Let's say you just hit 90 and want to do LFR but don't have the ilvl required to get in. What you can do is have TWO friends who can enter LFR, queue for the LFR you want to join then queue for a Heroic dungeon. Once they are in both queues at the same time invite you to group and you will join the queue in progress.
You can also use this to bypass the gating system that forces you to complete the lower tier LFR before being able to queue for the next. Like having to clear Heart of Fear before being able to queue for Terrace.
floWWW originally posted something similar here:

Except that just queuing for LFR and having them invite you doesn't work anymore. You need to queue for LFR and a Heroic dungeon at the same time.
This apparently also ignores level requirements as well. I tried this with a level 1 and was able to successfully join the queue and have the queue pop but received the error "This character is too low level" when trying to join the raid.
If this is a repost, my apologies. I searched and floWWW's post was all I could find.
