I tried to flash my H901 but failed.
I cannot recover it in any way.
When it turns on it loops on the LG logo and a message: boot verification fail!
On Hard Reset it keeps looping on the same screen
On LG Bridge there is a message: Cannot check internal storage on your phone
On LG Flash Tool with H90120e_00_0316.kdz: error connecting to server
On LG UP with TotbypassFRPlgh901.tot: Antirollback version is smaller than device version
On fastboot flashing stock boot.img: writing 'boot'... FAILED (remote: unknown command)
I don't know what else to do, please help!!!!
lg bridge cannot check the internal storage on your phone
It sounds like my H901. You may have inadvertently did what I did on purpose and that was to re-lock the bootloader. After the fact I read that one should NEVER re-lock the bootloader or else they'll end up where we're at. There is nothing to be done at this point, no fast boot, no LG UP, no LG Bridge, nothing.
Found the cure!!!

Hey! I found this link with the real stock firmware for Marshmallow. I installed it with LG UP and it got past the 9% and installed fully and now my H901 is up and running again. http://forum.xda-developers.com/tmobile-lg-v10/general/stock-h90120j000712-kdz-t3436249
I then found this one http://forum.xda-developers.com/tmobile-lg-v10/general/root-android-6-0-h901-t3382819 and updated with LG UP and now I'm rooted; the phone is no longer bricked and everything is working great. Titanium Backup is back!!!
You guys are trying to downgrade v20j perhaps which will give error or brick your H901. Don't do it, make sure you are flashing KDZ of v20j only. And btw, re-locking bootloader does not brick your device. I relocked 3 different H901s while on V20j.
Greetings, I tried flashing my LG H440F to its original state via LG Flash Tool.
At the time being it was stuck on 1% and after several errors I desisted and tried another KDZ to flash with same result (stuck at 1%)
Now the phone is stuck in "fastboot", I can't boot it to Download mode neither do a Hard Reset as it does nothing.
Adb does not recognize the device and fastboot always throws a FAILED (remote: unknown command) when trying to do anything.
Did I just entirely brick my phone? If so, how to unbrick it?
Best regards.

Second Bump! I found out about flashing with Qualcomm drivers directly to the mobo of the phone? Any ideas?
Hey guys, help.
Playing with dd commands i have now this situation :
I can boot on stock Android OS but it seems i have lost my Download Mode ( corrupted LAF partition maybe...) and Fastboot mode no more here. Stock recovery on my device and no more TWRP and no more root.
If i try to reboot to Download mode or Fastboot mode device it bootloop on LG logo.
How to recover LAF ? i can only boot on Android and OTA are no more available for my device because i have unlocked my bootloader and bootloader is still unlocked in this fu'ck of situation...
Since your bootloader is still unlocked, just reflash laf and recovery. Extract laf from your KDZ and grab a copy of TWRP:
fastboot flash laf laf.image (this will get you download mode back)
fastboot flash recovery twrp.ver.whatever.img
EDIT: Sorry -- missed the part about you saying you have no fastboot mode. With the phone off, have you tried holding vol down and plugging the USB cable in?

yes sure, just tried all possible manual method to have back fastboot mode or download mode but only have LG Bootloop logo.
i think only hope is someone who release a user root method ( temporaly or tethered too) so i can rewrite LAF from Stock OS

What happens when you try to flash stock firmware with LG UP? You just let LG UP enter DL mode for you, don't try to manually enter it. Does it bootloop too?

sure, same bootloop problem, it seems that LAF is corrupted
Damn. You seem to be pretty screwed. No fastboot and no LG UP flashing. You're left with RMA or just sell it, get a new one.
i think that can be still fixed....
Only need of a temporaly # Shell method or tethered too, just to reflash back LAF

Can you get to download mode? If so you can flash back to stock using lg bridge or lg up. The choice is yours on that one but if download mode doesnt work. well that's a tough situation on your hands.

May I know what other model did you try to flash to your H932, and what mode is your phone status now , can you see com port on your PC device manager, is it Qualcomm HS diagnostic 9025?
Hi @car2carl @R800x_user
I used H932 and i try to flash H930 ( because in H932 there is no my national lang. so i try to flash with H930 UE version )
For the moment working only fastboot mode phone got boot loop on LG V30 logo, that same situation is with download mode, its start but after a few second phone restart...
So i'm in deep sh..t because in europe LG company / repair services rejected my request for repair even for a fee ( because i unlocked bootloader ) becasue phone is brought in USA
I try to flash but all every body know in H932 fastboot commands are cut off ..
i try fastboot flashall command but without success
Also i was play with FASTBOOT UPDATE xxxx.zip maybe with correct prepere zip but my knowledge is itoo small
I have EDL cable, but i cant put my phone in Emergency mode / or do somethnig to my PC detected as Qualcomm 9002 mode ( maybe if battery will be pull out but i dont wona do that or TEST POINT but for the moment on internet is no info about this possiblility )
All is very sed, my question is why i cant flash this phone with orginal firmware using fastboot that is crazy i uderstand there is no possibility flash system from other phone by fastboot etc. but with orginal should be able but is not

Have you tried the simple thing using button when power they call master reset using buttons : (sounds silly) but worth trying
Turn off the device.
Press and hold the Power and Volume down buttons.
When the LG logo appears and quickly release the Power button only and press Power button again but keep pressing the Volume down button until you see the picture below

I assumed that you don't see any com port (Only Android Bootloader Interface)
in your device manager right?
@ car2carl

There was a time when I was in fastboot mode using fastboot reboot-edl was working and switch to download mode (using the patch fastboot from link below)
https://forum.xda-developers.com/redmi-note-3/how-to/guide-reboot-to-edl-mode-fastboot-test-t3398718
But I couldn't repeat it again.
I have XQCN/QCN backup for my phone and I save it , just in case I need it if my flash gone bad, but when I need to restore using qfil or qpst those programmer looking for COM port.
it is easy to get safe mode /diagnostic mode/download mode /fastboot mode when we don't have problem with bootlooping like yours., what was happen to you, holding me from flashing for experiment.

Hi,
I have a lg G5 H850 stuck into "fastboot for bootloader unlock" mode and recovery or download mode are not working, I tried to recover it by unlocking the bootloader but the OEM unlock option is disabled so I cannot flash anything.(device locked error error message)
I saw a YouTube video yout ube.com/watch?v=ImJ1xXXzV6s with my exact issue but he is not responding to my messages.
Is there any option to unbrick this device?
Thanks a lot in advance to all!

Hi guys,
it's been more than two hours that I seek the solution to this same problem with next to me the LG G5 bootllop.
All other solutions give nothing:
- unlook via fastboot makes a mistake because the debugging option is not enabled
- the download mode does not remain more than 15 seconds
Guys, have you found a way out of this problem?

You can try getting the .kdz for your phone (e.g. off lg-firmwares.com), use the WindowsLGFirmwareExtract tool to extract the .dz out of the .kdz, then use the tool to extract the laf_6.bin out of the .dz. You can then flash this in fastboot mode using a command like
Code:
fastboot flash laf laf_6.bin
Make sure to use the same .kdz as your running firmware.
I had the same problem with Download Mode as you (restarted after 15 seconds). I extracted laf_6.bin from the H85030e KDZ firmware (whose boot stack was in use), and flashed its LAF (i.e. Download Mode) volume over the laf partition. After this Download Mode stopped restarting after 15 seconds, and I was able to use LGUP (and you would be able to use UPPERCUT) to flash the full KDZ.
(I proceeded to start the phone in bootloader/fastboot mode and flash TWRP recovery as well, with my unlocked bootloader.)

interesting. I am in Bootloop from two weeks. Tried to much time lineage 17.1 and then leave the phone so many hours in order to boot in lineage that at some point it won't enter system anymore.
So I passed to LGUP that works only with UPPERCUT and only with UPGRADE functions even if I installed all the drivers.
Maybe I need a "megalock.dll" file?
But the way one week trying to boot in system after flashing KDZ files with UPPERCUT and after many and many bootloop I finally enter the system with H85020a_00_OPEN_EU_OP_1030.kdz
But after one reboot it returns the problem.
I am desperate.
Have you got a phone name to buy that is unbrickable?

Mi A3 weirdly stuck in fastboot mode, please someone help
I recently opened my mi A3's bootloader and then flashed twrp image as it was error or something, my phones got stuck on fastboot mode and after that I have to flash stock rom v11.0.11.0 through mi flash tool and I successfully worked but then I installed magisk and flashed boot image to obtain boot image and that too successful worked but guess what real problem starts here, after the other day I restarted my device and android one logo showed up and then it got stuck on fastboot mode, then I have to again flash the same rom and again patched boot image file to get my phone back working and it went well for 2-3 days but suddenly, yesterday magisk notified that "DTFO is patched, tap to reboot" and I ignored and after that after few hours my phone automatically got restart and stuck on fastboot again and now when I try to flash the same rom again, it takes more than 3500s in mi flash tool and still not showing success, currently stuck on fastboot, no flash tool is working, can someone help please??
