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.

The mention of "Redmi-12c-earth" refers to the specific platform code. In the Xiaomi/Poco ecosystem, devices sharing the "Earth" motherboard layout often have cross-compatible NvRam structures.
