Default [Q] Bootloader unlocked factory reset

Hi,

Today I tried to unlock my bootloader on Xperia T, because I recently downloaded android 4.3. When the bootloader was unlocked, I tried rooting the cell through usb debug. But it didn't work, I decided to look at it tomorrow, or at a later point. But when I restarted my phone, it was been factory reset. Some of the photos were recovered, but ALL my notes are gone and a lot of apps are gone, I never chose to format my phone or anything.

Is there a fix for this issue?

Thanks in advance!

EDIT: my phone contacts seem unlinked from WhatsApp too... So the contacts are there, but WhatsApp doesn't recognise them.... I think the internal memory and the phone memory are corrupting each other

EDIT2: the contacts don't even seem to be there now, not even on Google, while I am 100% sure I saved the contacts to my Google account
