    Default No WiFi / No Baseband recurrent issue

    I have been repairing and unlocking iPhones pretty much since they were released, and I have one problem that's been completely aggravating me to this point. It seems like many people are having this problem, and I've personally encountered about 9 or 10 phones in this condition. There seems to be no known solution to this, I have searched high and far for one...

    The symptoms:
    • No WiFi, because the baseband is erased.
    • IMEI is invalid (making warranty replacement impossible thanks to the Apple "genius bar" crew).
    • In most (not all) cases, a LOT of heat is generated slowly over time while the phone is running. It can reach the point where the comms board shielding is too hot to touch. This heat will eventually damage the logic board/screen if left unchecked.
    • Slow/lagging UI. Especially apparent and annoying when trying to press letters on the virtual keyboard. Unloading commcenter will remove the lag (and IIRC, the heat as well).
    • "Repair Needed" dialog, again because of a blank baseband.
    • bbupdater -v output: Baseband unresponsive to pinging.


    UPDATE:
    I have figured it out. See this thread for more info: http://www.hackint0sh.org/forum/showthread.php?t=19204

    Looks like there's a power management chip that shorts out when you connect the phone to some non-standard chargers. This is what causes the overheating and eventually kills the baseband, among other things.

    Default same wih me

    hi there, i do not kno the answer, but this may help you, i did NOT unlock my friends iphone, i just activated it via jailbreakme.com. What the deal was, my friend already has xingular, so i did not need to unlock the phone for him, just needed to be activated, ONce did, after 3 months of using it, it finally showed up saying, repair iphone needed. No wifi, no IMEI unvailable, no ICCID even with the stock SIm that att supplied. what do you think? ALSO. my friends was new bootloader, version 4.6 and was running iphone 1.1.1 firmware.

    Do you know if he had dropped the phone? I have a feeling this might be caused by physical damage.

    Yep I have 2 iPhones with the same problem. Namely no wifi BT but phone usage is ok. Revirginized with ieraser and .eep and fls the baseband. Using an iPod charger instead of an iPhone or iPod touch charger will overheat it and knock out wifi and bluetooth (shows 00.00...) and "no wifi" greyed out.

    I successfully coaxed one of the phones into wifi life for about 3 weeks and then the bluetooth failed. On trying to re-virginize to fix the BT issuei the no wifi issue popped up again.

    There are so many people that have tried to update to 1.1.1 and have the no wifi in conjunction with bad IMEI and revirginizing will fix their problem.

    What we need is a foolproof way of reactivating the baseband and re-engaging the wifi bt parts of the phone.

    Remember that the pre 1.1.1 upgrade via independence relies on having wifi.

    Does anyone have a consistent and repeatable solution for this problem?

    You have to replace (or repair) the logic board. That's the only solution. The problem really doesn't lie with the software at all - once the logic board is replaced all the weird glitches go away.

    Thanks Jdiaz. How are you sure that it is the logic board? and not the comms board?

    Cheers
