Mi Flash Error Cannot Find File Flashalllockbat [exclusive] May 2026

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

If using Mi Flash, it will show “success” and device will reboot.
If using fastboot: after relock, device should reboot; check bootloader state with:
```
fastboot getvar lock_state
```
or check device behavior on boot.

Missing/incorrect ROM type
- Cause: You downloaded a recovery ROM (flashable via Updater) or a packaged ZIP without fastboot scripts.
- Fix: Download the Fastboot ROM (file name usually contains "tgz" or "fastboot"), extract it; the folder must contain the .bat files.
Improper extraction / nested folders
- Cause: Some archives extract into a nested folder; Mi Flash pointed to the parent still lacking the .bat files.
- Fix: Open the extracted folder and ensure the path you select in Mi Flash contains flash_all_lock.bat directly (not inside another subfolder).
File renamed or removed
- Cause: User or extraction tool renamed/removed .bat files or OS hid extensions.
- Fix: Make sure extensions visible and file names exactly match; restore from a fresh ROM archive.
Using the wrong tool or version
- Cause: Using a recovery flasher or outdated Mi Flash that expects different structure.
- Fix: Install latest Mi Flash for Windows from Xiaomi site and retry.
Corrupted download
- Cause: Interrupted or corrupted ROM download missing files.
- Fix: Re-download and verify file size/hash if available.
Permissions / Antivirus interference
- Cause: Windows blocks .bat or prevents Mi Flash accessing folder.
- Fix: Run Mi Flash as Administrator; temporarily disable antivirus/real-time protection.
