Download the exact stock ROM for your device model number (e.g., Xiaomi Redmi 9C, model M2006C3MG). Do not use a ROM from a different RAM variant (2GB vs 4GB models use different DRAM initialization).

Do not try random firmware. Follow this order:

Step 2: Use a Signed/Custom DA

Step 3: The "RAM Test" Exclusion

Step 4: Bypass SLA/DAA (For newer Dimensity chips) Step 2: Use a Signed/Custom DA

Reinstall drivers – Ensure MediaTek USB VCOM drivers are properly installed, and no other software is interfering (like ModemManager on Linux).

Test with different version – Use an older or newer release of SP Flash Tool (e.g., v5.x vs v6.x).

Check hardware – Try flashing another device with the same setup; if it works, your original device may have a RAM hardware fault.

If you previously flashed a wrong preloader.bin from a different firmware version, the phone is trying to initialize RAM with the wrong timing parameters (CAS latency, frequency).

To fix this error, you must first understand what it means at the chipset level.

Generic patched DA files often cause this error. You need a DA that is: Step 3: The "RAM Test" Exclusion
