3gs sound loss with 4.3.1

Immediately after uprgrading to 4.3.1 and jb it i began intermittently losing all sound. no mic, no speaker, no ear speaker, and no headphone jack. A few hard restarts would fix it. now a couple days later i had lost all sound. so i restored the phone without a jb. same problem. however after a few hours i got my headphone jack and ear speaker back. i am going to open it up and see if theres a loose cable on the dock connector tomorrow when i get home. what else could cause these complications though?

structure412, I think that if nothing has happened to your iPhone, like getting dropped or water damage, that there is know reason to tear it apart. I would think that the problems are caused by your recent update. Have you tried to try to use the firmware that you had before you upgraded. The way I look at it is, if it worked before the upgrade but not after, should repair the upgrade. Firmware is available right here and here is a good forum that might assist you further. Good Luck and let us know what happened.

well i just replaced the dock connector a few weeks prior to this event so i was wondering if maybe a cable came loose. but i did try to restore to 4.2.1 from that page has already stopped signing it. they are becoming a PITA like that. its to the point where you just cant update when they release it because if you have a problem you cant go back.


Have you tried to downgrade your phone since all the trouble started after the firmware update? I don't think that in absence of any damage to the phone that dis-assembly would be a good idea. The trouble started with your update, so that is where I would start to trouble shoot. Great forum about that on and here!5572003/how-to-d...[s]-from-ios-4-to-ios-313 and the firmware is available at Check it out and tell us what you think,


Agreed. I'd start there before I would reopen the phone. +


I'd try oldturkeys suggestion, it would be pretty disastrous to have ruined ALL audio output from changing the dock (which has mic and speaker but not headphone and earpiece on it) unless you have damaged the audio ic which is under the shield..


would it be worth it to try the new update, 4.3.2 before all of that?
