How to permanently remove wifi/bluetooth from an Android
I want to buy whole sale OEM phones from China and then permanently get rid of their wifi/bluetooth capabilities. I have been advised that I could do so through software/application modifications, but I also learned that any of these processes can be reversed by rooting the phone. I have heard that its possible to go through the hardware and manually remove the wifi/bluetooth chip/drivers to permanently disable them, but could not find any further details on the subject.
Does anyone know if this process is possible, and if so, how can I learn more about it/find someone who specializes in it.
