Hi Gurus,
My wife handed me her phone and said it wasn't working. For a few weeks she's been having issues, i.e. overheating, apps closing, etc. I'm not sure what version she was on or if she even took the marshmallow upgrade or not. I do know that her phone was stock. She wanted to take it in or send it out to be repaired, but I told her I could get it working again. Turns out everything I try keeps failing so I need your help badly.
Symptoms at the moment:
- Can get into download mode for a brief second while connected to the computer. After plugging in the phone to the USB cable it'll go to download mode, then the screen will go to firmware update. In device manager it briefly shows up under Ports as LGE Androidnet USB (or something like that). After about 20 seconds the phone disconnects, reconnects and shows as Qualcomm HS-USB QDLoader 9008.
- Am able, only after a battery pull and waiting 5 minutes, to vol down + power and get to recovery screen. If I try to to a factory data reset from there the screen turns off and nothing happens.
Things I've done and tried -
- Updated drivers from LG specific to VS985
- Downloaded all needed files for TOT method (VS98510B_03.tot, LGUP8974.dll, replaced Megalock file)
- Downloaded all needed files and tried to run LG Flash Tool 2014 to do KDZ method. I got it started but as soon as my phone switches from LG to Qualcomm in device manager it stops. Can't run it while the phone shows up as Qualcomm.
- Downloaded BoardDiag3.99 and tried to get the driver to show as LG instead of Qualcomm - Can't get anywhere here either.
Help!!!!

Did you try the QHSUSB_BULK 9008 mode recovery method? Just Google it.
The method's the same on all devices, just needs the special driver, you to put windows in a non-signed driver enforcement mode and the 10B TOT.
Boarddiag 2.99c or 3.99 might help you, you have the tot file - it's half of the job already. Look through links in my signature

Ok, I can get the phone to show as LGE Androidnet USB now, but only after entering download mode after it causes a kernel crash upon startup. It's either a green kernel flash screen or a different kernel crash screen. I can get the phone to boot into a screen to recover via adb, sd card, etc as well.
I'm just looking to return the phone back to stock marshmallow. I'd prefer no root, just a total stock phone again for my wife to use.
The more I read the more I get confused on how I should proceed. Any clues?
Thanks

Judy ignore anything having to do with rooting or putting TWRP on, or flashing a custom ROM.
After flashing the 10B TOT, use @annoyingduck 's stickied return to stock thread on the General section to flash the 48A KDZ to be up to date.
Note that I've had the experience lately that I can't flash the 10B TOT until I flash a KDZ first. So if you have to, flash the 48A KDZ, then 10B TOT, then 48A KDZ again.
TOTs fix things that nothing else does, so that's why I recommend it in there somewhere.

Hey guys, I seem to have soft-bricked my E970 (which was running stock ICS) in the process of trying to get the bootloader unlocked using Freegee's ZIP method.
I was able to get into Download Mode, so I got LGNPST installed and flashed a TeenyBin, but 85% through the process (after the reboot) I got an error from LGNPST about the device disconnecting along with a Windows "USB device not recognized" notice.
I was able to get reconnected and complete the flash (100%), but my device still didn't get past the LG logo. I figured the interruption might have screwed the flash up, so I tried it again, but I got the same error, only this time I wasn't able to complete the session, and now my device isn't being detected in LGNPST at all
Am I SOL? I can still get into Download Mode, and my device is still showing up in Windows. Any suggestions? What are my options if I can't get my device recognized in LGNPST anymore? I dug around on the forums but couldn't find a solution.
Quick update: I tried following this guide to unbrick my E970 without having to use LGNPST, but am unable to download the KDZ file for my phone since I don't have a way of getting the serial number. I got the IMEI from my carrier but no luck there either.
Anybody?

Finally figured it out with some help at the freenode IRC chat. I reinstalled LGNPST from scratch on a clean Windows 7 install and LGNPST picked up my phone like a charm. Must have been some kind of driver issue. I ended up flashing the Teenybin ALTbin and then the latest stable CM10, along with a hybrid 84/27/84 radio to fix some call issues.
I was running a MarshMallow update for the last 6 months and suddenly today morning I just decided to flash the "rootedsystemh960a.tot" from one of the forums here at XDA. First it did flashed the ROM using LGUP but then the Phone was stuck with LG LOGO for minutes and then I flashed it again with my stock UAE MM 6.0 ROM. It did work. Then I reflashed again hoping for the ROOTED ROM to work on my phone and ever since LGUP is giving me this error code with a message " lgup error code 0x2000 invalid command response" and it keeps crashing. Now I have tried to switch windows and tried to flash many ROMs and it wont stand a chance. Why this error message is coming? Can anyone of you experts figure this out? Even the COM ports are matching at LGUP and in my DEVICE MANAGER. Please help me. I am stuck with this mobile. ...:crying:
Little info about my phone. It is a UAE/DUBAI Variant of LG V10 - H960A, and officially I am not allowed to unlock my BOOTLOADER by the LGE itself. I had tried before bootloader unlock modes.. Anyways its not the point here right now.. The main thing is LGUP is crashing again and again.. Is there any other utility in place of LGUP for flashing LG ROMS ????
Well that .tot file was for Lollipop only that was your mistake in this probably and it has corrupted your system somehow. I'm afraid I have no idea how to deal with this phone as I don't modify this one myself because of the lack of development/devs.
I think there is something called LGFlashTool also.

Even flashtool aint doing a job.. When I try to run Get device info from within the LG FlashTool, the application crashes...God! Cant they develop some stable running apps for their customers?
Hi,
can you enter the download mode on your V10? Then it might be possible to flash a clean (unrooted) MM via LG Bridge. Some time ago I tried to install the latest MM Version V20e on my V10 with LGUP. For some reason that failed and left me with a phone without ROM, too. Afterwards the V10 was not recognized by LGUP anymore.
Luckily I was still able to enter the download mode manually. So I connected the phone to my PC and started LG Bridge which still did recognize it as a V10 H960a. So selecting Firmware update and then clicking in the bottom right corner of the window on a link saying something like "repair flash errors" or "repair update errors" (I'm currently at work and cannot check) did a complete clean install of the latest firmware.
Maybe you're lucky and this works for you too.

Well hello, I found the solution for my problem and I was able to flash the ROM successfully. Its some kind of new utility amalagamated with LGUP and it does flash without any problems. Found out it was related to some corrupt dll file or incompatible file I had in my LGUP library for the ROM FLASHING to fail all the time... You just read this first post on this link and you will be all fine. Trust me ...:highfive::good::fingers-crossed::fingers-crossed:

Just dont forget to follow the rules exactly as mentioned and if you can run it in the Virtual Machine I would prefer you to do that but you have to do everything like installing LG DRIVERS + LGUP + LGUP DLL FILE + UPPERCUT as mentioned in this post. Because if you are running antivirus on your PC, it will detect this UPPERCUT TOOL as some trojan horse or some kind of malware. I did that in my VM as I already had my VM configured for my LG V10 Flashing process.
Do it and do let me know should you encounter any problem. May be I can help later on.
I have been pulling my hair out trying to figure out how to get my phone to flash the stock KDZ.
The other day there was a stock zip that I could flash and that would allow me to keep TWRP installed if I flashed Magisk just afterwards to keep the new boot image but with TWRP. Long story short it did not work out in the end. My phone continuously too no end bootloops over and over again. I get the error code:
Boot verification Fail!
-cause : MISMATCH_SIG_Len
The only thing I am able to get the phone to do differently than that is if I plug it into a computer and hold down the up key which will get me into Download Mode. I have all the appropriate drivers installed but the device is only recognized as LGE AndroidNET USB Serial Port (COM3) I think I switched it to COM3 though.
I installed the LG Flash Tool 2014 and the appropriate KDZ for the device but to no avail I am unable to successfully flash the image back.
I had to flash stock KDZs with my old LG G3 and it worked flawlessly. Now this is reporting that there is no IMEI or something. I'm trying to pull the information off of the phone but it's not even doing that anymore.... so I'm not too sure what information to give you.
I just bought this phone not too long ago! I refuse to accept that it's fully bricked I don't believe in that unless that motherboard inside is snapped clean in half. I'm sure there are ways of fixing it.... I just don't exactly know how.
If anybody can help at all that would be greatly appreciated!
I was just getting back into having a rooted phone and miss it dearly already!
Thanks!

P.S. Any feedback at all is appreciated! I HAVE to fix this!
this trusty little phone was rooted on xdabeb 3.1 for the last year and never failed. recently 2.4 ghz wifi stopped working but 5ghz worked fine. I noticed bluetooth stopped working and the macadress of the wifi adpter was 020000000000 . today 5ghz wifi stopped working so it decided to do a tot to 10b and start over since i read it does more than an average kdz. the tot failed at the end on the check. and phone was bootlooped on lg logo. I downloaded the debrick kit and skipped qualcom usb section and went to kdz cause i could not download the usb drivers. link was gone. phone is up but wifi is same as above. sound like hardware? hope not. any insite would be greatly appreciated. and thankyou to all for unbrick kit.... at least I have a phone to answer and get texts tomorrow.
in the first step during the 10b tot I noticed xdabeb name come across the screen during firmware upgrade display log as one of the variable...

all ideas greatly appreciated
okay so I got a little frustrated and said f-it and took the ota from vzw... prolly not worst decision this week but it's definitely near the top. that created a phone with a successful update but a failed one it keeps asking you to do a system update every reboot.
I downloaded hs-usb drivers and opened up the phone and got it into 9008 mode with loaded driver... flashed all partitions and all were successful. went to use the lg flashtool and it actually has hung my win7 computer like 4 times at around 28%.
note: when the lgflashtool would run it would show ????????usb?????????????? and a lot more question marks. since I did flash it once with the tool and it worked kinda wondering whats up. any way to dump a partion table from this thing to post?
Referring to this thread https://forum.xda-developers.com/lg-g2/general/mega-tut-how-to-fix-bricked-lg-g2-t3055033
I have found a shorter method of unbricking your LG G2 after troubleshooting uppermentioned method for quite some time with no result.
Your phone is stuck at boot in Dload>Download-Mode>Fastboot, mine is LG G2 D802
Your phone will not do Hard Reset when entering recovery and selecting Yes
Windows 10:
- First Install LG G2 Driver. v4.x works fine, I tried many and didn't have any problems in that regard, drivers all work fine
- Download LG Flash Tool 2014, not the fancy new one, but this old version
- Find the most accurate backup .KDZ file of your phone's OS, mine is EU16GB, and the file that worked for me was D80230d_00.kdz. Flashing the wrong rom will result in bootlooping that can be fixed by restarting the process.
1) USB connect your LG G2 in Dload/Fastboot to your PC
2) Run LG Flash Tool 2014 with DEFAULT SETTINGS, press select KDZ file, find the KDZ OEM ROM you found online that matches your phone perfectly, select Normal Flash and click Start
3) Your phone reboots into Firmware Update
Firmware update is the flashing process happening
If it fails you can try again by restarting your phone, or try another KDZ ROM
4) Once the flashing is done the phone restarts itself and boots into the OEM OS
5*) if unsuccessful try a different .kdz, personally I had to try three of them ,_,
i pulled these steps from my memory, i try updating if something is wrong
If I may ask, what do you mean with "1) USB connect your LG G2 in Dload/Fastboot to your PC"?
Could yoiu please elaborate what "in Dload/Fastboot to your PC" means?
