Redmi Note 12T Pro is a performance-focused midrange Xiaomi phone (China variant) built around a Dimensity 8100-class platform, so users mainly care about stable thermals, smooth UI, and reliable daily battery life.
Across recent HyperOS 2 / Android 15-era discussions, the most repeated “pain points” are overheating and faster battery drain after updates, plus occasional camera/app instability depending on the build and installed apps.
The OS2.0.214.0.VLHCNXM fastboot firmware below is the newest listed China (CNXM) build for codename pearl, intended for a clean reinstall that often helps when OTA upgrades leave behind performance bugs or thermal/battery regressions.

Older builds (FYI): If you specifically need an older fastboot build for troubleshooting (rare), official archives list earlier VLHCNXM fastboot versions like OS2.0.212.0 and OS2.0.210.0, but flashing older builds is generally not recommended unless a newer update introduced a confirmed regression for your exact usage/apps.
