I suggest you download the thing one more time
the 1,07 from nec should be downloaded from their site at this adr. :
1,07 firmware for nec 1300a
wheile if your using henries version of it, IÂ´d regamende you to do so, its more media type friendly.
it can be found here:
henries version of the firmware
anyways good look with it....
oh and in both cases, all I had to do was double click the .exe file and press the "flash button", then wait for it to get flashed and then just let it power off. ( which I recamende you do after the flash ). then boot up and marvle at the genious behinde the technologies.
