you need the lg pc suite to update with. get it here

install it and connect your mobile to the pc using the usb cable.
remember to connect the usb cable between mobile and pc BEFORE you turn on the mobile.
if you do not do it correctly, the S/W upgrade menu will not appear, and update might fail (which i believe you seen now?)
(hold VOL- pressed, when you turn on the mobile, and S/W upgrade will appear, otherwise try again)

from here, the pc suite will guide you through the upgrade. i might be missing that you need to select mobile upgrade from the menu, but that is just a matter of selecting it

When I plug the usb cable on my phone it automatically turnes on the prone. Any other way?

you have to hold down the VOL- when you that trick, and fast. there is just this way.

Is it still works? I activate S/W upgrade but LG PC Suite dont do nothing and "Device"=>"Device software upgrade" still inactive.
My ROM is v10a, should it work?

I suggest you to follow this guide http://forum.xda-developers.com/show....php?t=1264289
The only two different things are that you have to download and select the proper kdz for ours p880 and also insert the battery between fourth and fifth step ( when you reached the s/w upgrade mode ), otherwise the flash won't finish ( at least, for me it was so ).

PS: obviously in step 4 you have to keep pressed "vol-" and, at the same time, plug in the usb cable.

i can confirm when you connect the USB cable you only need to keep VOL- kept down and do it within 2-3 seconds or it will not boot up.

but power button is not needed for f/w upgrade mode.

yeah, I did not remember exactly if i pressed the power button or not

Is that all? Download LG PC suite and then connect USB? I tried that and got the S/W upgrade please wait while upgrading... but its taking forever.

ps: this is my first time rooting/flashing a phone.

hi there

here the same try to update after root using the lg software and it takes hours ....

is it possible to update normal after rooting??
