[SOLVED] Change wifi MAC Address

Cicar · Jan 17, 2011

I have succesfully changed wifi mac address of my optimus.
We have to just insert a line "macaddr=XX:XX:XX:XX:XX:XX" in the nvram.txt

Here is how I did it:

You require:
1.)Rooted phone.
2.)anroid sdk

1.)First pull the nvram.txt file from /etc/wl to sdcard:
in cmd(windows) goto android-sdk-windows\tools and type
adb shell

2.)Copy nvram.txt from /etc/wl to sdcard
cp /etc/wl/nvram.txt /sdcard/nvram.txt

3.) Using text editor in phone add following line at the end:
macaddr=XX:XX:XX:XX:XX:XX (replace XX:XX:.... with desired mac addr.)

4.)Save file and copy it to /etc/wl from adb shell
cp /sdcard/nvram.txt /etc/wl/nvram.txt

5.)Reboot and it is done.

To restore orignal mac address just delete the macaddr line.

Note:

1.) Tested only in stock LG rome with GNM OC kernel. In other roms or kernel the location of nvram.txt may differ according to the parameter using which driver module (wireless.ko or bcm4325.ko) just find that file and use the above process. It will work.

2.) The file cannot be edited in windows as windows has different new line character than linux. It has to be edited in some linux compactible file editor like Programmers Notepad.

And to change hostname? Any ideas?
I changed it, and in phone it appears to be changed. But my router doesn't say the same... Has original hostname...

my computer can't detect that was a file in computer,and what is the android-sdk ?

Screw android-sdk ..LOLz..Do this install root explorer on your phone ..navigate to that file on your phone using root explorer , click on mount r/w button ,then long press and select open in text editor, then go to the end of the file and add this
macaddr=xx:xx:xx:xx:xx:xx

replace xx with a combination of hex letter i.e. 1,2,3,4,5,6,7,8,9,A,B,C,D,E,F
example DB:12:3F:4F:11:AA
Save and exit
Reboot
You are all done check phone status in settings
