Mi Flash Error Cannot Find File Flashalllockbat Free May 2026

Troubleshooting: "mi flash error cannot find file flash_all_lock.bat"

Summary

This error occurs when Xiaomi Mi Flash (or a related fastboot flashing process) cannot locate the script file named flash_all_lock.bat (or flash_all_lock) required to relock the bootloader or flash a fastboot ROM. Causes include wrong ROM folder structure, incorrect ROM package type, incomplete/unzipped ROM, misnamed files, or using the wrong flashing tool/version.

1. Open the ROM folder manually in Windows Explorer.
2. Look for files named flashall.bat and flashall_lock.bat.
3. If they are missing, the download was likely corrupted. Re-download the ROM.

• Download the latest Mi Flash Tool (e.g., 2022.4.15.0 or newer).
• Install it (avoid Chinese version if possible; use English/global).

Cause 4: Folder Naming or Path Issues
