Please help me restore my iPhone 4s

[lordvoldemort8]

Hello experts,
Let me give you all the details about what I have and what I want to do

What do I have?

iPhone 4s 32 GB
Factory unlocked.
iOS-5.1.1
Jailbroken

Using iOS 5.1.1 since when?
Since june 2012

What is the issue?
My phone is showing 12GB of 'other' space utilized when connected to iTunes.

What I want to do?
I want to restore my iPhone as a new phone.

Then what is the problem?

I want to restore my phone to 5.1.1 itself and not upgrade to iOS 6.0
But I read that apple stopped sigining 5.1.1.So,if I restore via iTunes,I will have to upgrade to 6.0 and will be no longer able to jailbreak my iPhone.

Managed to get my SHSH blobs via tiny umbrella thru cydia's servers..So having them in my pc.

i first thought of doing 'Erase all content and Settings' but It seems jailbroken iPhone goes into a bootloop if done so.

My question is
How can I delete all my content or setup my iPhone 4s as new phone without upgrading it?

Please guide me with your expert opinions.

Have a nice day!

Ok guys,Managed to get my SHSH blobs via tiny umbrella..So having them in my pc.
