TODO list

General

• Warn before backing up current MAC address that it should not be spoofed at the moment (important)
• Add support for selecting specific vendors to spoof (ex apple, samsung etc)
• Search for device specific files on first run (due: version 2.0 Final)
• Add a button that deletes the backup file in case the user wants to uninstall the app (maybe)
• Add support for more models
• Remember previous MAC addresses
• Change application icon
• Support older Android versions again

Important files

General

• /efs/imei/.nvmac.info
• /data/.mac.info
• /efs/wifi/.mac.info (works on SGS3 mini)
• /efs/wifi/bt_addr
• /etc/calibration
• /etc/wifi/

Newest method

The method above overrides this method (at least on SGS3 mini). It will only work if /efs/wifi/.mac.info is missing, or an address that cannot be applied is given.

• /sys/module/dhd/parameters/nvram_path (nvram_path will do)
• /etc/wifi/nvram_net.txt_GPIO4 (works on SGS3 mini - defined in nvram_path)
• /etc/wifi/nvram_net.txt
• /etc/wifi/nvram_mfg.txt
• /etc/wifi/nvram_mfg.txt_GPIO4

Ideas for implementation

/etc/wifi/nvram_net.txt_GPIO4 contains lots of data, other than the MAC address. So:

• Use regex in order to find the MAC address instances in the file and replace them with the new ones (expression: ([0-9a-fA-F]{2}(:|-)){5}[0-9a-fA-F]{2} )
• Keep a backup of the file that will override the newest method and delete it
• Use a MAC that cannot be set in the file that overrides

Thoughts

• What happens if a MAC that cannot be applied is given in the newest method?
