I have downloaded
allbest-a720-100c-31.zip and the extrcted it to my SD card. The two files
DISKBOOT.BIN and
PS.FIR are on the card in the root directory. I put the card into the 720IS (1.00c) and then switch on in play mode. Then I press the MENU button. There is no sign of
FIRM UPDATE. What am I doing wrong?
