2. Custom modified versions from xiaomi.eu and miui.su. You can download the version from miui.su in .

In addition, in order to reflash a smartphone, you will need root rights (we discussed how to get them in a separate article), as well as a program for automatic flashing and TWRP Recovery.

Xiaomi Mi4 firmware: procedure

Flashing Xiaomi Mi 4 is quite simple. For comparison, with smartphones from HTC, you often need to fool your head much longer. With Xiaomi Mi4, the procedure is as follows:

1. Install custom recovery:

• Turn off the phone and start it in fastboot mode (at the same time hold down the power key + volume down button).
• Connect the computer to the phone via the original USB cable, run the necessary *.bat file, before unpacking the . The cwm.bat and twrp.bat files install the necessary recovery, and stock.bat will allow you to return to the phone's native recovery later. Follow the instructions written on the screen.
• Boot into the installed custom recovery by simultaneously pressing the power and volume up buttons.

1. Flash your smartphone after making a backup of all data: boot into custom recovery (in this case TWRP), select Install and find the firmware archive with .zip resolution you need to install. Attention! You may need to merge the two system partitions into one before this (in the case of Marshmallow firmware).

Also, in order to avoid errors during the firmware process, we recommend that you perform the following steps:

• In Recovery, select Wipe or "Advanced Wipe".
• Next mark Cache, Data», Dalvik/ART Cache, System, "Internal Storage"(the last action will delete all user data from the microSD memory card).
• Select "Advanced" — "Fix Contexts".

Sometimes, in order to fix an error that popped up as inopportunely as possible, you can fix it by renaming the firmware to miui.zip”, however it is best to follow the steps above.

While all the system files are being flashed, the phone cannot be disconnected from the PC and in general it is advisable not to touch it. After the operation is completed, the first switching on of the phone can take a long time - you should not be afraid. The process may take 15, 20 or even 30 minutes, and there may be several reboots during the phone startup - this is quite normal.

If you have easily coped with the previous points, this one will seem quite simple to you. You need to drop the archive onto the memory card, which we also flash through Recovery.

1. Launch MiFlash and press the button " Select» to indicate to the program the path containing the firmware files.

2. In the window that opens, select the folder with the unpacked firmware and press the button " OK».

3. We connect the smartphone, transferred to the appropriate mode, to the USB port and press the button " refresh". This button is used to identify the connected device in MiFlash.

4. At the bottom of the window is the firmware mode switch, select the desired one:

• « clean all"- firmware with preliminary cleaning of partitions from user data. It is considered ideal, but deletes all information from the smartphone;
• « save user data"- firmware with saving user data. The mode saves information in the smartphone's memory, but does not insure the user against errors during the operation of the software in the future. In general, applicable for installing updates;
• « clean all and lock"- complete cleaning of the smartphone's memory sections and locking the bootloader. In fact - bringing the device to " factory» condition.

5. Everything is ready to start the process of writing data to the device's memory. We press the button " flash».

6. Watch the progress bar fill up. The procedure can take up to 10-15 minutes.
