Crucial Warning: Fastboot flashing via flash_all.bat formats internal UFS 4.1 flash storage, permanently erasing all user data, cryptographic tokens, and system settings. Always perform an off-device backup prior to flashing. Never choose "clean all and lock" (flash_all_lock.bat) when flashing modified images or cross-regional packages on the Dimensity 9400+ platform, as cryptographic signature mismatches against the hardware root-of-trust will trigger an immediate permanent bootloader lock brick.

Flashing Overview for Xiaomi Redmi K80 Ultra
- Download and extract the 10.13 GB TGZ archive twice with 7-Zip to C:\dali_fw
- Install MediaTek USB VCOM and updated Xiaomi ADB Fastboot drivers on your PC
- Power off phone, hold Volume Down + Power for 8 seconds until the orange FASTBOOT graphic appears
- Open Mi Flash Tool, set folder path to C:\dali_fw, and select "clean all" (flash_all.bat)
- Connect Type-C cable to PC rear port, click Refresh to detect device, and click Flash
Expand preparation checklist for Xiaomi Redmi K80 Ultra
- Verify model identifier 25060RK16C under Settings -> About Phone or rear regulatory laser markings
- Ensure the 7410 mAh silicon-carbon battery holds at least 50% charge to maintain bus power during the 10.13 GB partition write
- Keep the phone resting flat on your workbench to allow thermal dissipation during sustained high-speed UFS 4.1 writes
- Connect a certified 5A/6A USB Type-C data sync cable directly to a high-speed rear PC motherboard port
- Confirm bootloader unlock status through Settings -> Additional Settings -> Developer Options -> Mi Unlock Status
- Extract the 10.13 GB .tgz archive twice using 7-Zip directly to a root folder (e.g. C:dali_fw) to avoid Windows MAX_PATH command line truncation
- Install official MediaTek Preloader USB drivers alongside current Xiaomi Fastboot drivers on a 64-bit Windows PC
Compatibility & Bootloader Notes
Bootloader must be officially unlocked via Xiaomi Mi Unlock Tool before flashing fastboot TGZ packages.

Frequently Asked Questions
The Dimensity 9400+ (MT6991) platform pairs its Cortex-X925 and Cortex-X4 All-Big-Core CPU design with dual-channel UFS 4.1 high-throughput storage. Under Android 16 HyperOS 3.0, the partition table organizes essential boot components into Virtual A/B slots (boot_a/boot_b, init_boot_a/init_boot_b, vendor_boot_a/vendor_boot_b) while consolidating system, product, system_ext, and vendor partitions into an expandable dynamic super container (super.img). Cryptographic verification is enforced by MediaTek Hardware Root-of-Trust (HROT) with secure keys anchored in RPMB hardware blocks.
Xiaomi's 7-character build tag breaks down into precise platform identifiers: the first letter "W" strictly designates the underlying Google Android 16.0 base release (progressing from U for Android 14 and V for Android 15). The subsequent "ON" is the internal hardware board code for the dali platform, "CN" identifies the China mainland regional firmware branch, and "XM" indicates unbranded retail channel distribution. This taxonomy clearly separates the core Google Android 16 operating system base from Xiaomi's HyperOS 3.0 visual interface.
The Redmi K80 Ultra features an advanced 6.83-inch 144Hz OLED panel supporting 3840Hz high-frequency PWM dimming. Display timing profiles, gamma matrices, and low-brightness PWM drive parameters are loaded during early boot from the dtbo.img (Device Tree Blob Overlay) and vendor_boot.img partitions. Executing the complete official flash_all.bat batch script ensures that both the display driver IC (DDIC) firmware and the ARM Immortalis-G925 display processing unit (DPU) drivers synchronize without color cast or refresh rate flicker.
Fastboot protocol limits individual chunk transfer sizes according to available RAM during early bootloader initialization (max-download-size). Because the uncompressed dynamic super partition on the Redmi K80 Ultra exceeds 8.5 GB, the flash_all.bat deployment script slices super.img into sequential sparse segments (super.1, super.2, etc.). Mi Flash Tool streams these segments in order across the USB bus, and the device bootloader reassembles and writes them into physical UFS 4.1 blocks before calculating final SHA-256 partition integrity.
