I have a problem with my XPERIA P(not rooted or unlocked), it wont boot if the cable is on the phone(pc or wall charger) and doesent even charge. When tryong to boot it shows only the SONY logo, not even xperia(which comes right after sony).
Tried getting into flash mode or fastboot mode, but it is the same thing.
If i switch on my phone with no cable plugged it starts normally.
When this happened i had no battery at all. After searching the web i found a guide to open my phone and remove the battery connector. After removing it and plugging back again it started charging. Now it wont charge anymore that way.
EDIT: Mac wont recognize it anymore(mac bridge, flashtool, adb)
Does anyone have an idea?
