Edit: correct link now.

I Extracted kdz file correctly, then using instruction from your link I tried to flash this phone, but this is showing under READY command:

Result: it's bricked and other people in some Brazilian forums have done the same mistake. I'm trying to help them.

If turned on normally it gets stuck in LG's logo screen. Hard factory reset using buttons or USB cable method doesn't solve the issue.
The user says he tried many ROMs (probably also L7 I ICS ROMs :x) and after installed some ROMs make white stripes appear in the screen and others will make the LG logo screen to blink.

If turned on with the right buttons to enter emergency I think it does normally.

LG Mobile Support Tool isn't able to recover it. It gets stuck in % / says unknown error.
Tried KDZ with PhoneMode Diag, Emergency and CS_Emergency, nothing will recover it. Attached is a screen of a failed try of putting the correct stock L7 II P715 firmware on it.

My idea: maybe we can recover it by flashing a custom recovery (via adb or something else that works in emergency or download mode) then he could flash anything in his phone including the correct kernel and ROM and everything should be fixed, but since unlocking the bootloader is a requirement (please correct me if I'm wrong) and it seems the only method of doing so requires a phone working normally it seems there's no solution.

The technicians from repair centers are noobs, they were unable to recover it (I think they don't even have a BOX for this device model) and blame things like the motherboard or screen.

Any help would be appreciated.

You can get the official kdz using this method http://forum.xda-developers.com/show...0#post22225030 . and probably flash using KDZ updater.

So, for those, who may encounter this error. I solved it by bringing my phone to Service Center. As a result it was very hard to bring it back. For my luck, master was good enough not to give up and get job done . He worked on my phone for more than a week, everyday, tried 2 different programmators. He flash 34% from original stock rom and that allowed him to get into recovery. After that he finished flashing.

I watched movie of repair process, that he showed me. It was crazy) phone was completly dissasembled and programmer was connected via very thin cables)

Did you flash your ROM via CWM (zip) or via KDZ? If it is the latter, it means that CWM is probably gone. Are you able to boot to recovery now?

I Flashed it using zip and after restart it bricked. Then I used every single method find in XDA forums like KDZ Updater, offline updater,LG Flash Tool etc.
I tried various roms too i.e. Official, custom, rooted but none worked. Only rom worked was P700 V20D, which flashes upto 99% . I am also unable to use ABD as it not shows in device list.

OK, did you try this? Although it's for P710, it should still install the recovery for you, which should be the same. Then you can go on and install any custom ROM via recovery.
