if device boot direct in fastboot mode means ur already unlocked

really would be nice.. is there a way to check the bootloader if it's already unlocked or still locked?

Hi Sicness, two ways:
1) put your L9 in S/W mode, if it's unlocked there will be a little test saying it.
2) with the hidden menu 3845#*760#
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Cheers. Good luck.

Hi Sicness, you're welcome. At the moment I'm on stock P76020p-EUR-XX. I'm thinking about Slimkk, but I don't know, there are a lot of good roms out there...
Cheers. Good luck

Hi Sicness, you need a PC and an USB cable:
you have to turn off the phone and remove the battery,
put the battery in again, hold volume up and plug in the USB cable, you'll see S/W Upgrade. (If you see the LG logo repeat again) .
Cheers. Good luck.
Edit: for the second method you must enter the code in your phone as if you were doing a call.
