The T-7010B utilizes an STM32 processor which requires entering "DFU Mode" (Device Firmware Upgrade) to accept a new flash.
Even though the flash is new, residual EEPROM settings may cause conflicts.
Warning: A full update is more thorough but also riskier. If interrupted (power loss, cable disconnect), the radio can be "bricked." Backup your codeplug first.
| Symptom | Likely Cause | Fix | |---------|--------------|-----| | “Device not recognized” | Wrong driver | Force install the manufacturer’s .inf driver (disable signature enforcement) | | Update stalls at 50% | USB CRC error | Retry with shorter cable, lower baud rate (if configurable) | | Radio shows “FAIL 01” | Bootloader mismatch | Reflash bootloader using DFU mode and a full image | | TX audio distorted after update | Calibration table overwritten | Reload saved calibration, or perform deviation adjustment (2.5 kHz ±0.2 kHz) | | Zone data missing | Codeplug version mismatch | Manually recreate zone/channel list; do not force-write old codeplug |
