[Q] [SOLVED] L5II (LGE455F) bricked after update - LG Optimus L3 II, L5 II, L7 II, L9 II

Hello!
Well, direct to point: I was trying to debrand and update my phone. So, reading some tutorials, I find two ways to do this: using KDZ Updater and using a KDZ Offline Update with a script. In both of them was necessary to download a KDZ file from a site. I downloaded it (in my case, V10K_00.KDZ).
I just start the easiest tutorial, KDZ Updater. I installed the latest LG drivers, disable modem, configure the program, etc... but... I always give me an error saying "phone not found", doesn't matter the phone is download mode, recovery or normal mode.
So, I go to second tutorial... I edit the hosts files and started it. This tutorial works with phone in download mode. The phone changed the "download mode" line to "downloading", and at 94% the update process reseted the phone, and at this point my windows find another device, but the drivers wasn't installed. The update process then don't find the phone anymore, asking me to unplug the phone and plug it again. I do this, but it keep asking.
The phone don't turn on anymore. No vibrating at press power, no LG logo, no bootloop. Just nothing. BUT... If I plug it at computer, it still detected by windows! And now, I have TWO situations when I plug it (with or without battery):
1. If I just plug, windows find a LGE AndroidNet USB Modem and a unknow device. About two seconds later, both are desconnected and the unknow device appears again, and only it. The modem don't appear anymore.
2. If I plug pressing volume + and - buttons, the two devices apeears, but one still not recognized.
Then, I unplug the phone and search for the second device driver, using this PID (Vid_0e8d&Pid_0003). Is a "6218 USB Modem Driver", appearing under "ports" on device manager, sometimes with COM5, sometimes with COM4 and so on. I found driver only for WinXP, but it installed correctly.
So, I started the process again with the two situations. First with KDZ Updater, with same problem. With second method, but it give me erros about phone connection, or terminate with an error about general failure.
I tried to restore the phone to original ROM using another tutorial here, using LG Mobile Tools. I uninstalled and undo ALL stuff, clean registry and temp files (with cCleaner), installed the latest drivers again and download the latest version from LG. It detect my phone, but it always give an error saying the battery is not charged enought (in both situations). But the battery is OK, I charged it to 100%!
Now, I don't know what to do. Looking for more tutoriais, I find the LG Flash Tool 1.2, but it don't detect my phone or says "FAIL" on COM port of 6218 USB.
There another way to recover my phone? I have tried to update first in my notebook with Win7 SP1. Later (after the disaster) I tried on WinXP SP3 too. No luck.
Sorry for long post... but is a lot of detais...

Well...
I formatted another PC for tests. Used WinXP SP3, with all updates... But no sucess. Here go log from OfflineInstaller_Fix, if this helps:

Thanks. I already tried this, but no sucess. Tried with another program, LG Flash Tools 1.2, too. Nothing.
Now, I'm thinking about the KDZ I'm using is the problem. I'll try everithing again, with another KDZ, version V10A (the same from my operator). I post the results later.

Well, phone turns on again. But ONLY with same KDZ version from operator (V10A_04.KDZ).
I'll try with an older unbranded version (V10E_00.KDZ), and post results here.
EDIT: can't download. The link with counter on upperside don't appears. Any problem with the site?

Hi there, i've got that problem.
A friend of mine asked me to fix his phone, it was stuck at booting screen after updating, I don't know how he tried to update, but I solved this one problem, then I was able to root the phone, but after that, it says "emergency calls only".

I don't have this phone anymore.
You can try re-flash to get phone working again, and then try root with Kingo Root.
