Incomplete downloads or improperly extracted firmware files can cause Fastboot commands to stall.
: Move from a front-facing USB 2.0 port to a rear USB 3.0 port on your PC, as front ports often lack stable power or data transmission. Always use the original or a high-quality USB data cable.
The tool detects the device, but communication fails at a fundamental level, leading to an eventual timeout. This error commonly occurs in EDL (Emergency Download) mode and can be persistent.
: Front USB ports on PC cases often lack stable power delivery, leading to mid-flash disconnects. Detailed Troubleshooting Steps Switch Physical Connections
Using a generic charging cable instead of a high-quality data cable.
Alternatively, manually check your to ensure your phone is recognized as "Android Bootloader Interface" without any warning icons. 4. Use the Command Line (Bypass the Tool)
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "osvc" /t REG_BINARY /d "0000" /f reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "SkipContainerIdQuery" /t REG_BINARY /d "01" /f reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "SkipBOSDescriptorQuery" /t REG_BINARY /d "01" /f Use code with caution.
Then, after a few seconds of hope, it stops. The log reads:
| Cause | Explanation | |-------|-------------| | | Unstable data transfer due to loose port, damaged cable, or USB hub. | | Wrong USB port type | USB 3.0 ports (blue) often cause EDL timeouts; USB 2.0 (black) is more reliable. | | Driver issues | Incorrect, missing, or conflicting Qualcomm/Mediatek drivers. | | Device authentication | Newer Xiaomi devices require Auth Bypass for EDL flashing. Without it, the device rejects commands → timeout. | | Corrupt ROM/image | Incomplete or mismatched ROM files (e.g., different region, older anti-rollback). | | Battery level | Battery below 30% can cause timeouts during write operations. | | Firewall/Antivirus | Interrupts Mi Flash Tool’s COM port communication. |
