I did this process base on the following link:
"( https://geekeasier.com/change-mac-address-in-android-devices-without-root/4792/ )
Open up settings and then go to WiFi.Now, you will see a gear on the top of this screen, click it. But if you don’t see it, look for “Configure WiFi” option and click it. Some Android system have Advanced option in WiFi, MAC address can be found there also.Voila ! You can find the MAC address on the bottom of this screen. Keep a note of it.In order to get the interface name, you will have to install Terminal Emulator for Android. Go to Google Play Store and download it or click the link to get it.Once you download it, install it and open up.Type the following command : ip linkYou screen will be filled with lot of information, useful and useless. Now, remember I told you to keep a note of your MAC address. Just look for this MAC address under “link/ether” for all the cases.The one that matches our MAC address, is the connection name. For most of the devices it is either “wlan0” or “eth0”.Now, that we know our MAC address and the connection name, we can go on to change the MAC address with this terminal emulator only. Before that you should have a valid MAC address in your mind or generate one from this link. Once, you have a new MAC address, just get on with the below steps:
- Launch the Terminal Emulator
- Just type the following command: ip link set wlan0 address XX:XX:XX:YY:YY:YY, where wlan0 is the name of the interface and XX:XX:XX:YY:YY:YY is the MAC address you want to set.
- Important thing to keep in mind that the manufacturer name should be kept unchanged while changing the MAC address i.e. XX:XX:XX (first 6 digits) should be same as before, otherwise you might face a lot of authentication issue.
- This is only a temporary change and when you restart your device, your previous MAC address will be retrieved back."
I have an error "Operation not permitted"
What should I do now?
