Before flashing anything, run this in CMD: thor2 -mode uefiflash -backup -backuppartition GFP_NVE This saves your phone's unique calibration data. Lose it, lose your gyroscope and battery meter permanently.

This is the most headline-grabbing development. The Lumia 520, despite its age, can run full desktop Windows 10 — not Windows Mobile. However, the 520 is the absolute minimum spec.

The ROM: Windows 10 ARM64 (Build 1709)

The Experience: It takes 15 minutes to boot. Once you see the desktop, you can open Notepad and Paint. Browsing the web is impossible (512MB RAM can't render modern Javascript). However, it is a fantastic proof-of-concept showing that Microsoft's own phone could run desktop code if unlocked.

Warning: This is not for daily driving. This Nokia Lumia 520 Custom Rom is for hobbyists who want to see the Windows logo spin on a screen that cost $80 a decade ago.

My rating: 6/10. Only do this if you are bored. The stock WP 8.1 is actually faster.
