LGUP fails to flash LS676? - Android Q&A, Help & Troubleshooting

Hello everyone, I have an LG Tribute HD that fails to flash with LGUP. The firmware it has according to the PC is ZV5, however, the firmware shown when on is ZVB (the system is glitchy most likely because of the mismatch, which is why I am trying to flash it back).
Phone shows up perfectly in Device Manager. Ixhave attempted to switch ports, I've tried almost everything I could think of. Here's the issue: each time I attempt to flash with LGUP (using UPPERCUT since this is one of those devices that do not get properly detected) I get "Error: 0xD, not support diagEnable for laf mode". If I attempt to flash with the latest version of LGUP (1.14 I believe) I get an error stating something about "image is corrupted," as if the .tot file is corrupted (none of them are). Unfortunately it appears there are no .kdz firmware files for this device, so I cannot use other methods of flashing.
Can this be related to the firmware mismatch? I know wiping the system can at times fix this, but there is no way to wipe the system without fastboot (which this and other LG devices seem to lack).
I was debating whether to post this on another LG device's thread, but dedided to post it where it belongs. I don't expect to get an answer as I am well aware that this is a device of no importance, but any help attempt would be truly appreciated.

RIP. There isn't any info on this error.

[Guide] [VS985] Flash Back To Stock - KDZ Method

Updated 2/3/16 Master Download Link Added at Bottom of This Post For All Old and Current KDZ's
This method is confirmed working 100% for devices running 10b/11c/12b/23abc regardless of root/unlock state. While the .tot method is also working on Windows 7, users with Windows 8.1 are having difficulty using that method. Myself and @autoprime obtained a 10b KDZ file that has solved the issue for +10b updaters that couldn't flash back to 10b, so please send him some love for his help and for hosting the file on Team Codefire's servers for all to download. A big shout out to @quangnhut123 for creating the super sweet modified LG KDZ Flash Tool 2014 that makes KDZ flashing an absolute breeze!! He deserves some love as the previous KDZ flashing methods were anything but fun - especially on Windows 8. And another shout out to @deathsquad737 for initially testing the method for our device.
-Please this post and second post FULLY before asking questions!
-First remove any of the .tot flashing tools/programs that you may have already installed as they will conflict with the KDZ flashing tool.
-Download and install the latest LG drivers for your phone here (FYI I am linking the LG site directly instead of the file to ensure that you download the current up-to-date drivers): http://www.lg.com/us/support-mobile/lg-VS985-Metallic-Black
-Download the VS985 10b KDZ: Downloads Located Below
-Download the LG Flash Tool 2014 from this thread here: http://forum.xda-developers.com/showthread.php?t=2797190 and be sure to thank @quangnhut123 for his efforts. Also read that thread a bit so you understand how to fully use the tool exactly, but I will outline the process below.
-Extract the .zip folder to wherever you wish to keep it (desktop, downloads, etc).
-Copy the 10b KDZ file (or whatever KDZ your flashing) into the LG Flash Tool folder
-Power off your phone completely, hold volume up, plug in the usb cable, wait for any drivers to load, and you should then be in Download Mode
-Run LGFlashTool2014.exe (you may need to run as administer as its not an installed program, rather an executed one from wherever you saved the folder).
-You may need to install Visual C++ Runtime Library. If so, refer to the LG Flash Tool thread for more info on obtaining that.
-Select CDMA as your type
-Select Diag as your phone mode
-Select your KDZ file that you copied or pasted into the folder
-Choose the option of CSE Flash (this is a full wipe, you will lose your data). Do not choose Normal Flash when performing a downgrade, nothing good will come from doing that!! Another screen will open, just leave everything the way it is.
-Click the Start button and yet another window will appear showing a language selection screen. Just leave everything the way it is as Korean and hit OK. Don't worry, the tool is already set to flash in English.
-Wait until the Flash is done 100% and unplug/reboot... and that's it - now enjoy your corrected mistake and stop taking OTA's!!!
KDZ files rock, and are nice and easy to flash. No separate DLL files or changing ports either with the tool linked. If any other KDZ files become available in the future I will add them to this post along with any tool or flashing method changes. This thread will be solely kept for KDZ flashing for the VS985. I will also help as much as I can if you run into trouble, though I am not a Windows expert and actually only boot into it when I have to run programs like this....Linux MInt FTW!!

New download link to all KDZ files thanks to @roirraW "edor" ehT https://www.androidfilehost.com/?w=files&flid=35484
-For reference, here's @ins5736 thread for restoring using the .tot method: http://forum.xda-developers.com/verizon-lg-g3/general/restore-verizon-to-stock-t2827878 .
-Also there are reports of the tool deleting the KDZ you copied to the Flash Tool folder after the flash. I cannot confirm this, as it did not happen to me, but to be safe make sure you copy the file to the folder instead of pasting it so that you don't have to re-download the file for future use.
-Please note that the KDZ file we have is build # 10B.01, while the .tot file available is build # 10b.03. The only difference between the 2 files is that the .03 build is the actual released build that shipped with the phone, while the .01 kdz build was obviously a pre-released build. Its most likely some minor last minute changes/bloat added. We can't find any noticeable differences between the 2 builds.
-OTA's WILL FAIL USING THE 10b KDZ FILE WE HAVE due to a signing error with it being a pre-release. The purpose here is to downgrade, unlock, and flash whatever you want. This is NOT to return to an official stock state. You'll need to use the .tot file or the official LG Flash Tool that downloads the current build automatically in order to be in an official "stock" state. The 12b kdz is official and will allow OTA's
*Error Update* So with this leaked LP image, I've been playing with kdz'ing quite a bit and with a new Windows install I got to experience a few of the issues being reported by others that I have never seen, along with trying to troubleshoot some others. Did I manage to fix them easily you ask?? Hell yeah!
USB Disconnected Issue: This is a driver issue. Very easy fix, just download the latest Verizon drivers from the link I posted above and install them without phone plugged in. Power off phone, hold up, plug into usb and WAIT for download mode drivers to install (as stated several times in this thread). Click the balloon to watch the progress, this took about 10min on an i5/ssd machine - be patient. This is the predominant issue I think people are having. The drivers while in download mode are:
-USB Composite Device
-LGE Android phone or LGE AndroidNet for VZW USB Serial Port COM5 (this is the important one)
-CDC Serial or LGE AndroidNet for VZW USB Modem (this will fail if you are on a rom with certain VZW items removed - not a problem, its not needed)
-CDC ECM LGE AndroidNet for VZW NDIS Ethernet Adapter
If driver install fails, manually update them by pointing windows to the driver file you downloaded. I am not going any further here, use Google.
??????'s In The Field: easy, don't change region or language from Korean as stated in the OP. Leave it alone, it will flash in English I promise you. Result = all fields readable in English while running
Connection To Server Failed: Simple, ignore the window. Just drag it away, but don't close it. This is an offline hack originally indented to run online, deal with the window!
Progress Bar: The tool will initially analyze the phone, then when flashing starts, pay attention to the phone screen which will now say COM5. The blue progress bar on the phone is the important one. At around 80% on the tool screen, the phone will reboot. The flash is over and the bar will continue to progress into the 99% while rebooting - then the program will crash. You can disconnect now, you've been successful.
Thanks for the help and the new guide

I'm getting a message saying "Path is too long or file problem" when adding the kdz. Any ideas?

Sounds like your linking the file path instead of directly copying the file right into the folder. Also try checking the file md5 with this one for the 10b kdz file: d228ba692ef0c4704cba0b00fad8b8ce
Don't Forget To Remove Previous LG FlashTool
When I first tried the method I was receiving a message "Path is too long or file problem". So I read through the instructions again. I failed to remove the previous LG FlashTool I was using. Once I uninstalled that program, everything went through without a problem. Thanks annoyingduck!!
I keep getting this and I installed all drivers. Any ideas? Thanks

Some basics to check first:
-Were you in download mode before executing the program?
-When you initialized download mode, did you wait to allow the download mode drivers to load before hitting start?
-Were all steps followed?
-Check cable, and try another one (this is very often the cause)
-Change usb port
-Don't use a 3.0 port, use a 2.0
Thanks for this excellent guide, Duck. Very simple to follow, well laid out, etc. I haven't actually done it yet, but I've got everything in place to do so (the flash tool, the KDZ file in the folder, etc.)
I assume once the downgrade is successful, just reroot with Stump, etc and wait for updates via the community?
Will future updates be available via this flash tool, or will they have to be flashed via TWRP? Sorry, I'm just now getting used to the LG G3 dev community, coming from an old GNEX.
Thanks!
continued error when trying ota
I have a problem. I was originally rooted without a custom recovery. I decided to try the ota and got the error message when trying to install. I then flashed this method (kdz) and got back to stock. I rerooted via stump and tried the ota again, failure. I then rewiped and kdz again, this time I did not root. Tried the ota again, no dice.
Any thought? I can flash the kdz fine and get phone to factory 10b but once I try to install the ota I still get the error.

That's odd... You chose cse flash, not normal correct? Normal would not wipe your device and could definitely be the culprit for the ota failing. While cse mode is a complete wipe prior to flashing.
Correct. I did cse, full wipe. I dont know what's going on. I tried atleast 10 times from scratch. I still cant get the ota to install.

After using the method here to downgrade back to 10b and root. I too wasn't able to then S/W update to 11c using survival mode in SuperSU. I perform the OP procedures again and this time didn't root and still wasn't able to S/W update, kept getting error. So I used ---> [GUIDE][HOW TO][VS985] Restore Verizon to Stock to go all the way back. I'm now able to S/W update to 11c and keep root with survival mode set in SuperSU. I most humbly say that there may be a very slight issue with maybe the files here. I truly do appreciate the ability to return to 10b using this method after updating in the first place!
Thanks, ill try the other method and report back. wish me luck. Either way, a huge thanks to duck for the easy way to rerturn. I just wish kdz worked for future ota. It may be a file issue allowing us to revert to 10b but not then allowing future updates.
Use the kdz method then factory reset the device and see if that works.
I tried that. No dice.

Sorry, I missed this question. Yes, any future kdz's that become available will be updated here, along with any changes in flashing methods. Though it's pretty hard to beat the current tool that's available.
And yes, the idea here is to downgrade to 10b and be able to root, unlock, and flash anything you want. Still unclear as to why some want to take the 11c ota, but that's for another thread. The kdz method here is working where the tot was failing for some, and I personally think it's faster and easier to do than the tot method.
The third step might be clarified. Do you mean something like, "Power off your phone completely, then turn power on while also holding the volume up button..."?

You should probably try it before trying to correct it.....
Nope, power off phone completely, hold volume up ONLY, plug in usb cable...it will auto power on into download mode

Dump contents of entire device (partitions), then convert to KDZ/TOT firmware image?

I have the LG v10 from T-Mobile. I bought the phone a few weeks ago and it had Marshmallow installed. Somehow I managed to install TWRP/SuperSU, but then had issues and flashed the official/stock MM image with LGUP. Afterwards I discovered that MM for this device is not currently rootable, and TWRP cant be flashed via fastboot because MM blocks it. So I returned the device to T-Mo store, lied and said it force-upgrade to MM and had began freezing up. They did an in-store trade for an identical model that had 5.1.1 Lollipop.
The device is currently still in factory condition in every way, with the exceptions that I unlocked the bootloader via fastboot and installed TWRP. Nothing else is modified yet and no custom ROMs have been flashed.
I recently became aware that there is no stock LP image for the T-Mo v10, only MM images are available. After all the issues I've had, I'm now paranoid and want to have a complete dump of the phone's entire contents (partitions, bootloader, system, etc) that is in KDZ or TOT format, and can be reflashed with the standard tools available. Since there is nothing official then I would have to do this myself. This would be useful in the event that I run into lots of issues and need to do a emergency stock restore.
I found a thread by XDA user @tungkick, in which he created a modified dump of the device while it was running LP. However, because it was unofficial and he didn't disclose this upfront, his thread was shut down. His file bricked multiple MM users. I assume it would work if one was still on LP and hadn't upgraded to MM. Not to mention that I cant seem to find his file anywhere. So I figure the safest way is to do this myself. I would be willing to make this file available to the community when finished, with full disclosure that it is unofficial. But the problem is, I don't know how.
I know that the Linux dd command can be used to dump images of various things, and I have read that this can be done on PC by connecting to the device via ADB or fastboot. This would hopefully result in an image file that contained the contents of all the device's partitions.
But another issue would be converting it to KDZ or TOT. And it would have to be done in such a way that it would be flashable with the standard tools.
Can someone please give me a technical understanding of the tools and knowledge I would need to undertake this? Would it be too complicated for someone like myself that has little Android/Linux experience (but is generally competent with computers/technology)?
Thanks for any advice!
Noone can help me with this?
To the mods/admins: I think maybe I posted this in an area where it is unlikely to get any useful answers. Can someone move the thread to the Help& Troubleshooting area of the general LG v10 forum (not here in the T-Mobile subforum)? Thanks!
I think it's just that if that could. have been done someone would have done it already. Even tungkick didn't make one for tmobile for some reason. I think because he made his root injected files from official lg files and lg has not released a kdz or tot for tmobile LP.
Just my observation... I could be wrong.
Sent from my pretty nifty brand new LG V10
@ planetbeen: I don't see why it wouldn't be possible. Linux's dd program can dump almost any connected device that it can see. But then it needs to be converted into a standard TOT/KDZ that can be flashed with any standard software. Which is why I want to create an unofficial backup of the entire phone before modifying it further, so I can do an emergency restore if necessary. I just need the right instructions from people who have the technical expertise.
I had trouble with my old LG v10, I had used LG's LGUP program to flash it to Marshmallow from my PC, only to realize that it couldn't be rooted or have a custom recovery. And I also discovered that I couldn't downgrade to Lollipop. So I returned the phone to the store and exchanged it for an identical model that still had LP. I just told them it had auto-upgraded to MM and started crashing. They exchanged, no questions. Before this I had various issues, like GPS crashing randomly when turning it on, Bluetooth also doing the same thing, and the Settings app also crashed sometimes when accessing the Security menu. I had flashed multiple ROMs, but stock-based and CM/AOSP-based, but kept running into issues, oftentimes the same ones. So I figured that something in the phone had become corrupt and figured that flashing stock MM would fix everything. Big mistake. I'll never let this phone upgrade again until MM is solidly hacked, which from what I've read may be a long time away. I paid enough for this phone and I really value hackability. I'm not the average Joe that just uses my phone for Facebook, etc. To me, if a phone cant be hacked, then buying/owning it is a waste of time/money. Same thing with every computer/electronics device I've ever owned.
Thanks again!
It looks like I'm going to have problems getting answers from knowledgable people, so instead of waiting, I'm going to take a little initiative and at least try to do the dump with dd. I found a post by @tungkick that says to enable USB debugging and make a backup file via dd with the 'adb shell' and 'su' commands. Is the following syntax correct?
dd if=/dev/block/mmcblk0 of=/sdcard/H901.bin bs=1024 count=6291456
Do I run these commands from a PC via command line while connected via USB? Or directly on the device in a terminal emulator? Or do I need to run the command while in fastboot/bootloader mode, while Android is powered down?
Thanks again!
Stock use tool extract kdz then choose file dz (use lgup)
remember can not flash if phone update 6.0
Never downgrade because phone brick now.
version 5.1.1
https://drive.google.com/file/d/0B_Hol5T47S-bQkJVemgzMDV0Nzg/view?usp=sharing
@ tungkick: Thanks for the info. I had used the dd command to dump my phone to external SD before, but the file was 6GB! I was unable to use Tool KDZ Extract to extract the *.dz from the *.kdz file you provided. I was able to flash your KDZ with LGUP, but it boots me into TWRP recovery near the end.
Do you mind if I publicly distribute a mirror copy of your file on my Dropbox, so that it will be available to others that need the stock LP firmware for this device?
Thanks again!
I just wanted to say that flashing your KDZ has possibly screwed up my device permanently. Your image has TWRP, not the stock recovery, and is pre-rooted with SuperSU. Normally this would be good but...............
Near the end of LGUP, the device boots into TWRP. System and MicroSD are mounted, but nothing else (data, cache, dalvik, etc). I was able to obtain a stock recovery *.img, then copied it over to my MicroSD while in recovery. Then I flashed it, booted the phone into stock recovery, and performed a factory reset. Afterwards I booted into system, and all looked good, until it got to the "Checking connection" screen, then a lot of apps started force-closing repeatedly. Because of this I can't get to the Home screen, and no amount of factory reset is working. It just keeps happening over and over again.
How to get out of this mess, anyone?
Help please!!!
Still looking for a solution and would really appreciate any help!
My theory is that the /cache and /data partitions somehow got corrupted during the flash. So I tried booting into FastBoot mode and issueing the commands:
fastboot erase cache
fastboot format cache
fastboot erase userdata
fastboot format userdata
It just says something something along the lines of "remote: cant format/erase in an unlocked state". If I relock the bootloader, it says that it cant erase/format in a locked state.
TWRP still cant read those partitions (they won't mount and cant be mounted), and the apps still start force-closing almost immediately after rebooting into system, before I can complete the setup, preventing me from getting to the home screen.
@ tungkick: Is there any possibility we can arrange a TeamViewer meeting to fix this?
Thanks!

Flashed H901 on H960 - need a comrade to help

Hello all,
In the process of rooting the phone and flashing careless i managed to flash a H901 ROM on a H960 phone. After noticing the horrible mistake i tried to get back to H960 using several methods but to no avail. Here's a list of what i tried so far, followed by what i think i can try next.
1. Tried getting back to stock using this tutorial. LGUP detects my phone as H901 and won't let me flash H960 kdz saying "KDZ file is invalid".
2. Tried using a hex editor on the KDZ file to change any H960 to H901 thinking it might trick LGUP into thinking it is flashing the correct thing. Didn't work either.
3. Tried flashing KDZ file with LG Flash Tool but it says it can't connect to server and stops.
4. Tried updating it with LG Bridge but that also failed (can't remeber the exact error message, but it wasn't anything specific, just something ambiguous about not being able and how i can try to reconnect the phone)
Now, the good parts:
- i still have access to download mode
- have TWRP installed and working
What i think would work is to get a flashable H960A .zip file so that LGUP will see it as it is. Another idea i thought about is to ask any of you who is willing to help me out with a TWRP backup from a H960 model.
If you guys have any other ideas, i'm willing to follow your instructions.
Thank you for taking the time to read about my mess.
Same problem here, really hoping to get it fixed too
Hex editing will work. Can you ss on how you edit it?
@devcon69 Sure, here: https://imgur.com/a/m5dMg are 2 examples of versions i modified in hex(from H960 to H901) all instances of H960 i found were replaced.
Hi all, i finally managed to undo the damage by editing the hex data on a different KDZ file. Either the first time i tried was on a wrong file or i did it incorrectly. The file i edited now is THIS one. I will edit the post with the modified file for H901 in case anyone else needs it.
Thank you all for the help and attention offered
EDIT: https://1drv.ms/u/s!AurbfgIx--Amk0Q7_l6fX60b0T0Y
Hi.i get Error: Error Code= 0x81300302, MD5 checksum error when i try with u hex editored file. Maybe i have to try to download u file again and try ?
Sorry my foult. Its okay now
Could you enlighten us as to the steps you took that accidentally loaded a H901 firmware onto a H960A device?
Loading H901 firmware onto other V10 devices has been suggested as a potential method for unlocking the bootloader of other devices. This seems risky, but I'd very much like to hear reports of success/failure.
Did your H960A have an unlocked bootloader prior to accidentally installing the H901 firmware?
Hi
Can u make a simple tutorial to how we can change the model in the tot file and what app u use to install the firmware?
i have H961N (Dual SIM) and need to install rooted MM but my model still not rooted, just lollipop, so need to install H960a or any other model has a rooted MM.
Thanks in advance.
What you've typed worries me. There are 3 spots in the file that you modified and changing the third could well cause oddities. I would suggest you try running the command `adb shell getprop ro.lge.factoryversion`.
What is the output of that command? If it is a string that begins "LGH960" then my concern isn't an issue. If it is a string that begins "LGH901" then you've still got a problem.
For folks who wish to get this done by computer, try the "chkdzdev" tool from my LGEtools. This is simply a tool to modify the fields mentioned and should make it possible to accomplish this task without a binary editor.

H960A stuck in Splash-screen

Hello,
Today I tried to Root my V10 using this method: http://forum.xda-developers.com/lg-v10/general/root-h960a-tot-add-systemrooted-t3337706
and now it gets stuck while booting. Is there a way to reflash the Original Firmware? (and keep my files)
I tried the "update error Recovery"-Feature in LG Bridge but the download goes really slow and I don't know if it can help me at all.
I hope someone can help me here

Hi,
you should try to flash the appropriate KDZ file with LGUP. There is also the possibility to upgrade the phone and keep the data. You'll find the KDZ file and the link to LGUP (including description how to flash) in the first post of this thread: http://forum.xda-developers.com/lg-v10/general/kdz-download-lollipop-kdz-10c-lg-servers-t3332348.
Make sure you select the correct KDZ file depending on the version of your phone (H960A for Europe or Middle East).

Need to refresh my LG-US998, want to go stock-ish/unrooted, carrier is T-Mo. Advice?

So, I've been having a lot of stability issues on my phone which has been running on a ROM which I flashed back in December of 2019. I'm fuzzy on the details of just what I did back then, but according to Software Info in About Phone it's a Pie ROM, Software Version US99830b, build PKQ1.190414.001.
I haven't had time to follow the LG V30 scene at all since then, and likely won't be able to keep up with it in the future either. So for the sake of stability when I reflash it this time, I don't want to bother with having Root or anything fancy. I have a vague recollection of some LG bloat/spyware that was important to remove for performance/battery life, but aside from that, I just want a stock experience this time around.
Coming back to the forum, I saw the thread about carriers, VoLTE, and ROMs, and while I'm not sure I've absorbed all the important details about that upon reading through it, that's going to be a concern for me as well, so I should mention I'm on T-Mo and plan to be for a while.
So I was wondering if anyone could please point me in the direction of just what steps I should be taking this time around?
Temporarily flash back to Nougat US998 KDZ to erase the effects of Pie.
Then flash to last Oreo US998 20h which is very stable. (I'm on rooted last Oreo US998.)
Use "Refurbish" or "DL Partition" to flash the KDZ. Then you no longer have root.
Your bootloader will still be unlocked. If you want to lock it back, follow these instructions. Do NOT relock the bootloader until you have re-flashed the full KDZ and no longer have TWRP custom recovery. You have to be back 100% stock (even recovery partition) to re-lock the bootloader without bricking the phone.
Personally, I would not do that but at that point (on US998 20h) just reinstall TWRP and Magisk and remove the LG spyware.
LGUP throws an "Error:SPC Code does not match. Please, try again." whenever I try to do anything with it.

You are using the Dev Patched LGUP? Also, which mode -- Refurbish or Partition DL (all partitions)?
Using tecknight's dual mode LGUP, in Dev Mode, and I get the SPC Code error message with Refurbish, and with Partition DL, as well as with other options like Dump, or Phonesetting. (Did not try it with the DO NOT TOUCH options like Chip Erase.)

Good you didn't touch Chip Erase.
Yes, Dev Mode is correct with tecknight's dual mode LGUP.
Strange you are getting that error message with both those modes (Refurbish and Partition DL).
Try this .bat file: https://forum.xda-developers.com/t/...r-instructions.3790500/page-200#post-84374965
If that doesn't work, you may have to try a different computer.
No success with the .BAT, or on the other computer in my household. Still getting "Error:SPC Code does not match. Please, try again." at the 4% mark.
