While official support for the Nokia X2-01 has long since ended,
Q: Will this update allow me to use 4G / VoLTE? A: Absolutely not. The Nokia X2-01 is hardware-limited to GSM 850/900/1800/1900 and EDGE. No software can add 4G.
Furthermore, most modern computers (Windows 10/11) no longer support the flashing software required. You will need a Windows XP or Windows 7 machine with legacy USB drivers.
Warning: Flashing firmware carries a risk of "bricking" the device (making it unusable). Only proceed if you are comfortable using service tools. Firmware Update on NOKIA X2-01 - HardReset.info
However, like all software, the Nokia X2-01’s operating system (S40 – Series 40) is prone to bugs, performance lags, and compatibility issues with modern network standards. The last official firmware release for this handset was version 8.75. Many users report that updating to 8.75 fixes random reboots, improves Bluetooth stability, and speeds up the phonebook.
