I have updated my old script to root ZVB as well as ZVA. This should solve issues that some people were having.

Just extract the zip file, run the .bat file and follow the instructions. Should be pretty simple. Let me know if you run into any problems.

Note: If you are having issues with the script hanging try unplugging your phone and plugging it back in. That should help.

Prerequisites:
Code:
adb debugging
LG drivers
Diag mode enabled ##diag (makes things easier but you can do without it, eg. manual reboots.)

I have yet to be able to root my G3. The files get pushed over to the device but after reboot I have to manually boot it into download mode but then the device never gets recognized by the script.. I am running Windows 10 and wonder if that could have an effect on how the LG drivers work??

Yeah you might need to update your drivers in device manager once in download mode (searching automatically for the best driver should do the trick)

On line 27 in the bat file, change
Code:
adb reboot
to
Code:
adb reboot download
.
That worked for me.

Tried on Windows 10 and Windows 7 machines, After I manually put my phone into download mode (will not go into download mode automatically) the script detects my phone and I get "Author : blog.lvu.kr
SPECIAL COMMAND : ENTER, LEAVE
#"

Then the script just stops with nothing else happening, I've let it sit for 30 minutes thinking it was doing something but nothing. Any suggestions on what to do. My phone and sd card are encrypted, could this be causing the issue?

Yes an encrypted phone/sdcard is probably the issue.

Sorry for the nooby question, but will autorec work after using this to root ZVB? I'm about to get a new device through insurance and world hate to only have root and not custom recovery.

no autorec doesn't work.. but you can use twrp manager (free on google play) or flashimg.

Oh wow, had no idea twrp manager supported this device now. That makes things so much easier. Cause I just ordered my new device today and it'll probably come stock with ZVB. Thanks for the info, really thought id be doomed to stock for a minute there.

So when I run the bat file, it just says waiting for device, but my device is plugged in and I know the drivers are installed, even installed them again to be sure and still nothing, and advice?

This method worked for me, thanks!!! @l33tlinuxh4x0r your the man, thanks for sharing your knowledge with the community and helping others. After trying several other root methods and having none of them work this root method actually worked! I have a LGLS990 LG G3 32GB SPRINT Shine Gold Smartphone. Goodbye Sprint / LG bloatwear and hello new xda gear!

One tip I can give is towards the end you need to unplug the USB cable, power off your phone and manually go into download mode again. The script doesn't prompt you to do that action but I figured it out when I kept getting stuck at around 90%. After I put my phone into download mode manually and reconnected the USB the root completed and SuperSU was installed. I am now running CloudyG3_2.5 and it's working flawlessly, thanks again.

    I've been searching for a straightforward tutorial/instruction on rooting the LS990 ZVI, but no joy.

    I was wondering if anyone has been successful with a particular tool or at least a straightforward downgrade.

    Thanks in advance!

    Successful with ZVE version, with tweak

    I just rooted a G3 with VZE version software. I tried a couple times and the process hung at the second place where it looks for the serial port. Per the suggestion of one of the posts earlier in this thread, I manually booted into download mode by turning off the phone, holding the volume up key and plugging in the USB cable. I followed the prompts from there and it completed the root. Thank you very much!
