Default [Q] [ SOLVED ] [ YP-G70 & YP-G1 ] Three Players, One MAC Address

I have three SG Players, two 5.0 and one 4.0 that have been having trouble connecting to my home wifi.

The 4.0 is running CM11 (cm-11-20140323-UNOFFICIAL-ypg1) with the Impulse r6 kernel.

One 5.0 is running CM11 (cm-11-20140113-UNOFFICIAL-venturi) with the Jan12 US kernel.

The other 5.0 is running CM10.2 (cm-10.2-20131105-UNOFFICIAL-venturi) with the Nov4 US kernel.

I poked around and discovered that they all have the same MAC address, and the two 5.0 players have the same serial number. I tried various MAC spoofers and changers without any success. I tried wiping and reflashing one of the 5.0 and the 4.0, but the addresses did not change.

Does anybody have any suggestions on how to change the MAC addresses?

For the 5.0 player you need to edit the /vendor/firmware/nvram.txt . There is a line that starts: macaddr=

Make sure it sticks, you got to remount,rw /system before you edit!

You should be able to make up any "valid" mac you want...

Been meaning to fix this but... working on other stuff at the moment.

As @Meticulus said, the same thing applies with the 4.0, only that the file is /vendor/firmware/nvram_net.txt.

Gentlemen,

Thank you for the help. I was not able to try your suggestions as the computer here at work is locked down.

As both of you mentioned a text file, I looked through the cm-11-20140323-UNOFFICIAL-ypg1.zip file, found and edited /system/vendor/firmware/nvram_net.txt to modify the mac address. After saving the modified .zip file, I flashed it and my 4.0 now had the revised MAC address.

I then took the opportunity to update one 5.0 and the 4.0 to the latest CM11 (cm-11-20140414-UNOFFICIAL-venturi and cm-11-20140421-UNOFFICIAL-ypg1, respectively), after modifying the MAC address for each .zip file.

Thank you for fixing the headset button on the 4.0!
