I started with the LG for sprint LS980 and tried to flash it for US GSM radios.
Got bricked in a T mobile loop using the LG Flash tools.
When attempting to flash the stock Sprint the flash tool would only recognize the phone as the T-mobile variant.
This caused me to get the 4.2.2 up and running but it will start and if the screen timed out then it would reboot (and problem was also the fact that my keyboard didnt work.)I got Kit Kat to work via flash tools no problem (except for radio). and as everybody knows that TMO version of KIt Kat doesnt work with IOroot. I downgraded and now I'm back to the phone starting up and and rebooting at random. I was able to run ioroot but cant tell because the phone wont stay on long enough for me install root checker, su, or autorec. I would like to get the Sprint back but If I can atleast get a custom rom I can work it from there
I used T-Mobile USA D80110C_00.kdz to flash with the top method hyelton supplied but (remind you my phone is a Sprint phone but it couldn't feel any farther)
adb is not gon cut it cuz the phone will not stay on
Where did I screw this downgrade process to 4.2.2. and can I get back to Sprint? I jus got my straight talk sims Im ready to roll.
Alternative Strategy
It says Service Disabled. Is there a way to fix this?
pretty sure I need root.
I cant see the options for mobile data either
BTW S/O to everybody here yall be going in
Hey guys, I bought my phone used and am trying really hard to fix a broken root that's on the device.
It's a Sprint LS980 with the latest ZVE update. Rootchecker fails, and the SuperSU app is unable to update the binary. StumpRoot will not run as it thinks the device is already rooted.
The phone is on stock recovery. My plan was to flash the stock ZVE firmware/ROM using a .tot, however this is impossible until I can get download mode working...
Any help would be very much appreciated, I really want to get this phone sorted out.
Bumping up, I'll be working on this more tonight since I'm working graveyard shift at an IT helpdesk. If anyone has any ideas please let me know.
I rooted my phone a while back with Cloudy G3 and it worked pretty good for a few months, then the 4G stopped working. I had my sim card replaced, but that didn't fix it. I then tried fixing it and hard bricked my phone. With the help from this site, I was able to get it to download mode. I did the update software from lgmobile and it installed 4.4.2 and did a factory reset and the 4G still didn't work. It now has 4.4.2 and I had to root it with stumproot, because towellroot wouldn't work. I then used the flashtool using the kdz file, but it still didn't give me my 4G back. This time I was able to root with towelroot and install all my rooted apps. I found the apn settings for verizon, but after I put them in it won't let me click it as an option. When I go to the setting there is one called vswinternet, but I can't update it. I seen on the net about deleting lteconfig.apk, but I don't have it. Any ideas?

Then download the lteconfig.apk this will give you lte
I did , but it didn't do anything. I even copied the.apk
to the location and restarted, but nothing happened. It's version 1.40624
Any other ideas? I even went through the build.prop settings and tried adding a new APN with the Verizon settings I found, bug it doesn't one. Is it possible I did something to the hardware? I tried different roms. Will flashing the modem.img do anything?
I've got an unlocked LS980 G2 that's been flashed to the Boost Network. Currently running KitKat 4.4.2 , but when I proceed with install the phone resets, appears to install the update slowly till about half-way then skips straight to the end. After restarting itself, it's still running 4.4.2 and says no updates are available.
The phone was previously rooted, but I performed a full unroot via SuperSU, factory reset and confirmed via Root Checker. Any idea what I'm doing wrong here? Help me please XDA!
Are you sure the update was for zvg? Could have been an update for zvc, happened to me. I had to tot to zvg(lollipop).
Sent from my LG-LS980 using XDA Free mobile app
i have the same problem on sprint network please help
Hi, I followed the DirtySanta tutorial, used the US996 DeODEXed Rom. I knew this was a possibility but thought that I could get back to stock using the KDZ, unfortunately my phone is now seen as US996. I've tried modifying both the build.prop, and KDZ but I still can't get LGUP to flash back to stock. Is there anything I can do?
Service Unavailable is probably due the frequency signal issue.
Remember that Wind runs in AWS bands, while the US996 runs on regular bands (Bell, Rogers, Telus)
I'm sure the phone works fine if you use a Rogers SIM on it.
so, the trouble / solution is figuring out how to flash back the Tmobile / Wind modem back into the phone.
also set the phone to use the proper AWS bands 1700 / 2100, or the new LTE band 66

T-Mobile H918 supports LTE Band 66, try and flash a H918 ROM maybe? Or access the hidden menu and enable AWS, but you'll lose LTE and only have 4G that way.
See here to access the hidden menu but change 915 in the command to 996 or the model the phone is showing as.
https://forum.xda-developers.com/v20/how-to/access-hidden-menu-h915-t3515098
Edit: Let me know if it works, and you get LTE back (not just 4G) I really want to know to root my H915 as well. You used the [LS997|VS995|H910|F800L] DirtySanta Bootloader unlock and Root guide by me2151, right?
Second edit: If you're going to try to flash an H918 ROM I'd strongly suggest you flash an H918 kernel that is suggested in the dirty santa thread, I think the Konverged is what people are using. No hard evidence either way flashing an H918 ROM would work but it may not as the boot image is a 996.
Thanks guys. I flashed the Konverged kernel earlier, it helped crash-wise but nothing on the signal end. Last night I extracted the files from the H91510e kdz and tried to flash the modem that was included but that hasn't helped, I want to try the CDMATool but it isn't recognising my account so I'll wait for a bit. I tried to use the hidden menu but it doesn't seem to do work on this firmware unfortunately.

Try this, make sure USB Debugging is enabled. Turn off phone. Remove the battery. Put battery back in. Hold the volume up button and plug in USB cable. It may boot into download mode or it may boot into the dirty santa corrupt screen. If it does boot into the corrupt screen , let go of up button, press the power button then IMMEDIATELY press the volume up button. Either way you should be in download mode. You want download mode, not fastboot. Make sure LGMobileDriver_WHQL_Ver_4.1.1.exe drivers are installed.
Download LG Support Tool. http://www.mylgphones.com/lg-software-tools-download the 'Download and install LGMobileSupportTool.exe' link. Install and run it. If you've already installed the drivers hit cancel when they go to install.
Then go to 'Options' 'Upgrade Recovery' Make sure you have the IMEI number from under the battery and put it in no dashes or spaces. It should download and install the firmware if you've done the tap 'About Phone' 'Developer Options' 'Enable USB Debugging' but I'm sure you know this.
If all goes well you should be back on stock firmware.
Hope it works, it should but I'm not 100% sure.
The good news is that it recognized my phone as H915, but unfortunately half way through the setup it through a weird error. Part of me is thinking of restoring my twrp backup and trying uppercut again. I'm hoping that will get the program to see my phone correctly.
EDIT: I tried the KDZ installer again, without trying to restore the TWRP backup and my phone is back to stock and getting a signal. Thanks again to the both of you.

What I suggested worked without the TWRP backup? Or another way?
your best bet is to somehow find a way to install the stock rom through TWRP then you can install the KDZ. Cause I had the same issue as you, i have a Verizon V20 with the US996 rom and it wouldnt let me flash the verizon KDZ until I installed NotSoStock rom thats based on the Stock Verizon Rom
EDIT: Just saw you got back to Stock. Disregard this lol

I didn't use the TWRP backup at all in the end. Your method didn't fully install, but it made the phone see itself as an H915 again which allowed uppercut/LGUP to install the KDZ so it was a big help
Congrats! on the recovery, this is a good reference thread for anyone trying to recover from a bad root, and needs to get back to stock.

Are you saying you have a rooted 915 with everything working?
guess not lol
I am having the same issue with an h910, but the service only works sometimes. Many times it is searching (and draining the battery in the process), but sometimes it will get service and be OK. Quite frustrating, and no way to revert because no kdz available. Anyone else with h910 having this problem?
Hi,
I'm not sure if I'm off topic here or not. I have an LG V20 H910-10c (Nougat 7.0) and I am having an issue with a Service not working after using DirtySanta to Root my phone and I am praying that someone can help me out with. I have already tried a Factory Wipe/Reset and Wipe Dalvik/ART & Cache and have Formatted Data to remove Encryption, etc..
Timeline: The phone worked fine in all aspects before Rooting it.
After Rooting it, I had this issue.
I then tried a Factory Reset and got stuck in a TWRP Bootloop.
I fixed the Bootloop issue with a Reset (Yes then Yes).
The issue is still there.
ISSUE: When I boot into Android, I get the following message;
"LGSmartcardService has stopped"
.....and I cannot use my External SD Card (TWRP sees it fine, I Flashed SuperSU from it).
I have Googled my brains out and simply cannot find any suggestions, except to perform a Factory Reset, which I did and that's what put me into the Bootloop and I reset the way you said and now it boots up okay, except that error message is still there.
I have not put any apps on the phone or anything. It's factory fresh (except for Rooting it).
I hope I'm not violating any rules by posting this, but the page I used to Root it has a REAL SMALL downloadable file called "V20-Root.zip" that contains everything, including the Batch files with the steps that they perform in them. I did NOT use the ROM, as that's ONLY for Sprint users and my phone is an AT&T model (Unlocked and my Carrier is MetroPCS). But I put it here, just in case someone wishes to bless me by taking a look and seeing if there's something to note. I am not a coder by any means. I do understand some basics, but I couldn't see anything that would cause this sort of problem. I did NOT install the ROM listed, because it's for Sprint users ONLY and I have an AT&T (Unlocked, using MetroPCS) H910. Here's the link to the page:

I really need my Ext SD Card to be seen! I use it extensively and it would be a real hindrance not to have it! Plus this is my ONLY phone (no landline) and I am disabled and must run everything, including my home network and laptop, etc. from it and I need its space for things I have to have available on my phone to do things that I need to do, so any help would be appreciated GREATLY!
I do need to be Rooted, so going back to factory with whatever Mpdel # ROM an LG Tool sees me as might make me unable to Root again.
Please Help Me and Thank You!
