This is a syscon firmware update, not a CP update.

CP updates are usually called reftool_cp_xxx.bin (replace xxx by version) you can find these in official sdks.
Syscon firmware updates use other keys and another algorithm.

Thanks,

{{keyboard|content=<syntaxhighlight lang="bash">openssl enc -aes-256-cbc -d -K E8ED2B817207B70C5DF9090507AF2A8982967620D692B92A59231638402DF13F -iv FB306DA62E530EB13FB9D0EF8615060A -in reftool_cp_133.bin -out reftool_cp_133.tar.gz</syntaxhighlight>}}

works. (I should learn reading ;))

== Extra Information ==
I would like to add that it's much easier to interact with the System Controller from the Communication Processor shell considering that Syscon on Reference tool does not require any authentication or encryption of the packets sent to it and you do get real time replies, Syscon on those units also allow many more commands than on consumer systems (even after using AUTH1/AUTH2), this can be rather useful should you want syscon to jump to your code (Syscon is powered by an ARM7TDMI (ARMv4) CPU) by performing a packet overflow.

* Because Syscon's firmware is fully overwritten on a DECR-1000, it is trivial to downgrade its firmware if you are connected to the CP's Shell. (There is actually a script on the CP rom that does just this, all you have to do is to comment the version check) (patched update_syscon.pl: [[http://pastebin.com/ZMxvTxwL]])

The Communication Processor can also talk to the southbridge.
