    Default ultrasn0w noservice (solved)

    I did the usual chore using: PwnageTool then installed Ultrasn0w following
    http://www.redmondpie.com/jailbreak-...l-3.1.4-qwo969

    I have tried everything in the post and they all failed (I kept on getting *noservice*)
    NOTE: turn off/on (airport/3g/data roming) this usually works but didn't this time.

    The problem was my baseband version; I had an old (2.x) baseband (as i never upgraded the baseband)

    How to check baseband: settings->general->about->(Modem Firmware)

    Solution:
    update/downgrade baseband (modem) using: FuzzyBand (find it at Cydia) NOTE: I upgraded my baseband to 04.26.08 as this is the latest base band supported by Ultrasn0w

    Cheers

    I was having the same problem with my service dropping, until I disabled Notifications. At least it's been good the last few hours.

    My theory is this - I don't have the data package on my Tmobile account, but with notifications on, Facebook, Ebay, ETC are trying to get updates. When you have Wifi close, everything is peachy because there is connectivity. When you aren't in Wifi range, there must be some sort of timeout that causes the cell service to drop too. Sooooo if you don't have data service, turn off notifications.

    Cross your fingers - and post if that fixes your issue.

    Unless you can use fuzzyband to downgrade baseband - your only unlock option is ultrasn0w 0.9.3

    Hi,
    now im very new to this, but i have my phone jailbroke and installed ultrasn0w and tried your method.
    ive tried it several time, no wifi, on wifi and on all occations nothing happens and i lose signal, after trying what you say it goes into searching for hours and nothing.

    i live in portugal and my phone runs off of optimus and i want vodafone.

    running on 4.21 and 05.15.04
    sorry phone is 3g

    only way to regain signal is to uninstall ultasn0w

    thank you in advance

    any ideas

    this is step by step:
    1. after install ultrasn0w, turn off 3G and reboot, and insert simcard
    2. don't press OK or just leave if have warning "no simcard inserted"
    3. wait for "no service" and turn on airplane mode
    4. take off simcard, n insert simcard again
    5. turn off airplane mode
    and ur service will be back

    tell me if this way can work..
    2 years later and nope...didn't work on iOS 4.3.3 1.59.00 BB and ultra 1.2.4 (same problem though)
