When I try to use the TOT for ZVB to flash my device, device won't turn on (just sits at the main LG screen) so this is my only attempt at saving it, I got the TOT and DLL from the ZVB thread but I keep getting a "Download Failed" at the 9% mark. I did some research and it appears to be the DLL but can't seem to find a different DLL.
I have the same issue with a LG G4 LS991, can anyone solve this?
Guys dont upgrade. U lose the ability to roll back ealier firmware and lose the ability to root
The problem is that i was using my phone as every day. Then it restarted and never came back to normal. I dont know what version i used to have. But i cant find abother tot file for my spring ls991 phone. I already try the hard reset with no success.

OK, this post might be long. Feel free to skim. I just want to let people know everything that I've done.
So, my VS980 was rooted and I was trying to install a new ROM. I was going to try out Cloudy G2, but the installation routine only gave me international variants to choose from. I picked one anyway and my phone has been hosed since. I didn't have any download mode or recovery or anything.
I was able to get download mode back by extracting part of the firmware out with the LG Firmware Extractor and flashing that through fastboot. So, that part worked. I have download mode. I was going to try to restore my 24A firmware with a KDZ file and the old LG flash tool v 1.8.1 (the one where you put the ADB interface on COM41, and you use the updated megaunlock.dll, etc), but that no longer works for me. It keeps giving me the "failed previous load" error. I can't find a fix for that.
So, I've been trying to flash it (or firmware 26) with the LG Flash Tool 2014 (the one where you pick "Republic of Korea"). That will only get to between 25 and 49%, and then crash with an unknown error.
In between trying that option, I found instructions for extracting all of the bits out of the firmware and then flashing them to the phone partitions one by one. That seemed to work except I kept getting a security error on bootup. The only fix I found for that was to flash with the first flash tool I mentioned. Ugh.
The last time I rooted my phone and ran a custom ROM, my desktop USBs couldn't communicate with my phone very well, but my laptop could. This time not even the laptop's working. I even bought a new USB addon card (I needed it anyway, the USB3 ports on this suck). That seemed to get the computer to see the phone better, but it didn't solve my problems.
Can anyone help with this? I've scoured tons of directions already.
Thank you for any help

A little bit of progress
So, I finally got the older flash tool v 1.8.1 to start working. I've almost got it to flash the stock .TOT file (the KDZ file keeps giving me the "failed previous load" error). Now, I've kinda hit a new roadblock.
I think I mentioned that I got into this mess by trying to flash the CloudyG2 ROM, but that it's for international variants. When the flash tool tries to flash the firmware for the VS980, it thinks I have an F320S, and says wrong phone. Anyone know a way around this? I still only have access to download mode. No fastboot, no recovery, no ADB.
any luck? I bricked my G2 last night and I'm trying the flashtool to get back to stock 27A right now. Did you update your C++ library? I read somewhere that that can cause issues with flashtool..
Okay here goes....
I have a LG G2 VS980 which I was attempting to downgrade to Kitkat. I used a VS98024a_11.kdz (not exact name, but similar) to downgrade and the LG Flash tool, with the 3 blocks as logo. Now this is on a Windows XP laptop. The flash all went well, but now the phone does not start. When I boot it up, it goes to an erasing screen and stays there. Any help? I can't reflash it, because LG Flash Tool says the phone disconnected. Please help, ASAP, I hope to have it working by Monday, as I greatly need it.
Were you ever able to find out how to downgrade to Kitkat? I have a replacement device running LP 5.0.2 and I am trying to downgrade as well and cannot find any information on how to do so, or if it is even possible. I hope you were able to get your phone straight!
My lease is up got my Sprint G4 and of course I gave it ROOT a couple years ago. I have looked at several restore options but I am confused on which method I should use. I downloaded LGUP but the message I recieved was no handset found which obviously poses an issue. I am able to transfer files on my PC, but it won't set a PORT....when connected. I figured its the drivers so I downloaded the LG United thing but phone still is not recognized. I tried on my laptop and got the same thing.
Another issue is does anyone know where I can download the proper firmware to flash? From what I read, it looks like I can go back to LS991ZVB but I can't find it anywhere.
So my issues are:
PC won't recognise phone for LGUP
Can't find LS991ZVB firmware
I really need help. I just want to reset this phone and give it back to Sprint and be done with it. I haven't rooted a phone since this one so I'm a newbie all over again.
Try looking at the mellowmallow discussion thread. It explains how to get the phone to ZVB, I think.

If ure just giving it back. To them screw it just factory reset it. And maybe hide . wait a minute. Ure not on zvb or c rooted. Not possible just give it back to em. No worries either way.
I purchased the H811 off ebay last week because I am finally sick of my old Note 5 with no service at home. The G4 did great until I decided to flash it. The phone was on H81120i.
No big deal unlocking bootloader or installing TWRP. I flashed Lineage OS 14.1. About a minute after booting up, the phone got the error Camera stopped working. After checking more stuff on the device, nothing seems to work - i.e. - The accelerometer, speakers, microphone, flashlight, etc are dead. I installed a sensor test app and it doesn't detect any of the sensors.
After that, I downloaded LGUP and the stock KDZ file to flash back to phone hoping to fix it. Unfortunately, LGUP doesn't recognize the phone. It says unknown model but shows the com port, h81120i on the right hand side. I also tried LG FlashTool to see if that would work but it crashes about 26% into the it.
I have searched the forums up and down and have googled the crap out of this. I did find a thread from last month with a very similar issue a moment ago, https://forum.xda-developers.com/tmobile-g4/help/camera-stopped-audio-flashing-lg-g4-t3620516, and perhaps I should post in that thread, but my issue is that LG Bridge gives me an error stating it can't detect the software version.
If I were using Samsung, I don't think I would have this problem because I have unbricked several Samsung devices. The issue here is I am new to LG and have no idea if files are corrupt, if hardware was screwed, or what the situation is. I would hate to think that it was a $100 wasted.
Any help would be greatly appreciated.

maybe you got a frankenphone .. a supposely H811 and its not .. why not open it and see the actual motherboard and see wich variant you really have .seems like its not a h811 or try uppercut LGUP. see what it finds and downloads.

Uppercut found nothing... I opened the phone and found this though... EAX6658501_H810_MAIN_1.0
Of course, the tag on the inside of battery compartment says H811 with a date of 02/2016. Would it be a refurb or what? Anyway, I may be on the right track now.

maybe yes .. cover h811 and so software easy to edit.. but the only way is that take the motherboard and read the variant.
h810 is att?
I checked out the AT&T forum and found nothing other than stock that, obvious under my current situation, I can't flash because lgup with uppercut nor lg flash tools can flash.
LGUP gives an error code in the log file. PACKET_ERROR code = 1460
The phone internet still works. It has downloaded an update from t-mobile that's 460+MB that I can't install because I'm rooted with TWRP. Is it possible to update the phone with adb and TWRP? If I could find stock recovery, I would flash that and using autoprime's bootloader flash it back, even remove root if the update may revive the device.
After a week, a thought occurred to me and i tried it. I backed up a working h811 ( minus efs partition) with twrp with 20o firmware to an sd card then restored that version to this phone. I immediately wiped and flashed G4 20o with root zip file. It unbricked the phone and I'm currently using it.
Thanks raptorddd for replying and helping me. It seems that somewhere in the flash process something was corrupted and this fixed it.

youre welcomed but then phone is H811? or H810 i know that what ever the motherboard says thats your variant. am glad you have back up and running. :good:
It is crazy because the board said 810 but it had h81120i official when i got it. It worked but i have always used custom roms. Oh well, I'm going to stay stock with root. Just need to debloat now.
Hi Guys. I'm from Indonesia and I have LG G4 T Mobile H811.
I need your help to solve the problem.
It was all happened when I wanted to upgrade the firmware from Lollipop 10o to Marshmallow 20i.
First up I used LG Bridge, but it said that my phone has the latest software upgrade, so I was curious to see if I can upgrade it manually via LG UP.
I downloaded the KDZ File from cowstorage and selected the 20i firmware and flash it through the LG UP. The thing is, it says success on the PC but then my phone wont boot up. Goes into 9008 Qload mode and then I found a tutorial on Youtube how to fixed it and it can boot up again. One thing I noticed when flashing the 9008 thing is my phone changed from H811 to VS991 or something. It does boot but the phone is laggy and camera is not working. PC still detects as H81120i but the phone isn't working properly. IMEI gone and I don't know how to fix this. Does anyone have a solution to this?

flash a vs991 KDZ if it doesnt affect since you in a h811 KDZ that has antirollback..
you have franken phone means phone made up of other parts.. what matters it what it says in the motherboard.. if you want to be 100 % sure take out motherboard and see model number. software can be manipulated but not motherboard model numbre printed there.
