If you flash a ROM, stick to Windows Phone 8.1 custom ROMs. They are far more stable on the 520's hardware than Windows 10 Mobile. Treat the device as a dedicated MP3 player, a retro gaming emulator (using emulators like VBA8 for Gameboy Advance), or a bedside clock. Jpg4us | High Quality
While you will find YouTube videos claiming to show Lumia devices running Android, these are almost always fakes, concepts running via Virtual Machine apps, or simply clickbait. The driver support for the Lumia hardware on the Android kernel is non-existent. Therefore, you cannot simply flash a modern version of Android (like LineageOS) onto this phone.
