Its is bricked but luckily you can repair your Brock by using srk tools. There are plenty of videos of how to unbrick your phone using srk tools

[Q] [L7][P700][Bricked] Hard bricked Optimus L7 P700

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

Help Me Bricked LG G2

I tried to download via lg tools and flash something and failed.
when you restart the phone gave me the black screen.
I run ubuntu from the procedure
http://forum.xda-developers.com/showthread.php?t=2582142
after trying this procedure, the phone remains fixed on the lg logo.
How can I fix ??? I pray you are in a panic ...
the computer does not recognize the phone more
:crying::crying::crying::crying::crying:
What phone model do you have? Sounds like you might have to boot into download mode and use the LG tool to go back to stock completely.

I have a d802
the phone is stuck on the lg logo.
As per the procedure would have to start the recovery but will not start.
Not part of the download mode.
I can get into factory reset but the pc does not recognize.
It seems to me a serious case. The guarantee how it behaves in these cases?
Dont you have recovery to flash new rom via ADB?
Try with ubuntu once again it will work out
ubuntu does not recognize the phone more.
The recovery is the original one.
Make sure the ports on the pc are set to 41. Do you have the drivers in the pc as well?

Verizon LG G2 downloade mode broken

I've been looking around the the last few hours but I can't find a fix to my problem. I ended up bricking my LG G2 today after flashing a paranoid rom. I had selected everything to get wiped including internal storage (which was a stupid mistake) and now I have no roms on my internal storage. Plus I'm stuck at the LG logo screen which isn't blinking. And to top it off download mode boots straight to fastboot and I can't get the computer to recognizes the device when its under fastboot but it does when its stuck on the LG logo. I've tried the drivers already and they don't do anything under device manager for it to notice the device plugged in. Anybody got any ideas?
