128w ago - Recently we
reported on a 3.50 Firmware JailBroken PS3 x3Max video, and today PS3 developer
xorloser has commented on the hack, as well as explaining why obtaining the hmac key for PlayStation 3 PUP files will not lead to PS3 Custom Firmware.
To quote from his blog, linked above:
"the hmac key for PUPs doesnt magically allow custom firmware. this is because all of the files that make up the PUP are signed anyway, so you cannot make custom versions of any of those files because you cannot sign them.
as for x3max supposedly working on v3.50, i call fake."

they should just release it to all to benefit the scene. But no. 
No
Are you Depressed?...

Earlier today it was reported that our group discovered the masterkey – I can confirm this. The video released last week was done prematurely and out of excitement. Many of you are pushing for us release our 3.5 solution understandably so. I completely understand the logic that once released it’ll be cloned and truthfully that’s inevitable.
At the same time we must do our best to prevent, or at least delay that from happening. Using the PSdowngrade as the most recent example, in just a couple of weeks we’ve seen the DigiKey team port the downgrade to their multiple brands. Given our dedication to the X3Max it's imperative our solution is secured to the best of out ability before being publicly released.
