修改MAC,没有nvs_map.bin时该怎么做

Basically: nvs_map.bin is what is used to set you MAC address, part of calibrating, as well as other parameters that I won't get into here (can check out the other posts as I make them if curious). So if your wifi is acting weird, keep having your MAC change, getting calibration errors, etc... check /pds/wifi/ and /system/etc/wifi/ for this bin file. If its not there than this is how you make it:

Both may work or one of the two, depends on how cranky your phones being. Either way manually execute them via rootexplorer or scriptmanager. After you execute it you'll notice a whole crap load of folders got made in the directory....its fine, take a breath and leave them for now.
