About the Redmi Note 15 Pro 4G
The Redmi Note 15 Pro 4G (codename: charoite) is Redmi's January 2026 mid-range Android smartphone, announced on December 18, 2025 and released on January 6, 2026, powered by the MediaTek Helio G200 Ultra (6 nm) chipset. It ships in a single hardware configuration — model 25100RA69G — sold across Global, EEA, and Turkey markets, each running a distinct HyperOS 2 firmware branch.
Each market's firmware carries a unique HyperOS 2 branch suffix (VPFMIXM for Global, VPFEUXM for EEA, VPFTRXM for Turkey) that determines system features, bundled apps, and OTA update eligibility. The Firmware Package section below explains how to identify your device's branch and select the correct Fastboot ROM before flashing.
Which Flash Mode Should You Use?
Mi Flash Tool (Fastboot ROM)
The standard method for the Redmi Note 15 Pro 4G. Despite running a MediaTek chipset, Xiaomi distributes charoite firmware as Fastboot ROMs — not SP Flash Tool scatter archives. Mi Flash Tool provides a GUI over the standard Android Fastboot interface and auto-executes the flash_all.bat script, writing all partitions in a single automated pass. Requires a prior bootloader unlock and erases all user data.
Manual ADB / Fastboot Commands
Advanced users can bypass the Mi Flash Tool GUI and flash individual partitions directly using the fastboot binary from Android SDK Platform Tools. This approach requires knowing each partition name and the correct flashing sequence. It is useful for targeted partition repairs — for example, flashing only the radio image — without reinstalling the full firmware, but is not recommended for complete system restoration on the Redmi Note 15 Pro 4G.
MediaTek BROM / SP Flash Tool (Emergency)
The Helio G200 Ultra supports MediaTek BROM (Boot ROM) mode — a hardware-level emergency interface accessible by holding Volume Down while connecting via USB-C to a PC running SP Flash Tool, even when the device is completely unresponsive. Unlike Qualcomm EDL, BROM does not require proprietary programmer files. However, Xiaomi does not publicly distribute the charoite scatter file required by SP Flash Tool, limiting BROM recovery to Xiaomi authorised service centres.
What You Need Before Flashing
Mi Flash Tool is Windows-only in its GUI mode. Download Mi Flash Tool (v20.2.0 or newer) and the Xiaomi USB driver package from the official Xiaomi developer portal and install both. On Linux or Mac, the flash_all.sh script from the extracted Fastboot ROM can be run directly using Android SDK Platform Tools, but Mi Flash Tool itself is not available on those platforms.
Fastboot flashing requires a previously unlocked bootloader. In Developer Options, enable OEM Unlocking and bind your Mi Account under Unlock Status. Download Mi Unlock Tool on a Windows PC and sign in with the same account. Xiaomi enforces a mandatory waiting period — typically 72 hours for established accounts, up to 168 hours for newer ones — before the unlock is granted server-side.
Download the Fastboot ROM matching your firmware branch. Check Settings → About Phone → OS version for the branch suffix (VPFMIXM = Global; VPFEUXM = EEA; VPFTRXM = Turkey). The model number 25100RA69G appears on the box and in the SIM tray for all three regions. Decompress the .tgz archive fully to a folder with no spaces in the path before running Mi Flash Tool.
A data-capable USB-C cable is required — charge-only cables do not carry the Fastboot protocol. The Redmi Note 15 Pro 4G uses USB-C 2.0; any data-rated USB-C cable from a reputable manufacturer will work. Connect directly to a USB port on your PC rather than a hub or extension cable for the most stable connection.
The flash_all script writes multiple large partitions over 5–12 minutes. The Redmi Note 15 Pro 4G's 6500mAh battery is sealed — it cannot be removed if it drains mid-flash. Ensure at least 30% charge before starting and keep the USB cable connected throughout the flash session. The 45W wired charging can bring the battery to a safe level in approximately 15–20 minutes.
Both the bootloader unlock and Mi Flash Tool's "Clean all" mode erase all user data. Unlike devices with no expansion slot, the Redmi Note 15 Pro 4G supports microSDXC — transfer photos and important files to a microSD card before unlocking or flashing, as the card is not erased by the process. Also back up contacts to Google Contacts and app data to a PC or cloud service.

Finding the Firmware Package for charoite
The Redmi Note 15 Pro 4G firmware is distributed by Xiaomi as a compressed Fastboot ROM archive (.tgz). After fully extracting the archive, locate:
flash_all.bat
This script is inside the extracted Fastboot ROM folder. After decompressing the .tgz archive (decompress twice if needed — once for the outer .tgz, once for the inner .tar), locate flash_all.bat (Windows) or flash_all.sh (Linux/Mac) at the top level of the resulting folder, alongside an images/ subdirectory. Do not attempt to run the script from inside a compressed archive — extract fully to a local folder before proceeding.
The Redmi Note 15 Pro 4G (codename: charoite) is released in a single hardware configuration — model number 25100RA69G — across Global, EEA, and Turkey markets. All three regions use the same physical hardware but carry different HyperOS 2 firmware branches. The branch suffix in the OS build string identifies your firmware: VPFMIXM (Global), VPFEUXM (EEA/Europe), VPFTRXM (Turkey). Downloading a Fastboot ROM from the wrong branch does not permanently brick the device but will break OTA update eligibility and may disable region-specific system features — always match the firmware branch to the one the device shipped with.
After decompressing the .tgz archive, you will find flash_all.bat (Windows) and flash_all.sh (Linux/Mac) at the top level alongside an images/ subdirectory containing individual .img files for each partition. Do not attempt to run the flash script from inside a compressed archive — decompress fully to a folder path that contains no spaces or non-ASCII characters before executing.
Note: Do not confuse the Redmi Note 15 Pro 4G (charoite) with the Redmi Note 15 Pro 5G (different chipset and codename), the Redmi Note 15 (standard non-Pro variant with lower camera specs), or the Redmi Note 15 Pro+ which features additional hardware. Firmware packages for those models are not compatible with the charoite hardware and must not be used.

Redmi Note 15 Pro 4G — Important Notes
The Redmi Note 15 Pro 4G is Redmi's January 2026 mid-range release, announced December 18, 2025 and available globally from January 6, 2026. Its standout hardware feature is the 200MP primary camera with optical image stabilisation — a sensor resolution more typically found on flagship-tier devices. The 6.77-inch AMOLED display features 3840Hz PWM dimming designed to reduce eye strain at low brightness levels, alongside Gorilla Glass Victus 2 protection both on the screen and the frame. The rear uses a plastic back construction, which contributes to the device's IP65-rated dust and water resistance without the weight of a glass back.
The 6500mAh silicon-carbon (Si/C) battery supports 45W wired charging and 18W reverse wired charging — the latter allows the Redmi Note 15 Pro 4G to charge other devices acting as a power bank. Because the battery is sealed, it cannot be removed if it drains during a long flash session. Ensure at least 30% charge before starting Mi Flash Tool, and keep the USB cable connected throughout. The 45W wired charging can bring the battery from near-empty to a safe flashing level in under 20 minutes. The shared SIM + microSD tray means users choosing to use two SIM cards cannot simultaneously use a microSD card — plan storage expansion accordingly before filling the device's internal storage.
Common Errors on the Redmi Note 15 Pro 4G
"waiting for device" — Mi Flash Tool or fastboot does not detect the phone
Mi Flash Tool cannot communicate with the Redmi Note 15 Pro 4G in Fastboot mode. On Windows, open Device Manager and confirm that "Android Bootloader Interface" appears when the phone is connected in Fastboot mode — an Unknown Device entry indicates the Xiaomi USB drivers are not correctly installed. Use a USB-C data cable capable of data transfer; charge-only cables will not carry the Fastboot protocol. Try a USB 2.0 port directly on the PC motherboard rather than a USB hub or front-panel connector. Verify the phone screen shows the Mi bootloader / Fastboot logo — a blank screen or the HyperOS lock screen means Fastboot mode was not successfully entered. Hold Volume Down + Power for 8 seconds to retry.
"auth failed" or "token mismatch" — bootloader lock prevents flashing
Mi Flash Tool returns an auth or token error when the Redmi Note 15 Pro 4G bootloader is still locked. The Fastboot interface on the charoite hardware rejects all partition write commands when the lock state is active. Complete the official bootloader unlock process through Mi Unlock Tool, ensuring the full mandatory waiting period has elapsed after binding your Mi Account. After unlocking, re-enter Fastboot mode and retry the flash session in Mi Flash Tool. There is no workaround for this error without going through the official unlock procedure.
"Flash failed" — firmware branch or device mismatch
Mi Flash Tool flashes some partitions but the device fails to boot, or the tool returns a flash failed error mid-process. The most common cause is downloading the wrong HyperOS 2 branch (e.g., VPFEUXM EEA firmware on a VPFMIXM Global device) or firmware intended for a different Redmi model. Verify your branch code in Settings → About Phone → OS version, or check the model number 25100RA69G on the device box, then download and flash the precisely matching Fastboot ROM. Do not use firmware packages labelled for the Redmi Note 15 Pro 5G, the Redmi Note 15 (standard non-Pro), or any other charoite variant not matching your region.
"send-data failed" — USB transfer error during flashing
The flash session begins but stops partway through with a send-data or data transfer error. This is almost always caused by a faulty USB cable or an unstable port. Replace the USB-C cable with a data-rated cable from a reputable manufacturer — charge-only cables cannot sustain the bulk transfer speeds required for partition flashing. Connect directly to a USB port on the PC motherboard rather than a USB hub or extension cable. Disable USB selective suspend in Windows Power Options before starting the flash. If the error consistently occurs at the same partition, re-download the .tgz archive and fully re-extract it, as a corrupted or partially extracted image will cause repeated transfer failures.
Device stuck on Redmi or HyperOS logo after flashing
A bootloop or a hang at the Redmi splash screen after flashing indicates that one or more partitions — most commonly the super partition sub-images or init_boot — were not fully written during the flash session. Re-enter Fastboot mode by holding Volume Down + Power for 10 seconds until the Mi bootloader screen reappears. Open Mi Flash Tool, re-select the extracted firmware folder, choose "Clean all" (not "Save user data"), and reflash from the beginning. If the device no longer responds to the Volume Down + Power combination, connect it to a PC and attempt fastboot reboot-bootloader via Android SDK Platform Tools. Devices that cannot reach Fastboot after a complete reflash require Xiaomi service centre intervention.

Frequently Asked Questions — Redmi Note 15 Pro 4G
Yes — without exception. Even though the Redmi Note 15 Pro 4G runs a MediaTek Helio G200 Ultra chipset, Xiaomi locks the Fastboot bootloader at the factory and Mi Flash Tool will reject partition writes with an authentication error if the lock state is active. This is distinct from some other MediaTek phones where SP Flash Tool can reach the device through the hardware BROM interface without any prior unlock. On the Redmi Note 15 Pro 4G, the standard firmware restoration path is Mi Flash Tool over Fastboot, which unconditionally requires an officially unlocked bootloader obtained through Mi Unlock Tool.
The bootloader unlock step wipes all user data immediately upon approval. Subsequently, selecting "Clean all" in Mi Flash Tool erases all partitions including userdata and cache, returning the device to factory condition. The "Save user data" option skips the userdata and cache partitions in an attempt to preserve personal files, but this mode is unreliable when firmware corruption extends into system partitions and may still result in data loss. Unlike devices with no expansion slot, the Redmi Note 15 Pro 4G supports microSDXC — transfer photos and important files to a microSD card before starting, as the card is not erased by the flash process. Also back up contacts to Google Contacts and app data to a PC or cloud drive.
Navigate to Settings → About Phone → All Specs → OS version. The build tag appended to the version string identifies your branch: VPFMIXM indicates the Global firmware (model 25100RA69G), VPFEUXM indicates EEA (European Economic Area), and VPFTRXM indicates Turkey. If the phone will not boot, the model number on the box or inside the SIM card tray will confirm the hardware variant — 25100RA69G covers all three of these firmware branches. Always download the Fastboot ROM that precisely matches your firmware branch; cross-branch flashing does not immediately brick the device but breaks OTA update eligibility and can disable region-specific system features.
No — not for standard firmware restoration. Xiaomi distributes HyperOS 2 firmware for the Redmi Note 15 Pro 4G as Fastboot ROMs, not as MediaTek scatter-file archives. The charoite firmware package contains flash_all.bat and individual .img partition files — a format designed for Mi Flash Tool and the Fastboot protocol, not for SP Flash Tool's scatter-file loading method. SP Flash Tool operates through the MediaTek BROM interface at a hardware level and requires the charoite scatter file, which Xiaomi does not publicly release. Use Mi Flash Tool with the official Fastboot ROM for all standard flashing and firmware recovery operations.
The MediaTek Helio G200 Ultra includes hardware BROM (Boot ROM) mode — MediaTek's emergency low-level interface, analogous to Qualcomm's EDL but more accessible: BROM mode is entered by holding Volume Down while connecting the device via USB-C to a PC running SP Flash Tool, and does not inherently require proprietary programmer files the way Qualcomm EDL does. However, SP Flash Tool must have the charoite scatter file to map the device's storage layout before it can flash anything — and Xiaomi does not publicly distribute this scatter file. Without it, SP Flash Tool cannot initialise flashing even with the device in BROM mode. Emergency BROM recovery on the Redmi Note 15 Pro 4G is therefore limited to Xiaomi authorised service centres.
