Crucial Warning: Flashing via flash_all.bat reformats internal UFS 2.2 flash storage, erasing all user documents, local media, and cryptographic tokens. Packages carrying the WPG identifier belong strictly to the spinel hardware platform and must never be cross-flashed onto 5G models such as the Redmi Note 15 5G (spring), as conflicting chipset architectures will result in an irrecoverable hard brick. When using Mi Flash Tool, NEVER select "clean all and lock" (flash_all_lock.bat) if you are flashing cross-regional firmware to prevent locking the bootloader against mismatched regional root-of-trust signatures.

Flashing Overview for Xiaomi Redmi Note 15 4G
- Unlock the phone bootloader using the official Xiaomi Mi Unlock utility.
- Extract the .tgz archive twice using 7-Zip until flash_all.bat and the images folder appear.
- Power off the phone and hold Volume Down + Power together until the orange FASTBOOT screen displays.
- Open Mi Flash Tool, select the extracted firmware root directory, and choose "clean all".
- Click "Flash" and keep the phone connected while sparse partitions stream into UFS 2.2 storage.
Expand preparation checklist for Xiaomi Redmi Note 15 4G
- Verify your phone codename is 'spinel' by executing 'fastboot getvar product' from a command line while in Fastboot mode.
- Unlock the bootloader using the official Xiaomi Mi Unlock utility before attempting Fastboot partition flashing.
- Install official MediaTek USB VCOM / Preloader drivers and updated Android SDK Platform Tools (v35+) on a 64-bit Windows PC.
- Ensure the 6,000 mAh battery holds at least 50% charge before beginning the flashing process to prevent shutdown during 8GB+ super partition streaming.
- Extract the .tgz archive twice using 7-Zip until flash_all.bat and the images directory appear in the root path.
- Connect the phone via a certified USB Type-C data cable directly to a rear motherboard USB port to avoid communication drops.
Compatibility & Bootloader Notes
Official Fastboot flashing requires an officially unlocked bootloader via the Xiaomi Mi Unlock utility. MediaTek Helio G100 Ultra BootROM (BROM) mode enforces secure hardware authentication; low-level scatter flashing via SP Flash Tool requires an authorized service account or MTK Auth Bypass.

Frequently Asked Questions
The Helio G100 Ultra (MT6789) is fabricated on TSMC's 6nm N6 process node. It utilizes an octa-core CPU layout: two Cortex-A76 performance cores clocked up to 2.2 GHz and six Cortex-A55 efficiency cores at 2.0 GHz, coupled with an Arm Mali-G57 MC2 GPU. The storage controller operates over high-speed dual-lane UFS 2.2, delivering sequential write throughput exceeding 500 MB/s. This bandwidth ensures that large sparse system and dynamic super partition chunks stream continuously during Fastboot flashing without causing buffer underruns or host transport timeouts.
On Android 16 with HyperOS 3.0, Xiaomi packages the core operating system read-only filesystems (system, system_ext, vendor, product, odm) inside a consolidated dynamic super container (super.img) that spans over 8 GB. When flashing with flash_all.bat, the fastboot client automatically commands the device to enter userspace fastbootd mode to write these sparse chunks sequentially. This dynamic design allows dynamic partition boundary adjustments without repartitioning the underlying UFS chip.
Although sharing the Redmi Note 15 marketing family name, these two models use completely incompatible processor and modem hardware: the Redmi Note 15 4G (spinel) is built on MediaTek's 6nm Helio G100 Ultra 4G LTE platform, whereas the Redmi Note 15 5G (spring) utilizes a Qualcomm Snapdragon 4 Gen 2 or MediaTek Dimensity 5G platform. Flashing firmware between spinel and spring will corrupt the primary partition table and trigger hardware bootROM cryptographic lockouts.
Under Google's Android 16 architecture on Linux 6.x kernels, the boot sequence separates generic core Android ramdisk assets from hardware-specific board drivers. The generic boot ramdisk resides inside init_boot.img, board-level MediaTek kernel modules and device tree binaries reside in vendor_boot.img, and the raw kernel binary is housed in boot.img. When performing manual partition restorations via command-line Fastboot, technicians must flash init_boot.img alongside boot.img to ensure system initialization succeeds.
