WP8.1 GDR1 - update downloaded couldn't be opened

People, please test this procedure before you hard reset or use the Nokia recovery tool. I had the 8018830f error like 10 times, it always downloaded but install failed. After changing language and region to UK it went further. I'm now at the spinning cogs screen installing the update.

I'm in the UK worth an official UK device and it's not working for me :/
 
My Lumia 925 (India) facing the same problem.........
It says - The update has been downloaded, but was unable to install due to some error (8018830f)wp_ss_20140804_0001.pngwp_ss_20140804_0003.png

i had the 0x80188308 on my lumia 822 i changed the language to french then downloaded and it installed
 
925 Cyan in the UK, but was on US Region and settings to get Cortana. Have switched back to UK. Have removed US entirely. Rebooted many times.

Tried the update after reboot, have 17gb free, but still getting the error.

Oh well it's a developer preview so I'm not complaining and I'm sure it'll be resolved soon, but I'm just impatient to have the newness!
 
My battery was at 100% and on charger.. It's not that.
Battery less than <50%
charging now to see if it's that!
I had set phone to US for a few weeks to try out Cortana, but switched back 3 or 4 weeks ago, to UK.
trying to think of anything unusual about my phone...
 
wait!!what? Cyan is not for DP for now,you are mistaken,if you need cyan u have to revert back to windows phone 8 using recovery tool i guess,then only u could install official 8.1+cyan..

Thanks for the suggestion, but unfortunately not working for me. Will wait and see what suggestions others come up with before doing a hard reset.
