Equipment required: Tait Programming Kit (TP94 cable), Windows 10 PC, Tait Flash Loader Software v3.6 or higher, and a stable 13.8V DC supply (≥5A).
Risk level: Low. No bricks reported in 2021 field tests. 7010b radio firmware update 2021
The 2021 firmware replaced the fixed 300ms hang with a 4th-order polynomial compensation based on the internal thermistor. This reduced the hang-time variation from ±450ms to ±35ms across -30°C to +60°C. Equipment required : Tait Programming Kit (TP94 cable),
The touchscreen on the 7010B is resistive, not capacitive, so it will never feel like an iPhone. However, the 2021 update tweaked the calibration settings, making the interface feel slightly "snappier" and reducing the frustration of having to tap an icon three times to register a press. The 2021 firmware replaced the fixed 300ms hang
If you own a two-way radio model that operates on the 7010b chipset or platform (common in brands like Baofeng, Pofung, Retevis, and certain commercial LMR radios), you have likely encountered the term "7010b radio firmware update 2021" in forums or technical bulletins. While 2021 may seem like a few years ago, the updates released during that period remain the gold standard for stability, feature enhancement, and compliance. This guide will walk you through everything you need to know: why the 2021 update matters, how to safely install it, and the critical improvements it brings to your device.
For analog FM, the 2021 update introduced a pre-distortion filter that adjusts the modulation index based on the selected channel bandwidth (12.5 kHz vs 25 kHz). This reduced adjacent channel power from -65 dBc to -72 dBc at 12.5 kHz spacing, meeting the stricter 2020 interpretation of the rules.
