I Have the V09a and I would like to flash V10b. The original upgrade tools does not work.
Is the any other way to do that?
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
