Hello all..   do you remember me?  I was really lucky and I solved 3 blocks within a few weeks time.   The third one was (i believe? ) the pools first ever orphan...  that was a bad day.  I'm sure Con remembers.  My screen name was wmtomlinso.

So, have you guys noticed that Bitmain has posted some new firmware for a few miners.   Not knowing any better, I installed this new firmware on my L3+.  I saw no improvements so I proceeded to put my 3rd party firmware (Blissz) back and now the miner will not accept it.  Evidently, bitmain added a security enhancement to prevent us from loading any firmware except official, signed firmware from bitmain.

Have you guys observed this?  and is there a workaround?  And forgive me for posting off topic.   but I know that you guys will know about it and point me in the right direction.
