Ive recently bought a couple of iphone 3gs, purely just for the challenge, one had a smashed case, and screen, lcd backlight gone, soldered in a new coil to the board and put it in a new case with new speaker/mic ass and a few other little fixes and its perfect, been using it for a while (my first step into smart phone ownership, no worries.
The second phone was dead backlight only, this one was the lcd gone rather than the coil so i replaced that, then i did a restore from dfu mode on itunes which went smoothly in the end, i was getting a 29 error which turned out to be the wrong battery fitted which was stopping the restore to begin with. Now the phone is restored but when i try to register it it says no simcard is in the phone when it is, now with a bit of searching i find this happens when you restart a phone that has been jailbroken and there is so much bs on the net its hard to pick out fact from fiction, does anyoe know what can be done to end up with a working phone? obviously i cant actualy activate the phone to get into its menu, so this has to be done some other way.
The questions are do i have to jailbreak it with redsn0w or the like (would prefer not to) or is there some way i can restore the phone to its factory state (would have thought a restore would have done this)
Not french or even car related i know
but i know some of you are a very good with this sort of thing.Thanks

I can't remember the exact steps (it's in redsn0w, but I think it's under the jailbreak option, which if I recall you need to grab the ipsw file for) but you could try going through the downgrade process to downgrade it to a proper 3gs baseband.
