In this guide, we will show you the steps to flash the MIUI Fastboot ROM on Xiaomi/Redmi/Poco devices via Mi Flash Tool. Some of you might ask why is there a need to manually flash a ROM when the OEM themselves rolls out OTA updates at regular intervals. Well, the update that Xiaomi rolls out is only suited for a particular ecosystem- which is a stock device with no system-level modifications, truth be told, this is sufficient to meet the demands of the majority.
However, for the tiny minority like us, aka the tech enthusiast, installing updates via the OTA might not be the best route. For example, if you are currently rooted, on a custom ROM, or your device is in a bootloop or softbrick state, then you wouldn’t be able to opt for the native method of installing the update. Instead, you will have to manually flash the firmware file. And this is where lies the benefits of this process.
So if you are currently using a custom ROM but want to go back to stock MIUI, then you could easily do so by flashing the Fastboot ROM on your Xiaomi/Redmi/Poco device via Mi Flash Tool. Likewise, if the device is currently in a soft-bricked state, then you wouldn’t be able to access the OS and the Fastboot Mode will be the only accessible mode.
That’s not a cause of concern either as you could directly flash the Fastboot ROM and bring your device back to life. Well, there could be a plethora of other reasons why you might want to take the manual route. So without any further ado, let’s show you this task could be carried out right away.

The below process will wipe off all the data from your device, so please take a complete device backup beforehand. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.
STEP 1: Install Android SDK Platform Tools
First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform tools folder, which will be used throughout this guide.
STEP 2: Unlock Bootloader
You will also have to unlock the bootloader on your device before you could flash the Fastboot ROM. Do note that doing so will reset your device and might nullify the warranty as well. So if that’s well and good, then do check out our guide on How to Unlock Bootloader on any Xiaomi/Poco/Redmi/Mi Device.
STEP 3: Download Mi Flash Tool
Next up, grab hold of the Mi Flash Tool from here. Once downloaded, extract it to any convenient location on your PC.
STEP 4: Download and Extract Fastboot ROM
You may now download the Fastboot ROM corresponding to your device from the official site or third-party site of your choice [such as Xiaomi Firmware Updater]. The firmware will be downloaded in TGZ format, so you will have to extract like using an archive utility app like 7ZIP. Here’s how it could be done:
- To begin with, download and install the 7ZIP software on your PC.
- Then right-click on the Fastboot ROM TGZ file and select Open With> 7-ZIP File Manager.
- Once the extraction is complete, you will get another file in TAR format.
- So right-click on the TAR file and select 7ZIP > Extract Here.
- You will now get all the extracted firmware files, with the partition files present in the Images folder.
STEP 5: Boot Device to Fastboot Mode
If your device is currently in a bricked or bootloop state, then you could only boot the device to Fastboot Mode via hardware key combinations. On the other hand, if your device is working well and good, then you could also use the ADB commands to get this job done, apart from the hardware key combinations. we have listed both these methods below, refer to the one which is in sync with your requirement.
Via Hardware Kye Combinations
To begin with, power off your device. Then press and hold the Power and Volume down keys for a few seconds and your device will subsequently boot to the Fastboot Mode.
Via ADB Commands
- Head over to Settings > About Phone > Tap on Build Number 7 Times. This will enable Developer options.
- So go to Settings > Additional Settings > Developer Options and enable USB Debugging.
- Now connect your device to the PC via a USB cable.
- Then head over to the platform-tools folder, type in CMD in the address bar, and hit Enter. This will launch the Command Prompt.
- After that, type in the following command in the CMD window to boot your device to Fastboot Mode
adb reboot bootloader
STEP 6: Verify Fastboot Mode
Now that your device is now booted to the Fastboot Mode, let’s verify if your PC is able to identify the device in this mode or not.
- Type in the below command in the CMD window which is opened in the platform-tools folder.
- If you are getting a device ID [see above image], then you are good to go ahead.
- However, if you are not getting any serial ID, then install the Fastboot Drivers on your PC.
STEP 7: Install Xiaomi USB Drivers [If needed]
In most cases, the Xiaom drivers are automatically installed the first time you connect your device to your PC. However, let’s manually install them to be on the safer side. So launch the Mi Flash Tool via the XiaoMiFlash.exe file. Then go to the Driver tab and click Install. That’s it.
STEP 8: Install MIUI Fastboot ROM via Mi Flash Tool
- Launch Mi Flash Tool and click on Refresh. Make sure that your device ID is shown under the device section.
- If that’s well and good, then click on Select, browse to the extracted Fastboot ROM [the entire folder, not just the images folder], and click OK.
- At the bottom right is the flashing mode with three different options, namely:
clean all: It will reset your device but the device's bootloader will remain unlocked. save user data: It will preserve the data and the device's bootloader will remain unlocked. clean all and lock: it will reset your device and lock the device's bootloader as well.
- It is highly recommended that you opt for Clean all [see FAQ 1 for reasoning].
- Now that we have checkmarked all the prerequisites, you could hit the Flash button.
- The flashing will now start. Once done, your device will automatically boot to the OS. [see FAQ 2 if you get an error].
FAQ 1: Clean All vs Clean All and Lock
We have selected “Clean All” as it is the safest approach. If everything works well and good and your device boots to the OS, then you could easily lock the bootloader later on [if needed]. But if you relock it right now and something goes wrong during the flashing, then it could spell out trouble for you.
Therefore, it is always recommended to select “Clean All”. If we talk about “save user data”, then more often than not, it prevents the booting of the device due to encryption of the device or corrupt data. So it’s best to take a backup beforehand and select “Clean All”.
FAQ 2: Fix error:Not catch checkpoint (\$fastboot -s .*lock), flash is not done
Once the flashing is done, Mi Flash Tool might display the “error:Not catch checkpoint (\$fastboot -s .*lock), flash is not done”. It’s not a cause for concern and the flashing has infact been successfully completed. But still, if you want to know the detailed reasoning behind it and the steps to rectify it, then do check out our guide.
