Like the title says.

I am looking to downgrade from 4.3.x to 4.1
The catch is, i want the 2.10 BB i have the 4.10.01 atm.
I have 4.1 SHSH on hand.

But so far everything i did, it kept on preserving the 4.10.01

I need it to test something out ... activation wise, (I think iMessage and Facetime rely on BB blocking some of use to send the SMS needed to activate)

Let me know or point me in the correct direction, thanks
