As stated in the title my Surface Pro 3 won't upgrade to 10122. It downloads, restarts, tries to apply the new build, but then restores 10074.
Error 0x88870757 - 0x20007
Any ideas?
This looks like a promising solution:

They ran it 5 times and the upgrade worked. I ran it about 20 times and it is now past being stuck.
