Thanks To xiaomi.en for this thread

Greeting MIUI Lovers and Redmi Note 4 (MTK) Users,





This guide can be used on LOCKED and unlocked Bootloaders!


Steps for Flashing/Unbrick Redmi Note 4 (MTK):


Please be noted I will not take any responsibility for anything happened to your device.
Important: - Before flashing it is advised to take the backup of data and make sure that your phone battery is charged enough.

Install drivers from folder MTK_Driver_Installer_.1352 ext using DriverInstaller.exe inside this folder as Administrator.


Download Official Fastboot ROM (China Dev, China Stable, Global - whatever you'd like) from here:

And extract it.


Download edited cust.img


cust_global.rar :

And overwrite original cust.img inside just extracted Official fasboot ROM, images' folder.

This image partition contains only Local info and local apps.


Run flash_tool.exe as Administrator.

After program starts for Download Agent, select this download agent (MTK_All_In_One.bin). You can find it on SP Flash Tool folder.

For Scatter file select MT6797_Android_scatter.txt from extracted ROM's images' folder.

After files loaded uncheck preloader (Optional) (I've flashed te phone with all checkboxes)






Now with phone powered Off, click Downloadbutton and hold the Volume down (-) and connect the USB cable to the phone.

Hold the Volume down until you see the Chip info in left bottom corner or wait for yellow line:







Now sit back and wait to be finnished:






Remove the cable and hold Power button until vibrate.

Wait up to 15min (dont panic) to finish the boot.



Congrats you have working phone with your desired ROM (China Dev, China Stable, Global).



Hope It helped people bricked their phones like me

I downloaded the EU ROM image, and it doesn't seem to have a cust.img file inside. It only has three cust.prop files and one cust_variant file. The China developer ROM doesn't have it either. Have I downloaded wrong ROMs?

Edit: Never mind. I just noticed that the EU ROM isn't a Fastboot version (there currently doesn't seem to be one). I'll try some other method.
