[Q] Help! Fastboot seems broken - G3 Q&A, Help & Troubleshooting

Hey guys,
So i was trying to upgrade to lollipop by flashing laf, boot, and system from twrp, and now i'm stuck in fastboot.
The problem is, fastboot doesn't seem to do anything. When i send a command, it shows on the LG Screen (fastboot: processing commands) but it doesn't actually do anything.
If i try to boot into the OS it shows Security Error, recovery is gone, all i have is fastboot mode.
Any help would be appreciated.

Hi dear frends.
Its sad to know that all you guys cant go to download mode or facing security error or stuck in lg logo or in fastboot mode
And some guys stuck qhsuab bulk 9008

If you are unable to get into download mode then you need to force your g3 into qhsusb bulk mode by shorting the test point.

Asus Zenfone 2 Bricked , Please somebody help

Hi all members,
I dont know anything much about develpoment, I have ZE551ML 32gb version. I rooted my phone and it was working fine until i installed layers manager from playstore and applied new layers and instantly after restarting the phone was struck on bootloop .. So after searching a bit i managed to open the phone in fastboot mode .
after then i did a factory reset and restarted the phone but the problem of bootloop was still there .. so after searching more i decided to install a custom rom, for that i first used adb tools to flash a twrp recovery in fastboot mode and when i try to enter in recovery mode the phone restarts and enters the fastboot screen itself not on recovery screen. So for me there is not way to enter in recovery mode . So someone please help me and repair my phone i will be very grateful.
Yea you can only install layers for roms that support them. stock doesn't support it. is your bootloader unlocked? if not first do then that try flashing a recovery again.

these devices have locked bootloaders. how did u install twrp?
best bet would to be to find what ever firmware device was on and reflash it with lg up or flash tool if u still have download mode.
Thanks for your reply.
I really don't know what i did to install twrp.
I try to use flash tool but doesn't detect my phone.

With flash tool goto device manager on pc.
click ports and com get into settings on it and change com port to 41
and have device in download mode powered off volume up + insert usb cord from pc
@imider I have the same problem trying to recover from a hardbrick on H815. Tell me what happens if you pull battery, plug bag, hold VOL DOWN and insert USB. Do you get fastboot?
EDIT: You might be able to flash it in FlashTool (I said no before) because I see you have Official Status not MODIFIED.
Thanks for your reply guys.
I manage to flash it with LGUP with a TOT that I downloaded.
Thanks.

Congrat @imider ,
maybe you can share what you did to fix your G4
Hello,
First I wanted to flash a clean rom on LG G4 H810 and I don't know what I did but the flash doesn't work and my phone has a black screen even the logo is not displayed.
When I connect my phone to my PC (windows 10) it's detected as "Qualcomm HS-USB QDLoader 9008".
Now this is the step that I follow to repair my phone :
1) I follow this tuto : https://forum.xda-developers.com/g4/help/lg-g4-bricked-qualcomm-hs-usb-qdloader-t3609999
2) After that I can enter download mode
3) I flashed a tot with LGUP
I hope it will help.
