The device battery should be charged to at least 50%, and USB disconnections during flashing should be avoided to reduce the risk of corruption or hard‑bricks.

The safest option is to match the ROM suffix (MIXM, EUXM, RUXM, IDXM, TRXM) in the installed build with the same suffix in the HyperOS 1.0 version number before downloading the Fastboot file.
Is OS1.0.25.0.THGMIXM confirmed as Redmi Note 12 Pro 4G Global HyperOS 1 (Android 13)?
MIUIROM lists “REDMI Note 12 Pro 4G – Global – HyperOS 1.0.25.0.THGMIXM – Android 13” and provides matching Recovery, Fastboot and OTA packages, confirming this build for sweet_k6a.
Can Redmi Note 10 Pro (sweet) use these sweet_k6a HyperOS 1 Fastboot ROMs?
No; HyperOS trackers distinguish Redmi Note 10 Pro (sweet) from Redmi Note 12 Pro 4G (sweet_k6a), and MIUIROM explicitly labels these Fastboot ROMs for REDMI Note 12 Pro 4G only.
Does flashing HyperOS 1 Fastboot ROM on Redmi Note 12 Pro 4G always wipe user data?
Fastboot flashing and flash_all.bat scripts are typically designed for clean installs and are documented in guides as data‑wiping procedures, so backups are essential.
Is Redmi Note 12 Pro 4G (sweet_k6a) officially listed for HyperOS 2 in trackers?
HyperOS and MIUIROM pages currently emphasize HyperOS 1 Android 13 for Redmi Note 12 Pro 4G, and comments on those pages confirm that official information about HyperOS 2 support is limited or uncertain.
