Upgrade SoundPoint IP 335

I have a bunch of old PolyCom Sound Point IP 335 that I inherited from past employees that have left, they NEVER upgraded or patched them. 


I am not familar to PolyCom phones how can I upgrade to the newer 4.0.x versions? 

SIP Software Version

BootROM Software Version


I have built a TFTP server and I upgraded SIP Software Version to, but when I try to get to a 4.0.x it states "Image incompatiable". I understand that this is most likely a BootRom issue but how can I fix this? Or can it even be upgraded? All the files are so complicated
