Need help on Flashing Xperia SP C5302. Its gone dead while flashing.

I'm using Xperia SP from 3 years. Recently, I was about to flash CM12.1 Lollipop ROM.

I did these things seqentially as below -
1. I rooted the phone via Towelroot app.
2. Backup DRM keys with Bakup_TA_Master.
3. Then, Unlocked the Bootloader via Fastboot cmd. (link : http://forum.xda-developers.com/show....php?t=2354721 )
4. After that I flashed CWM v6.0.3.5 & created full Backup.
5. Wiped Chahe, Dalvik Chahe, Data & System.
6. Tried to Flash CM 12.1 ROM (downladed from LINK: https://github.com/CyanogenMod/andro...e_sony_huashan )

BUT soon after a few minutes of installalation my device showed an error message and it shut down and doesn't started.
It don't shows bootloader, no SONY logo, not reboots to CWM Recovery. It is almost dead, But.....
The only two things it allows me to do is boot to Fastboot Mode & Flashboot Mode when connecting to PC via usb cable.

I dont know what to do now..........

RN2 side buttons gone crazy

Hello, I own the RN2 for months now and it worked fine. Until recently my Volume buttons got a mind of their own. out of no reason my phone would raise or lower the volume like a button was pressed. My power button refused working along too a few times. I'm not sure if it's a hardware problem or a software one. It's quite annoying tbh. the problem was there no matter of the case (original white + silicone protector, without protector, aftermarket black + protector, without protector, without any case.... )

Has anyone experience with this problem? Should I order new buttons and change them or?
