The only say you can downgrade is if you have saved signed SHSH blobs from before for that iOS version like seller1978 said.

You need to wait for you current firmware to be jailbreakable and you can use tools to help trick the device into thinking ios6 is signed.

But I don't want jailbreak

You have to first jailbreak the current firmware and then downgrade to ios6 which will erase your jailbreak and you will be left with stock ios6. Here is a link to odysseusOTA the tool used to achieve the downgrade. Keep in mind that you will need to be on a jailbreakable firmware. http://www.redmondpie.com/odysseusota-do...

Did you mean jailbreak first and then clean the jailbreak?

door

yes exactly. the jailbreak will be gone at the end.
