The Poco C55 and Redmi 12C (codenamed "earth") are essentially the same device under the hood, sharing the MediaTek Helio G85 chipset. A common issue for power users and technicians working with these devices is the "NV Data is Corrupted" error, often occurring after a failed flash, IMEI repair attempt, or software downgrade. Understanding NvData and NvRam
The NV (Non-Volatile) partitions are critical for your phone's unique identity and connectivity:
NVRAM: Stores permanent hardware data, including your IMEI numbers, MAC addresses (Wi-Fi/Bluetooth), and baseband calibration.
NVDATA: Contains dynamic network settings and security information that interacts with the NVRAM during boot.
Why they fail: These partitions are unique to every single device. If you flash a "donor" file from another phone without proper patching, the system security check will fail, resulting in a boot loop to Recovery mode with the "NV Data Corrupted" message. How to Fix "NV Data is Corrupted"
If you are stuck in this loop, the goal is to restore the device's ability to read its network identity. 1. The "Clean" Flash Method
Sometimes, the error is caused by a version mismatch between the firmware and the data partitions.
Step: Download the latest official Fastboot ROM for your specific region (e.g., Global, India, or Russia) from trusted sources like XiaomiROM or MiUI Firmware Updater.
Tool: Use the Mi Flash Tool to perform a "Clean All" flash. This may resolve minor software conflicts. 2. Advanced Repair with Professional Tools If you need a clean Poco C55 NVData/NVRAM file for repair:
If a standard flash doesn't work, you likely need to repair the NV partitions directly using specialized MTK tools.
Bypass Tool: Since these are MediaTek devices, you often need an MTK Auth Bypass Tool to put the phone into BROM mode (usually by holding both volume buttons while connecting to a PC).
Unlock Tool / Pandora: Technicians frequently use the Unlock Tool to "Wipe NV" or "Fix NV Data".
SP Flash Tool: For manual partition flashing, you can use SP Flash Tool with a scatter file from the official firmware to flash specific images like md1img.img or donor NV files, though donor files often require further IMEI repair to function correctly. Where to Find Files
Official Firmware: Essential for extracting the scatter file and standard partition images.
Donor NV Files: While risky, some community-shared donor files for Redmi 12C (earth) can be found on sites like AndroidFileHost for testing purposes.
Community Support: The 4PDA POCO C55 / Redmi 12C thread is a primary hub for specialized "fix" instructions and custom recovery links. Important Warning
Always backup your own NVRAM/NVDATA before attempting any software modifications. If you lose your original NV files and don't have a backup, restoring your original IMEI and cellular connectivity becomes significantly more difficult and may require professional hardware service.

The and Go to product viewer dialog for this item. (codenamed "earth" or "aether") are identical hardware models that often encounter the "NV Data is Corrupted" error. This issue typically locks the device into Recovery Mode and is caused by damaged or missing NVRAM (Non-Volatile RAM) and NVDATA partitions, which store critical device-specific information like IMEI, baseband, and calibration data. NV Data Repair Overview
Repairing these partitions requires specialized software tools and specific "clean" backup files from another working "earth" device. Primary Tools Used:
DFT Pro: Used for wiping NVRAM, fixing null baseband, and patching NVDATA.
Unlock Tool: A popular alternative for flashing and bypassing FRP/MI Account locks during the repair process.
Hydra Tool: Often used for flashing the device via MTK Flash Mode.
Super Hydra: Effective for dual IMEI repair on "earth" devices. Common Repair Steps
Partition Erase: Use a tool to erase existing nvram and nvdata partitions to clear corruption. File Writing : Write a known-good backup or "NV file" from another
. Note that after writing another device's file, the phone may still show "NV Data Corrupted" until further steps are taken.
Firmware Downgrade: Some solutions require flashing the device with a specific older "Downgrade Firmware" or "Engineering ROM" to enable IMEI repair capabilities.
IMEI & Baseband Fix: Perform a "Fix Null Baseband" followed by IMEI repair (often via "Patch Cert") in flash mode.
Final Patch: Apply a "Patch NVDATA" or "Repair Network" command to finalize the connection between the hardware and the new partition data. Critical Files for "earth"
NVRAM/NVDATA Backup: Essential for restoring radio connectivity. For educational/repair use, the best “file” is the
Engineering (ENG) Firmware: Used by technicians to bypass software restrictions during the repair.
Modem Files: Can sometimes be flashed independently to fix signal issues without a full OS reinstall.
It is important to clarify upfront that searching for or using NVData / NVRam files from unverified sources for devices like the Poco C55 or Redmi 12C (often codenamed earth) is a risky practice. These files contain unique device identifiers, including the IMEI numbers, Bluetooth MAC addresses, and Wi-Fi calibration data.
If you have corrupted your NVData partition (e.g., after a failed flash, "Null IMEI," or "Baseband Unknown" error), the correct solution is rarely a random file from the internet. Instead, you need to repair the partition using official tools or a factory backup.
Below is a comprehensive, long-form article regarding the Poco C55 / Redmi 12C (earth) NVData / NVRam issue, why these files exist, and the correct recovery methodology.
Prevention is better than cure. If you use SP Flash Tool on your earth device:
If you use Mi Flash Tool (Fastboot mode), always select save user data or clean all – never clean all and lock without a backup.
| Tool | Purpose | |------|---------| | SP Flash Tool v5.2116+ | Read/write NVRAM partitions | | MTK Meta Utility | Regenerate NVRAM from scratch | | Hex Workshop / HxD | Manually edit IMEI in nvram.bin | | Maui META 3G | RF calibration backup | | ModemMeta | Write IMEI on MTK G-series |
This is a logical partition that stores dynamic system data. Crucially, it holds:
Why losing this is a disaster: If you format the "NVRam" via SP Flash Tool or flash a full firmware package without selecting the correct options (like "Format All + Download"), you will wipe the unique factory data. Once wiped, the phone has no identity on the cellular network.
The Poco C55 and Redmi 12C are beautiful budget devices. But under the hood, they are fragile "Earth" creatures. The NvData is their heartbeat. Lose it, and you lose the phone. Back it up today—because in the world of MediaTek BROM, disaster is just one wrong click away.

For users of the Poco C55 or Redmi 12C (codenamed earth), encountering the "NvData is Corrupted" error can be a major hurdle, often leading to boot loops or "IMEI Null" issues. These files are critical for your device's network connectivity and hardware identity. Understanding NvData and NvRam
The NvRam (Non-Volatile Random Access Memory) and NvData partitions store essential, device-specific information, including: IMEI Numbers: Unique identifiers for mobile networks.
Baseband Information: Manages radio functions and cellular connectivity. Calibration Data: Wi-Fi, Bluetooth, and RF settings.
Because these files are unique to every single handset, flashing a generic firmware often doesn't restore them if they are lost or corrupted. How to Fix "NvData Corrupted" on Poco C55 / Redmi 12C

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.
On MediaTek chipsets (like the Helio G85 in the earth), the NVRam is a region of the flash memory that stores the factory calibration data. This includes:
