Lumia 630 not updating

Hi anyone,
I was trying to update to WP8.1 Update 1 on my Nokia Lumia 630.
Had plenty of space and a reliable internet connection, but for some reason, I am getting the error:
"The update was downloaded, but couldn't be opened".

I know this is happening to a few Lumias, HTCs and Samsung devices, so I'm not the only one!

Anyone else having this issue on Lumia 630?
I might restore using NSU for Retail to see if that solves it.

EDIT: My other Windows Phone device, Huawei Ascend W1-U00, took the Update 1 upgrade fine. Just left with my Lumia 630 :(

Same here. I tried many time but failed.

It's quite annoying, my Huawei Ascend W1 took the update fine!

Which version?
My RM-976_1115, UK SIM free updated and works with GDR1 OK.

I have the exact same version as you, I just get the error when trying to update!
Trying to revert to factory version as had .899 previously, before GDR1 came out!

Going to try and revert to .845 using NSU for Retail.
