If a standard flash doesn't work, you likely need to repair the NV partitions directly using specialized MTK tools.

If successful, the "Nv Data Corrupted" message vanishes, and the IMEI returns. The "Earth" is restored, and the Poco C55 or Redmi 12C lives to see another day of scrolling. Why It Matters
When you “develop a proper feature” for the file content, you need the correctly mapped:
Encountering a "NV Data is Corrupted" error on your POCO C55 or Redmi 12C is a solvable problem. By understanding the nature of NVRAM and NVDATA, you are already equipped to approach the issue logically. While the problem may seem complex, the solutions range from using a simple dedicated tool to performing manual IMEI writes with the Modem META tool.

Both the POCO C55 and Redmi 12C are powered by MediaTek (MTK) processors, a detail that is central to understanding their data storage architecture. The Non-Volatile RAM (NVRAM) and NVDATA are partitions on your phone's internal storage that act as a secure repository for device-specific configuration data that persists even when the phone is powered off. They store crucial identifiers, including the International Mobile Equipment Identity (IMEI) numbers (unique identifiers for each mobile device), Wi-Fi and Bluetooth MAC addresses, and radio calibration settings for network connectivity (Baseband).
Flash the factory-fresh partition binaries back to their designated memory offsets: mtk write nvram nvram.img mtk write nvdata nvdata.img Use code with caution.

Given that the phones are near-identical under the hood, the decision comes down to aesthetics and availability. If a standard flash doesn't work, you likely
If your unique NV data has been wiped out completely, you must force the system to regenerate base variables by restructuring the firmware layer:
Choose the manual format addresses dictated by your firmware's scatter file. Wipe the specific blocks allocated for nvram and nvdata . Step 3: Flash the Clean NVRam and NVData Files Load the official firmware scatter file into your tool. Locate the specific rows labeled nvram and nvdata .
