Root Hboot 2.15

[Altaone]

I think that when I flashed Maximus it changed my Hboot to 2.16 - I dont know for sure that maximus changed it, but my RUU for my phone will not work any more.

I would like to go to Hboot 2.15 because it seems there is more active / users with CM 11 on hboot 2.15 - can someone point me in the right direction - are there things I am not aware of - should I stay on this hboot

Phone is s-off stock CID but CID is easily changed, I just liked the idea of having an RUU that would return the phone to stock.

I have not done any of this myself, but here is some info.
First, you are S-OFF (GOOD). I asked this before and if you are S-OFF apparently all you have to do is this:

"2.16 to downgrade easy take a ruu pull out firmware zip from its rom zip flash firmware"

So theoretically, simply pull out firmware.zip from an RUU that has HBOOT 2.15.
But there is this comprehensive reply:

Good luck!
