Today is the turn of friends who own one of the best mid-range ever made by Xiaomi: we are talking about RedMi Note 4 in its Snapdragon processor variant! Let's see today how to replace the floppy ROM with an official ROM using MiFlash and without unlocking the bootloader!
Topics of this article:
Let's see what we need and how to do it.
- download directly from your RedMi Note 4 the Global ROM (stable or developer) from the following link, by clicking on DONWLOAD FULL ROM: Download Section ROM RedMi Notes 4 SD (verify that you are in the "Redmi Note 4 Qualcomm Global" tab otherwise you will download ROMs for the MediaTek variant!)
- go to the app updater from your phone
- click on the 3 balls in the upper right and select "select update package"
- navigate to the path where you downloaded the ROM and click on the .zip of the ROM
- then follow the on-screen instructions to install the ROM
If, instead, the app updater reports an error in the package analysis, proceed with the installation of MIUI Global with the help below.
- perform all the operations with fully charged smartphones
- the connection to the PC must be done without the use of HUB USB
- the flash of the new ROM will result in the loss of all data: A backup on another device is strongly recommended
- the guide is also working to install other official ROMs, provided in fastboot version
- xiaomitoday.it assumes no responsibility for procedural errors
Disable driver signatures on your PC (required for Windows 10 and Windows 8.1)
- from the phone, go to settings -> device information and click 7 times on MIUI Version: in this way we will become developers
- always from the phone, now, let's go back to settings -> additional settings (the second item, not the one under "hotspot" but the one immediately following "memory") -> developer options and activate the Debug USB
Now let's turn off signatures on your PC.
- (if you have Windows 10 follow these steps and then proceed to the next step)notifications icon bottom right, click on all settings, then up upgrade and security, select the card for developers and choose the developer mode
- (if you have Windows 8.1) restart by holding down the SHIFT key and, at restart, enter the TROUBLESHOOTING menu and then in ADVANCED OPTIONS
- then click on START SETTINGS and then on RIAVVIA. When you reboot, you will be presented with one list like this below and you will have to click F7 by disable driver signatures. The PC will restart automatically
We install adb and MiFlash drivers on the PC
We just restarted the PC, then download the following files:
Download minimal driver installation files
Download MIUI Global Beta 7.3.9 Fastboot versionDownload MIUI Global Stable 8.1.15 Fastboot version
now connect the phone to the PC and verify that it is connected in MTP mode (lower the notification curve and, if connected in "charging" mode, change it to MTP). At this point on your phone you will see a message asking you to allow USB debugging from your PC: before agreeing to it, we will post the box "always allow debugging USB from this computer"And then we give our consent.
Now let's start the driver driver installation tool (right click + start as administrator) and proceed with the installation.
At the end we install MiFlash and when prompted to install the drivers with a warning, we consent to the installation of the drivers. The message will be repeated 5 times higher and we confirm it all the time.
We restart the PC. Let's go to C: \ Program Files (x86) \ Minimal ADB and Fastboot.
While holding down SHIFT, click the RIGHT mouse button in a white space of the folder and select "Open a Command Window Here" from the menu. The command window will open in which you will have to write WITHOUT VIRGOLETTE "adb devices".
If before the debug authorization message appeared on the display of your RedMi Note 4, be sure that it will appear now. So, before agreeing, we check the box "always allow debugging USB from this computer"And then we give our consent.
You will see an alphanumeric string next to the device writing. We can then move on.
We write without the quotation marks "adb reboot edl" and your phone will look dead, or the screen will turn black, but it will stay on. Everything in the standard.
Now we have to extract with WINRAR (only with WINRAR I recommend!) ROM from downloaded .tgz file.
You will have a new folder with a name similar to this: "mido_global_images_ecc etc" with a folder of images and other files inside it.
We then move the folder to C: / so as to have the following path: C: / mido_global_images_ecc etc /, even better if we rename the folder in C: / rom to shorten the path of the files (could cause an error).
How to flash ROM from MiFlash
start MiFlash, click on SELECT and select the downloaded ROM folder - point (1) of the image.
Click on REFRESH - point (2) - and a string will appear with code COM10 (3) We select clean all at the bottom of the program - point (4) - and let's wait for a few minutes to wait for a flash.
Click on FLASH (5) and wait for the process to complete.
When the program completes the operation, the phone will restart automatically (if it does not restart, hold down the power key and restart).
What to do now? Nothing, wait for the restart, and even if you are going to have a good deal of fun you can enjoy the full functionality of the ROM Global.
Flash problem resolution (can not read from this port)
If MiFlash gives you a similar error, the reasons may be:
- you extracted the ROM into a folder with spaces in the name or in a folder with the same name as the one in which it is contained (just move the ROM)
- you WINDOWS 7 and you have not disabled verification of driver signatures
(restart the PC: during Windows boot, press F8 and the screen below will appear Select FIRMA DRIVER SETUP DISABLED and the PC will restart Proceed with the flash from Miflash as a guide without reinstalling the drivers b) - NOTE: THE SETTING IS DISABLED UP TO YOU DO NOT REACH YOUR PC
I hope I have done what you like and I remind you that you will soon see other similar guides like this but for other Xiaomi devices. A good news no?

All written well and clear. Unfortunately when I click on developer options it tells me that the application has crashed… do you have any advice? Thanks 1000
