[Tips & Guides] [MIUI with Tom #22] How You Can Check ARB Version MIUI ROM before Downgrade!

Hello MIUI Fans!

Today i'll show you how check ARB Version before downgrade your current ROM via MI FLASH! I want to show this to those who suddenly want to roll back the ROM to an earlier one, and not to look on the Internet for which version of the ARB is present in the ROM that will be rolled back, I will show how this can be checked and not be afraid that the smartphone will be broken after the rollback .

Number ARB is: 0, 1, 2, 3 = NO ARB!
Number ARB 4 is: Present! Don't try downgrade to ARB 1.2.3.0 - you device will be bricked.

For example i download 5 Fastboot MIUI ROM for different devices: MI MAX 3 = 3 ROM, MI9T = 1 ROM, MI 10 = 1 ROM!

First device is MI MAX 3:
Unzip rom and open folder with ROM, find file flash_all.bat and open it with Notepad++ or Notepad and check.

I use 3 different ROM Version: 9.6.6.0, 10.0.1.0, 11.0.2.0 latest


9.6.6.0 Android 8.1 How to Check ARB!
In file Flash_all.bat must be line with


set CURENT_ANTI_VER=


But in 9.6.6.0 no such line, that mean NO ARB and from this Version you can downgrade to the lower MIUI Version

10.0.1.0 Android 8.1

set CURENT_ANTI_VER=4

10.0.1.0 line is here and number is 4, that mean  ARB 4 and from this Version you can't downgrade to the lower MIUI Version. Downgrade available only to the SAME ROM WITH ARB VERSION = 4, Downgrade to 9.6.6.0 Brick your device.

11.0.2.0 Android Q


set CURENT_ANTI_VER=4

11.0.2.0 line is here and number is 4, that mean  ARB 4 and from this Version you can downgrade to the lower MIUI Version. Downgrade available only to the SAME ARB VERSION = 4. Downgrade to version 10.0.1.0 Available, to version 9.6.6.0 brick device.

MI 10 Latest MIUI 11.0.2.0

set CURENT_ANTI_VER=0

11.0.2.0 line is here but number is 0, that mean  ARB 0 and from this Version you can downgrade to the lower MIUI Version..
Also you can check file ANTI_VERSION.txt in IMAGE Folder


MI 9T Latest MIUI 11.0.5.0

set CURENT_ANTI_VER=0

11.0.5.0 line is here but number is 0, that mean  ARB 0 and from this Version you can downgrade to the lower MIUI Version..
Also you can check file ANTI_VERSION.txt in IMAGE Folder

I Check ARB on MI 9T on latest ROM and here the screenshot:


I use command in CMD:
fastboot getvar anti

That mean i can downgrade to the lower MIUI Version!



Thanks to all for your time!
Also thanks to Admin MIUI Community!
