OK then: Recently, the Xperia Play's screen has been broke. I just put in the new flex cable and THAT seems to work... except now:
- I can only start the phone on USB power, otherwise it freezes at the splash.
- If it boots, the touch screen doesn't work. As I can't unlock it without a touchscreen, I couldn't test it.
I did tighten the digitizer cable after this, no dice.
