Just tried to install and then boot into CWM, it shows a pink LED at the Sony logo. Pressing either of the volume buttons makes the phone hang and then reboot. I will report with philZ recovery once my phone rebooots.
EDIT: philZ recovery produces the same result.
EDIT 2: All recoveries produce the same result on my device.
