This error typically occurs when using engineering tools (like Maui META, SPD Upgrade Tool, or QPST) to restore or repair a device's IMEI number. It indicates the software cannot write the new IMEI to the phone’s NVRAM (Non-Volatile Random Access Memory) or modem partition. (Comment replies would suggest: Check NVRAM partition size,

Do I need a patched DA file? Thanks.
