Released in March 2022, the Xiaomi Redmi K50 Pro uses the Mediatek Dimensity 9000 platform and is known for its 108MP camera. If yours is stuck in a boot loop, laggy after an update, or locked, reinstalling the official Stock ROM is the safest way to restore performance and stability. This guide provides official firmware download links and a clear tutorial to flash with SP Flash Tool, including auth bypass notes where required.
Both scatter-based flash files and (where available) fastboot ROMs are included. Use the scatter package for SP Flash Tool and the fastboot package for Mi/brand-specific tools. Always match the exact variant/region to avoid compatibility issues.

How to Flash Xiaomi Redmi K50 Pro Firmware via SP Flash Tool
Step 1 — Prepare Your Workspace
- Install MTK USB & VCOM Drivers (reboot afterward if prompted).
- Extract the SP Flash Tool, Auth Bypass tool (if required), and the firmware package.
- Inside the firmware folder, locate the scatter file (e.g.,
MT6983_Android_scatter.txt).
Step 2 — Load the Firmware
- Right-click
flash_tool.exe→ Run as administrator. - Click Scatter-loading and select the scatter file.
- Set Download Only. Ensure preloader is checked for full unbrick (uncheck only if you know the risks).
Step 3 — (If Needed) Bypass Authentication
Newer MTK devices may enforce Download Agent authentication.
- Open MTK Meta Utility (or your preferred bypass tool) and select Disable Auth / Bypass SLA/DAA.
- Keep the bypass tool running while you begin the flash in SPFT.
Step 4 — Start Flashing & Connect the Phone
- In SP Flash Tool, click the green Download button.
- Power off the device completely.
- Connect the Xiaomi Redmi K50 Pro to the SP Flash Tool by:
- Hold Volume Up + Volume Down and plug in the USB
- Once detected, SPFT will sequence red → purple → yellow bars and begin flashing. Do not disconnect.
- Wait for the Download OK green check mark.
Step 5 — First Boot
Disconnect the phone and power it on. The first boot can take 5–10 minutes while the system optimizes apps. If stuck, boot to recovery, wipe data/factory reset, and then reboot.
Troubleshooting & Common SP Flash Tool Errors
- BROM ERROR: S_FT_ENABLE_DRAM_FAIL (4032) — Wrong or incompatible preloader. Re-download exact region/variant; keep preloader checked for hard-brick cases.
- BROM ERROR: S_AUTH_HANDLE_IS_NOT_READY — Use an auth-capable DA or enable Disable Auth in MTK Meta Utility, then retry.
- BROM ERROR: S_BROM_CMD_STARTCMD_FAIL — Try a different USB port/cable; reconnect with the correct key combo; reinstall drivers.
- Stuck at red bar — Driver handshake only. Ensure the bypass tool is active (if required) and that the scatter/DA matches the chipset.
- Bootloop after success — Enter recovery and perform a factory reset; if it persists, reflash with userdata and vbmeta included.
Frequently Asked Questions
- Do I need to unlock the bootloader for SP Flash Tool?
- Usually no. Scatter flashing with SPFT works at a low level; some models still require auth, which you can bypass with approved service tools.
- Can I flash without the preloader?
- For soft issues, you may uncheck preloader. For dead/brick states, flashing the correct preloader is often necessary. Using a mismatched preloader can hard-brick the device.
- Why does SP Flash Tool show BROM/S_AUTH errors?
- Newer MTK security enforces authentication. Use an auth-capable DA or an approved bypass workflow, and ensure drivers are correctly installed.
- Where can I get official builds?
- From the vendor’s OTA/CDN servers or trusted mirrors. Always verify the filename, device code name, and region.
