I flashed my 930 from CV PL (Poland) to 059W0X5 following the above process. Worked flawlessly, but you will need to be a bit software savvy to install all the apps and follow the process exactly. If you have a phone without SD card, make sure you backup your data. Here is how I did it:
1. Installed all the Nokia apps according to XDA post. Downloaded 059W0X5.
2. Copied all the data folders from my phone to my PC (/pictures/, /music/, /documents/, /downloads/, etc).
3. Did a fresh online backup of the phone (in phone settings, click backup phone)
4. If you use Whatsapp: Did a fresh backup from the Whatsapp settings (this ensures you get your chats back after flashing)
5. FLASH and get Denim
6. After phone updates all apps and OS (which may take 2 hours or more because you will need to delete all the rubbish it puts back), copy all your backup stuff back to the phone.
7. If you use Whatsapp your chats should be restored after the flashing and updating.
Good luck!
