What do you need

Before you start flashing your phone via Fastboot, you need to prepare a little:

Check that the phone is successful, install all the necessary drivers if this is not the case.
Install special MiFlash program, also called MIUI ROM Flashing (there will be a link throughout the article).
And, of course, you can’t do without it yourself. You need to select either or the version for firmware in Fastboot mode. Downloading should only happen from the MIUI website and only for your specific model! Required file extension – ".tgz". If you get caught ".gz"- just rename it.
Do not forget that for a successful operation we need an unlocked bootloader. Bootloader inactive? Then use this topic.

Step-by-step instructions on how to flash Xiaomi via Fastboot

Now let’s proceed directly to the firmware of the Xiaomi smartphone itself, which will take place via a computer. On the phone There should be at least 60-70% charge left.

Step 1: Install MiFlash and Drivers

Before installing the MIUI ROM Flashing Tool program on your PC or laptop, you had to disable digital driver signature verification, but this requirement is no longer relevant.

A quick note: this article uses MiFlash version 2017.04.25. The developer website xiaomiflash.com has a version dated 2018.11.15, but there are some problems with it. The new version also does not require installation or rebooting of the PC, it is portable and works right out of the box.

Step 2: Unlock Bootloader

Recently, unlocking the bootloader has been significantly simplified. There is no need to submit an application to the official Xiaomi service and wait several days for a positive decision, which, otherwise, might not have happened. Now users can immediately begin activating the bootloader. Let's describe the brief instructions:

The first and most important thing to do is to pair your phone with . The screenshots below show everything in detail.
Now just have to wait for 360 hours to pass and then you can continue.
After that we You will need one more utility, namely Mi Flash Unlock. You can find it on w3bsit3-dns.com or on the official Xiaomi website.
After that, open the program as administrator, put the device into Fastboot mode ( turn off the phone, wait about a minute and press the volume minus button with the power button) and connect to the computer. Reading of information will begin.
At the end of the procedure, three green dots should appear - a sign that Bootloader has been successfully unlocked. Made. Do not forget that on our website you can familiarize yourself with.

Step 3: Selecting the correct firmware

Now I pay special attention to choosing the right archive with firmware for your Xiaomi model. This article describes a method for flashing firmware via MiFlash. In the video below, I talked about the method without MiFlash, that is, through ADB Platform-tools.

Download firmware for MiFlash (any regular firmware file).
Download firmware for ADB Platform-tools (only for firmware in Fastboot mode).

Step 4: Put your phone in Fastboot mode and connect to your PC

When the preparation is complete, take the mobile device, turn it off and wait about a minute, so that all processes in the smartphone completely stop. Now we launch Fastboot mode on the phone.

This is done as follows: Hold down the power key and volume down rocker. We hold it until a hare with earflaps appears, repairing the Android. Now the device can be connected to the PC.

We connect the phone to the PC only after activating Fastboot mode, otherwise there will be an error!

Step 5: Launch Mi Flash program and flash Xiaomi firmware

Now a few important steps.

Let's unzip the archive with the firmware using any available archiver.
Transfer the files to the root of the system disk into the Flash folder (you need to create it). There should be no Russian letters along the path to the firmware files (example: C:\flash).

Next, launch the MiFlash shortcut from the desktop. Click on the button "Select" located in the upper left corner and indicate the path to the firmware. Confirm with "OK." We update the list of connected devices using the key "Refresh". We go down below, where we see the points:

Clean all – deletes all files from the device without the possibility of recovery;
Save user data– does not touch user data;
Clean all and lock – completely cleans your smartphone and...

Be extremely careful here! It is best to choose the first option so that nothing interferes with the process. Also required before starting the operation. Dump backup files to your computer, since the SD card also has the risk of being suddenly cleared during an incorrect flashing process.

We carry out the final action - click « Flash» . Flashing begins. You cannot disconnect your smartphone from your computer while in the field. « Result» the inscription will not appear « Success».

The procedure may take some time, and during this period any actions with the phone are strictly prohibited. At the end of the operation, the mobile device will reboot and start on the new version itself.

Possible problems

If the firmware is not installed or the phone simply does not start after the update, pay attention to the following possible reasons and solutions:

Damaged firmware file. The archive may have been downloaded from an unreliable source or unpacked incorrectly, watch our step-by-step video instructions. Download another version and be sure to disable your antivirus, otherwise it will remove the necessary elements.
During flashing, the phone was completely discharged. This happens if less than 30% of the charge remains at the beginning of the operation. Do not immediately connect your smartphone to charge if it has recently been reflashed. Here you need to disassemble the phone and remove the battery (in this case there is no way to disassemble it) and after 10-15 minutes insert it again. Try turning it on. Doesn't work? Then put it on charge and try again after half an hour.

As you can see, flashing a Xiaomi phone via Fastboot is quite possible. Yes, it takes a little time, responsibility and attention, but the result will definitely not disappoint you. To avoid any questions after reading the article, we recommend that you familiarize yourself with another method from the video.
