Downgrading to 4.3.3 using iFaith shsh blobs

[jamran]

As title says guys, I was on 4.3.3 and suffered reception issues on my jailbroken phone. I saved recovered the shsh blobs using iFaith for 4.3.3. When I went to apple, the genius updated the firmware to 4.3.5.

Know is it possible for me to downgrade to 4.3.3 using the 4.3.3 shsh blobs that I've saved on my pc or do they have to be saved on cydias servers?

Please can someone advise.

I attempted to make a custom ipsw using iFaith but after installing my phone remains on dfu mode and I can't get it out!!

Any help will be much appreciated.

Jus to update u if anyone can help, I managed to start up the phone using redsnow! It's started up I even made a call but then suddenly it went back into dfu mode again?!!!

I don't know wtf is wrong

All you have to do is hook up to iFaith dfu mode then click shift/restore then choose the custom ipsw.
