I seen someone asking about wifi modules.
I want to know. What function wifi modules?
Is it for wifi tethering feature activator??

sent by tapatalk via super xperia Neo

As far as I'm concerned, Modules are neccesary to make wifi working when they are not included in kernel.
however, if you go back to a kernel with built in modules, you must delete external modules, if they are duplicated, wifi will not work.

many kernels like nightelf, install its own modules, (they arent uninstalled flashing stock kernel) and if you return to stock, you must flash stock modules.

The correct command is

fastboot flash boot boot_ICS_plus_v4.img

and NOT

fastboot boot boot_ICS_plus_v4.img
