Downgrading or Activating iPhone 4

[Xegano]

Hello guys,

When I recovered my iPhone like 3 days ago I couldnt activate my iPhone anymore
It keeps searching and then it says No Service although I did activate and install UltraSn0w
So I decided to downgrade back to 4.3.3 because it worked with that version but that since I didnt save my SHH blobs I couldnt It keeps giving error 20 or 3964 if I dont use TU, I did manage to get it back to 4.3.5 since I somehow that the blobs for that but also on that one it doesnt work :/
I tried everything been working so much on it but unfortunately nothing works @.@
Could anyone help me with this?

Let me decide for you .
Create a custom firmware of 5.0 from snowbreeze 2.8b11
Put your iphone into pwned dfu mode.
Don't use tiny umbrella, use it to set your hosts file back to apple server by unchecking set hosts file to cydia.
Now restore with latest iTunes to custom fw of 5.0
Look at your basaband, if it is not 1.59.00 which I think you won't have it , then go get a gevey sim to unlock it

Btw, this is a tethered jailbreak meaning tether boot if you see a White icon or frozen apple logo.

Yea I already tried that and activated with sn0wbreeze but I still had no service
About the Gevey sim card is it 100% working, and where is the best place I could get it from? Also I bought from dealextreme a universal Activation sim card (waiting for delivery) wouldt this work too?

What was the first stock fimware version you restored.
Get it from applenberry : gevey ultra pro should work as long as your preserve your 4.xx Baseband.

[Xegano]

At applenberry it says it doesnt work with my bb (4.11.08) @.@

[iYeow]

That is correct ,it will only work if you preserve your iOS 4.xx baseband.

[Xegano]

How do I do that @.@
With snowbreeze?
So if I use the preserve baseband thing I can downgrade my baseband?
Or is that just impossible?

[iYeow]

You create a custom firmware of 5.0.1 , put iphone into owned dfu , run iTunes > shift + restore to cfw 5.0.1.
Your bb is preserved this way. You can use snow breeze

[Xegano]

Oh then I suppose I am too late now since I already have bb 4.11. I cant downgrade that right? I guess thats the problem. I noticed I do have a gevey pro lol but yea it doesnt work with bb 4.11 I guess So I am probably screwed till there is one which supports 4.11 :/
