I am on Cyan now without downgrading. Here's what I did:
1. Download Nokia Software Recovery Tool
2. Open it and Connected my phone
3. A message pops out "A Software update is available"
4. I pressed Update
5. Confirms it and warns me that my personal data will be lost and advised me to backup my data.
6. Removed SD card from my phone to avoid file loss and backed up my settings/contacts
7. I continued the update and downloads 1.5 gb
8. Asks for confirmation to install the update.
9. Pressed install then phone restarted, Nokia symbol flashing colors and a progress bar pops out
10. Disconnected phone from PC after it's done
11. Sets Wi-Fi, language, time, and my Microsoft account.
12. Lumia Cyan now installed.
Note: This will remove you from the dev preview channel and if you were running 8.1 update 1, this will downgrade your phone to 8.1 but with cyan and can be easily reverted by following what I did below:
13. Goes to store and downloads preview for developers
14. Installed 8.1 update 1 for about 15 mins
15. Restores previous settings
16. Inserted my SD card and see all apps & games installed
Windows 8.1 Update 1 now installed with CYAN firmware

Can't post photos though, sent from my phone. Good luck!
