Enthusiasts used Mbus/Fbus cables to flash modified original firmware. What it added:
Custom startup animations, new ringtones, and even unique menu icons. The "MADOS" Project:
There was a legendary attempt to create an open-source OS for these phones, though it remained mostly a hobbyist proof-of-concept. 2. Nokia 3310 3G / 2G (Reborn 2017) The "reimagined" Nokia 3310 (2017) by HMD Global runs on Series 30+ (or Smart Feature OS for the 3G model). Custom ROM Status:
