I'm in the same case but the R&D soft say there is an error. Plus I can't acces the hard reset menu nor recovery...
I can't also see my device on recovery as I only see in the device manager : LGE Android Net USB Serial Port.
And this is like that when I try to boot or when I'm in download mode.. Any help would be great...
PS : I try to make a restore with the LG Mobile Support Tool (the true one) but will only get answer in 6hours (best connection ever!!)...
Edit1 : That worked! I get out of the download mode and let the software do is job and there is new! Now I have to put a pin /password but I don't know which one ^^' ... I've tried to go back in download mode or hard reset mode but it don't work..
Edit2 : I don't get how but I manage to get in download mode. After that I perform a restore to another kdz and now I'm using the factory reset which seems to take a lot of time..
