Sonicwall TZ400 redeploy again?

[nospamever]

Have a decommissioned Sonicwall TZ400 from work and been sitting in my cupboard. I am familiar with Sophos and have pfsense installed but TZ400 looks like a different animal. Can't find anywhere whether TZ400 can be installed with any linux firewall. Have you come across if this is possible?

Seems like this box can't run anything else than stock OS. Signed bootloader and MIPS64 processor.
