yes you can get a version back, any time with kdz, and that is the step by step guide. I used kdz on my L7 today and on my L5 you can go back to 4.0.3 any time. And you can install CM11 4.4.4 from 4.0.3 and 4.1.2 just flash recovery.
Root phone download L7cwm zip. Unzip in c drive on pc. On phone go to settings developer options, enable usb debbuging.
connect phone to pc with usb.
Go to your l7cwm file on pc c drive.
Double click bootloader bat.
On phone go allow. Phone will reboot when the phone turns on click on recovery bat phone will reboot. When your phone turns on recovery will be installed.

well you need to download kdz.zip first to your pc.
Extract the zip.
After that you need to find v10 frameware for your phone and download it.
On your pc open device manager, find modem and disable LG mobile modem. Restart your pc.
Take battery out of your phone hold volume up and connect your phone with usb to pc. On your phone you will see a yellow screen saying emergency mode.
open your kdz folder run windows enabler and start kdz update.
Set to 3QDSC and to Emergency.
Add your v10 frameware file and go start update.
Wait till its finished.
After that you will need to root your phone again and install cwm again.

4me it was a driver problem ...
drivers in download above should be good versions
if you are using win7 go to device-manager select everything like lg... or android... and uninstall with deleting drivers
uninstall lg suite, lg drivers, you can also clean up windows i.e. with glary utils, reboot, install drivers from above, connect phone AFTER installing all the driver-packages.
you can also try another usb-port
edit: maybe also a Security-Kit is blocking like Comodo Internet Security because it uses a sandbox for execution of unknown software.
Sadly I still get the same message in kdz with the driver prwnd (thanks for trying).
- I made sure that I uninstall everything related to lg and its driver
- Installed new driver, restarted.
- Connect the phone on download mode (volume down + plug in usb), the usb port is from the back of my comp, directly to mobo.
- Still no hope
I believe I read somewhere state that, if the phone can enter download mode, it's not fully bricked and I hope I can fix this phone for my friend...
Any help would be appreciated.
Re
Do you have access to fastboot or recovery??? POWER + HOME or POWER + CAMERA BUTTON ????

[HOW TO] Restore your tablet to stock + Reroot + Flash New Recovery

Before doing anything, make a backup to your external MicroSD card before continuing. Even if this method is very safe, and has been done several times without problems, we can't predict anything that may happen during the process.
RESTORE YOUR TABLET TO STOCK, APPLY ROOT, THEN FLASH A NEW RECOVERY.
This tutorial applies to both P3110 and P3113. They are the exact same models.​
REQUIRED:
Odin ( Take any version you wish. The latest ones should do the trick )
The stock Firmware file. Concerning this part, Google is your friend.
The official Samsung USB Cable that came with your tablet. It is recommended (but optional) to connect your tablet into your computer's built-in USB ports.
The latest Odin-flashable recovery. ( P3113 uses P3110 files )
CF-Auto-Root
Patience
Returning your device to a like-new state.:
1. Boot into Recovery Mode. This can be achieved by holding Volume Up + Power when your device is powered off.
2. Wipe all data. [ Factory Reset ( /data /cache ), System ( /system ) and Internal Data ( /media/storage )
3. Reboot into Download Mode. Usually found on the Advanced Options of most CWM-based recoveries.
It happens that your Tablet cannot boot into Download Mode due to various reasons. There is a battery trick that can be achieved. Do it when you absolutely cannot boot into Download Mode.
1. Remove your tablet's battery.
2. Connect your tablet to your computer
3. Your device should automatically boot into Download Mode.
4. Put back your Battery back into your device.
Click to expand...
Click to collapse
4. Connect your Tab to your Computer
5. Run Odin as Administrator + Windows XP SP3 Compatibility Mode ( Right-Click > Run as Administrator // Right-Click > Properities > Compatibility > Windows XP Service Pack 3 )
6. Click the "PDA" button, and select the previously-downloaded firmware file.
7. Press Start ( Do not check repartition. It will totally screw up your device. )
8. The installation process will overwrite all data on your device and install the stock firmware.
9. You are done.

Rerooting your device.
1. Reboot your device into Download Mode. From there, you are not obligated to connect your device to your computer.
2. Open Odin as Administrator + Windows XP SP3 Compatibility
3. Connect your Device to the computer.
4. Click on PDA and select the CF-Auto-Root package you previously downloaded
5. Click Start, with Auto Reboot Checked! Again, do not check "Repartition" as it may screw up your device.
6. Wait until it's done.

Hi, I have PA installed with TWRP installed. I downloaded my firmware from http://samsung-updates.com/. Do I need to flash the stock kernel as well? and stock recovery? Sorry for the noob question.
Maybe I'm just missing it, but I've gone to a couple of firmware sites and I can't find US firmware. Is there anywhere I can get that?
Does anyone have a link that's not to one of these stupid-ass, lame, @#$%ing pay download sites?
3 hours for firmware? WTF?

I have a similar situation. A previous rooting operation on my Tab2 7 P3113TS was either bad or partial and it appears it will not go into the download mode. power-pgup, power-pgdn, or just power all go to the Samsung splash screen then to a blue VeinDroid rom screen but no further. I tried 3 different version of ODIN and all recognize the device (port goes yellow) but cannot communicate. It stops at the SetupConnection step. Is this thing toast or is there something I'm missing?
WaryLouka said:
If a message is shown, press Volume Up. If you can't enter downloadmode normally, try doing "adb reboot download" in ADB. If you still can't, connect your phone to your computer, REMOVE THE BATTERY, hold Volume Up/Down + Power until DownloadMode is entered and put the battery in again. If your phone doesn't boot or/and battery trick doesn't work, use an USB Jig. If theres no usb jig, while until the battery icon is shown ( charging ) then do "adb reboot download" in ADB.

Are you serious????

I think it's not recommended to do anything like this only because of flashing a Fw, isn't it?^^

I have 4.0.4 ICS (cm9) on my LG L3 (e400), I tried to flash to stock since official 4.4 (kitkat) is coming soon but it does nothing, just reboots normally after flashing (no errors reported with kdz flasher) with my wallpaper and everything, and it says that my battery is charging but it's not connected to charger or computer. Any ideas?
I did everything from the guide, step by step, and I'm stuck on this error: Upgrade Error: Wparam: 100 LParam :1010
I especially looked ower firmware, and I'm positive that I downloaded the right one.
I tried several times, and every time I get this error. Also, phone now boots to Emergency mode, and can't boot to something else.
Don't know what to do? Anyone help?
Just reinstall driver, reboot pc after instalation and run kdz as admin.

You can only enter emergency mode because you haven't finished installing_KDZ. If I were you I would try download and install another KDZ file.
It will only work when you get the right KDZ file for your device. Don't worry to try another KDZ file.
Try another KDZ updater,
Unable antivirus and firewall.
Keep on trying. I hope these will unbricked your phone.

Have you tried entering into CWM?
If so, then you should do factory reset, wipe cache, and go to advance then wipe dalvik cache then restart your phone.

Tried that, tried flashing another roms, tried KDZ, tried multiple stock roms....nothing works.... It says it's charging without cable being connected.
stuck with cm9
For those you stuck and cannot flash back to stock ROM. enter to CWM, and leave it there. Connect to PC and flash with EMERGENCY mode (not DIAG)
Works perfectly, tested in Windows 8
Thanks!

Found The Solution
After hours spending to find the solution, finally i did it..
for those who having the same prob, here is the solution...
ONLY FOR ZTE BLADE Qlux 4G...........DO NOT TRY THIS ON 3G VERSION...U WILL NEED 3G VERSION FOR THAT....
sorry, i just found solution on russian firmware....but u can still change the language during setup..
download link for needed files:
https://cloud.mail.ru/public/gDXB/eVfZmaF2N
What is required for the process (included in the link above, just download that):
1.1USB VCOM driver. (18.8mb)
2.The original (not custom) firmware. (1.05gb)
3.SP Flash Tool (57.2mb)
4. Bricked ZTE Blade Q Lux 4G
Instructions:
1. Install the USB VCOM driver.
2. Start Flash Tool Administrator (Flash_tool.exe in the program folder).
3. In the window that opens, click the Scatter-loading (on the right side of the program).
4. In the folder with the firmware, select the file MT6752_Android_scatter.
5. Make sure that the Flash Tool automatically put down the boxes next to all the firmware files. (Picture attached for manual upolad &reference)
6. Click the Download button in the Flash Tool.

[GUIDE] [d855] How To Install Lineage OS - A Compilation (Downgrade/Root/TWRP/GApps)

*EVERY ACTION YOU PERFORM FOLLOWING THIS GUIDE IS AT YOUR OWN RISK*
That to be said, let's start: i am currently running the latest official nightly build on my d855 and it took me a while to get there. I couldn't find any (real) step-by-step-guide, where i would not have to google any errors or anything else.
Everything you find here is NOT my own knowledge, it is just compilation of sources, that i found on the internet.
Note:
Android 6.0: if you are on 6.0 and you always updated so you're on the latest security-patch-level the one-click-root-method won't work. I recommend downgrading your phone, which will be explained in the following.
Android 5.0: if you're on 5.0 you need to upgrade to 6.0 anyways, bc you need a different baseband-version to install LineageOS. This will also be explained in the following.
1. Make a backup of your phone
this is recommended, although i didn't do this, this is why i am not gonna explain it one here. I just saved my pics and contacts and did a factory reset, restarted my phone, did all the "first time turned on stuff" and connected to my wifi.
Note: Make sure your phone is charged to 60% at least
2. Download the following
a. Download LG G3 Drivers 4.0.4 and install them (i believe there are more recent ones, but this worked for me)
b. Download LG UP
- Download: LG UP Ver. 1.14: LGUP_Install_Ver_1_14_3.msi and LGUP_8974_DLL_Ver_0_5.MSI
- Make sure to install the DLL first and then the other .msi
SOURCE: Thanks to hyelton
c. Download the proper KDZ for you phone.
Note: I got this infos from a german site.
This is the 30C KDZ for the 32gb AND 16gb version: Download here
SOURCE: Thanks to mr bo
3. Downgrade/Upgrade your android-version
1. Turn off your phone.
2. Run LG UP (the tool you just installed) and press okay when you see the error message, that no phone is connected.
3. Press "Volume Up" on your phone and HOLD it, connect your phone to you computer via USB 2.0 PORT! This is important, bc connecting via 3.0 won't let LG UP recognize your phone.
4. Your phone is now in download-mode and LG UP should have recognized your phone.
5. Press SELECT, click on UPGRADE, then click on FILE PATH, choose you prefered .KDZ.
6. i recommend refurbishing your phone (This will wipe your entire system and make a clean install).
CLOSE LG UP and start it back up. The .KDZ should still be there. Now select REFURBISH and click on START. Wait until 100% completed and you phone has booted up completely.
Source and further information: Hail hyelton!
Also here is a youtube video: Thanks to kiaTech
4. Root your phone
1. Download the latest kingroot.apk from here.
2. Connect your phone (turned on, after all the "first time turned on stuff") and move the .apk to your Download-folder.
3. Open the (stock) filemanager on your phone and navigate to Downloads.
4. Install the kingroot.apk (enable third party .apk, when asked)
5. Open the app and root your phone (it's simple, believe me).
6. Your phone is now rooted (leave it turned on, DON'T restart)
5. Install TWRP and update to the latest version
1. Download this pack and unzip it.
2. Move the AutoRecMMD855.apk to your phone and install it just like kingroot.apk before.
3. Open the app and follow the instructions.
4. You now got TWRP on your phone.
SOURCE for #4 and #5 till here: Thanks to tute123456
5. Boot into recovery mode (either with the app itself i think or manually. If you have to do it manually. Turn of your phone. Press POWER and VOLUME DOWN at the same time until the screen shows soemthing. Release and immideatly press again. Your phne will ask you if you want to FACTORY RESET. Press YES and YES. If everything is working properly, TWRP should start up).
6. Connect your phone and download the latest TWRP.img you. In example here's the european one Latest LG G3 TWRP EUROPE
7. I assume you never disconnected your phone since moving kingroot.apk to it. So now you just move the TWRP.img to your Download folder.
8. Choose INSTALL on your phone and search for the TWRP.img. Select RECOVERY and flash it.
9. Choose REBOOT and then RECOVERY.
10. Your phone will boot into TWRP again. It should be updated to the latest version 3.0.2-0.
SOURCE: Thanks to everyone who contributed
6. Flash LineageOS and install GApps
1. Download the latest version of LineageOS (nightly) from here
Optional: make a backup of your phone using TWRP and safe it on your pc or internal SD Card, bc in the next step you will wipe your entire system, to get a clean installation.
2. Press WIPE in TWRP and select ADVANCED WIPE. Select everything but "Micro SD Card" and perform the wipe. This will wipe your entire system!
3. Move the .zip file to the Download folder on your phone and press INSTALL in TWRP. Search for the .zip and flash it.
Note: you'll see two red error messages. This is normal!
4. Wipe cache and dalvik as recommended.
5. Download your desired Open GApps package from here. Use "ARM" and "7.1", i recommend the "mini"-package.
6. Move the downloaded file to your Download folder on your phone and flash it just like you did the LineageOS file.
7. Wipe cache and dalvik.
8. In the main menu of TWRP choose REBOOT and then SYSTEM.
9. It will take a while to boot up, don't worry, just leave it there.
10. You succesfully installed the latest LineageOS build on your phone - you can now unplug your phone from your PC also :good:

Hi pheb92,
Big Thank You, If I had to do it bymyself it would have take me hours!!
-3. Downgrade/Upgrade your android-version -- I had trouble finding the right DLL on my Windows 10 system, onetime I managed to use LG - Up. At that moment the DLL loaded was 4.2.0.0. date 23-8-2016 device name "LGE AndroidNet USB Serial Port (COM6)"
- 6. Flash LineageOS and install GApps -- I flashed straight from a uSD card inserted in the LG G3.
Thank you for the great Setp-by-Step!

as far as i know LineageOS doesn't have an inbuilt root access (so far) like cyanogenmod did. you can only enable root access via adb in the developer options.
i did not root lineageOS myself so far, but you can try the following:
- Download superSU.zip from their official website and flash it via TWRP.
i would appreciate it, if you would share the outcome

LineageOS does have built in root management, but it doesn't ship rooted by default.
This change was made so SafetyNet doesn't get triggered by root and you can use Android Pay on your device.
Just download the su zip from LineageOS download page and flash.

I am stuck on this step. My d855 gets into download mode and LG UP recognizes the phone, but I'm getting the "You have to select a known model, please" error in LG UP. I have uninstalled and reinstalled LG UP and the DLL multiple times, same problem. I also tried uninstalling and reinstalling the driver, and I tried other drivers, same problem. I tried the tip in another thread (https://forum.xda-developers.com/showthread.php?t=2785089) to change the port to COM41 in device manager, but it didn't help. Btw I also unrooted my d855 (it has 4.4.2 currently) in case that's why the tool couldn't recognize it. Please help!!
Also @hyelton if you can help...
 @engmia since you were helping me earlier...
Thanks.

hi supperbowl,
are you sure you're using a USB 2.0 port and the original LG-USB-Cable, that came with the phone?
as far as i experienced it, 4.4.2 should not be an issue.

Have you tried it with the phone booted into the OS? With USB debugging on? Also if running 4.4.2 why not just use the old method?

No I've only tried it with download mode. I have USB debugging enabled in the OS. I am now trying the old method with LG flash tool, so far I'm getting stuck with the LG mobile support tool which keeps saying "upgrade stopped due to an error".
Edit: LG UP doesn't recognize the handset at all with it booted into the OS.

And USB debugging enabled?
If it's at least detecting unknown device while in download mode it most definitely should show up in lgup when boot up.
Choose MTP mode? And it's not just in "charging mode" or try vice versa?

Yes, USB debugging is enabled and my computer is allowed permissions.
Yes it's MTP and I also tried charge only and LG software modes. With LG Software mode it comes up with the unknown device in the model list again.

what also worked for me once was just retrying the process --> turn off, go into LG UP, go into download-mode. if LG UP does not recognize the phone: put the battery out of your phone, close LG UP and start the process again (also with different USB ports and other USB-Cables).
Hello,
Need to have unlocked bootloader ? Work on SEA version ?
You did not installed LG UP DLL properly
