[LS990] ZVA/ZVB/ZVC "One Click" Root Method

[aheeejd]

OMG, I have root. SuperSU is installed & i just installed RomToolbox Pro, su prompt, grant, boom working app. Now i just need to get twrp on here somehow.

Seriously, I think there really is something about running these type of things more then once. I ran it with usb charging only, switched to mtp or ttp, whatever they are, & once i realized that if this failed no harm to phone was done so i just kept running it. Didn't see the busy box error i was seeing all day, & it finally went through & rooted.

Thanks. Just tried it on LS990 ZVC and it worked.

Wouldn't work for me on ZVC, even with diag enabled - kept saying "Couldn't open COM port".

For anyone having trouble, here's what did work (copy/paste commands, executed using tools from extracted zip in OP:

adb.exe push busybox /data/local/tmp/ && adb.exe push lg_root.sh /data/local/tmp/ && adb.exe push UPDATE-SuperSU-v2.46.zip /data/local/tmp/ && adb.exe push lafzv6.img /data/local/tmp/

(reboot to Download manually)

Send_Command.exe \\.\COMx (x = your serial port - use ports.bat or look in Device Manager)

dd if=/data/local/tmp/lafzv6.img of=/dev/block/platform/msm_sdcc.1/by-name/laf

(unplug, yank battery, then reboot back to Download mode manually)

Send_Command.exe \\.\COMx

sh /data/local/tmp/lg_root.sh dummy 1 /data/local/tmp/UPDATE-SuperSU-v2.46.zip /data/local/tmp/busybox

(Wait for script to run. Then unplug, yank battery, then boot normally).

Boom.

Win 10, ZVC, Lollipop 5.0.1 --> finally, it worked

Finally, it worked on ZVC (LS990ZVC, lge/g3_spr_us/g3:5.0.1/LRX21Y).

I'd tried ioroot, and one-click. Ioroot didn't have the LS990. One-click asks for your email address, and after you supply it, demands $29.95 (or $39.95?).

The LG Root Script has some issues, initially. The batch file says:

1. It works for ZVA and ZVB, with no mention of ZVC.
2. To enable Diag mode, but what is that? Some Internet research says that to enable Diag mode, you must have a rooted device. That makes no sense. After searching in Win 10 Device Manager for a way to enable Diag, I ended up ignoring the batch file on this point.

I tried it, anyway, and it began to look promising, when it successfully pushed 5 files to the phone.

It kept hanging, though, while trying to find the serial port. I'd wait patiently, and eventually it'd say:

Disconnect the USB cable and turn off the phone.
Then press and hold the Volume Up button, and while you're doing that connect the USB cable again.

OK... So, I did that, and it would flash an SU (?) error code of 1003, before directing NOT to disconnect the cable while it downloaded files (or uploaded?). That screen would never change, from 0% downloaded. Why?

Eventually, I found MinceMan's suggestion on page 4 of this thread, to use USB charging mode, and not MTP. That seemed counterintuitive, but ok. You can change that in Android Settings, Storage, and tap on the icon at the top, right.

This didn't seem to help (at first). The results were the same: all of the above issues, culminating in 0% downloading (or uploading, or whatever).

Some other messages along the way:

Phone found at COM3!

Installing LAF this might take a minute or two...

Author : blog.lvu.kr
SPECIAL COMMAND : ENTER, LEAVE

###Please press Ctrl+C, and then type N and ENTER to reboot.?
#^CTerminate batch job (Y/N)? N

Rebooting...

Looking for LG serial port...

The above messages occurred both in the 3 or 4 times when it didn't root, and finally when it did.

At one point, right before it finally worked, I had to ignore the message saying not to disconnect the USB cable. The phone was stuck on that 0% downloaded message, though. I was forced to remove the battery to reboot. Boy, was I worried that a bricked phone was in my future! But it came back up fine, and I tried the LG Root batch file yet again, and this time it finally worked. I'm not really sure what the difference was, but it was the 2nd try after I switched from USB-MTP and into USB-Charge, and the 1st try after the battery removal.

It's a long post, but hopefully it helps someone. Be persistent, but make a backup first (!), then download and install LG drivers, turn on USB debugging, and switch Storage to USB-charge.

Script broke my sensors?

Hi, having eliminated other culprits it seems there's code in this script that's destroyed my phones ability (among other things, no doubt) to rotate the screen, which makes viewing certain websites, videos, and most photos difficult. Once I flash a custom ROM with its own kernel I'm okay, but when I flash back to stock, again, no sensors. Is there a workaround, or some code I could enter myself in a root terminal to fix that?

Thanks!

[Lucien1997]

Awesome

tried on ls990ZVE nd worked like a charm thx.....

 

[gameplayerdo2]

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:

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

Fastboot or download mode? If you are in fastboot then you deleted your laf partition and need to use fastboot to flash the laf partition back to your phone before running the script. Also as a side note I no longer have a G3 so I can no longer test or debug this.

the phone is working fine, but when its going through the process it gets stuck at the fastboot screen and i have to unplug it or pull the battery. but then it starts back like its never missed a beat and at the end it says rooted or whatever but it isnt. and it also says that its installing laf at a point. thanks for getting back with me..

LG Root Script v2.4 the best
ZVC and ZVE rooted is OK ... Many thanks...

 

[Dataventurer]

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!

 

[i0wnurface]

Can also confirm works beautifully on ZVE, Thank you!

Internet not working on lg g3

Hi.
I had bought this LG g3 LS990 unlocked through ebay india to use as cdma phone and the seller had confirmed me that it will work as both cdma as well as gsm. Upon receiving the phone the sprint activation was bugging me again n again hence I tried stopping it and in the process the software got corrupt. Somehow i managed to root the phone again finding from forums online and stop that activation error also. Now the phone works perfectly fine(i am using gsm now) The only problem is that I am unable to use mobile data in it. It works perfectly through wifi. Please help me how to get my mobile internet working.. Thanks.

 

[InternetMayhem]

Works good! Thanks again, I have rooted both my G3 smartphones with this method. This last device that was originally locked with McAfee took some effort but after putting the device manually into download mode it worked the 3rd time! Now the first thing I am doing is removing this McAfee garbage.

Thank you very much

My Freedompop (sprint) LG G3 LS990 ZVF Lollipop 5.0.1 was rooted the first time through.

Been looking for a root that worked for days.

Can I say Thank you very much some more?

Thank you!

 

[pikeca]

Has anyone tried this with ZVF? Thanks in advance.

Edit: Worked great for me. Thanks!

Thank you!

do you know any videos that can guide me with rooting the lg g3 using this method and if not can you tell me if i have to install anything other then the one click root thing, (i know you have to install lg drivers but im unsure of anything else) (also first time going to root my lg g3 with a computer)

 

[avibp]

do you know any videos..........

No videos - Yes Drivers
Here's the best I can offer - Good Luck
I'll try to give you the best instructions as I can.

I downloaded two sets of drivers and installed them both and I can't say which one is correct. My computer selected and I deleted the devices from the Windows 7 Ultimate Device manager more than once and let them reinstall automatically with no choosing/choices of mine.


Install both sets of drivers (below) and then, I 'BELIEVE' that it is important to plug in the phone, allow the drivers to install and as an additional step after the drivers install, turn your phone into Download mode (Power off, hold the volume UP button and then plug in the USB cable). I say this because it installed an additional driver for this mode that I found MUCH later error-ing on my windows 7 in a pop-up (toast) display hidden behind other widows.


Sources for drivers are received from two XDA links

    • https://androidmtk.com/download-lg-usb-drivers . I chose “LG G3 (all variants)”

Then I simply downloaded LG ROOT that the OP also posted in the first post, Unzipped it and ran the BAT file that was inside. The BAT file included instructions (thank god) in the file as it ran.


Sorry for the delay
