are zip available of completely stock room? I want to unlock my phone and the sim unlocking screen doesn't appear on the couple of xda rom I've tried.
It'd be much better to just flash stock instead of going through the OP method, then root it and install Cwm again. thank you!

Thanks! Only thing about the LG IMEI checker is that it only works for kdz / non USA models. And it only gives the latest for the area of the kdz for the phone. Reason why I host my own kdz files is due to people can downgrade & upgrade firmwares as they choose. (LG deletes old files & sometimes there server doesn't even work) which is sad lol.

I have requested from my telephone company the unlock code and I will have it in a matter of days. Using modified rom for some reason the prompt to insert the unlocking code doesn't appear.
oh well, time to flash stock once again :)

Possible Device Connection Fix for Verizon G2

So I had a very hard time with the drivers and what not. I installed all the drivers as directed from the instructions but when it came to the window where it was about to actually "Update" my phone, it kept saying that the phone was not connected and a yellow triangle was next to LGE Device in the device manager. I made sure to restart and I tried to manually choose the driver as one person on here suggested, and I also tried re installing several times but none of that worked. I then strayed away from the instructions a bit and it worked. Doesn't mean for sure that this will work for you or if it just worked by chance, but I figured you guys might want to know what I did...

- connected the phone in download mode
- Uninstalled LGE Device from device manager
- Installed LG Driver provided in instructions
- Instead of downloading the verizon driver provided by OP, I just went to the Verizon G2 support page on the LG website and downloaded the driver that they provide.

after that, I tried "updating" it and I had no problems.

Sprint LS980 identity crisis, D801 on all fronts

Yes i did, and they it shows the android dude, doing his thing and then the phone restarts and from there boots up, but im back a square one, were the phone load and then crashes once u unlock the screen and reboots.

What firmware did you flash? also was it the firmware meant for your device?

Sent from my SM-N9005 using Tapatalk

I would like to pick this discussion up because this where I am.

I started on the Sprint LS980 Kitkat and bricked it trying to flash the wrong rom. I unbricked it by but the LG flash tool recognized my phone as D801 and I flashed the Tmobile USA Kitkat thinking all I need to do was downgrade and root the 4.2.2. Even after hard reset I still get bootloop.

It will stay on if I keep touching it and I was able to run ioroot like that but Google play and keyboard don't work handcuffing the ability to jump on wifi. installing autorec or superuser apks left me with the installing screen and I can't type fast enough for adb commands

Also I have the word Error on the bottom of almost all screens. I think thats something with the keyboard

Weirdly enough the phone is functional on T-mobile Kit kat buildprop d801e except for
Wifi acts weird
Neither GSM or CDMA work
Mobile data can not be turned on
front shows sim card and Service disabled

    [CENTER]Common Questions and Problems KDZ Method:

    1.Network connection error is NORMAL, move the window over and you'll see its actually most likely flashing

    2.If your getting errors when doing the kdz method and running a custom rom that could be the problem and you'll need to use the TOT method.

    3. Getting connection errors? Check under device manager to make sure you see LG something related under communication ports (Windows 8/10 ports might be hidden)

    Make sure your using a USB 2.0 port!! USB 3.0 will NOT work.

    Common Questions and Problems TOT Method:

    If having an issue try and choose Board_ID on the TOT/DLL selection screen.

    Make sure you've set your COM port to COM41

    If device does not start flashing besure you unplug and replug the device

    Make sure your using a USB 2.0 port!! USB 3.0 will NOT work.[/CENTER]

    NOTICE! - IF you download fails or does not download all the way USE A DOWNLOAD MANAGER!, Files that are usually over 1GB browsers have issues downloading them espseically if you have a slow connection.


    First Off Not Responsible if you flash the wrong one!!!!
    Please Check to make sure you don`t flash a 16GB firmware on an 32GB device. Please check the file names if they have an "16GB" in the File Name

    THIS Guide Below for All Versions EXCEPT the AT&T Version (For AT&T & Sprint Scroll Down more)

    Normal Flash: Flash ROM without losing any data. Only use this when you need to fix system error. Beware of boot loop when flashing ROM that differ from current ROM on your phone or MOD ROM.
    CSE Flash: Choose this option when you need a fresh format. All data will be gone. It's suitable for upgrading or downgrading ROM or simply use this when you need to back to Stock.

    This error means you where running a rom not meant for or built on a different model#.

    Install:
    2.Install LG Drviers
    3.Install Flashtool (Don’t run it yet)
    4.Extract the TOT file from the Zip

    14.You may need to unplug/replug phone before Firmware install will start (If it does nothing after clicking the yellow button


    15. Should take anywhere between 4-8 Minutes, When its done your phone should reboot

    Do NOT Close the FlashTool Window during firmware update.

    99% of the time FlashTool will FAIL after 85% anything after 85% is just your phone rebooting so your safe :)


    _____________________________________________________________________________________________________________________________
    Remember if you have bootloop or stuck on LG Logo after flashing make sure you FACTORY RESET!

    LGUP Method:​
    Flashes both KDZ & TOT files:
    Thanks to @shakeyabooti for LGUP!

    Download LGUP from HERE
    Install the file with the DLL name in them first and then LGUP_Install_Ver_1_14_3 Then copy the folder "common" to C:\Program Files (x86)\LG Electronics\LGUP\model (this should resolve unknown error)
    Make sure you have downloaded the required KDZ file MM or LP
    Open LGUP on your computer "make sure your phone is plugged in"
    ARE YOU HAVING TROUBLE WITH LGUP NOT SEEING YOUR MOBILE?
    Try this....... take the back off your mobile so you can get at the battery. Connect your mobile via USB. Start LGUP, if it does not see your phone DO NOT DISCONNECT, DO NOT RESTART OR TURN OFF LGUP. Take out the battery and then put it back in.......let the phone restart on its own. LGUP should now see it.

    LG Drivers: in First post

    TO DO A FULL WIPE AND INSTALL MM - Open the LGUP on your computer. FILE PATH point it towards the MM KDZ.
    IMPORTANT!!!!!!! shut down LGUP!
    Now open LGUP again - you will notice that the MM KDZ will still be showing in the FILE PATH section. Select REFURBISH and make sure BIN file is ticked. Press Start. Make cup of tea and be patient

    TO GO BACK TO LP FROM MM - Open LGUP on your computer, click on FILE PATH and point it towards your LP KDZ. Close LGUP and re-open LGUP. Make sure you select REFURBISH this will do a FULL wipe, tick BIN file. Press Start. Make cup of tea and be patient
