Tried updating my iphone
A manual reboot is done the usual way, by holding down the Sleep button and swiping the 'Slide to power off' slider when it appears.
After i Phone has shut down, start it by pressing the Sleep button.
If the i Phone stays it the Recovery Mode after the reboot, it must be restored with i Tunes.
You only option is to find a computer with i Tunes and restore the firmware when connected to i Tunes.
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.The 1671 error may be resolved simply by waiting until the Apple servers can be contacted successfully again.There are also mixed reports of resolving i Tunes error 1671 by restarting the i Phone or i Pad and the Mac or PC.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.
If your device is still stuck on the i Tunes logo screen, proceed with the restore or update process with i Tunes as recommended.
