If you are looking to fix baseband issues, repair IMEI, or manage modem settings on a Qualcomm-based smartphone, the NV-items Reader Writer tool is a critical utility. This specialized software allows users to interact directly with the Non-volatile (NV) items of a mobile device's modem, which store essential configuration and calibration data. What is the NV-items Reader Writer Tool?
The NV-items Reader Writer is a small but powerful utility designed for devices using Qualcomm chipsets. Its primary functions include:
Reading NV Items: Extracting current configuration data from the device's modem memory to a local file (often in .txt or .nv formats).
Writing NV Items: Modifying or restoring specific data points to the device to fix connectivity or hardware identification issues.
IMEI/MEID Repair: Frequently used by technicians to restore original device identifiers after a software crash or firmware corruption.
Carrier Aggregation Control: Advanced versions can be used to decode specific NV items (like 00028874) to see which frequency bands and carrier aggregations a phone supports. Key Features of the Tool Last updated: October 2025
Portable Utility: Usually available as a small .zip file that doesn't require a complex installation process.
Diag Mode Support: Works by communicating with the phone via the Qualcomm Diagnostic Port (Diag Mode), which must be enabled on the device first.
Backup & Restore: Essential for creating a safety net before performing risky firmware updates or band unlocking. How to Use NV-items Reader Writer
Using this tool requires caution, as writing incorrect values to the wrong memory address can permanently damage your device's modem.
Enable USB Debugging: Go to your phone's developer options and enable USB debugging.
Enter Diag Mode: Use a dialer code (like *#0808# on some models) or an ADB command to put your phone into Diagnostic Mode.
Install Drivers: Ensure the Qualcomm HS-USB QDLoader 9008 drivers are installed on your PC so the tool can "see" the device.
Connect & Read: Open the tool, select the correct COM port, and click "Read" to back up your current NV items.
Write (If Needed): To restore a backup, browse for your saved file and click "Write." Safety Warning
Important: NV items contain unique device data such as calibration parameters and network identifiers. Never write an NV file from a different phone model to your device, as this can lead to a "No Service" issue or a hard brick. Always perform a "Read" and backup your original data before making any changes. Where to Download In the world of database editing, save game

Because this tool deals with low-level data, many free download sites bundle it with adware or malware. Never download from pop-up ads or unknown file-sharing forums.
Use unzip nv-items-reader-writer-tool.zip -d nv-tool in the terminal, then run the Java version via java -jar NV_Writer.jar.
Functionality: ⭐⭐⭐⭐☆ When the correct Qualcomm drivers (such as HSUSB Drivers) are installed and the device is in the correct mode (usually Diagnostics Mode/Diag Mode), the tool is remarkably fast. Reading the entire NV partition takes only seconds. The read/write success rate is high on supported chipsets (Snapdragon series).
User Interface (UI): ⭐⭐☆☆☆ The interface is strictly utilitarian. It resembles legacy Windows 98/XP era software. It usually consists of a simple "Connect," "Read," and "Write" button set, along with a log window. There are no tooltips or "wizard" style guides. The UI assumes the user already knows what NV item #550 represents.
Ease of Use: ⭐⭐☆☆☆ This is not a "plug-and-play" tool for the average consumer.
