hello i have lg flex 2 sprint it was on 5.0.1 ZV4 i just tried to root it by flash ZV6 root system through dd command
after flash the rootsystem image the phone reboot to lg logo with security error then it go down and black screen i still can enter download mode..
please any body can help me to restore stock rom maybe im on zv6 rooted system
I've never even heard of a ZV4 for the Flex 2, I thought we started with ZV5 originally when the phone was released in mid-2015, guess I just missed that one entirely if it does exist.
If you can enter download mode (you said you can) then I strongly suggest you flash the ZV8 TOT file found in the link provided in this instructional post:
http://forum.xda-developers.com/g-flex2/general/guide-lg-g-flex-2-stock-firmware-to-t3037593
Since we don't have a KDZ or TOT for ZV9 or even the latest ZVB firmware you have to flash those manually (not using the LG Flash Tool but the Send_Command.exe thing along with dd while the system img file is on the internal storage of the device.
I guess my one question would be: why haven't you updated when new firmware has become available, or did you just get this Flex 2 recently and it had ZV4 on it and you just never bothered.
If you do this right you can get everything working in under 30 minutes, and have even rooted ZVB ready to go (there's a rooted ZVB system img available now too, search the threads and you'll find the link to download it).
Be careful, read all the instructions, take your time, and good luck.
thank you very much for your help but I want tell you that I cant get the storage because the phone cant startup it just bootloop on security error so I cant put anything on the storage how I can transfer the file to storage
or can I flash it through lg flash tool?
I bought this phone from ebay and it come with zv4 I think who has it didn't do any updates

I have a D800, recently unbricked by shorting pins, and i have managed to install TWRP and download mode is working. I can't run any rom. I need to flash a KDZ through download mode.
But all the KDZ are of 10a/10b etc , does any body know where I can find a 30x KDZ or how to upgrade without flashing numerous FOTAs?
or will my phone boot up if i install http://forum.xda-developers.com/devdb/project/dl/?id=13450? i think not, but still need to know.

The AT&T D800 uses a TOT file to flash back to stock. Are you in the right section? If you have a D800 you can use this to go back to KK and it's just one FOTA thru AT&T to go to LP. http://forum.xda-developers.com/showthread.php?t=2663369
I got the phone from eBay and it has been rooted when it came out of the package. However, I failed to activate it to Sprint. The Sprint customer service representative told me to flash the original stock ROM. The current rooted software version is ZV6. I downloaded the ZV5.tot file and ZV6.img file from this forum, however I don't know how to flash them.
It seems tot file is from LG and the img file is from 3rd party, so I prefer to use tot file. However, someone in this forum said you would brick your device if you flash different version. Maybe to flash img file is safer.
Any helps will be appreciated.
Do not flash that phone with the TOT file. You will hard brick it!! Follow this guide to flash back the stock system.img, but make sure you flash the correct version! You MUST flash version ZV6. Once you flash the stock image, you can reflash with the rooted image. Although I can't see the rooted image keeping you from authenticating with Sprint... seems to work fine for me. But I would give reflashing ZV6 system.img a try. Should work fine. (I have done this process many times with no issues)
Hi I have a LG G Flex 2 LS996 sprint edition. It's running on firmware ZV9. I rooted it with the rooted system img. I kept the image inside my phone. Then I installed xposed and the flash mods. However, I wanted to revert to the stock rooted image, so I flashed the rooted image from download mode. The phone booted normally, and it got to optimizing apps. It finished, and it got to the lockscreen. It said systemui has stopped working. I press okay and then the entire screen went dark with only the wallpaper flashing every few seconds. At this point I'm not sure what to do. I'm afraid I might brick it because it has locked bootloader. Can someone please help?
Enter to download mode and flash latest stock rom from LG for your version. Not rooted image but stock image, and format your phone memory when flashing stock rom to be sure.
I have H955 and I use lg flash tool with stock kdz files from LG.

Okay so I did a factory reset and I had to setup everything again, however, my phone works. Now i want to find a way to completely reset everything to complete stock. The problem is that the latest TOT available for the LS996 Is the ZV8 but I'm currently running ZV9 so I'm scared that if I flashed ZV8 over ZV9 my phone will brick.
Hello guys 2 days ago i root my phone with easyroot and then i flash g4 mode with flashfire. I got brick (SECURITY ERROR ) authentication 9. Anyway i tried to flash stock rom with kdz file but nothing always stuck at 9%. Only one way left to save my phone i guess. I must install with tot file but i cant find for H955. Can i install H950 tot file on my h955 ?
Thanks for reading
Had to restore my phone earlier today and was able to grab the KDZ file for the latest nougat update for the LG-M470 model. Roaming around noticed some people had said the original file/firmware wasn't out yet but I guess they are now.
Download for anyone who wants it:

Thanks techboy11 for the kdz file. Do you or anyone know how to extract the stock recovery from this? I would like to apply the OTA security updates, but it only works with the stock recovery and I currently have the TWRP recovery.
Thanks,
Johnny
