Crucial Warning: Fastboot flashing via flash_all.bat completely reformats the internal eMMC 5.1 storage including user data and internal virtual SD card. Never select "clean all and lock" (flash_all_lock.bat) when flashing cross-regional packages (e.g. flashing Global or EEA software onto a Chinese domestic 22122RK93C board), as mismatching bootloader cryptographic region tokens will trigger an Anti-Rollback (ARB) brick.

Frequently Asked Questions
The MediaTek Helio G85 MT6769Z integrates an embedded eMMC 5.1 host controller running on high-speed HS400 bus timings. On Android 14 HyperOS packages, physical partitions are arranged using Android dynamic partitions. A single contiguous super.img partition spans approximately 4.5GB and encapsulates the logical blocks for system, vendor, system_ext, and product. When Mi Flash Tool executes flash_all.bat, the fastboot client creates a virtual linear device-mapper table on the eMMC chip before streaming the logical sub-images.
The European and Global NFC edition (model 22126RN91Y) features an integrated NXP PN557 near-field communication controller soldered to the motherboard upper RF sub-assembly with an antenna loop routed into the plastic rear housing. Standard models (22120RN86G and India 22120RN86I) omit this chip at the factory SMT level. While the same Fastboot ROM executes on both hardware revisions due to universal device-tree overlay (DTBO) probing, flashing non-EEA firmware may disable the NFC software daemon toggle in Settings.
Inside the uncompressed .tgz archive, the root directory houses the primary execution scripts: flash_all.bat (erases data and flashes all partitions), flash_all_except_data_storage.bat (preserves userdata), and flash_all_lock.bat (flashes and relocks the bootloader). Partition binaries (boot.img, dtbo.img, super.img, vbmeta.img, preloader_raw.bin) reside inside the /images/ subfolder. When specifying the ROM path in Mi Flash Tool, users must select the top-level parent folder containing the .bat scripts, not the /images/ directory.
Android 14 HyperOS utilizes updated File-Based Encryption (FBE v2) with hardware-backed Keystore keys tied to the MediaTek Trustonic Trusted Execution Environment (TEE). Older custom recoveries fail to decrypt the userdata partition, displaying scrambled filenames under /data/media/0. The twrp-12.1_3.7.0-v000-earth image incorporates updated key derivation libraries, but technicians migrating from official HyperOS to custom AOSP ROMs must execute a "Format Data" (typing "yes") to rebuild the ext4 cryptographic file system.
