Updated to IOS5.01 today, and sim is not activating also can't get into DFU mode.

Hi all i made a stupid mistake i updated from 4.3.3 (Or Something) to 5.0.1 today but my sim is not activating but also i can not get into DFU mode because my Sleep/Power button is broke, I was wondering is there anyway i can downgrade again (Note i do have the 4.1 shsh as i used to jail brake my phone)

Is there any way i can downgrade or get into DFU mode so i can jail brake my phone also i can live without the Power button.

I can't really take my phone to apple to be repaired as i have not got the time or money.

any help would be great.


Thanks

Search through the forums, there's a way to force DFU mode by modifying the LLB portion of the .IPSW, recompressing, and attempting to restore it to the phone. This forces the phone into DFU. If you have SHSH on file for 4.1, you can use it and TinyUmbrella to downgrade. Search the forums for this as well, both questions are asked very often and have been answered many times.
