I can't update to windows phone 8.1! Please read the details!!!

I know that it will sound very stupid, but I just don't know what to do. I need a favour. I have just bought a Nokia Lumia 1520 and its version is windows phone 8. I want to update it, but Windows Phone 8.1 is not supported. The other way is using "Preview for developers". With the second method you need to have an app studio account, but the thing is that app studio is closing and I can't create a profile. Only existing accounts can login. So there is the part where I need a favour. Can you please give me your login details for app studio. If not can you please help me somehow- give some pieces of advice if it is possible to update otherwise. Thank you in advance.

I tried this on an old 920 just out of curiosity, and it worked fine.

Use the Windows Device Recovery Tool. It will install the latest firmware onto your device, which is either Cyan or Denim (both come with Windows Phone 8.1). Be advised that you will lose all data on the phone, so it is advisable to do a backup.
