Why would you want to update from FW5.3.2 to 5.4.0 anyway?. Everything good going for this exploit is being run on 5.3.2 also with the spoofer you have the best of both worlds.well if anything it will at least bring 5.4 compatibility which is a good thing, shame everyone applied that spoof which will mean updating to 5.4 from 5.3.2 will be a challenge......but for the most part it doesn't really matter unless you really really wanted that MM manual
