Thread: no service quickpwnd could it be hardware failure?

  1. #1
    Default no service quickpwnd could it be hardware failure?
    I just picked up a 4GIG 2G iphone today. It has a seriously cracked screen (impact at the top of the screen) and I got it 2.2.1 unlocked from craigslist. Works ok, but when I got home and put my (tmobile usa) sim in, no service errors.

    I do get the carrier option in settings-general-network, and there's no error about my sim. It just doesn't seem to be able to get a gsm connection. When i go to carriers, it often says Automatic, ATT; sometimes ATT and TMOBILE, and more often than not 'Unable to load network list'

    The blue bars do seem to vary, indicating different levels of signal strength.

    I tried restoring via itunes, then running the latest quickpwn.

    I tried turning airplane mode on and off several times, and resetting network settings and rebooting.

    I tried another tmobile sim, same results.

    I tried a friend's ATT sim. This had the same basic results, but I did get the ATT carrier icon, and it seemed like it came up 'searching...' a lot less. ATT icon, full bars, but when i tried making calls, recieving calls, sending texts, it always failed.

    So... i'm wondering if this could be a hardware failure? I can't really trust the history I got from the craigslist dude, and by the looks of the screen it did take a hit. Everything else works on the phone (appstore, wifi, cydia, xcode dev), could it be a bad GSM module, antennae, or possibly a software issue i've overlooked?

    Just another quick question- sorry this is in iphone general instead of a unlock specific forum, but the original question was more of a general 'what kind of things could go wrong with gsm connectivity other than the stuff i've already looked at'

    Is the baseband affected by a full itunes restore? I'm wondering, because i was thinking one way to fully isolate the problem from my tmobile sim/quickpwn efforts, would be to do a itunes restore (it's an old 4G 2g) and then take it into att to get a month of prepaid for it. Then I'd have an ATT sim and legit activation. Thing is... i'd really rather not spend that money- especially if itunes restore doesn't remove the problem.

    baseband wouldn't have been updated. sounds like a hardware issue

    Try doing a full restore, no jailbreak. Put your friends AT&T sim in there and give it a go. If it doesnt work, then put that badboy back on craigs

    Thanks for the tip- I picked it up for development, just hoped I could use it as a phone too. It's cheap enough that I can just get a G1 and have em both to play with.

    Are there known hardware failures that can lead to this? I'm not sheepish about cracking it open to fix a loose connection or something.
