[LG Optimus 3D] jocazmaj:
Damn man, you should really read more...

It asks for password because it's the legit version, so you must crack it with the crack file...

If you don't succeed wit LG Flashtool you should try mobile support tool, it's easier.........

Download the files and follow the guide.

or

In short you will do this:

1. Flash .kdz firmware update[offcourse unofficial ICS v28b or v30a]

2. Flash wkparks 1.25a bootloaders

3. Flash custom recovery[TWRP or CWM]

4. Root the phone in recovery

It's quite simple so if you don't succeed I can't help you because it can't get easier than that so follow the guide...And read it at least twice before you start the process.

Here is the V30A firmware for P920[you can find the link for V30B AT&T for P925 in the forum] and NO it does not contain any viruses...I flashed it on my phone two times already.
