type password to decrypt storage Xperia M

My phone has got locked by itself and is showing 'type password to decrypt storage'.
I can't move further than this...
What all i tried and failed at:
1) Repair using Sony PC Companion. But after getting started some error pops up saying retry. And this happened with the Authorised Sony Service Care personnel too. So I brought it back to home.
2) tried flashing using Sony Flash Tool. But right now my device is connected in MTP mode. And flashtool is urging me to switch ON usb debugging so as to flash the device.

Problem: As the device is locked now. I can't switch ON usb debugging.
Kindly help.

NOTE: I'm new to XDA and would appriciate re-corrections regarding this post. Thanks :)

Help Needed Bad on TWRP password

Password wanted by TWRP and I rooted my phone with Click To Root, I never gave them a password and when I try to do a Factory reset their screen comes up. to wipe, restore, and other utilities such as that. As far as the pass word goes I cant remember that and don't ever put one in just for this reason. Click to root support sucks because if I want to chat with an analyst it cost like .00 and they have a email support which I have heard nothing back from. also my screen is saying I have an available system update, I don't know if this has anything to do with the password?

Looking for a Gallery app which has live thumbnails and password protection.

As the title suggest i'm looking for a gallery app that has live thumbnails which plays animated media , (Like gifs ,mp4,webm).
I flashed a rom and has a gallery that does that,but that gallery has no options at all ,except from sharing.
I also cant find the name of the app in case there is an update somewhere out and there is an update to it.
The gallery app basically does this: https://vid.me/zXqY and i want something similar with locking function.
