For the ZTE Blade L220 (often sold under carriers like T-Mobile or as a generic unlocked GSM phone), the firmware governs:

RF Calibration: Ensuring the antenna connects to 2G/GSM networks. Keypad Mapping: Making sure each physical button triggers the correct action. Power Management: Optimizing the massive 1500–2000 mAh battery. Torch & Audio: Controlling the flashlight and loudspeaker.
