LG K4 (120E) trouble

Hello there! After many hours of searching on sites dedicated to smartphones, I could not find anything close to the problem that I have. Specifically talking about LG K4 (120E). I tried to root, but failed and now the phone is locked in secure booting error 1003. I tried factory reset, but to no avail. No Download Mode, just Fastboot mode. ADB tried but can not find TWRP .img for this device. Not find any KDZ file for that device. I tried on several websites, but once inserted in the box search IMEI, announced that there are no files for this device = Nothing found. My request, for those who are more experienced or who greeted me with the same problem as this device, share links where you can get TWRP or KDZ for LG K4 (120E).
Thank you to everyone who can help me

LG LS665 (Tribute 2) Virgin Mobile Hard Brick

Hello, I have a bricked Virgin Mobile LG LS665; here's how it happened
The LG LS665 recently got an OTA update. However, my phone was rooted, so I could not apply the update. The patch was failing because some of the system partition files had been modified. I found out that the original versions of the modified files had been backed up by the tool I used to root my phone, and thinking myself clever, I restored the original files, and applied the patch. Of course, this didn't work, and my phone got stuck at the LG logo whenever it tried to boot.
When I tried to boot it into recovery, it would give the error "Secure Boot Error 1006" and reboot to the LG logo. From what I gather, this boot error comes from the bootloader not recognizing the boot image. Dang. Not one to give up, I searched for unbrick solutions for the LG LS665, and found some. Unfortunately, the only methods I could find were for the Boost Mobile version of the phone. Reckless as I am, I decided to try the Boost Mobile unbrick process, but only managed to brick by phone harder. As a new member, I can't post a link to the unbrick process, but it involved flashing a .tot system image with LGFlashTool. I may be wrong, but my research leads me to believe the process failed because the partition tables for the Boost Mobile version and Virgin Mobile version of the phone are different.
Now my phone will not display any boot screen; I can't get it into normal, recovery, or download mode. When plugged into my computer, Windows device manager lists the phone as "Qualcomm HS-USB QDLoader 9008". Googling that device name brings up a few tutorials of how to revive devices in this dire state, but none that seem to work without a correct system image. I believe it is possible to unbrick my poor phone, but I am not knowledgeable enough to figure it out on my own. If anyone with a clue what to do is willing to help me, I would be very grateful.
In summary, what I think I need:
Some sort of system image for the Virgin Mobile version of the LS665. (I think a .tot or .kdz file)
A kind, knowledgeable soul to point me in the right direction
Thank you for hearing my lengthy plea,
Grant Moyer

LG G5 H850 Bricked ?

Hi I messed up with my LG G5, help needed ?
I want to tell u what i did until now.
I want to root my phone:
1. Unlock Bootloader.
2. Install TWRP
3. Messing around in TWRP becaus i dont finde the SuperSU files cause of encryption usw.
4. Want to Swipe all data and start all over again
5. bootet my device normaly and ther is just the Message "Your device software cant be checked for corruption".
I cant do anything now. I tried to factory reset the phone didnt work. The phone doesnt react to any CMD commands.
I cant enter the TWRP.
I used LG UP to flash the device but LG UP doesnt recognizes my phone correctly, neither in USB Download Mode or in the so calles status, where i just got the blackscreen with the Message"Your device software cant be checked for corruption".
Maybe you guys have a solution.
PS. Sorry for bad english
as long you can start into download mode, your device is not bricked.
this thread should help installing and using LGUP correctly.

there is an answer by autoprime to your question

The unique programmers required for the G5 for BoardDiag to work are not public so forcing your way into 9008 won't get you anywhere.

with 9008 he means qhsusb_bulk. The drivers you will need are from Qualcomm, once BoardDiag files for G5 are public.
were the boarddiag files ever made public?
Facing the Same problem
I am now facing the above mentioned problem. My g5 h850 doesn't do anything and the only sign of life there is when i connect it to my PC and it picks up as Qualcom hs- usb Qdloader 9008 other than that no display no sound from the handset whatsoever tried getting it into download mode but it won't show anything. I installed all the drivers and tried connecting with lg up but it doesn't pick the phone on any com ports. Is my phone completely damaged or can I do something to bring it back to life. Please help someone
qfil with firehose or octoplus may solve your problem
Can't find the required files anywhere

QFIL needs PrimaryGPT_0.bin file through firmware extractor but no matter what stock firmware i extract I get multiple patch files like PrimaryGPT_0.bin, PrimaryGPT_1.bin, PrimaryGPT_2.bin, PrimaryGPT_3.bin .......PrimaryGPT_7.bin and when I try to get them through emmc it won't recognize any of the GPT files. That's the step where I am stuck plus I can't seem to find the mbn file for H850
I have lg v20, I too hardbricked my phone, when I extract any kdz I got 7 gpt files. primarygpt0 to primarygpt06 as you said.
are you sure we only need primargpt0 to flash via qfil? i think we need proper firehose/ programmer file and rawprogram file
Maybe I hard bricked mine:
Flashed with uppercut in download mode but with every KDZ file in UPGRADE mode I tried , after the second lg logo with sound of wellcome, it freeze and reboot over and over, it seems that crushes in infinite bootloop. Is this hard bricked?
no, this is not hardbricked. atleast you can enter into download mode.

Help with Hardbricked LG K7 phone

I have a LG K7 MS330 whose software was not working properly. Looking for a solution, I found that there were several firmware updates of this terminal (I had the version 10e compilation), which basically consisted of more recent versions of compilation distributed in kdz files. I proposed to download the latest update available ensuring I download the file corresponding to the smartphone region (MTP in my case).
So, I downloaded the file MS33010k_00_0405.kdz, the tool LGUP 1.14.3 and the file LGUP_MS330.dll version 0.1.2.7. I connected the phone to the PC and started the process.
At 99% the installation failed. However, I could still enter in download mode. So, I download an older version, the MS33010h_00_1021.kdz and repeated the process. This time I got no error.
However, when I finished, my phone went into hardbrick mode. Check the battery and no problem, even charging perfect inside the phone. I do not think the device has any problem with hardware as it worked before. The only life signal I have now from the device is connecting it via USB to PC and press the VOL +, VOL- and POWER buttons simultaneously. In this way, Windows recognizes it as "unknown usb device".
I would be grateful to anyone who can help me with this problem. Regards
I have the same problem!! Please!!
