4.40 DEX

From PS3 Developer wiki

Do *NOT* install this on a converted machine
It will result in the machine not allowing you to finish installing the update or even a brick.

There is a check on eid0(!) in lv1ldr, that will trigger a panic (fun fact: it's impossible to generate the checked data yourself, so no Cex2Dex without ugly patches anymore). See also: X-I-5-Passphrase

You can only recover from this with a hardware flasher
