How to fix some mysterious problems.

Hello All, I originally had a 3gs (new bootrom) that was jb'd using redsn0w and also updated bband to 6.15.00. This was only shortly before the greenpois0n was released so I didn't bother to put SIM in and use it. i have now followed instructions here:

http://www.shoutpedia.com/how-to-jailbreak-ios-4.2.1-with-greenpoison-rc5-on-iphone-ipad-and-ipod-touch-guide-7890/

i dl'd a custom 4.2.1 from a website, put phone into limera1n DFU as directed to in above link, and then shift+restored to that custom ipsw in itunes. this left my phone in "emergency call only" iphone screen. I then ran gp, and then ran redsn0w (with "install cydia" ticked only) which hacktivated the phone. i then put my sim card in and it only showed 1 bar without any network provider next to it. i tried making a call and it would go straight to "call failed." I instaled ultrasn0w and this just changed it to "searching..." for a long time until it finally went to "no service".

I went through the entire process again and now it just says "No SIM" and wont even recognise that a sim card is in the phone. I have used 3 sim cards and no change.

I should add that while the phone was tethered jb'd, my sister organised with the original network to have the phone factory unlocked, without my knowledge.

sorry for the long post, but wanted to be as descriptive as possible.

any help would be appriciated.

Thanks

Try installing 4.2.1 again and JB with GreenPois0n.

Install Cydia & unlock with Ultrasn0w

If it's factory unlocked, you should just do a normal iTunes restore. Unfortunately you installed bb 6.15, so that won't work anymore. While 6.15 is installed, you must use custom firmware. I'm not sure if factory unlock gets applied then. I would try to generate a new firmware which is hacktivated. The one you used wasn't. There's also a tool in Cydia to activate again (SAM).

Hi, I did try this also.

Because its on 6.15.00 I had to use custom ipsw. When gp finished, it was still unactivated, and then I ran redsn0w installing cydia to hacktivate it. I still have "No SIM" and cannot get rid of it.

Thanks

hi http, thanks I dont have a mac so cannot create a custom one, and I have looked everywhere for one that is specifically hacktivated but cannot find one, i don't suppose you know where I might be able to find one?

i will try SAM now and see if it an activation issue.

Thanks

i de-activated with SAM, however because it's saying that there's no sim card installed it wont activate in itunes.

Thanks for the suggestion. Does anyone know if a hacktivated 4.2.1 ipsw for 3gs is available anywhere online?

please guys,

anyone had any experience with "No SIM" before?

best way to start from scratch now that I have 6.15.00?

I have tried again. Put phone into redsn0w DFU mode, installed custom ipsw in itunes, jb'd with greenpois0n, then installed cydia with redsn0w to activate.

when I ran it the first time, i did have one bar/no service so at least the sim card was being acknowledged. If i can get back to that I am sure I can fix it with SAM.

please please please help!
