Do you have the correct usb drivers installed on your computer?
I think so. fastboot mode detected fine before but when i flashed laf file using lg g2 unbrick g0dsend313 file then this happened to my cell phone. I have attached the pic of download mode. Is it a normal download mode??

Guys finally i have again access to fastboot mode. And i have tried many laf files but nothing is happening. Just stuck into fastboot mode. Kindly can someone help me on this i have 32GB modal.
My suggestion since you just bought it is return it tell them you received the phone and it just refused to do anything. The store should replace it.

Hey guys,
Yesterday I tried unlocking my phone using the tools provided on this forum, but somehow my device got hard bricked.
It is just laying there with a black screen. It won't turn on, won't boot into recovery or emergency mode. Nothing.
But when I connected it to my PC (running Windows 7), I did hear the sound that it recognised it as a device, it just couldn't find any drivers for it, so I wen't to look into that.
Landed on the debricking method using QPTS on the CyanogenMod forums and I managed to find drivers for Windows 7, so no need for an XP computer!
There were some other Optimus L-series brickers who gave up on the process, but I have still some hope left.
Did all the work that had to be done, decompiled V20D KDZ for our device, converted the first 512 bytes of the partition.bin to .mbn, installed QPTS, and so forth.
Hooked up my phone to the pc holding the volume-down button, and QPTS actually recognised it as a phone in downloading mode!
Then that's where I got stuck. Using the HEX files from this thread, I get the following error:
Code:
Status: Software Download Aborted
Errors: Could not determine the HEX file's scrambling method. The file is invalid.
Do any of you have a clue on how get things working again?
The QPTS tool only lists MSM7x30 (eMMC) as ARMPRG to use for the phone in dowload mode, not the MSM7x27a we are using. Might this be part of the problem?
Any help is highly appreciated!
Can you go to emergency or download mode?
Battery taken out, hold the vol up + connect to usb, connected to the pc. Then you will see in a green screen with emergency mode.
Once your done that, be sure you installed the LG drivers, flashed through kdz.
You can use homero's v20 stock, it's already had cwm and unlock bootloader and v20 baseband.

Nope, can't get into emergency mode, screen stays black, no matter what. So yeah, just flashing a new KDZ isn't an option. :crying:

Does the kdz flasher recognized the phone? If it's turn on and connected to the PC.

You should try launching emergency mode some more. Install lg drivers. Take out battery, hold Vol up button and plug in usb. Make sure port works.
Thanks for the replies, guys!

I can't turn the device on. When I connect it to the PC, Windows sees the phone as an 'Unknown Device', even with the latest LG drivers installed.
And by KDZ flasher you mean the BC2App, right?

Tried it a dozen times, with different combinations too. Only thing that happens is the sound windows makes when a device is plugged in.
Any chance a method like this would work? If the .img.zx file would be edited for our device ofcourse.
Hey all,
I couldn't get any further debricking my phone myself, so I just brought it to a repair shop. I'm hoping they can do something using JTAG or something.
Regardless of getting my phone working again (hopefully), I would still love to see if we can find a way to debrick hard bricked devices. If we can find a solution, I'll volunteer for writing a tutorial

Can someone please post a link to download qhsusb dload drivers and tell how to install theme please.
Is your phone working? Because if you're plugging your phone to the computer and getting this error and your device is not working... it means your eMMC is fried.

Did you solve your issue? I am in your same situation
Hello,
I've looked for solutions everywhere and have spent the last days trying to fix my phone but i can't find a solution. Here is my problem:
I bought a second hand phone, it was working fine however it had been rooted and was running on Cyanogen.
I therefore tried to revert this to a stock EU ROM I downloaded. I was able to do this through the LGMobile Support Tool.
However when the process completed, my phone was stuck in a reboot loop on the LG logo. So I went back to the LGMobile Support Tool and selected 'Upgrade Recovery'.
After completing this, my phone was still stuck on the loop, but now I'm unable to access download mode, or recovery mode.
My phone is detected in device manager as LGE AndroidNet USB Serial Port (COM4) and LGE AndroidNet USB Modem when plugged in.
I don't know what to do? Please help.
This is now resolved thanks to bender_007

Try wiping through stock recovery mode (hold volume down and power, wait for lg logo then hold volume up and volume down-without power button)

:good:
Hi.
I just got myself a G2(crazy right) and I bricked it in 8 hours.
I tried to fix it using the famous thread from XDA, and I did it until it started to boot loop, and gave me no recovery mode when I tried.
I also tried connecting it back to the pc to get TWRP rebooted and stuff, but the pc did not recognise the phone.. It didn't even read it.
So i'm stuck with a boot looped phone with a download mode that does not connect to pc, and no recovery mode.
Please help. I am so tired of this phone- all I wanted to do was dual boot it.
Thanks in advance.
My Lg H990 ds stuck on bootloop, the only mode that i can get to is fast boot mode .i know only fastboot mode is last hope for my phone alive.
I wants unlock bootloader file for partition install @ fastboot mode .....
Plz help me
