This package has the boot 1.30 and the newest factory flash (080305_nFusion_Factory_U27)

Do not use any old boot file or older factory file. Use only this one!!!

edit rc,
never reload the bootloader over any working unit, it may cause alot of problems, and may lock the unit and loop the EPPROM. For new units look in nFusion menu - System Information and you will see if this bootloader is preloaded or not.
