Re: LG Xboom PK5 demo mode..probably

Hi, I have a couple of LG XBoom PN7 speakers, one of which was stuck in what I now know was demo mode, only works when plugged in, power button doesnt work, stuck at max volume and no BT. After scratching my head for a while I chanced upon the firmware file for the PK5 from here.
I took the demo speaker apart and found the firmware chip, unfortunately it was only a 1Mb chip, so the PK5 firmware could not be flashed to it. I took the chip off of the board and put it in my CH341A programmer and read the hex from it. I really didn't want...
