Tried updating my jailbroken iphone
This works if for some reason your device continues to have problems with the i OS 10 update failing or i OS 10 update getting stuck.
First let’s assume you connected the i Phone or i Pad to i Tunes and used the above methods near the top of the article to no success.
Essentially this means the i Phone or i Pad will be bricked and unusable until it can be restored or successfully updated with i Tunes and a computer.
Update: Apple has apparently fixed the problem with the OTA update.
Finally, some of the impacted users who are attempting to use recovery or restore mode to restore the i Phone or i Pad may encounter an error 1671 or similar error message in i Tunes, which further complicates the trouble.*If you are jailbroken, it is my personal opinion . Select the Restore option when i Tunes prompts you.Once the restore process has completed your i Phone will restart and the Apple logo will appear while booting up.While it is connected, simply hold down the home and power button together for about 10 seconds, then release the power button while continuing to hold the home button.A few seconds later i Tunes should detect your i Phone, Select the "Summary" tab. You will now be prompted with a screen that asks if you wish to back up your i Phone before restoring.
