[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

[Q] l3 flashed incorrect baseband help

Hi guys, can anyone help me with this, I recently acquired a lg e400 and rooted it, was going to flash cyanogenmod for it but i messed up and flashed a different baseband for a different model phone first(i know it was stupid, now i have a semi-hard brick and the only mode i can get into is a black screen, computer sees the phone as lge androidnet usb, i enter this by holding the vol down and power as i plug into the computer. I've tried every other key combo but cannot get into any other mode....i've tried using the lg flash tool with no success, tried uptest with no result, tried the lg mobile support tool and it picks up my phone as the correct phone lge400r with a software version of v20e which used to be a v10b....how can i flash just the correct baseband?....i also tried kdz and when i try and flash the original kdz file it starts but fails with wparam:100 lparam:1002, i'm thinking maybe i have the incorrect firmware kdz....could anyone point me in the right direction with this?....it's driving me nuts

I think that you should use this site LINK. There you have all of the firmwares for L3, and you can choose baseband

yes, i tried that, but the only mode i can enter is download mode.....kdz updater fails, is there a way to flash in download mode?

1. Download THIS, your firmware as .kdz file and LG PC Suite
2. Install msxml.msi, and LG PC Suite
3. Run KDZ_FW_UPD (some antivirus software can recognize it as malicious software, but I have used it, and there is not any problem with this)
4. Select Type: 3GQCT, PhoneMode: DIAG or PhoneMode: Emergency (I don't know what is difference between them, so you have to test it)
5. In KDZ File you are choosing your previously downloaded firmware which is in .kdz format file
6. Boot to Download Mode (vol down + power) in the same moment you have to plug your LG to PC.
7. Wait for drivers installation, if nothing is installing go to the next step.
8. In KDZ_FW_UPD hit Launch Software Update and you have to wait until you see message "===FINISHED==="
That's all.

[Q] Bricked my LG G2 need help

Hello XDA-Community
Today i accidently briked my G2 (D802 KitKat 4.4.2). I was flashing it because i wanted to unroot it but during the process an error showed up and my phone was dead.
So i tried to fix it with this method http://forum.xda-developers.com/showthread.php?p=48765620#post48765620 but it didn't worked as planned.
Now i have an G2 which is stuck in a bootloop and i can't even reach the recovery or the download mode and i don't have any custom recovery installed.
Anyone who can help me with this get's an 10€/$ PSC. I can't give more because i dont have any money left (16 years old).
Big thanks to everyone who can help me with this
PS: Sorry for my bad english i'm not a native speaker

While you wait for an answer make sure your phone is kept charged.
Have you tried LG flashtool and your stock ROM?

make sure it's off, hold the VOLUME UP button while plugging it into your computer, and that should get it into download mode.
Next try using the TOT method (google it) and voila!

Yeah the problem is that i can't even reach the download mode and my computer doesn't recognize my phone it's just an qshub device. ;(

I had the same issue bricking my lg g2 and i was stuck with the logo and nothing more not even download mode,recovery etc...
The way i got it to stock was i installed the lg g2 drivers and from there on just flashed it with flashtools kdz and got it workking again i think this shoould help you out just plug your phone and install the drivers and use flashtools

Install this driver then report me back or cap screen device manager to me.I will help you for fee.
