flashed tmobile firmware on and ls980 g2.. can i fix it? please help

I flashed a stock 4.4.2 t-mobile firmware to my sprint ls980.. is there anyway to get any ls980 firmware back on it? i use it for tmobile which is why i flashed it but seen a few threads on how to unlock the sim and now im stuck. did i ruin the phone? or could i at least get it to work through tmobile with the firmware i flashed? i cant even get it to connect to google play. wifi works tho

Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck

First: Grab the ZVE Tot file
Second: Flash it in download mode.
Good luck, flashing in download mode is rather a pain to do.

There is a DLL file that is generic that should overcome that problem.

Facing the same problem..please help
I've also done the same thing just a little bit different.
i flashed D802 (international version) kdz file over my sprint g2 (Model is LS-980) but it does not work, when i turn on the phone I can't even complete the setup and the phone restarts. touch panel is also not working right.
Now i've downloaded the stock .tot rom for sprint version and trying to flash it using lg flash tool in download mode. But it does not flash it. It detects my phone as D802 and gives the error about the model number does not match
I need help getting it back to LS-980

Supposedly there's a stock .kdz which I can use to extract the .dll from, but I haven't found any stock .kdz file so far.
So, this generic .dll sounds great and one of my last options left. I'll appreciate if you can point me to that file. I'm going to try to find it.
Thanks a lot!!! :good:

I've tried this .dll file with both the stock ls980zvc and ls980zve .tot firmwares.
but the flash tool gives this error "CrossDL [D802] to [LS980]. SWversion"
Is there any way around this?

Once the kdz or tot is available you can bet it'll be here as "Hyelton" is a wee bit OCD about having "back to stock" guides up for just about every phone that you can imagine. He's already got the thread up and ready just not the kdz/tot file needed

Right, I'm new to LG phones (not new to android though).
What's a kdz? Is it like a full software package for LG phones?
Sent from my LG-H815 using Tapatalk

It's a full original LG ROM image. You can use it with LG Flash Tools to flash your phone. You can read more information about it here (but for now don't use it on the G4 until we know for sure that everything works at it should) -

Downgrade from MM to LL with LGUP is possible!

Just wanted everybody to know that you CAN downgrade your MM LG G4 for Verizon by using LGUP.
And this is how...
1). Download all The Files Below!
1) Firmware Files - Click HERE!
Or Here LGKDZ.com for your exact match KDZ for your model
2) Download LG Drivers - LG Drivers Here - 10.9 Mb
2.1)Verizon Drivers (Verizon Only)LG_VZW - 7.8 Mb
3..LGUP can be found on this website LG UP DOWNOAD
You have to sign into one of your accounts and like the page for them to open the downloads in the middle of the page.
4. install the drivers then the .msi file for LGUP. Usually there is a DLL file and the LGUP application, install the .DLL file then install LGUP.
5. First make sure that your phone is showing up on LGUP, if not make sure you have USB debugging enabled and the you are connected with MTP.
6. Find your .kdz file, and don't press start VERY IMPORTANT!!, Exit out of the application and then REOPEN LGUP and your 13b.KDZ should still be in the box at the bottom.
7. Now just press start and wait for it to do it's magic.
And now your back on LL and you can get back to rooting this phone.
And just so people know it is not possible to downgrade from LL to KK, it will brick your phone for some reason, and trust me I had to send mine back and get a knew one, nothing would get it to work again!
So that's how you get back to LL from MM, which seems to be the only way to have root at the moment...
One more thing, I was able to transfer the files for the effortless root on MM but you can't do any send_command.exe commands because it just says FAIL. but it did switch the system software from Official to Modified so it did something just not what I wanted it to do....

If there's anyone wondering why this works, it's because both the 13b and 24c kdz's both have the same qfuse number, so the bootloader accepts both without bricking. If Verizon ever puts out an update that increments the qfuse value and you take it, you won't be able to downgrade to 13b or 24c.

I have the kdz file but it wont let me put it on lgup. It's looking for a .tot file. Help would be greatly appreciated
Nevermind. Figured it out

would this work with h811

Thank you for the info! Just curious: how do you check the value of qfuse?

I did this on a Canadian variant H812 and it worked. Rooted right after and that worked too. I am a happy camper.
I loaded H81210n.
Anyone reading do note that I did not use the Verizon files above.

What you must do is tick the update and select the kdz file. Then close LGUP, open it again and select refurbish and kdz file should be there. Start the load.
This phone with L and root is perfect. No M for me until root (if it happens). Really enjoy having the changed DPI with root and no permanent notification for Priority mode.

You can DL from here, without "liking" anything. http://www.droidopinions.com/download-lgup-tool/

I haven't done it just yet. And I know I'm not the smartest here. But to my knowledge yes you will lose everything. So always good to back up all your files. I've got all my photos backed up to google photos. over 5000 lol. But yeah from what I understand it's the same as doing a factory reset except instead of factory resetting back to MM you're factory resetting to LP.

(Request to a moderator below my response to stephen293)
OK, I did mine last night and using the refurbish mode as said does in fact delete all data.
((TO MODERATOR CAN WE GET THE ORIGINAL POST UPDATED TO INCLUDE THAT TO LOCATE THE KDZ FILE YOU NEED TO FIRST TICK THE UPGRADE CIRCLE)) I found it down the thread, But just figured it would be easier for others if it was included in the original post. Thanks

Big ups to everyone who made this happen!

Hey sorry but the www.lgkdz.com doesn't work. Is there another site we can find all lg firmware to downgrade for our exact lg variant match....

From OP second 1), try : http://storagecow.eu/index.php?dir=Xda/LG+G4/
or check the XDA G4 section for your variant.

Thank you for your response. I did actually download the H812 kdz from storagecow however when I put it in the LGUP tool it read as an error in the tot file. I'm not sure what happened or where I went wrong. I'm so confused at this point and without my G4 being unuseable at this time. I also wanted to ask if the kdz you directed me to are in fact the file I need to go back to LP from MM?

Does reverting to 5.0 from 6.0 brick your phone? Rooting/Downgrading Help!

I have tried every method I can find to root my g3 6.0. Kingroot, PurpleDrake, etc. I've tried every method to revert back to 5.0 I can find, LGUP, LG Flashtool 2014 and 2015, none of them work.
I then decided to give up and pay a shop to do it for me. But when I asked about it, they said they couldn't do it. Reason being that 6.0 updated the boot loader, and if you tried to revert, it would brick the phone. If this true or did they just not know what they were doing?
If anyone can help me to root this phone or revert to 5.0 I'd really appreciate it! Nothing I find seems to work.

If you have D855 reverting with LGUP works.

Is there any truth to downgrading bricking my phone?

I can't really tell. I think no. BTW did you even tried to downgrade with LGUP or you write nonsense in OP?

No I did try the guide on https://forum.xda-developers.com/showthread.php?t=2785089
When trying KDZ method, it just stops after loading the LG update tool, tells me it encountered an error, or it couldnt connect to the server. I tried leaving it for 15 mins, then unplugging and replugging it back in, nothing happend.
When trying TOT method, I get a version mismatch. I know I have the right version of files but nothing.

Looks like there has been no luck rooting Canadian G3 so far: https://forum.xda-developers.com/lg-g3/help/root-d852-canada-marshmallow-6-0-t3356842

I had the same problem with the KDZ method. Did it ask you if you wanted to retry? When I chose to retry, it worked fine afterwards. *
*Caveat...someone told me that that unable to connect error is a false error and that it should just continue after clicking retry. I wound up having to unplug my phone, pull the battery, rebooted/reconnected into download mode, chose the retry button and it worked.

i have successfully downgraded from MM to LL following this post.

Not much info about the update,

The current software update gives you the most up to date Android™ security patch on your device."
form Verizon site.

Lame... Where's 7.0 or even better... 7.1?!

Mine got the update but after two days back on 5.1. Battery Life was awful

Anyone got a KDZ yet? Got a phone that locked on boot a day after the update. Standard fixes didn't work and can't use previous KDZ as it stops at 5% or 6%

Would also like to know if anyone has successfully downgraded from 2AA and if they can provide a KDZ.

Did you use LGUP to get back to 13B from the new 2AA using the 13B KDZ file for Vs986?

Confirmed working. Downgraded from the dreaded 2AA to 13B using LGUP.

Help please unlocking GSM radios on LG G4 with VS9862AA
Hello, a family member received their phone back from LG with a replaced motherboard due to the boot loop issue. We got it back with the VS9862AA software version (Build Number MRA58K).
Can anyone one point me to instructions on what to do to get the GSM radios unlocked so they can use the phone on AT&T or T-Mobile? I remember doing the install to 6.0 Marshmallow maybe a year or more ago when it wasn't available yet officially, and that one had the unlocked bootloader and GSM radios unlocked. So I'm somewhat familiar with the process, I just need to go back and revisit my notes I made about the ordeal.
Has there been any improvements to make this process easier if we just want the GSM radios unlocked? Any help would be very, very appreciated. Thanks in advance!!

Edit: Ok, so I searched my pc for LGUP_8994 and found a dll file of the same name in C:\Program Files (x86)\LG Electronics\LGUP\model\8994 so I replaced that file with the one found in this thread. Now all is well, and I have successfully downgraded from 2ba!

Can someone give me a link for the dll file for the 2ba update. I tried with the YouTube video but it's no longer available and can't find it anywhere. Please and thank you
