Had the exact same issue.
> Original battery was toast. Phone restarted every couple of minutes
> Bought non-OEM battery on eBay.
> New battery worked a bit.
> Still restarting.
> Apple store.
> Won't fix. Not original battery. Won't fix anything. Apple will not touch my phone now.
> Connect phone to iTunes to reset all data, maybe restart issue?
> iTunes does a thing, like normal.
> Phone get's loading bar (for restore). Stops. Dead. Just like this post. I don't know why.
> Message eBay seller.
> Sends new batt.
> New non-original batt. Install.
> Same iTunes issue.
And dennn,
The last thing I did before my phone started restoring was removed dust from the lighting port. There was only a small amount. *Shugs shoulders* mayyyybe that was it? I held the cord flexed upward to help the pins make a better connection while the restore happened as maybe it was a pin issue? The restore happened and now I am in the testing phase to see if the restart issue continues. Interesting to note the new battery did not change the iTunes issue. AND the phone restored with non-OEM battery.
Battery issue -> 2.5 months, ongoing.
iTunes issue -> 1 month, complete.
Unrelated, what's left is I need to replace my charging port assembly. The ribbon was cut and I have no headphones. And the screen works but has seen better days.
