Did you know your tool does not give a proper pending dump?, if you compare the two apps one dump from FirmwareDumper and yours BiggestDump you will notice in biggestdump placehld folder which contains the pending updates, it's not correct! it comes out as some random size.You can try mine instead. Just dumps to "sdmc:/Update"
