    Exclamation Carrier Problem after upgrade 3GS to 3.1

    Hello

    I jailbreak my new 3GS 3.0 4 months ago when it first launched with purplera1n. There were no problem with my 3.0. Then to upgrade for the new fw I created a custom firmware for 3.1 using my MBP and 3.1.3 pwnage tool. I restored it normally (like i've done dozen of times before). Everything was working after installation except carrier. My phone cannot see my carrier and GPS so i cannot able to do any kind of call or sms. It's not the problem of not showing operator name. The carrier menu does not showed up on the setting neither.

    Here what I've do to fix this;

    - Created different size of firmware (from 600 mb up to 1 gb)
    - Used custom firmware from my friends which they did this successfuly
    - Re-install using ATT sim card

    None of the things worked. It can easily updated but no carrier.

    I cannot restore back to 3.0, due to apple sign process and my id was not saved on saurik servers

    I've search for 1 day on google but there were no cases like mine. I will be glad if you able to help me.

    Thanks

    this problem is well known for iphone 3GS that was upgrade from 3.0/3.0.1 to custom firmware 3.1.

    It is due to the fact that you are running 3.1 firmware in combination with older baseband 04.26.08. You need this baseband so you can continue to use ultrasn0w.

    - One way to fix this is to downgrade back to 3.0/3.0.1 IF AND ONLY IF you have your ecid/shsh stored on Saurik's server. However, most people don't have this.

    - the other way to fix this is: (from Hari Taiki Blog's)

    I havenít personally tested this (canít because I am not using the old baseband anymore and canít downgrade), but a new carrier logo fix for pwned 3.1 has been found. Thanks to PurpleMan for the tip.
    If youíre on AT&T, SFTP into your iPhone (make sure OpenSSH is installed on the phone first), then browse to /private/var/mobile/Library/Carrier Bundles/ATT_US.bundle find the file carrier.plist. You need to convert it from a binary plist to plain text XML (here is a guide on how to do that: converting mac plist files from binary to xml — thirstymind.org). You may have to convert it back to binary as well when youíre done. This will not, however, fix the ďNot AvailableĒ text for the network field under Settings>General>About.
    Find where the following code is (using turkcell as an example, itís exactly the same method for all carrier.plist files in each bundle):


    <array>
    <dict>
    <key>AllowPrefixMatching</key>
    <false/>
    <key>CarrierName</key>
    <string>TR TURKCELL</string>
    <key>DefaultImage</key>
    <string>Default_CARRIER_Turkcell.png</string>
    <key>FullScreenOpaqueImage</key>
    <string>FSO_CARRIER_Turkcell.png</string>
    </dict>
    <dict>
    <key>AllowPrefixMatching</key>
    <false/>
    <key>CarrierName</key>
    <string>TURKCELL</string>
    <key>DefaultImage</key>
    <string>Default_CARRIER_Turkcell.png</string>
    <key>FullScreenOpaqueImage</key>
    <string>FSO_CARRIER_Turkcell.png</string>
    </dict>
    </array>
    In between the last </dict></array>, you need to insert the following code:


    <dict>
    <key>AllowPrefixMatching</key>
    <false/>
    <key>CarrierName</key>
    <string></string>
    <key>DefaultImage</key>
    <string>Default_CARRIER_Turkcell.png</string>
    <key>FullScreenOpaqueImage</key>
    <string>FSO_CARRIER_Turkcell.png</string>
    </dict>
    This should work for those who are with the old baseband on 3.1 after a respring. Now you donít have to rely on the ugly text done with FakeCarrier or MakeItMine. Enjoy.

    @Dtube, don't think you understood the problem totally, he does not wan't to fake an operator logo, or tweak tha it shows up, he cannot use his GSM.

    I had the same, and although I was using my iphone correct sim/operator combination I had no joy, used ultrasn0w to unlock (although it shouldn't have been needed) but now it works fine
