Phone won't start up.
The iPhone “iPhone” could not be updated. An unknown error occurred (75). 067E.004B
iPhone SE (first generation).
The phone started shutting off and restarting and it went into continuous restarting mode.
I followed the steps from the apple page, but it went to restore mode. I connected the phone to my iMac, then clicked restore, but it said it needs to update before restoring. I clicked update, and, after all the steps, I got error code 9. I tried different USB cables. I tried a different computer, but I either get error code 9 or 75.
