D852g Cant revert to stock - G3 Q&A, Help & Troubleshooting

Good morning
Im using a Canadian version of the LG G3 D852g on Videotron network.
I have been able to root and twrp the phone no problem. I have tried most of the roms available (candy cm 12 etc)
I installed cloudy 2.5 for my model of phone and since then i have been unable to revert to the stock OS via the KDZ method or TOT.
What is odd is that the KDZ worked no problem until after i installed cloudy 2.5
The KDZ method would now stall at 2% and indicate that it can not find my device. (yes i know drivers com port 41 etc etc etc)
I downloaded tot file and dll required for my device and when i run the LG flash tool.
SO then i tried the TOT method to revert to kit kat. and this is where i got a weird error message

Any help would be greatly appreciated

[Q] LG e980 AT&T - Download Mode Changed - BIN model is different

I bought this LG E980 AT&T model (v20G) and I installed E988 stock 4.4.2 OTA ROM (.kdz method) given by sandyiscool in this thread
http://forum.xda-developers.com/showthread.php?t=2754294
it was successfully installed until i realized there's alot of modem problems i.e. my 3G would show up but would run very slow as compared to other phones using same carrier.
So now I wanted to revert back to Stock ROM E980 (.tot method), but as soon as i put my phone in download mode and plugged into the PC, LGFLashTool gave me the error "Bin model is different" and then got red and failed to install Stock ROM. I think the download mode model has been changed to E988 while i was installing its OTA Rom.
Is there any way to revert this download mode back to E980 model. I tried both E988 and E980 .dll files for .tot flashing tool but both gave same error. I can only find E980 TOT files and cant find E980 AT&T v20g .kdz file anywhere (I think that may solve my problem if i find it). Please provide a solution to let me revert back to E980 OTA rom. I'd be really thankful.

Need help with returning G3 D855 to stock.

So I have a D855 16GB LG G3 running CloudyG3 2.5 and I've been trying to revert it back to stock android in order to update to Marshmallow through LGs PC Suite. I've tried following various guides to either flash a kdz or tot to android 6.0 directly. I've also tried to downgrade to a previous version of LGs stock android but they've all failed. When I tried to use LGUP from this link it discovered my phone and displayed what software it was running and such but the model section stated "unknown" which made it impossible to proceed.
I then tried the second option in that thread, flashing the kdz with the lg flash tool. That journey ended when the program stated that no device was plugged in, even though the phone was definitely plugged in and in download/firmware update mode.
The third option in the guide was to use a flashtool and flash a .TOT, but when I entered the device manager to change the com port of the LGEModem but that one didn't show up in device manager so that also failed.
I'm starting to see a connection here in that the problem lies in the connection between the phones and the pc somehow. I'm using the original usb cable if that matters. I have TWRP 2.8.6.0 installed if anyone knows how to install the stock marshmallow update using that. I found one guide but it said that it required TWRP 2.8.7+ and I'd rather not try to change it since I've had a ton of problems with different recoveries, namely being that the touchscreen doesn't work in most of them.

Reinstall firmware

I have the 22a kdz, but the software I've downloaded to flash it onto the vk815 isn't working. Would someone please point me to valid files for downloading? I tried the apps to SD hack, and that makes my software modified. That didn't seem to work, and maybe why the 23a update still gives me unexpected SD ejection. I want a clean pure install. I'm not concerned about root.
Hi.
First, are you using the original USB cable with a USB 2.0 port that comes directly off your Windows PC's motherboard - not a USB 3.x port and not through a USB hub?
Installed the latest VK815 drivers from LG's website? Reboot the PC after while the device is disconnected from it.
Once you put the device in Download mode, check in Windows' Device Manager in the Port section to see if the device is listed "LGE...". Until it is, any attempts to flash a KDZ or TOT will be futile. It can take up to 5-10 minutes to load the driver you installed, and USB works by loading the driver separately for each different USB port you plug the same device into.
If you Google:
Code:
XDA LG Flash Tool 2014
you'll find it. If that's exactly what you're using and it's not working, could you please be more specific about how it's not working? 99% of the time (maybe only 95%) ignore any error dialog that pops up from it, move the error dialogs out of your way if necessary but don't click on any buttons in them, and within 5-10 minutes you'll find your device is flashed. This is true in general for all LG devices.
You should also be able to use the official Verizon-LG software on your tablet, if absolutely needed. When you first plug it into your Windows PC it comes up as "Installer" before it switches to MTP or another mode. Install that from Windows and the official tool will download and install the latest KDZ that's released (23A? - I have the VK810 so not sure what latest VK815 releases are). The difference between the official tool and LG Flash Tool 2014 is the official tool downloads the newest KDZ every time you choose to upgrade/update with it, and can't make use a pre-downloaded KDZ, and then deletes the KDZ when it's done flashing although if you're fast enough you can copy it elsewhere while it's flashing so you have it handy. It's the easiest way to get the latest KDZ for any LG device on Verizon these days, when it's not available any other way yet.
When you flash with LG Flash Tool 2014, use the CSE option which will wipe everything including user apps, user data and internal storage.
Lastly, if you return to stock and the problem persists and it's still under warranty, LG has excellent warranty service.
Thanks! It all seems like I was doing everything right. I'll give it another go as you've directed, to be sure. It was my understanding that perhaps when it updated to Marshmallow, the flash function was deactivated? Maybe that was just for installing images and not flashing firmware.
Yep, fails to connect. Trying to install the LG UP CY dll for vk815, getting an Error 2356. Bummer.
Crap, just lost everything I just typed.
You verified the tablet shows up in Device Manager while it's in Download mode?
You were trying both LG Flash Tool 2014 and LGUp or just LGUp? LGUp doesn't work with all devices (not the VS985 Verizon G3, and I don't think my VK810 Verizon G Pad 8.3).
On the VS985, when 35B Lollipop 5.1.1 came out, we could no longer flash older than the 35B KDZ. We could only downgrade from 100% stock on 35B and higher by using our 10B TOT along with the .DLL that's extracted from the 35B KDZ. I don't know if you can get your hands on a TOT for the VK815, they're rarer than KDZs and usually have to be leaked by someone on the inside, I think.
Also, sometimes a different Windows PC makes the difference.
Yep, turns up OK. It starts to connect in LG UP, but fails after a few seconds. The specific driver also fails to completely install.

I don't know if LGUp works with the VK815. It doesn't work with the VS985. Good you Google for and try the LG Flash Tool 2014 I had mentioned?
There's a driver packet for the vk815, but it wasn't compiled right, or something, and fails to install. I may have a shot if a clean version can be found. Flash tool 2014 is reported to not work after Marshmallow is installed. That is true.

If LG Flash Tool 2014 can't flash your older KDZ while you're on Marshmallow, then LGUp won't be able to, either, as far as I know. LGUp doesn't get around stock bootloader and laf (Download mode) limitations.
Is there a TOT for the VK815? That and using the newer .DLL that comes inside the latest stock KDZ is the only way to downgrade from Lollipop 5.1.1 and Marshmallow on the VS985.

I suspect the new dll pack is for LG UP, because Mm update 'closed out' the old flashers.
Shoot! I just realized you may be thinking I want to downgrade. Nope, only wanna clean install of Mm, as mine currently reads as 'modified'.
The other day, I was messing around and got into recovery where there is an option for debug mode! Gonna have to try that to see if anyone will see the tablet. Not sure, but it may be feasible to push the system image via ADB?
Update: debugging mode yielded no change. Guess I'll just have to wait until either Verizon or LG gets their thumb out their ass and develop a better driver file for the LG G Pad X 8.3.
im looking for the same thing, trying to get my vk815 back to stock, its currently rooted on lollipop. the only kdz files i could find are MM but flash tool wont flash them, if i could find an older lollipop kdz i think it would work.
I recently found/installed new drivers/programs, but haven't bothered with them. My tablet still has the mysterious sd ejection bug, despite the latest update.

so did you figure out how to flash a kdz file with the vk815 tablet? if so which flash tool and files were you using, if possible could you please share a link? I have both LGFlashTool2014 as well as LGUP, but the only kdz files I have are all marshmallow, and I could not find a dll file to use LGUP for the vk815.
I played stupid and sent my tablet back to LG to have them reflash official firmware. I haven't messed with it since.

hmm well, i sure hope I dont have to send it back to LG, the root method I used was posted by player911, he also posted a method to unroot, but the KDZ files are no longer on the internet.

Bell D852 LGE AndroidNet Serial/ Bootloader problems? i think

So i had to unroot my phone to unlock my network with the code. no problem done that. i updated to the newest version of the lg software just to test it out figured i could just lg flash tool it after back to stock. unfortunately after i've updated i can no longer use lg flash tool because my phone is no longer registered in device manager as LGE MOBILE but now its LGE Androidnet. the phone still boots and everything works unrooted, but i would like to reroot it and flash another rom. If this was the d855 i could root from here but since I'm on the canadian d852 i have to flash back to stock in order to root correct?
Is the only way to reflash to open the phone short the pins and redo the bootloader manually with willcracker Boarddiag tool? or is there some hidden dll out there that will allow me to flash from my current state.
If anyone has a root method for the Canadian Bell d852 that would work as well since i could just reflash twrp and then install the rom via zip. then just ignore the problem altogether until next time i have to use the lgflashtool. (which should be never since i unlocked everything now)
*Edit* I Should probably add that I'm on marshmallow 6.0 and the LG PC Suite can only see the phone through wireless. it will not see it through the usb so i can't use that to fix it either.
Thanks in advance

For anyone else i did fix this. without shorting the pin. Flashed the stock rom using the LGUP tool. for some reason when i used flashify to install TWRP it thought i was a frenchy so it auto installed the d852g version. but i just flashed the normal version after i got into the recovery. (still works fine just won't let you install any roms until you flash the correct recovery because of version checking)

Help save a bricked lg g3

:crying:
My issues is quite complicated. Please be patient and read on.
Less than a week ago, I bought an LG G3 D855. It wasn't brand new and definitely out of warranty.
It was on the 4.4.2 Os version but I couldn't update it because I couldn't locate the UPDATE CENTER and after some research online, I found out it was because it was rooted. I couldn't find a Supersu application anywhere on the phone anyways but Root checker confirmed that it was rooted.
I downloaded the stock kitkat firmware in a .tot format and I tried flashing using LG Flash Tool for TOT but it failed because "Device version is different"
I checked the Imei online and it stated that the device is a Sprint LS990 but the details embedded in the phone all say it is D855
I checked online and found a couple of posts about this error and one user said he was able to fix it by flashing the actual Sprint .tot with the lg flash tool. I tried that but it didn't work. It still said "Device version is different. Check BIN or dll"
I checked online and found results pointing to a generic .dll file for G3s and I downloaded it but when I used it on the Flash tool, it resulted to an error "CrossDL blah blah"
So I found a Marshmallow kdz file. LGUP won't see my device model so I was able to flash it after editting the software in my build.prop to D85510n.
***I have always changed the port to COM41 in all the steps I used
The LG UP detected my model and it flashed to 100% but got stuck on a bootloop by loading the lg screen, freezing and restarting by it self. It never gets to the homescreen.
I downloaded lollipop kdz reflashed using LGUP in a form of downgrade and it got to 100% and got stuck at the lg screen while trying to reboot.
I redownloaded the stock kitkat rom and used the Lg flash tool but it failed. It said 'PID null IMEI Null"
I used LGUP to reflashed. It came to my understanding that the LGUP can flash both kdz and tot. So it flashed to 100% but got stuck at the lg screen and I have tried all I can but it is stuck. It can go into download tho. I don't know what to do about the IMEI. I don't know if the last flash retrieved it. I don't kniw what to do.
It no longer shows as LGE AndroidNet USB Serial
Please can anyone help me?
I just need my phone to work again. I was stubborn and now I regret it. I should have just stuck to kitkat. I'm so desperate to get my phone working that I wouldn't mind Android Froyo Os if it was ever possible.
PLEASE HELP!!!
I think you have to repair the IMEI...
maybe this can help

I think that he forgot to hard reset after flashing the kdz.
i completly know what you should do:
1: force your phone into qualcomm 9008 mod.
2: use board diag unbrick instruction and it will boot on download mod. for unbrick you will need best kitkat tot for your G3 model.
3: flash best lollipop or kitkat tot to make your phone alive
and then flash it with any kdz you want(it should be for your G3 model)

pls help me
Apparently, it seems my bricked phone keeps disconnecting during flashing process. I dont think it the fault of the cable because I have used different ones and they all seem to work fine with other phones. I have tried a different computer and still the same results. it connects as qualcom 9008 but once I try to start flashing, it disconnects and interrupts the flashing process. my phone just shows a grey screen now when I power it up with the battery in. also, I was trying to upgrade from linear os to the latest linear os. I cant fine the tot out there so im using zv6 currently. could this also be the problem? thanks in advance
