I bought a xperia P, used.
I think that the motherboard are a problem, because:
1.When i delete the intern memory or make a factory reset in my phone, after the reset the phone in the memory appears the all files, before i delete the memory.
2.When i connect the phone in fastboot or flashboot it is not possible, because i have s1 boot download problem or s1 fastboot download problem, but i installed pc companion, flashtool driver and all drivers.
So i dont know to make a firmware update or else.
