Downloading LG Firmware the Simple Way!

I don't see why all this faffing about with proxy grabbers and URL guessing in necessary to get the correct firmware file for your LG phone, there is an easier way...
1. Go to the LG website and find your phone, download the USB drivers and mobile support tool.
2. Install the USB drivers, remove the battery from your phone and note the model number, serial number and IMEI number then replace the battery.
3. Turn on your phone and plug in your USB to the computer and phone and wait for the drivers to install.
4. Click your 'start menu' and select 'Computer', click the 'Tools' menu at the top left of the screen and select 'Folder Options' and then the 'View' tab, put the radio dot in the 'Show hidden files, folders or drives', also remove the check-mark from 'Hide extensions for known file types' and click 'Apply' then 'OK'.
5. Run the mobile support tool 'exe or setup' file, select the emergency firmware recovery thingy and enter your phones I.D from earlier
When the mobile support tool finds your firmware download, click to download it.
6. Immediatly navigate to 'C:\ProgramData\LGMOBILEAX\Phone\' where you will find your firmware file in the process of downloading (mine was called 'V10A_00.kdz').
7. Keep an eye on the mobile support tool to see when the download is going to complete, before it does right click on the white background of the 'C:\ProgramData\LGMOBILEAX\Phone\' folder and select 'Refresh' to update the firmware files downloaded file size - ideally do this several times during the download process to allow Windows to calculate the file size faster at the end and produce a useable '.KDZ' firmware file before the mobile support tool get's too far into the process of extracting it.
8. Once the mobile support tool changes from the downloading screen to the flashing part grab your firmware file and drag it to the desktop or any other location to copy it, you only have a small amount of time to do this before the mobile support tool extracts the files and deletes the '.KDZ' file so don't worry about scratching your arse just yet!
Just a note, I also copied the extracted '.CAB' file and 'DIAGCommand.xml' files for no real reason!
9. Once Windows has copied it and the 'File Copy' box closes YANK THE USB LEAD OUT OF YOUR PHONE!
If for any reason your computer takes longer than 10 seconds after the download finishes to copy the file then pull your USB lead if you don't want the phone updated and go buy yourself a decent computer!
If you wait any longer than 10 seconds after the download completes you may well brick your phone which I'd like to add I accept NO responsibility for, not even if you follow my method to the letter and still end up bricking your phone I promise you I won't lose a moments sleep over it!
What I can tell you is that the 10 seconds time frame I give is an over safe time frame. In reality your phone will not start to flash any data until it reboots so I suggest having the volume turned up to listen for the USB disconnect / reconnect sound. At the very latest remove the USB cable after the disconnect sound but if you hear the reconnect and the cable is still attached you have 2 choices, 1: Do nothing and have an updated mobile phone or 2: Pull out the USB cable and have no phone. YOU HAVE BEEN WARNED!
Hope this helps you. Please 'Thank Me' if it does.

First off im sorry for quoting op. Im try said method to get a kdz thats not released. As soon as im using old mobile support tool btw. But as soon as dl hits 100 tool attempts to extract it and imeaditly deletes its no 10 seconds. Literally like 1/2 second the goes to error. Long story short. I got a old lg vista frp locked and no available method to bypass i was gonna attempt to update it to a newer firmware to see if ne of the methods work there. The phone was released with kk and not really a antirollback protection. But theres a speci proced to downgrade and i figured if i could get back kk no frp

the method seems to work, so thank you for this solution, i tried a few times until I made it happen, the thing with this is that you can only get recent updates, and in my case I'm looking for an older version of the firmware. hope your post will be usefull to other. thank you.

[GUIDE] Crash Course in ADB/Unlocking on WINDOWS

Just wanted to try and put together something helpful for those who are unlocking their devices who might be doing this for the first time or just are having issues.
THIS GUIDE ONLY WORKS FOR WINDOWS FOLK, SORRY! IF YOU HAPPEN TO BREAK YOUR DEVICE OR DO ANYTHING TO IT THAT PREVENTS YOU FROM USING, I AM NOT RESPONSIBLE, CAVETE LIBERUM OPUS.
ADB
Download ADB from here: http://developer.android.com/sdk/index.html
Make sure you install it where ever you are comfortable with, I tend to keep mine in my main installation (C: )
HTC Sync
Download HTC Sync here - http://www.htc.com/www/software/htc-sync-manager/
Why download HTC Sync? For the drivers. After the installation is complete you can remove HTC Sync, just not the drivers.
Appropriate Drivers
In your Program Files (x86) folder, there should be an HTC Folder, with the drivers in it.
What you are going to need to do is make sure that your device has the HTC drivers installed.
You'll need to open Control Panel ----> Hardware and Sound ----> Device Manager
Your HTC One should be under portable device or android phone, or something similar to that. If it is telling you the current drivers are up to date, you may need to disable driver signature enforcement, and that method is different between Windows 7 and 8.
You'll want to update the driver software by right clicking ----> Update Driver Software ----> Browse my computer for driver software ----> Browse...; then select the HTC Driver folder from within the HTC folder (you'll have to navigate to it)
If you need to disable driver signature:
Windows 7 - http://bit.ly/1bE0jZT
Windows 8 - http://bit.ly/1bE0mF7
Trouble Shooting ADB and Rumrunner
I am, in no way, saying that I am an expert in running rumrunner. If you can use irc and contact beaups please do. However, just in general, here are tips I think might work -
Go to "System and Security" from Control Panel and click "Allow an app through Windows Firewall." Click "Change Settings" at the top and then click "Allow another app...". Navigate to your extracted rumrunner file and select the soju.exe to be allowed through. Why do this? Because I personally rather not take down my entire firewall to allow this program to run. No offense to beaups, just doesn't seem terribly practical to me.
In your ADB installation folder, go into SDK -----> platform tools ----> Hold down left shift and right click -----> Open command window here
type in adb devices; if you are not seeing
List of devices attached
XXXXXXXXXXXXXXXXXX device (read the X's as a string of numbers which are your device)
then it isn't ready to be use rumrunner. You'll have to go into Settings -----> About Phone -----> Software Information -----> Then click 7 times on Build Number to unlock developer options. Go into "Developer Options" and enable USB Debugging.
As mentioned in Rumrunner, please run soju.exe AS ADMINISTRATOR, to avoid permission issues on computer-side.
OEM Cables are also ideal in this situation. Also make sure you downloaded the right file (.8 version versus .10)
Last but not least, IT TAKES A WHILE FOR SOJU TO RUN. BE PATIENT Your phone will reboot A LOT during the entire process. It'll take awhile, but if you run into the (.........) problems or an error because your drivers aren't installed correctly be patient.
The guide isn't perfect, but hopefully it helps. I'll add advice if it comes in.

Great guide!
Make sure to remember to do a fastboot devices check too. that is my problem adb works great fastboot is another story

How to Root LG-VS410PP (LG Optimus Zone)

I rooted my LG Zone from verizon and would like to share with you guys how exactly I did it. It took some trial&error but I eventually got it. First off you're going to need the following
Windows 7 Operating System
Usb Cord
Rooting toolbox
Universal ABD Driver
Due to the fact that I'm new I apparently can't insert links, so as much as i want to I cannot lead you directly to your materials. First google how to root lg zone. You'll run into another xda forum by the user thepcmrtim. He talks about how he took 3 weeks to root the phone. He'll give you the dropbox link with the toolbox.
The dropbox file is safe to save to your computer. Inside the zip file(which you should unzip) you will find instructions that were not written by me. You can either follow that persons instructions or you can follow mine. But the instructions aren't completely useless. You will also find Super One Click (You will need this) folder, and universal ABD driver master (You don't really need this). As for the Universal ABD Driver, open the instructions document using wordpad or Microsoft Word and you will find a github link. Follow the link using your favorite browser and you want to scroll down and download the windows installer one. It'll install everything for you. Once again, its all safe to download.
By now you should have everything you need to root your lg Zone! Lets get down to business.
Step One. Open the .msi (installer) file for Universal ADB Driver. Install that. Once its installed, open "computer<local disk(mine is named that, idk about yours. Its usually drive C)<Program Files<ClockworkMod<Universal ABD Driver<usb_driver
Step Two. for the less tech savvy this is where the coding comes into play. Nothing heavy just a little copy and paste. For those with a little experience this will be a walk in the park. Open the android_winusb setup information file in notepad. Scroll down to the LG section, and underneath the last %LG% thingy, press enter and paste in the following two lines.
%LG% = USB_Install, USB\VID_1004&PID_6244
%LG% = USB_Install, USB\VID_1004&PID_6244&MI_04
Then press save. If access is denied open notepad as administrator, set the filter to All Documents(Or files, i don't know from the top of my head), and go to the usb_driver folder. Open android_winusb stepup information file. Repeat the step above, and save.
Step three. Now you want to check and make sure your phone's driver is installed on the computer. For those "who ain't got time for that" skip this step. Its merely a precaution. Now you can usually tell if your phone's driver is installed on the computer if you can access your sd card on the computer by connecting your phone via usb cord. But to make sure go to your control panel and go to Devices and Printers. For those who have their setting on "category" in the top right hand corner, set it to large icons. OR small, your pick. By then Devices and Printers should be visible.
Then hook up your phone via usb cord, go to settings<Applications<Development and check USB debugging. Give it a minute and then check to see if you see something like LGE Android Phone. If you see it, but it has a ! with a yellow triangle around it that means the driver wasn't installed successfully. This could have been for multiple reasons and I can't provide the solutions for all of them so my suggestion to you is to google it. If you see that it installed successfully its time to root.
Step four. Turn off usb debugging but keep the phone plugged in. Then go into the Rooting for Optimus Zone (Hopefully you unzipped it, if not do so now) you downloaded and open up SuperOneClick.exe. It's icon is the droid guy with some red aura around him. Here you will be presented with a box, five buttons, and a switch with two options. Ignore the samsung captivate tab, because we're here to root an LG zone. On the "exploit" switch, click rageagainstthecage and then click the root button in the top left hand corner. Some command lines with stuff you don't understand may jump at you but don't worry. Nothing will blow up. When it gets to the "waiting for device" bit turn on usb debugging so it can begin the real rooting process. It may cycle a few times, but don't turn off usb debugging unless it seems the commands are repeating indefinitely.
Step five. Sit back, and watch your hard work, work for you.
Step six. It should say when its finished, and when it is it will prompt you if you would like the run a test. Run the test. If it fails, you DO NOT have root. You screwed up somewhere, or your phone is just plain screwed up to where it just can't be rooted. If it succeeds then unplug the phone, turn off usb debugging, power off and power on, and install/update "SuperUser" from the google play store if needed. Then wabam. Your LG Optimus Zone is rooted. Have fun recording your screen with screencasters, uninstalling default apps from the phone, and whatever crazy stuff you always wanted to but couldn't because you needed root. Well if you followed this step for step, you now have root.

Help rooting G3

Recently got a G3 with Verizon. Running Lollipop 5.0.1. I've done quite a bit of reading about rooting, and understand the concept. Decided to try rooting my phone. I followed the guide here:
http://forum.xda-developers.com/log...de-root-lg-firmwares-kitkat-lollipop-t3056951
I attempted to root my phone several times, on three different PC's each running Windows 7. The farthest I ever get is a 90% complete status where the GUI says "Rooting phone" and the phone says "downloading firmware." I've left it in this state for upwards of 10 minutes and I always end up having to pull the usb and remove the battery in my phone in order to restart it. Upon pulling the USB the GUI will immediately show it had completed the root but when I test for super user status (with Terminal Emulator "su" entry) it says "not found."
USB debugging is enabled. I have tried switching between MTP and PTP connections. I have tried several different USB ports on each machine I attempted this. I tried it by first manually installing the LG drivers on the computer as well as by letting Windows automatically install them. I have tried with the box that says to always allow connections from the computer checked as well as unchecked. I tried versions 1.3 and 1.2 of the script. With version 1.2 it seemed like it finished and it prompted me to push control+c followed by N and enter or something and then the command window closed, but the phone was not rooted.
What am I missing?
I'd really like to get this phone rooted as I am excited to create a recovery and experiment with custom ROM's.
Any ideas are appreciated. Thanks!

If the 1st method (one-click script) doesn't work for, the 2nd method using the classic way will. Download and extract the "New_LG_Root_v0.1_by_dig.zip" file from the OP, then open an elevated command prompt from within the directory you extracted the files to.

Thanks
I thought I fixed that link. Oh well. Glad to see there's a new method. I will try this. Thanks!

This worked by the way. Thanks again!

Help rooting a BLU Dash M

I need some assistance trying to find a method to root my Dash M (which appears to be extremely rare to find a rooting method for).
I already tried framaroot (tool I used to root my tablet before) and Kingroot and such, but none were able to do it (and all google searches led to videos on rooting a BLU Dash 5.0 or another device from the Dash range, which isn't what I needed).
The Dash M is running Android 5.1 and custom build BLU_D030U_V16_GENERIC 28-01-2016 15:41
If anyone could help it'd be very much appreciated c:

I have a Blu Advance 5.0, from the same exact family. In May, they had an OTA sent out to it to update the security. And little did I know, that meant no more root. Before the OTA to V06, I was on V04, and was able to root with Kingroot in less than a minute, perfectly. After the update, nothing good came of it.
For the past months I've tried hundreds of things to flash custom roms and recoveries (which I figured it out eventually) and then it crashed, due to a "damaged OTA". This meant that it couldn't update because I was rooted.
So here's the solution... If there's any older versions of your model or chipset (AKA Mediatek D030UX, D030U {MT6580}), download that firmware to your computer desktop as a (.zip) file. Then download the SP Flash Tool (Smart phone flash tool) from their website, and plug your phone into your computer via Media Transfer (MTK).
If you already have developer's options enabled, skip this.
- Go into your settings, go all the way down to "About Device", and find where it says "Build Number" (which will most likely have the phone brand in the file name). Tap on that about 8 times until it give a toast notification saying "Developer's Mode Enabled".
After you get that done, go back into your regular setting and now there should be a box above your "About Device" button that says "Developer Options". Tap that, then turn them on (press OK/YES if a prompt pops up) and then select the following options ,if available.
-OEM Unlock
-USB Debugging
Now plug your phone into a computer and install the drivers for your phone (it should do it automatically) and launch the SP Flash Tool that you had downloaded (extract to desktop before you launch, or it will show "error"). Now open the SP Flash tool and click on the "Scatter Loading" button. Navigate to your desktop, and find the firmware folder you downloaded. Click on that, then click on "Firmware", and it should bring up a .TXT file (Scatter file) with the desired firmware version you want. Click on it and press open.
A chart will appear in the space below with all the things the firmware has built in. All of them should be checked. Take out your battery now (from your phone) and plug the phone in without the battery. Wait for the model on the left to name your device, and click on the drop down list above the chart, it should give 3 options. Firmware Upgrade, Download only, and Format All + Download. Press Format All + Download. The bar at the bottom will turn a few colors, depending on what it's doing.
Now you're done! It's flashed. From that version, try to figure out a way of rooting it.
WARNING: Flashing erases all data on device, please backup to an external storage (SD CARD), before attempting this, in case you brick your device.

i know this is an old thread but.... i rooted mine (Dash M) with KingoRoot (look it up on Google)... i tried lots of stuff with no results, everything failed (i've already tried to root with KR in windows) but the only thing that worked was rooting with the android app in KR page... i felt really stupid after trying everything with no results when i've been using KR for other "hard phones".... either way, the only downside is that their SU manager displays all the time ads no matter where in the phone you are... but you can freeze the app to fix this and unfreeze it when you need to assign permissions....
BTW: its KingoRoot not kingroot (just in case)
