iOS6 Beta 4 bricked my device

Hi all,

I postet this in the iOS6 Bug post where someone suggested to open a new topic for this because I could reach maybe the one who knows a solution.

So here is the message:

Hi I got a huge bug..

I downloaded the beta 4 from the website and did a restore with the new ipsw.

When its installed and wants to setup I enter my Pin code. It says success and connects to 3G Network. No provider is shown next to the bars. Normally Telekom.de was shown.

Now if I try to activate the phone via Mobile Network or Wifi it tells me that the sim card is not useable with the device and I need to contact my provider to get a new one.

I tried many different cards in my company but with no success. I can´t activate it..! I couldn´t even manage to downgrade using the redsnow tool.

What I tried so far:
Tried to restore with redSnow to 5.1.1.
Tried to restore to 5.1.1 utilizing DFU mode.
Tried to restore to 5.1.1 utilizing Restore mode.

all with no success.

I also opened a ticket at https://bugreport.apple.com

Does anyone have another suggestion for me?

Thank you very much!

 

Hi pugnut,

The sim worked until today after the upgrade. I tried also the ones from my collegues. Every sim showed the same behavior. DFU is what I´ve already tried.. Restore while the phones screen is still black.. No success. As if the version is still iOS6 beta 4 and yes I chose the correct file for restore

 

I finally found the solution!

I asked a collegue which is on another carrier. In this case it was vodafone. I´m on telekom. I put his card in waited until it got signal then I switched back to my card and after a few minutes the carrier logo came up.

Than I saw that the revert to the 5.1.1 succeeded because the "old" iOS version is installed.

Phew I´m happy now and thank you everybody!
