Hi - i bought a 2nd hand phone and in case there is any spyware on it, i want to delete everything on it, including all the system folders using clockwork mod. is this safe?
i am wondering, will the imei numbers be preserved ? (ie, are they actually written on a chip that is read only, or are they in the system folders too?) i am wondering this with a few model phones --- galaxy nexus (which i believe does get the imei reset), sony xperia t, nexus 4, etc
