Bricked G3 LS990 with modem restore - G3 Q&A, Help & Troubleshooting

Hi, was having some issues with my LTE through one of sprints mvnos and inTWRP 3.0.2 restored my modem backup from my phone zvc fw( as newly returned from lg support)
I was on CM13 at the time of the incident.
Immediately got a black screen, and doesn't boot or have any indication.
However, the phone is seen in windows as LGE AndroidNet USB. LG flashtool fails with mismatch and will not reset the phone.
I tried the guide below, but it asks for a partition.txt which I don't gave and have not been able to find. I'm stuck.

Any ideas before I send back to lg repair support?
Thanks

Tuesday Night November 25, I ReInstall Factory Firmware For G3 D852 – With Success – Phone Working. Wednesday November 26, I Decide To Root & Install TWRP – With Success – Phone Working No Issues. Friday November 28, This Is Where Sh*t Hits The Fan! I Get Crazy & Attempt To Install ChupaChups Lollipop Rom With TWRP – Seemingly Successful Install But After Reboot Wont Boot Stuck In Fast Boot. So I Attempt To Resolve This Following Other Forum Posts Using FastBootOV – WITHOUT Success – Now When Attempting To Boot Phone LG Screen Comes Up Top Left Corner Says “ERROR Boot Certification Verify” Below That Says “590 Secure Booting ERROR!” Then Black Screen With Flashing Red & Blue LED. I Attempted To ReInstall Factory Firmware For D852 With LG Flashtool Attempt Fails Stating Wrong Model Number – Phone States On Screen Near Bottom Now D855 Ver5.0 Below That D85520A.
Finally Success With Phone December 28, After Countless Hours Trying to Find Some Shred Of Info To Resolve This Including Posting Here For Help Without A Response. I Proceed To Attempt To Reinstall Factory Firmware For D852 - Failed Same Result Wrong Model Number D855. Actual Model D852. I Then Decided F**K It Ill Install D855 Factory 32G Firmware UK Version Why Not? At This Point Phones A Paper Weight In This Time Had To Purchase Another Phone (So I Dont Lose My Mind) - All Available Information Points To Send In For Warranty. So I Do So Again Attempting To Install The D855 UK Firmware Failed To Install Using LG FlashTool, This Time Stating Partition Errors. So I Find After Random Searching & Random Reading Of Everything LG G3. I Find A Generic LG G3 DLL File (LGUP_8974.DLL). Using The Generic LG G3 DLL & Factory Firmware D852 With LG FlashTool - This Time Working Up To 89%, Phone Reboots Shows Large 2, Crossing My Fingers Waiting For The Large 3. What Actually Pops Up Is A Large 0. I Attempt To Reboot Phone Goes To Mini OS, Set Phone To Reboot Normally - AND SUCCESS!!!!!! Factory OS Boots Up, The Usual YADAYADA Setup.
So Thats All, A Long Winded Story BUT Now There Seems To A Cure To Flashing WRONG Model G3 Roms To Your Device.
Hope This Works For Everyone - I Have Devoted Coutless Hours Trying to Avoid Sending My Phone In.
Good Luck!!

Man, this was a long story but I am so glad you have posted this. I always wondered what would happen if I by mistake flash the wrong file (diff model), and now I know. Can you please send me the link to the info and the files, just in case I end up where you were (email: elmspace at gmail dot com), I would appreciate it.
Thanks man. I was just wondering what is going to happen to my LG g3 D856 variant if i flash D855 kdz. Now um not gonna do that. Let's not flash any rom. I successfully rooted and am using D858HK twrp ( yeah D858HK) successfully.
hi hi
hi hi same problem after i want to root the phone my LG G3 D852 my phone stuck on fastboot mode blackscreen ,my pc see it like Android bootloader Interface BUT no other programs see it try lg flash tool or lg repair tool or cmd command nothing they don't see my G3 HELP HELP PLEASE
Sorry for the no response on this problem , got the same problem last year by flashing the d850 rom to a d852 model but this solution is not recommended. It works sometimes (was working with mine but I bring it to LG because the motherboard dies for no reason after one month of use lol) but the installation can go wrong and destroy your motherboard.

Holy hell I ran into the same issue and spent countless hours getting my D852 back to life after flashing the wrong ROM. I found this and sure enough it came back!
plss help

Autorec Bricked my phone, need help

Hi everyone,
It's been some time since I last came here.
I am facing a problem in my LG G3 and was wondering if anyone here can help me.
My phone is D855 was on V21A, Global ROM, rooted. I was thinking about updating to 6.0, so I used Autorec to flash TWRP to backup everything before the update. After Autorec I used terminal emulator (as I always do) to reboot into recovery. And then, the phone kinda died. The screen is always black, no LED blink nothing.
When I connect the phone to the PC it gets recognized as AndroidNet USB port.
I look through the forums for solution and came across this:
http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
I opened up the phone and did the short-wire and my phone got recognized as Qualcom 9008. I used the tool named: BoardDiag and it could copy stuff to my phone.
However, the issue that I faced was that I could not locate the TOT file of V21A. I tried the TOT of V10E and it did not work.
I tried following the method of LGExtract tool to turn the KDZ file to TOT but that did not work either. What happened is that the tool turn the KDZ to CAB and then when I try to extract the CAB it says that it is corrupted. Tried another KDZ from another source and the same result.
What I need now is one of two things:
Either the TOT file of Global V21a
or a working method for KDZ to TOT conversion.
Thanks for any suggestions.
[UPDATE]
I tried renaming the KDZ to TOT but it could not be extracted to the right MBN files.
I am facing the same problem with my LG G3 D850. I flashed a D851 Variant version of the rom and after fixing the hard brick part i am stuck flashing the .tot file because its considering my phone as D851 model. I tried to flash the LGUP_8974.dll to try to fix it and nothing.

Same problem here.
did you find a solution????
Please HELP
.....
I used the same short-wire method and flashed the only TOT I could find, which was 10E. However, this time I flashed the system partition as well. In the guide it says it would take a long time so don't do it. I did it anyway. It took reeeeeeeeeaaaaalllllly long time. Over 4 hours.
After finishing flashing I place back the battery as indicated in the guide and the phone restarted and was stuck at LG screen. I connected it to the computer and it was finally recognized as an LG Android phone.
Then I used the official LG update tool. It detected the phone and said there was an update. I proceeded with the update and everything went back to normal. I even had the same data and apps because I did not overwrite the data partition.
I hope this helps.

LG G3 D855 (6SW) Bricked

My LG G3 kinda died in sleep. It powered off during the night and once I woke up, I tried to turn it off but it's now stuck on LG logo screen.
For a month now I've been going through other threads about this, but still can't find solution that works, I'm not sure if I missed anything.
Phone status:
- It won't boot further than LG logo screen
- From recovery mode, there is only 'Factory reset' option, which I've tried several times, but once again it gets stuck on LG logo
- I can go into Download mode but can't get it to work
So far I've tried with TOT files - LGFlashTool (version 1.5 and 1.8)
and KDZ - LGFlashTool 2014
With earlier versions (TOT files) I got message: Model check information FAIL! - Screenshot: i.imgur.com/N6sxbEt.jpg
And with LGFlashTool 2014 (KDZ) I got: Connection with server fail - Screenshot: imgur.com/wD6vWL3.jpg
While I'm not sure I'm using correct TOT files for my device (it's from Switzerland and has 6SW mark so I went with Europien files), I know that KDZ are good (I've used IMEI search option, so that's all good), but that doesn't even matter since it won't even comunicate with the damn server in the first place.
Any suggestions would be highly appreciated, I've lost all hope :/
Thanks,
Matt
hi bro.
try forcing phone to boot in qualcomm 9008.
and unbrick it with board diag.
for booting phone in 9008 mode you should open back of your phone.
google G3 test point)
on xda you can find few thread about unbrick.
if you couldn't repair it send it to LG Services for repair.

LG G4 help to restore to factory ROM (Verizon LGUS991)

Good day, all
I need help to hopefully restore any working ROM to my LG G4.
Album of screenshots: https://imgur.com/a/3afkFbl
The short story is, I originally saw a slightly newer firmware on the LG site https://lg-firmwares.com/. But I may have installed the wrong one since I now cannot get 4G LTE and I now have a 'US Cellular' splash screen at bootup (as opposed to the original LG splash screen). So I got a new LG V20 and it is now having issues. So I decided to try to go back to the LG 4G IF I can get the right firmware on the phone.
I attempted to enable USB debugging, install the LG drivers, DLL and boot into download mode and use the LG UP software to install the firmware US99125a_00_0317.kdz (not SURE if this is the correct firmware or not but I’m frustrated and starting to not care). However, the LG UP software won't recognize my phone (please see screenshots at link below). I also tried the LG Flash Tool and Uppercut (with the request LG UP version) and neither worked (also see screenshots). The phone looks to be kind of messed up when looking at the status section of ‘settings’ and the fact that it won’t connect to 4G LTE and has the ‘us celluar’ splash screen.
Can anyone guide me on how to fix this (hopefully)?

AS986 Bootloop and Hardbrick

So, I have the LG G4 AS986 which I presume is very similar to the Verizon VS986 but I decided to post here because they aren't exactly the same model. The phone has been working for years but recently got the dreaded bootlooping issue. I decided to follow a few guides to try and fix it by using LG KDZ Tool and LG UP and bricked it. I was able to unbrick the device by flashing some G4 Sprint files using the Qualcomm tool (qfil?). After unbricking the phone, I put the phone into download mode and flashed the phone using LG UP with a KDZ from the Verizon variant. LG UP said it was successful, however, whenever I try to boot the phone, a message pops up with "Secure booting error: 1006" or something similar to that and stays there until the battery is pulled. Somehow, I was able to flash TWRP on the device by nuking the laf partition but even flashing a custom rom on the device using TWRP, it still encounters the secure booting error issue and won't boot. Any help will be greatly appreciated! Thanks!
