I will try a quick Summary:
- The old 10080 Build is also known as 10.0.12562.84 while the new 10136 is 10.0.12634.131
- If your update suggests 10.0.12562.84, the old update is already queued and you will likely
have to hard reset or even flash back to 8.1 with WPRT to get the new update.
UPDATE (Gabe/Twitter): Hard Reset will be enough. Unfortunately you will still lose your settings.
- Download Server get pretty hammered right now so just try again
- Upgrade takes up to 1 hour (First 10% are the slowest). You will see moving Gears and no
progress bar for some time.
- Don?t forget that the lock screen shows no time for about 10 Minutes after the Upgrade to 10.0.12634.131.
This is expected. Just be patient and don?t try to restart the phone.
I hope i got this right
