crap, it still not working... my mac still 0... plz somebody heulp me T_T
no. backup won't restore it.
you have to find your mac address and manually add it back.
you will find it using a binary hex editor and opening with it your misc partition.
then copy your real mac address into /data/misc/wifi/config
Must look like this :
cur_etheraddr=00:00:00:00:00:00
replace zeros with your mac address. reboot, fixed.
how to edit misc partition ?
dd command to extract your misc partition or SALT of
@steadfasterX and open it with a hex editor.
happy fixing it and never format or erase everything again. only wipe whats needed and thats the data partition.
