Lg up tool Device model unknown? - T-Mobile LG G4

My g4 is in a state of half alive half dead.
I explained in another post my issue.
Seemingly people say lg up tool is now the only method Unlike the old flash tool method to unbrick or kdz stock is this Only cause of 6.0 firmware?
When i plug in phone to pc in download mode Lg up tool shows device model as unknown. And says please select a device model which theres no butons to do that.
Lg flash tool 2014 won't flash 20i kdz it errors out connection upon extracting kdz software at around 80% Even leting it sit don't work like people say to do
Ive tried 10n kdz also that says software upgrade in progress fails at 9% then says unplug phone from pc and retry.
There is no Com in the download mode screen at any point.
All i did by mistake was fastboot oem relock bootloader Whilw rooted and on micromods Rom ONLY cause i wasnt sure if that' was the cause of the failed Flash tool errors. Now i have secure boot error 1003. Now I knew that was a No no with Nexus phones but i suspected Lg kdz over writes all that stuff.
Theres gotta be a way with one of the 2 tools Or a way to adb re unlock the bootloader and maybe salvage my Underlying twrp recovery and O.S
ANY HELP HELPS

LG G Flex F340L Korean variant bricked

Need help to unbrick my LG G Flex F340L software version f340l20b. It was rooted using towelroot. later I installed SuperSu app. But due to this OTA update was not installing. once downloaded during installi it was giving an error like "Your device is suspected in rooting. System update is not available for rooted device".
Later I installed flashify app from play store and tried flashing CWM recovery. Once recovery installed, phone tried to reboot to recovery where I got Secure booting error message. But the most terrible thing happened immediately after that. During that time OTA update downloaded once again and started installing. immediately after reboot, my phone is stuck in below screen. Now that its almost 3 days, my phone is in the same state. Even if I connect it to PC, though it seems that the phone is switched off, in PC I can see quite a few disk drives prompting for formatting those.

Thanks for sharing similar experience in a different thread. I installed CWM in my LG G Flex f340l20b. Once after that, while OTA update getting installed, my phone gets into this situation where there is no download/recovery mode, only LG logo comes in the screen along with security error. phone is getting detected as qhsusb_bulk and getting too many disk drives asking me to format those.

Do you have tot or kdz file?
You can extract these file from kdz or tot.
Only 10 files are needed

Thats method is too clear.
1) U need 10 files aboot, boot, laf ,dbi ,sbl1, rpm, tz modem, recovery, misc.
U can extract these file from tot or kdz using lg firmaware extractor.
Note....kdz doesnt have misc file and it doesnt matter so dont worry
2) you need to install qualcomm driver and if yellow mark then disable digital signature enforcemt.
3) copy these file to unbrick very partiton tool folder.
Note..
If u extract these file from kdz or tot then these file files will be in .bin format then you need to simply rename the extension from.bin to .img
4)
See the disk managemet on your pc and find which disk no. Your phone showing.
If showing disk then run 1hardidsk.bat/exe
If it say disk2 then 2hardisk.bat
5)
Keep in mind.
D802 d800 d801 d805 d803 all have same partition table for these 10 files.
So if u dont see any model in the kist choose d800 or d802..
After its says continue close the window
And swithc off your phone by long pressing power button for more than 15 second so that phone turned off.
After turned off press and hold vol up button and conncet to pc.
If you stuck in download mode screen and didn't get firmware update screen
Then do this trick.
Switch off.
Press and hold vol up and connect to pc.
As u see download mode scree.
Keep pressing vol up many times
Around 30 times.

Unbrick LG G4 H811

Good night guys.-
I wonder if there is any solution for brick G4 for this version , since I have seen it is releasing some files from multiple versions except those to remove the brick my device.
Thank you
It depends on how you bricked it and what state it's in.
Does your phone turn on?
what's on the display?
when you plug it into a computer does it show up as a device and if so what kind?
what did you do to brick it?

the screen or the LED is not lit , the pc recognize me as " qhsusb_bulk "
I don't think we have a fix for qhsusb_bulk yet. sounds like you flashed a boot loader for a different device.
I Fixed it on my H811. For those who need help, i have written the thread
Visit http://forum.xda-developers.com/tmobile-g4/general/lg-g4-h811-complete-unbrick-guide-100-t3461629
I need help please.
I have a H811 T-mobile LG G4. I unlocked the bootloader, flashed TWRP, flashed MM-20e Global rom which is ported rom from H815 20e. Everything worked well untill I deciced to relock the bootloader! I have issued a command fastboot oem lock and the device began to bootloop. "Secure Booting Error, Error Code 1003, MODIFIED".
I Have tried LG Bridge but it says "Can't check internal storage".
I Have tried LGUP with several kdz files including H81120o but it says "Invalid kdz file" (LGUP sees my device as H81520e now)
I have tried LG Flash tool and nothing works.
Your help would be highly appreciated.

H811 stuck in bootloop, No recovery

I had messed up a couple settings on the custom ROM I was running. I wanted to get back the stock setting so I went to recovery and did a wipe. I rebooted and found I lost supersu. I went to reboot back to recovery to flash supersu and It wouldn't boot into recovery. I went to adb on computer and couldn't reboot it there either. I found I could put the phone into Download mode. I tried the flashtool and LGUP and neither will communicate with the phone to be able to flash stock firmware. I don't mind too much because I can JUMP, its just the boot animation says Xperia.
ADB commands only produce "Waiting for device"
Flashtool says, "Wrong dll file"
LGUP won't let me use a current KDZ but only a tot file and the only one I found is 10n.
Relevant thoughts welcome as I continue to scour these pages.
Apparently LGUP considers going from 20r to 20p and upgrade. Lesson learned. 1) When your phone is bricked playing with other tool settings can't hurt anything. 2) Sometimes the OP of a thread can be a little ambiguous, read and reread. If one thing doesn't work, check for (possible) variations.
I was using refurbish setting on LGUP because that's what seemed to apply.

Bricked H811 (Error 1003) while on Genisys, cannot use LG tools to restore from KDZ

Well I was dumb today and thought I'd see what happens when I go and lock the bootloader on my tmobile G4 with Genisys 4.9 installed. I was going to replace it anyway it was giving me issues. it started bootlooping with error 1003. No prob, I bricked this thing before. But now LGUP will not recognize the model. Model is Unkown, and COM Ports are COM4, Genisys. I've tried just about everything I can. I think my issue is that LG isn't seeing my device as a H811 so it won't let me force it to restore. Are there other ways that I can restore, since I can get into download mode?

Yeah, see the problem is that LGUP isn't reading my h811 as itself, just saying unknown model so I can't flash with itg
So to go more in depth and kind of bump this thread, I cannot enter recovery. I can get to where it asks me twice to confirm resetting but instead of entering twrp it goes back into the LG bootloop. My biggest thing is I need adb, but I can't figure out if I can access it on this device, since I can't boot into the OS or recovery. I think the custom rom I had on it, Genisys 4.9, changed the model number in build.prop so the LGUP tool only sees it as an unknown model. If I could just force LGUP to think it's the H811 it is then I could probably flash it. LG Flash Tools always get frozen at the network part. Well since the entire problem came from my using "fastboot oem lock" while on a custom rom, so I assume I just need to "fastboot oem unlock" to fix it. God this has been such a pain

[HELP] Looking for last (or any) ota update.zip for D415

Hi everybody
I need to find an update.zip to flash it on stock recovery and attempt to repair the phone system.
Long story short..
I restore my D415 (previously with Lineage 14.1) to stock firmware (KK) via KDZ file and LG flash tool, then update it to LP with LG Mobile Support Tool and everything was good, then i tried to root the device with the LG OneClick Root (which i used several times before to root my phone without problems) but i don't know what happened during the batch process and now Download Mode has been replaced with Fastboot mode and the device hangs on the T-Mobile startup screen, so i can't flash a KDZ file again to restore the phone without a Downlaod Mode. The fastboot mode throws "remote: unknown command" with every command i tried (except fastboot getvar all; which shows "unlocked: no") even reboot doesn't work.
Tried everything even booting on Qualcomm Qdload mode (shorting the phone with test points) to reflash the firmware files but couldn't succeed because QFIL, QPST Software Downloader and BoardDiag they all threw errors.
I can access the stock recovery mode by pressing home button when the "erasing" screen appears after selecting "yes" on factory reset menu, so i need an official update to try to fix this phone, don't know if its gonna work or if this is a hardware issue but at least i want to try. Buying a new one is very difficult for me right now.
Thanks for any help.
