3G | 4.2.1 | 06.15.00 | No SIM card installed?
Hi there, I have a 8GB iPhone 3G, version 4.2.1 with baseband 06.15.00. Jailbroken.
I recently bought this iPhone from a friend, worked fine with my Fido Sim at friends house. Once I got to my house it started getting the no sim/searching error. So as a noobie mistake, I tried the basic hard resets, toggles, etc. I THEN idiotically tried to restore it through iTunes (knowing it was jailbroken) thinking it might solve the problem. Then I had the "Getting iPhone out of restore mode iTunes screen" and got my Phone back through redSn0w.
Now I have a bigger problem of my Phone not recognizing the sim card AT ALL. It constantly says "No SIM card installed" every time I start it up.
So am I dealing with the same problems of people who get "no service" and that my phone is locked? Do I have to downgrade my baseband in order to properly install ultrasn0w?
What I have tried
- Hard Resets
- Using different sim cards (rogers, fido)
- Installing ultrasn0w through cydia
Thank you for any suggestions.
