830's "unlockable" bootloader is really "unlockable"? If commands don't work maybe the bootloader is still locked, even if it reports "unlocked"

You might very well be correct in that we have a "fake" unlockable bootloader. However, when Team Codefire released their video showing Root/TWRP they did so with a T-Mobile G5 leading me to think that they were using an unlocked device. I could be totally wrong but seems like not a stretch that they used that device for that reason.

Is it conceptually possible to use the tool to achieve root. I do not have the expertise or knowledge to know if that's even a possibility.

I think that team codefire's method don't use the "fake" unlockable bootloader, but maybe some types of exploit like on G2 and G3

Will this work for the LS992 (sprint) ?
Or will we need a special dll like we needed for the G3 think it was like two files Mega lOck and the device spesific dll?

thanks

LG Flash 2.0.1.6 Installer Repack

Repacked LG's original installer with @ieatacid's patched EXE.

Should make installing it all even easier... no more EXE switch.. just install and use (hopefully).
I made sure to add ieatacid's name, paypal and this thread in the Setup EXE.. this way ieatacid's name will always be attached to the LG Flash install rather than the loose LGFlash.exe getting passed around like the old megalock.dll.

Added LGUP and LG Flash directions and downloads to my All-in-One G5 Thread here.
