[Problem] [Solved] iphone 2g suddenly went into "emergency dial only" mode
(i have fixed this already on the spot by running quickpwn and restoring through itunes. but why did my iphone do this suddenly):
i just unlocked/jailbroke my phone last weekend. everything was fine. itunes came up with "update to 2.2.1?" i hit "cancel" (then went to preferences and disabled the auto-check)
so later that night, i drained my battery to 0 (it kept powering off around 4%, 3%, then finally at 0%) to re-calibrate my battery
i plugged it in to my computer to charge and about 20 minutes later noticed i was at the screen with the slider that says "slide for emergency" and i think a picture of a dock cable into a itunes logo.
at the top, my carrier still said t-mobile, and i think i heard a new mail notification as well
i tunes said "invalid sim detected!" and wouldnt let me do anything so, i fixed this by putting the phone in some sort of restore mode. then itunes recognized it as an apple boot something or other which let me restore it (shit-click on restore, browse to a 2.2 downloaded firmware version i originally used to jailbreak/unlock the phone). ran quickpwn.. everythings fine
but WHY ON EARTH would my phone do this? by draining my battery and plugging it into a pc with itunes, did apple detect it as a phone needing the stock firmware pushed to it?
i just want to make sure this doesnt happen again. i was able to restore a backup and re-sync everything. still need to put in the new mobileinstallation file, create the "documents" or whatever folders, etc but i think im running fine so far
since im new to all this, i wanted to make sure i didnt screw something up along the way to unlocking my phone to where this could randomly happen sometimes.
