Bricked D801 - TOT & KDZ recoveries both failing?

I've got a T-Mobile D801 and tried flashing to the stock lollipop rom D80130b_00 using TWRP and the instructions on this page, but the flash must have failed. I did a full factory reset back to stock 4.4.3 prior to attempting this flash and I'm not sure what (if anything) I did wrong for the flash to fail. I can boot in factory reset mode and select clear everything, but then I just see the android guy with gears turning for 2 seconds and the phone reboots again.
Now I'm in a bootloop where I get an "error: Boot certification verify" above the T-Mobile startup logo followed by a "Demigod Crash Handler: Critical Error!" screen that provides options for rebooting (volume down) or putting the phone into download mode (volume up). After using the volume up the screen displays "Volume Up is pressed: Jump to Dload mode" and after connecting via USB appears in device manager as "LGE AndroidNet USB Serial Port (COM41)". I can't (1) boot directly into download mode or (2) get back into TWRP.
I've tried both the KDZ and TOT methods listed in this thread and neither are working. The LG Flash Tool 2014 / KDZ option starts the LG Mobile Support Tool, but it fails every time once "S/W Upgrade is in progress" reaches 4% with a generic "Upgrade stopped due to an error" message.
The TOT method fails every time with a "Model Information Check FAIL!" message. The full text is - "PID: NULL, IMEI: NULL, Model: , DLL:801, BIN: BIN_LGD801AT-01-V10c-310-260-AUG-13-2013+0.tot , SWV: , SWOV: , Model Information Check FAIL! , 00000000"
I've also tried using srktool to repair fastboot, but it gets stuck at "waiting for device".
What do I try next?

Finally got back into 4.2.2 using tot method. LG Mobile Support Tool doesn't think updates are available though??

same situation lg g2 d802

Yes, I *think* what happened was that my 30b bootstack was flashed successfully via twrp, but then the actual kdz flash of D80130b_00 failed. I had a lot of trouble at this point - needed to fix qhsusb_bulk problems first, then use the more aggressive TOT flash method to reset to stock 4.2.2.
Finally the LG Mobile Tool was still reading it as having D80130b_00 / lollipop after going back to 4.2.2 via TOT (?). Last step was to do a full restore from the LG Mobile Support Tool (options -> upgrade recovery) and it actually downloaded / flashed D80130b_00 so everything is working well now :good:
If it helps anyone I used the LG backup tool to restore apps / media and have to say that for a stock solution it's pretty solid.

qhsusb_bulk?

you said your g2 was detected as a lge androidnet in device manager but not as a qhsusb_bulk...then what problems have you fixed about qhususb_bulk? and what is the more aggressive tot method different from this threadhttp://forum.xda-developers.com/showthread.php?t=2432476

Were you able to find a solution? I'm in the same situation. Please help!

Bricked LG G2, download mode goes on, but not working

Hello
I'm new here, I've been modding my lg a few times, always when bricked, kdz or tot files were saving me.
But now I've got real problem.
I was changing ROM from Cyanogen 13 to Cloudy 3.3. I thought I just need to flash rom via recovery (2.8.7.3 bump blastagator). Flashed fine, without any troubles, but when it came to reboot, phone just got stuck on LGs logo.
I knew i f*ed up.
Recovery isn't working, but Download Mode is turning on normally, at least it seems to.
So i tried to flash KDZ, but LG Flash Tool immedently shuts down giving "lg user...." error (don't remember what exacly it was saying).
Then i tried via tot files. But after installing drivers from tutorials, device isn't showed as "LGE AndroidNet USB Serial Port", but as few positions like MTP device or usb serial port(but not in Com ports) and all are marked as devices without drivers. Flash tool for tot also didn't worked here, because it did't found device.
What can i do now? Please help me.
[Edit]
So now, using different drivers somehow Jelly Bean installed by tot method (device didn't appeared as tutorial said, but it worked) phone is booting normally, but i can't again install lollipop with kdz files.
I was trying 3 different drivers, every giving instant error of flash tool.
What can I do now?
[EDIT2] LGUSERCSTool.exe is crashing. How can I install lollipop now?
Are there tot files for lollipop?

LG G2 hard bricked, partition table lost and stuck in QDLoader 9008 mode

Hello Guys, I have LG G2 F320S (Korean Variant) and a few days ago it was stuck in fastboot mode while i was trying to upgrade to Lollipop firmware using LG Flash Tool 2014. And Fastboot commands were working fine but the problem was that some of the partitions had become write-protected so I was unable to erase or reflash those partitions. So, I short circuit the capacitor and I successfully entered Qualcomm 9006 mode with a number of partitions. I used SRKtool to restore partitions (I have this experience in the past so it was easy for me) but here I noticed 1 or 2 partitions were not restored (write-protected) but phone restarted to download mode. When I tried to flash stock firmware then it always stuck in the middle or something and later once again I was stuck in fastmode mode where I started.
I don't know how partitions became write-protected?
Once again I disassembled the cellphone and short-circuit the capacitor to enter Qualcomm 9006 mode and this time, I wanted to remove write-protection from these partitions so I opened "Diskpart" in "cmd" selected LG G2 and performed clean command and format it. Diskpart removed all the partitions gave me a 32GB single partition like a USB Flash. :laugh:
I thought may be after shorting the capacitor, I will get back partitions but this time I got QDLoader 9008 mode. Now whenever I connect phone to PC with or without battery then it is detected in Qualcomm QDloader 9008 mode.
I tried Boarddiag v3.99c but unfortunately this tool doesn't extract .kdz file of my LG G2 F320S korean variant. I tried to extract .tot file of LG G2 D802 (intl variant) and it completed successfully, so the problem is in .kdz file of my cellphone(probably not supported by this tool).
I can extract this .kdz using LGFirmware extract tool but unfortunately it doesn't create "partition.txt" file which is required in boarddiag to flash partitions. I used partition.txt file of LG G2 D802 but it gives error : No DLoad mode when trying to reflash programmer".
Any help would be appreciated.

Boarddiag full and working version helped
I have tried a lot of times to flash the partitions using boarddiag but it failed. It was the problem of the software because almost all versions had missing files. At last, I have found a working version of boarddiag which detects my phone and I am able to flash boot partitions to it. Although all 3 tests completed successfully (AP, EMMC, SDRAM) but still I am stucked, even after flashing all the boot images, I am still stuck in QDLoader 9008 mode and whenever I connect it to PC (with or without battery), it is detected in QDLoader 9008 mode.
Here is the link to the full working version of Boarddiag 3.99 for LG G2:

(mega is blocked in many countries so you may have to use proxy/vpn to open this link)

Here is the result of all 3 tests. Please tell me whats the problem. SDRAM result is FAIL but why so?

Now I am able to enter "Download Mode" but unable to flash stock or any other firmware. I tried flashing with 2 softwares:
1. LG UP-G2-G3....This software gives error at 6% (at LAF read) as shown in picture below :
https://ibb.co/zXpDcjt
2. LG Flash tool 2014.... This software gives error at 4% by saying "Unable to Establish Connection" though connection is fine because phone is detected in Device Manager and in Download Mode "It shows signs that communication is successful but it wont flash.

Did you try the TOT flash method already? It worked best for me, when I restored my phone from scratch 2 days ago.

Dear I have tried two methods. I tried LGUP and LG Flash Tools 2014. But both fails. Unfortunately, no TOT file is available for my LG G2 because its Korean variant (F320S) and it has only .kdz firmwares available.

QDLoader 9008 mode
Now, my phone is not entering download mode. It is displayed as QDLoader 9008 mode when connected to PC. Check the screenshot here : https://ibb.co/yk3VSbS
I have the working version of boarddiag but sometimes it passes all 3 tests and sometimes fails EMMC test ad sometimes SDRAM test is not completed successfully.
