Not sure if there is a thread on this or not, so here goes. According to the official page, the firmware has been rolled back to 11.3. I'm guessing this is due to that massive banwave, which affected non-hacked units as well as hacked units. I, personally, am still on 11.2, but, if anyone is running OFW 11.4, please try and see if you can legitimately downgrade back to 11.3, and report back here. Here is the page:

It could be out of date, but I cannot know for sure.
