Seems you have broken NAND-memory (4GB chip) which contains all system, data, etc.
Now 8 (!) people on forum experiencing this: you and this 7 1, 2, 3, 4, 5, 6, 7
Info about Encryption unsuccessful
Phone tries read partitions and due some reason data there messed up.
It's looks like encrypted data for phone and he trying deal with it.
Googling says that this is consequence of broken NAND-memory.
Seems not, hard to say what reaction will be there.
what is the rough cost of replacement of NAND memory?
I guess repair center suggest you to replace whole system board.
there is only solution..go to authorised service centre and they will replace the motherboard (PCB) and update your phone. i have also the same problem with my xperia m dual
it just big problem in internal memory like a NANDROID Partition is damage...
there is no way to fix this...
only one chance to replace hardware system bro...
That's nonsense! They're just basically going after the money. You don't have to replace the motherboard, that's rubbish. All you have to do is to download Flashtool by Androxyde, make sure that you have installed the proper drivers, download any FTF from the Android Development section that suits you, then flash it. If you need a more detailed explanation, then just reply...
I am having the same issue, and got the same reply about the motherboard from the Sony centre.
Could you kindly guide me on how to go about this?
I am a novice at this and have never flashed my phone before. Kindly advise how to.

Try older Flashtool version, e.g. some from 2014
