Behind Mi Flash XBL Error
There are many things known as the trigger of such problem on Mi Flash:
- Downloaded a wrong incompatible ROM file.
- The bootloader is still locked.
- A fake MIUI ROM was used previously.
- The ROM file is corrupt due to either improper decompressing or corrupted download.
- Trying to downgrade an ARB-enabled device: such as Redmi Note 5, Mi 8, and Mi 6X.
Try one of the following solutions to solve the Mi Flash Tool XBL Error:
- Double-check the ROM file you have downloaded. Make sure it is the correct build of the MIUI released specifically for your phone variant. How to check it? Each release of Fastboot ROM has the device codename within its file name. Check your device codename (find out here) and check the filename again. For instance, Redmi Note 5 Global/Pro has a codename Whyred. The ROM .tgz file should also have whyred as the component of the filename. You may need to download the file again if you found it is different.
- Unpack/decompress the ROM file again. Assuming you have the proper ROM file for your device. Trying to decompress/unpack the tgz file again may sometimes help you. There is a situation when a decompressing process partially completed.
- Make sure your bootloader has been unlocked. Flashing through a Fastboot interface using Mi Flash tool requires the phone bootloader being unlocked officially. Read our previous guide on how to get it done as pie.
- The bootloader is unlocked but you are on a fake ROM. This is the trickiest yet the easiest to solve even after switching back from a custom ROM. Thanks to Xiaomitool, an easy-to-use software to conveniently flash any MIUI ROM. Switching between ROM variants would be easy.
- If you are trying to flash an MIUI ROM on ARB-enabled devices, please make sure that you have double-checked the ARB Index of the ROM you are going to flash. Make sure it has similar or lower version of ARB index. Otherwise, it will fail for sure.
- Make sure the folder of where you have extracted the ROM files is inside a folder if the root directory.
- Old Xiaomi devices, such as Redmi 3S and Redmi 4/4X/4A, try using any older versions of Mi Flash tool. Employing a version released in the same year as device release year is recommended.
There are also some general workarounds you may also try. These are not specific to XBL Error but usually works on general Mi Flash error:
- Try using different USB data cable. Make sure it is a data cable and not a charging-only cable.
- Use different USB port in your computer. While USB 3.0 may work, USB 2.0 is more standard.
- Also, try installing the latest version of Android Platform Tools. Hence, your computer will have the updated version of ADB and Fastboot drivers.
- Try reinstalling Mi Flash tool using this sequence: uninstall the tool > disable Driver Signature Enforcement > reinstall the tool.
None of those work? There is still the ultimate solution to help you accomplish your purpose which is installing the version of MIUI ROM you want.
Scenario #1: If you have access to the bootloader/fastboot mode.
- Unlock your phone bootloader.
- Download the version of MIUI Recovery ROM (zip) you wish to install. Make sure it is the appropriate version for your device.
- Transfer the zip file to your phone.
- Download TWRP image file depending on your device type.
- ARB-enabled device needs to download Anti-rollback Bypasser.
- Download Magisk if you want to root, or use Lazyflasher if you don’t want a root.
- Flash TWRP on your device. ARB devices can follow the same sequence of Redmi Note 5 here that requires to flash Bypasser first.
- Flash Magisk or Lazyflasher. You need to do this to avoid bootloop.
- Flash MIUI Recovery ROM through TWRP.
Scenario #2: Without access to Fastboot mode.
This is the trickiest one.
- Reboot your phone to EDL Mode or Test-point Mode.
- Flash MIUI fastboot ROM (tgz) again through Mi Flash tool.
- Alternatively, you can flash the ROM file through Qualcomm Flashing Tool.
It may sound simple but rebooting to EDL mode using the Test-Point method is not a piece of cake.
