Oh yeah? It's been a while. I haven't had to use any of those tools yet but probably soon will once i get to some LG's here. So far doing these ZTE and HUAWEI phones. Sucks too because of their age. It's hard to find working links for anything. I end up having to scour the whole web for recoveries for example.

It will be worth it in the end though. Already seling them for as much as $50 fully rooted/recovery/rom'd + apps. 42 phones to go now, lmao. I'm spending more time on these phones than anything lately.

Yeah i figured some would have something malicious. I have not ran all of them yet. I usually sandbox everything new like that. I'll quarantine them and remove the nasties so they are still usable. Some of that stuff is hard to find.

Speaking of nasties, i've still got remnants of some chrome google updater based adware installer on here that taskeng.exe trys to execute random batch files on and off throughout the day. Already got rid of the main parts so the batch files are non existant. They aren't getting created so nothing gets executed and ran. But something is still generating the google update files which i need to kill here when i get time. Then totally remove Chrome and all remnants of it and google updater / reinstall and import all my bookmarks and settings back in.

This phone laptop is probably my next to sell anyway so ill probably just back up the files / bookmarks and wipe everything. Thought about eliminating the virus then removing our private tools and leaving the rest of the mainstream phone apps, rooting apps, qpst etc and selling it as a phone repair laptop but doubt i would have many people interested.

Anywho im getting off topic!

GL with the Zone 3 stuff and that ZTE Max Pro. I worked on one of those Max Pro's for a client a while back. Wasn't too hard of a job.

<DISCLAIMER>
Hi Android users!
My name is Astr4y4L of Team Astr4y4L.
We are New to Androidforums but not new to android.
Here back a few months ,we've discovered a fool-proof method to root the Verizon Zone3.

< A bit of History >
Basically long story shortened, we first rooted the device by downgradeing the current firmware version to a version known to be rooted by king root ( we call this PP2 for short) It was the second version of the software (vs425pp2) .

we could accomplish this by using lg's firmware upgrade tool called Lgup.

After flashing the PP2 .kdz firmware from lg , we could then download or sideload kingroot 4.8 and root the phone using the one-click.

This however was a long process because between ( vs425pp2 ) and (vs425pp4) they changed somethings in the modem firmware and as such ,
after downgrading the firmware, it would bootloop 10-100 times before finally booting up.
and bootloop again every time you rebooted it.

but we finally by trial and error , narrowed it down to modem firmware , and we downloaded the stock kdz of vs425pp7 and used some python tools and scripts to extract the firmware and get the raw partition images. we converted those into .img files and used our new root access and a wonderful root tool called Partitions Backup by Wanam to replace the modem partitions on the device with those we prepared from firmware.
at that point we rebooted and it never bootlooped again. Yeah!!!

After that we made two Kits:
The first kit,
gives you all the tools you need to root your device from the device it's self.
that is detailed here.

Our second Kit ,
involves flashing Pre-rooted firmware to the devices using special Modified Tools
And as such We've chosen not to disclose that Here , And Politely Will not be answering questions about that here.

But there are a few things you should know first.
This has a potential to brick your device if done wrong.
This has proven Not to work for the devices that came with (Vs425pp5 ) because of graphics driver issue.
[***There is a Different way to root PP5 And all other devices that get screen issues on Downgrade.
scroll down after the main part of this Tutorial.]

we've put together a little kit to help you accomplish this all with out having to start from scratch .
and another little kit with the correct firmwares and the Lg tools Lgup etc,


SO On with it right?

TAKENOTE: CHARGE YOUR BATTERY FIRST

[PLEASE DO NOT MIRROR THESE FILES]
and patience.

here's our write up on it (also included in the zips)

[EDIT:] Added The Steps to DownGrade

Part 1:###The Downgrade to Exploitable firmware###

In this part of the guide we will cover how to downgrade your device to exploit it with kingroot

<IMPORTANT>
IF YOUR DEVICE IS VS425PP5 OR IF YOU GET BLACK AND WHITE LINES ON SCREEN AFTER DOWNGRADING TO PP2 ,THIS WILL NOT WORK FOR YOU YOU'LL HAVE TO USE ANOTHER METHOD, ONE IS AVAILABLE BUT WILL NOT BE DISCUSSED HERE.

STEP 1: The first thing you need to do is download the correct firmware drivers and tools to downgrade the Zone3 device.

My Real Good Friend @MotoJunkie01 over at XDA has set up a google-drive folder with everything we need and has given me permissions to share it with you here. Thanks @MotoJunkie01 !!!
EDIT:
two links listed above contain the files and programs
once you've downloaded the necessary files
place them somewhere convenient and
We're all covered.
So first visit the above link and download the following

<DOWNLOAD THESE>

LGMobileDriver_WHQL_Ver_4.0.4.exe <--- INSTALLS DRIVERS FOR PHONE
LGUP_Install_Ver_1_14_3.msi <--- INSTALLS LGUP
LGUP_VS425PP.msi <---installs the Common .dll for our phone in lgup(INSTALL LGUP_INSTALLER FIRST)
PP2.KDZ <--- THE FIRMWARE TO DOWNGRADE TO (VS425PP2)
PP7.KDZ OR PP8.KDZ <----- THE FIRMWARE TO FLASH BACK IN-CASE ANYTHING GO'S WRONG !!!!

Step 2 Prepare the P.C
Now we get the P.c ready to downgrade, first install the three installers downloaded above.

NOTE: Order of Operation is important Here. Notice the order they are in in the list I've provided above, you should also install them in that order as they are dependent upon each other.

STEP 3:
Once we have all the drivers and tools installed
Launch LGuP by right-clicking the Desktop Short-Cut and choosing Run-As-Administrator.

Lgup Should pop up a box saying Nothings connected , Click ok
now your left with another box that looks like an empty list.

NOTE: YOURS SHOULD NOT SAY UNKNOWN OR HAVE ANYTHING IN THE MODEL BOX YET. PICTURE FOR REFERENCE

Now Put your device into Download mode.
The device MUST BE POWERED OFF TO GET INTO DOWNLOAD MODE,
This is accomplished by holding +Volume while connecting your micro USB cable for your PC connection. WITH THE DEVICE POWERED OFF (NOTE: this ONLY works with USB 2.0 DO-NOT use 3.0 )
Your Device Should Boot up Saying DownLoad Mode And LguP should see it in that little box.

IT SHOULD SAY UNDER MODEL VS425PP SOMETHING


if it's got something written in the box now and Highlighted kind of a Pink color, then Lgup see's your device.
It should say MODEL: Vs425PP(some-version) Comsome-number)

Click OK in the box, Now LguP will open to flash , upgrade ,downgrade etc. your device.

Now you'll see some options with little dot-style buttons to choose from.
<PLEASE NOTE THAT YOUR VERSION ON THE PICTURE WILL SAY SOMETHING>
< DIFFERENT THIS PICTURE IS FOR LGUP REFERENCE ONLY>

Choose Refurbish
a little further down is a line that reads
BIN FILE Click that and you'll notice
it has three little dots at the far right of that line in the box.
click those three dots and it will open another box to allow you to choose your .kdz firmware to flash...
SO navigate with the box to where you've downloaded PP2.kdz and select it.

after selecting the firmware it go's back to main screen,
Click Start and watch the magic....

After you finish flashing it'll look like you killed your Phone ,LOL
because it will boot-loop constantly showing the recovery android thingy but will eventually boot up fully ---Just WAIT FOR IT !!!!!

after the bootloops you will be booted into a PP2 system and ready to follow the rest of this guide...


####################################################
PART 2 Exploit the device and restore radio firmware to stop bootloops
####################################################
This assumes you've already followed the above method to downgrade to pp2 firmware by manually flashing a stock firmware.kdz using LGuP and Have working Android Device Bridge on your pc and have enabled it in your device options/settings menu


DISCLAIMER:AGAIN:

I NOR ANYONE ELSE IS RESPONSIBLE FOR ANYTHING THAT YOU CHOOSE TO DO WITH YOUR DEVICE........

THAT SAID LETS BEGIN.

step 1:

download and unzip to desktop Team_Astr4y4L's Legacy_zone3_root_kit
same link from above


from the unzipped folder open terminal : open CMD window here ( ctrl+shift+right-click )

and type

Code:

adb install "kingroot4-8-0.apk"

adb install "XposedInstaller_by_dvdandroid_29_04_17.apk"

adb install "Partitions_tool.apk"

step 2:

run kingroot to get root access.

***someusers report kingroot requires many reboots. So be patient.

then open xposed installer {grant root} and use the option in 3dot menu [top-right] to fast-reboot

step 3 : now in terminal : open CMD window ( ctrl+shift+right-click )

Code:

adb push "mrw" "/data/local/tmp/mrw"

adb shell "chmod 0777 -R /data/local/tmp/*"

now open "mrw" on desktop, open root.sh in Wordpad select all copying and pasting into root terminal

at the end you should have supersu and be rid of kingroot..

exit terminal

Code:

exit
exit
exit

step 4:

let supersu update binaries then DO NOT CLICK REBOOT

Use Xposed installer to Fast-reboot again

step 5 :

open partitions tool and back up these partitions

fsg, modem, modemst1, modemst2, ssd

let it do its thing....

step 5:

now back on pc at terminal...

Code:

adb shell

su

mv "/storage/emulated/0/PartitionsBackups " "/storage/emulated/0/PartitionsBackups .bak"

exit

exit

adb push "PartitionsBackups" "/storage/emulated/0/PartitionsBackups "

step 6:

back on the phone open Partition tool again and use the 3dot menu {top right corner} to choose restore partition.

navigate to the sdcard/PartitionsBackups folder "not the one with .bak at end"

and choose backups to restore in this order,

modem, modemst1, modemst2, fsg, ssd

Note :these are not the backups you created these are the .img files I created to replace them...

now that you've done that exit all apps unplug from pc and use powerkey to reboot naturally,

enjoy root with out bootloops

GoodLuck, and happy Rooting,

Blind Root for LG Optimus Zone 3 with TalkBack.

Suggested Prerequisites:

A windows computer
A USB data cable
A pair of ear buds – not necessary but the in phone speaker is a little quiet
Screenshots of menu screens
Familiarity with Talk Back
One or two dry runs with a working display before you boot to PP2
Vysor APK or some other screen mirroring software


What is TalkBack?

TalkBack is the Google screen reader included on Android devices. TalkBack gives you spoken feedback so that you can use your device without looking at the screen.

https://support.google.com/accessibility/android/answer/6283677?hl=en


Directions

Complete the root tutorial up to the point of booting into a PP2 system. Your phone display will be useless but touch input works. It’s hard to tell when the device is done boot looping so it may help to keep LGUP open to see when the device is done bootlooping.

Once booted, press and hold two fingers on the display. You should hear the Talk Back voice tell you to continue holding two fingers until you hear a beep to enable talkback.

Once Talk Back is enabled it will walk you through a tutorial. If you memorized where the next button is you can skip some parts of the tutorial. If you can’t find next, just continue with the tutorial until the end.

Talk Back has a lot of gestures that I never bothered to understand. Here are the basics:

Swipe left to right to move forward to the next item on the screen.

Swipe right to left to go back.

Talk Back will tell you what item is currently selected. Double tap to register a click on the screen.

Sometimes Talk Back will not let you double tap to click. Try going back and forward again to get it to let you double tap.

If you do a single tap on the screen it will select whatever is on the screen. If you have a general idea of where an icon is, you can click and select it. You must always double tap to actually interact with the icon or menu.

Go through the initial phone setup. The Back, Home, and Menu buttons will be disabled during setup. On the bottom right there is usually a skip or next button. I suggest skipping everything, including Wifi. Entering text on the Talk Back keyboard is frustrating.

If you have to enter text, imagine the keyboard is exactly like you see on a working display. Press and hold with one finger, then move around while Talkback tells you which keys you are selecting. Release your finger to type the key that was just announced.

After you get through the initial phone setup:

Navigate to Settings > About Phone > Software info > Build number

You would normally tap 7 times to enable Developer options, but with Talk back its 14.

Talkback never announced that I had enabled developer options, but that may have been because I was just spamming the clicks and was interrupting the voice navigation.

Navigate back to settings and there should be a new option for Developer options.

In Developer options, enable USB debugging. Remember, you can’t enable USB debugging with the phone connected to the computer. Unplug the usb cable to be able to turn on USB debugging.

From a CMD prompt, type ADB devices to confirm you can see the device. The first time you use ADB you will get a prompt on the phone to allow the connection. You have to allow the connection to use ADB.

I recommend checking the box on the phone to always allow connections from this computer.

Next, Navigate back to settings > Security > Unknown Sources and check the box to allow.

Now in the CMD prompt, install Vysor or your choice of Mirroring software APK. If you have the APK in the folder where you opened the CMD prompt, the command would look something like this:

ADB install “com.koushikdutta.vysor_1.0.1.1-1521579600_minAPI16(nodpi)_apkmirror.com.apk”

Download the chrome plugin or full install for Vysor. Vysor should automatically detect your device. Click view and it should mirror your device on the computer. From there, navigate the phone using your mouse.

Vysor has ads every time it starts and every 30 minutes. You can usually close or skip the ads after 5 seconds.

The Vysor display gets very blurry with low resolution occasionally. Waiting a few seconds usually clears this up.

Occasionally Vysor could not see or connect my device. Running adb devices from a command prompt usually cause adb to restart the daemon which allowed Vysor to see the device. Sometimes it takes a minute for Vysor to respond.

At some point after rooting with Kingroot I could no longer get Vysor to connect to the device. Closing Vysor on the computer and opening it again corrected this.

Once Vysor is working and you are comfortable using a mouse to navigate, proceed with the rest of the root tutorial up to the point where you restore partitions. After restoring these:

modem
modemst1
modemst2
fsg
ssd

At this point I rebooted the device to confirm it did not boot loop. You can probably skip rebooting but thats up to you.

Now restore all of the partitions from the PP7 boot-chain one by one. I did it in this order but I don’t know if that is necessary:

aboot
abootbak
boot
laf
rct
sbl1
sbl1bak
tz
tzbak
Once completed close everything, reboot and the screen should be working on a rooted device!!
