What is the Coolsand RDA IMEI Repair Tool?

The Coolsand RDA IMEI Repair Tool refers to software utilities and procedures used to read, repair, or restore IMEI and related radio configuration data on devices whose baseband or modem firmware is based on Coolsand platforms (RDA/Coolsand SoCs). These platforms are common in many feature phones and low-cost Android devices. “IMEI repair” typically involves writing a correct International Mobile Equipment Identity back into the phone’s non-volatile storage (NV memory) when it’s been erased, corrupted, or mismatched due to repairs, flashing, or hardware replacement.
