This solution allows you to establish the official version of the system well, and most importantly - it makes it possible to restore the devices inexply in the program plan for just a few simple steps.

Details The installation process of the OS installation using Miflash to the Xiaomi device is considered in the reference material below, within the framework of this article we will dwell only on one feature of the model under consideration. In general, we perform steps of instructions from the lesson and result in a device with the official MIUI selected when loading the type of package type.

And now about the possible nuance. In order to implement the standard OS installation procedure, you must connect the device in EDL mode (Emergency Download). In the desired mode, the device is defined in the "Device Manager" as "Qualcomm HS-USB QDLoader9008",

and in Miflash as "COM XX", where XX - device port number

The Redmi 3S model, especially in the case of "oxidizing", can provide its owner some difficulties with this issue. We try to translate the smartphone to the desired state.

Method 1: Standard

1. On the disabled, you clamp "Volume +", and then the "Power" button until the next screen appears:



2. In the menu that opens, click "Download".



3. The phone screen should go out - the device in EDL mode.

Method 2: FastBoot

In case of the inoperability of the standard method, due to the presence of the installed custom recovery or for other reasons, you can translate the Redmi 3S to the emergency mode using the FastBoot command.

1. We load and unpack the package with ADB and FastBoot, for example here.



2. We translate the smartphone to the "FastBoot" mode. To do this, you need to simultaneously hold the volume and "inclusion" key on the disabled key, hold them before the image of a hare repairing android on the screen, under which "FastBoot" will be inscription.



3. Connect the device to the USB port, and then start the commands window. To do this, clicking and holding on the "SHIFT" on the keyboard, click right-click on the free area in the directory. In the dropping list of actions, there is an "Open command window". Click on it with the left mouse button.



4. On the command line we write the following:

   FastBoot OEM EDL

   And press the "ENTER" key.



5. As a result, the phone will stop submitting signs of life (the screen will go out, it will not respond to the short pressing key), but the device is in "Download" and ready to work with Miflash.

Method 3: Cable with closed contact

If you switch to EDL mode by previous methods, it is impossible to resort to the next method implying some temporary "modification" of a USB cable that is used to connect the device to the PC.

The method requires accuracy and attentiveness! In case of user error when manipulation, it can lead to hardware damage to the smartphone and / or USB port!

The methodology of the method requires to connect the Redmi 3S briefly to the USB port using a cable in which the D + contact is closed on the plug housing.

1. We make a temporary jumper. You can take a piece of wire, but more preferable is the use of aluminum foil.

   

   Bending a future jumper in the form of a loop.



2. We dress the jumper on the cable plug so that the second contact to the left, if you look at the location of the plastic substrate at the bottom, was closed on the housing:



3. Connect the Micro-USB plug to the device turned off. Then neatly connect the cable with the jumper to the USB port of the computer.

   

   Additionally. If the device hung on the "Mi" screensaver or during the boot process, it cannot be turned off by a long press "Power" button, then before connecting the cable with a jumper to a PC, clamp and hold the inclusion key on the smartphone. The "Power" button is released as soon as the device screen goes out as a result of connecting a modified cable to the USB port.

4. We are waiting for 5-10 seconds, remove the cable with a jumper from the USB port of the PC, we remove the jumper and insert the cable to the place.
5. Smartphone is translated into download mode.

Additionally. Exit from the "FastBoot", "EDL", "Recovery" mode is carried out using a long (about 10 seconds) Pressing the Power Keys. If it does not work, you climb all three device hardware keys at the same time: "Volume +", "Volume-", "Enable" and hold them before rebooting the phone.

Method 4: QFIL

Another opportunity to flash Xiaomi Redmi 3S, as well as restore the "Okimpinged" device provides the Qualcomm Flash Image Loader utility (QFIL). This tool is part of the QPST software package developed by the creator of the hardware platform of the model under consideration.

The method involves the use of FastBoot firmware for Miflash, and also requires the transfer of the device to the EDL mode by one of the methods described above. You can download the program by reference:

Download QFIL for Xiaomi Redmi 3S Firmware

1. We download the FastBoot firmware from the Xiaomi official website and unpack the received package to a separate folder. When working with QFIL, the contents of the "Images" directory will be needed.



2. Install the QPST package, following the instructions of the installer.



3. Upon completion of the installation of the software package

   

   We open the folder on the way: C: \ Program Files (x86) \ Qualcomm \ Qpst \ Bin \

   then double click on the file Qfil.exe..

   

   Or we find the QFIL application in the Start menu of Windows (QPST section) and run it.



4. SELECT TYPE switch set to "Flat Build".



5. In the "ProgramMerpath" field you need to add a special file. Prog_emmc_firehose_8937_ddr.mbn. . Click "Browse", then select the file in the Explorer window and click the Open button.



6. After the previous action, click "LoadXML",

   

   What will allow alternately to add files:

   • Rawprogram0.xml.

   

   • Patch0.xml.



7. We connect Redmi 3S, pre-translated into the EDL mode, to the PC. Confirmation of the correct definition of the device program is the "Qualcomm HS-USB QDLoader9008" in the upper part of the window, as well as the "Download" button on a monophonic blue color.



8. We are convinced that all the fields are filled with both the screenshot above, and start transferring files to the device's memory sections by pressing "download".
9. The progress of recording files in the memory of the smartphone is accompanied by the appearance of various inscriptions in the "Status" field.



10. The manipulations conducted by QFIL occupy about 10 minutes and are completed by the messages "Download succeed", "Finish download" in the "Status" field.



11. Close the program, turn off the phone from the USB port and run a long press (about 10 seconds) the "Turning on" keys.
12. Initially, the device will boot into Recovery mode. Just we are waiting for 30-60 seconds before an automatic reboot (the appearance of the "Mi" logo), after which there will be a long initialization of the installed system components.



13. Completing the installation of the software can be considered the appearance of the MIUI greeting screen.

Method 5: FastBoot

To install OS in RedMI 3S via FastBoot, no Windows-utility is installed, so the method seems preferable when problems occur in the application of applications from the methods above. In addition, FastBoot may be the only effective method of recovery if the device is able to boot only in the FastBoot mode.

For installation in Redme 3S via FastBoot according to the instructions below, you will need only downloaded from the Xiaomi FastBoot firmware.

1. Unpack the package from the OS into a separate directory.
