Re: LG Xboom PK5 demo mode..probably

I also purchased 2 demo units of PK3 but haven't figured out a way to turn demo mode off.
PK3 has a different motherboard design inside. PK5 and PK7 have 64 bit SPI rom chip inside but PK3 don't....

Re: LG Xboom PK5 demo mode..probably

my dump from PK5 works fine with PK7 as well, you can reflash your firmware chip without any doubt.
