Updating phone firmware
", stuck on 0% while plugged into charger all night long without any progress, no response from any button or button combination; not even 2 minutes of holding down the power button. Remove the tiny screws and remove the plastic part to get to the battery.The battery didnt appeared to be removable, but at the top left a flat short cable pops out of the battery and its terminal can be unplugged.I charged it enough to get into their unlocked phone and found enough clues to find the owner (but no nudes ;-).When I plugged the phone in again to give it a full charge before mailing it back it did this stupid firmware update stuck on 0% thing. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).I fixed it by just holding the power button on the right and the volume up button on the left for a few seconds. Would you like to answer one of these unanswered questions instead?
Then leave it out for a few seconds,a battery with a red exclamation point should show up and that is when you insert the battery and turn it back on. What worked for me : Remove plastic snap on back cover.
When you restore an i Phone, it erases the i Phone back to factory settings updates it to the latest version of i OS, so you’ll end up with a blank i Phone running i OS 10.
If you have an i Cloud backup, you’ll be able to sign in and restore from your backup as part of the setup process — just make sure you know your Apple ID and password.
When your i Phone updates to a new version of i OS, a lot of the low-level software gets replaced.
If your i Phone is stuck on the connect to i Tunes logo after updating to i OS 10, it means that the software update started but didn’t finish, so your i Phone can’t turn back on. Yes, it’s a serious software issue — but almost all software issues can be fixed at home.
