    Did your phone only had no imei? You could check if your phone also had no wifi, no bluetooth and no baseband.

    If yes, then you have the same problem Along with my iphone4.

    My phone never falldown, suddenly when i update to 6.1.3 from 5.1.1, the baseband is corrupt.

    I tried to restore Along with Itunes, ended Along with error -1, that means, apple server have problems Along with verifying the phone baseband.

    Some people said, you can fix the error -1 Along with custom firmware (no BB firmware), and i can say that, yes IT WORKS!. But ONLY restore your firmware, no upgrade or re-install your baseband. So your phone will be always no wifi, no bluetooth, always searching and no baseband, no imei.

    So all i can think is, this is hardware problem. Try re-heat the baseband chip first or replace the BB chip. I havent tried this yet. Since i hope this is software issue, not hardware.

    But as far as i heard, if replace BB chip, IMEI also will be change. What happens Along with apple server, if they check iphone serial number have different IMEI in their database??

    if it is searching Along with and Along without sim Just connect to itune and install an application ur problem solved……..

  9. TechWorld says:

    check under microscope if you have the blue resistor between the 2 antena connectors. If no, just make a jump Along with a wire. Phone gets signal in secconds

    or check this:

    iphone 4 no signal problem just serching and no servce

    hey guys,

    i have a similiar problem, but i noticed a small difference.

    it always says searching until i plug the device on my computer and connect it to itunes, than it says locked sim and it wants to be unlocked.
    the phone gets signal and everything is looking good…. until…
    i reboot the phone. Then it says again searching and the game starts over again.
    What i also noticed is, that when it says searching the imei is missing(not visible in general) and my modem firmware is empty. when i do connect the device the imei is fine and also the modem firmware….

    any suggestions?

    thanks a lot
