I'm here to warn you guys that the themes of Sony, those new (cute) themes simple put our Xperia SP to bootloop, don't use them in any circunstances.
I've made a lot of test in the firmware 184.108.40.2066 and when i put any of those damn themes and turn off my phone, it justs enter in bootloop mode when i try to turn it on again.
Then i have to use SUS to recovery phone.
DO NOT USE THE NEW THEMES IN ANY CIRCUNSTANCES.
UNFORTUNATELY SONY MESSED UP OUT PHONE.
just wanna warn you guys, sorry about the english.
