The is a utility used primarily for backing up and restoring Non-Volatile (NV) items —specifically the IMEI number—on Qualcomm-based mobile devices, such as older Samsung Galaxy models . It is particularly useful for recovering lost network connectivity or IMEI information after a firmware update. Prerequisites
The is a specialized utility primarily used by technicians and advanced users for managing the Non-Volatile (NV) memory of Qualcomm-based mobile devices. It allows for the reading, writing, and backup of critical configuration data stored in a device's NVRAM. Key Functionalities nv items reader writer tool
Non-volatile (NV) memory items are critical for storing configuration parameters, calibration data, and state information across power cycles in embedded systems. However, direct manipulation of NV items during development, debugging, and field updates remains challenging without a dedicated tool. This paper presents the design and implementation of an – a cross-platform utility that allows engineers to read, write, verify, and backup NV parameters from external hosts via standard interfaces (I²C, SPI, UART, or debug protocols). The tool incorporates error-checking, checksum validation, and item-level metadata parsing. Experimental results on an ARM Cortex-M platform with EEPROM and Flash-based NV storage demonstrate 100% read/write integrity, 95% reduction in manual debugging time, and seamless integration into CI/CD pipelines. The tool is released under an open-source model. The is a utility used primarily for backing
But what exactly is an NV item? Why would you need to read or write one? And how do you use this tool without bricking your device? It allows for the reading, writing, and backup
