Thread: ultrasn0w giving 'no service' with iphone 3g, 3.0

  1. #1
    Default ultrasn0w giving 'no service' with iphone 3g, 3.0
    Upgraded to 3.0, jailbroke iphone, unlocked with ultrasn0w (without doing ANYTHING else in between), and im getting a 'no service' error. I'm using an american iphone in the UK with an o2 card that was working on 2.2 unlocked with yellowsn0w. when I go in the carriers list, I see the o2 carrier and I can select it, but it gives me no service.

    I've tried this about 4 times. i've even tried ssh-ing and installing the .deb file of 0.6 ultrasn0w through mobileterminal. but that didn't work either. any ideas on how to fix it?

    I've had similar problems but for me Edge works. The moment I enable 3G, I get "No Service". Any solutions?

    Restore to 3.0 stock. Re-run redsn0w 0.8 to jailbreak and reinstall ultrasn0w .091 to unlock. Start all over from scratch.

    Default Maybe a hidden TurboSim inside the phone
    There are probably many reasons for no service after jailbreak and ultrasn0w, but I wanted to let y’all know what happended to Qty 2 3G phones I bought in Malaysia. Apparently, they were unlocked phones bought in Australia and brought into Hong Kong and “fixed” prior to being shipped to Malaysia. The phones originally worked fine with just about any SIM, however over time they started loosing service and with 3.0 and ultrasn0w they became close to hopeless.

    With the custom 3.1 ipsw and the 3.0 baseband, I started getting No Sim. I took the 2 phones to an “iphone doctor” and decided to open up the phone to see if I might have broken some SIM contact pins:

    Surprise Surprise: On the very bottom of the circuit boards, we found a TurboSIM of some sort glued on with thin copper wires running up to the SIM card holder…. We removed it and both phones are working fine.

    How about them chinese…

    Default Same problem after upgrade in cydia
    I haven't been in cydia in months and I usually never upgrade anything (don't fix it if it ain't broken). But for some reason I upgraded my ultrasn0w to v91 and now I get no service in places I've always gotten service. I lost service for 5 hours Sunday and it's intermittent at home. I have no idea what's going on. 3G is not on, rebooting, toggling airplane mode or popping the sim doesn't work. Last resort is to restore but all I did was just upgrade my ultrasn0w. I have tried removing it and resintalling it in cydia. Will a fresh install of FW and ultrasnow even fix that?

    *edit*

    I tried a restore with a custom 3.0 and 3.1 and am still getting no signal every once in a while. Please help!

    After installing the Ultrasn0w repo did you search cydia and install ultrasn0w?

    ... yes...

    I still get service, I just keep losing it. The difference between no service and 3-4 bars can be as little as 1 foot away which makes no sense.

    I've restored to 3.0 using PwnageTool and redsn0w and upgraded to 3.1 using PwnageTool, then installed ultrasn02 v91 through Cydia. No luck. I even did an offline install of ultrasn0w v6 and still no service inside buildings. I've read some things about MMS settings interfering with and have tried clearing them to no avail. I'm all out of ideas.

    If you have Tmo, you have to turn off 3G to get service (in some cases it doesn't affect service). Tmo's 3G doesn't work with the iPhone anyway due to different frequency capabilities so it's pointless to keep it on.
