It sounds like you’re looking for a deep technical explanation of the NVData / NVRAM partition files for the Poco C55 and Redmi 12C (which share the same MediaTek MT6765G / Helio G85 chipset).
Let me break this down thoroughly — including what these partitions are, why they matter, how they differ between the two phones (even though hardware is nearly identical), and how to extract/restore them. To summarize the critical takeaway for your search
When you “develop a proper feature” for the file content, you need the NvRam region layout correctly mapped:
| NvRam Region | Feature Provided |
|--------------|------------------|
| RF_Cal (0x100–0x2000) | Restores RX/TX gain, frequency response, antenna tuning. |
| IMEI1 / IMEI2 storage | Two 15-digit slots + checksum. |
| MAC_WLAN | 6-byte Wi-Fi MAC address. |
| MAC_BT | 6-byte Bluetooth MAC address. |
| SN_Number | Device serial number string. |
| Security_Zone | DRM keys (Widevine L1 – if originally present). |
| Barcode_Data | Shows correct IMEI in dialer *#06#. | Your Poco C55 or Redmi 12C is recoverable
⚠️ DRM/Widevine keys cannot be restored from another device – they are unique per unit.
The codename earth is shared between the Redmi 12C and Poco C55. Internally, they are identical. This means:
However, here lies the critical warning: You cannot download a working NVData file from a forum (4pda, XDA, GSM-Forum) and flash it to your device.
Why? Because every physical phone has a unique set of calibration data. If you flash someone else's NVData:
