Hello everyone welcome to my little guide on how to change the mac address of the mi pad 4.
I plan to release a app or at least binary in the next few days to speed up the process for u 
Requirements:
- Root
- a hex editor
- a Mi Pad 4
MAKE A BACKUP OF THE PERSIST FOLDER BEFORE!!!
Open the Hex editor
Open the file /persist/wlan_mac.bin (obvious name xiaomi)
The layout of the file is as follows:
It contains 3 mac addresses - one primary and two for fallback(s)
The addresses are displayed in HEX - every hex digit represent two numbers of the mac address
a possible content would be:
20 a4 0f 5b 34 24 20 a4 0f 5c 34 24 20 a4 0f 5a 34 24
To change the actual address simply change like a few bytes of the first address
20 a4 0f 5b 34 24 -> 21 a2 ff 4b 24 34
and reboot the phone.
DO NOT ADD ANY DIGITS THE FILE HAS TO BE 24 BYTES BIG!!
Thats all but be careful with changing the digits not ALL possible combinations are allowed by routers!
Remember that HEX digits are: a-f and 0-9
Feel free to leave a reply or leave a thanks if i helped u.
