WORKING ROOT | T-Mobile LG Leon 5.1.1 Lollipop - LG Leon Guides, News, & Discussion

{WORKING ROOT FOR T-MOBILE LG LEON LTE 5.1.1 LOLLIPOP}
.....so after a week & some change of endless searching for a working root method, following tons of half-assed directions, trying about 4-5 "1-click root scripts" and installing a bunch of different root APK's with absolutely no luck I finally successfully rooted the T-Mobile LG Leon 5.1.1 Lollipop by putting together a few things I found on this forum.....
This method (with files linked to this post) ONLY works on the T-Mobile LG Leon LTE 5.1.1 Lollipop by downgrading to the previous 5.1.1 Lollipop firmware before the current version.....I did not try it on the MetroPCS variant so please do not inbox me asking "hey bro does this work on MetroPCS??" because I do not know.
It will more-than-likely work if you follow the instructions but you'll need the MetroPCS firmware .kdz file, not the one linked to this post...just find the file and follow the instructions below.
You need the following;
T-Mobile LG Leon Drivers-----> Windows | MAC
LG Flash Tool 2014-------------> LG Flash Tool 2014
LG Leon H34510d kdz file-----> H34510d kdz file
Kingroot 4.5---------------------> Kingroot 4.5
Once you've downloaded the above files follow these directions to successfully root your LG Leon from T-Mobile.
*********************************************************
~BACKUP WHATEVER YOU DO NOT WANT LOST~
~This method will wipe all your apps, pictures, etc.~
*********************************************************
|[ INSTRUCTIONS]|
1.) Download & extract above files to desktop.
2.) Put device in download mode by powering off completely. Then, while the phone is still off, hold the "volume up" button for 2-3 seconds and insert the USB wire (make sure the USB is connected to your desktop/laptop) until download mode screen appears.
3.) Run LG Flash Tool 2014
4.) Once the LG Flash Tool is open, leave (or select) "Select Type" As "CDMA".
5.) Change "PhoneMode" to "CS_EMERGENCY".
6.) Click the folder icon to browse your computer and select the "H34510d_00.kdz" file.
7.) Click the button that says "CSE Flash".
8.) Click on the Start button.
9.) Click on "Clear Update Registry".
10.) For "Country" select "Different Country"
11.) For "Language" select "English" (or whatever language you use).
12.) Click "Okay" and let the LG Flash Tool recognize your device. The Flash Tool will do it's thing and load the file onto your device...it takes a minute or two so just let the process run it's course. Once it hits 100% your phone will reboot once or twice- leave it plugged in -you will see the Android with the spinning blue "thing" in his belly for a second or two then the device will reboot. Wait until the Flash Tool progress bar is at 100% on your computer and your phone shows the setup page (like when you turn it on the very first time) and unplug the device.
***Once the downgrade starts you may see a popup window that says something like "Can not connect to servers" but it is just an error...you can see the timer & progress bar running behind the popup, just ignore it.***
You are now downgraded to the 10d firmware {H34510d}.
13.) Install Kingroot 4.5 and run that and it will take about 30-60 seconds to acheive root.
###ENJOY ROOT ACCESS###
If, for some wild, crazy reason this fails and you soft-brick your device (which shouldn't happen if you follow the directions) check this thread to unbrick: Unbrick T-Mobile LG Leon
Thanks to Yazuken1 and IPRJ25 for some of the info that helped me put this together.

I used this exact same process, except for the Kingroot step. For that step, I used this guide - http://forum.xda-developers.com/android/development/guide-how-to-root-lgls770-5-1-1-t3184649. It takes longer than Kingroot, but it might be useful to have that documented here.

I just used Kingroot 4.5 because it was the first to pop up on the returned search links...when I previously installed Kingroot (4.1 I believe) it said there was nothing for the device it was installed on but that may be because I didn't downgrade yet...

Thanks.

Seconded! That script is supposed to be able to root the newer 'e' and 'f' roms according to the post, but I can't register! I've been trying for over a week to get a dang Android Forums account, but the signup process seems broken right now and emails to the site admins have gone unanswered. All I need is that silly script and it's really aggravating

Kdz error!
I am having a problem. The kdz file will not work says no file when trying to download. Can anyone help me or email me the h34510D Is a file please! Or is there another kdz I can use for a successful root? I have tried changing the urls devtester suggested as well. [email protected]

I had the LG Leon a while ago and I have rooted it with Kingroot 4.1 and replaced kinguser with Supersu using SupersuMe Pro 9.1.2 (other versions didn't work, they hangs on the phase 1). I don't share my apk since it is a paid app. But I still recommend using Supersu rather than kinguser as it is more compatible with a lot of root apps (e.g. Titanium Backup tells you that you MAY have some problems with it, Busybox by Stericsson doesn't work telling you that you are not rooted ecc.) But there is still a little workaround if you don't want to use SupersuMe (and of course it's free ): when you have kinguser install this: https://play.google.com/store/apps/details?id=com.bitcubate.root.busybox.complete&hl=it , (it's mandatory for Flashfire to run) install Busybox within the app and then install Flashfire and with the app flash the Supersu.zip . Flashfire says that it isn't tested on this device but I flashed Xposed, Titanium Backup system zip and Dolby Atmos on mine. Only thing I noticed that restoring the backup of Flashfire simply doesn't work (idk why). But for sure it flashes zips with no problems.

Missing 10D kdz
It looks like the 10D kdz file is no longer available from the original link. I have looked extensively for a copy to no avail.
Does anyone have a local copy they can post ?
Thanks !
