UNABLE to boot into system or recovery. OEM unlock fails. [BOOTLOOP] [ENCRYPTED]

Here's what exactly happened to my Oneplus2 -

I had successfully unlocked the Bootloader and flashed TWRP using Fastboot.
Using TWRP, I flashed SU Binary and got root privileges.

STUPID Step : I enabled ENCRYPTION on the device.
Which made it impossible for TWRP to mount the encrypted drives. But even after that I was able to boot into Recovery.
Everything was fine (obviously, I wasn't able to flash through TWRP though, due to encryption)

After some days, when I tried to boot into TWRP, the device got powered off promptly just after the boot animation flashed on screen (which hardly lasted for a second)
I don't know what happened. I was not able to reboot device into system either. It just flashes the boot screen for a second and then completely goes blank. Same is the case if I try to boot into Recovery (using Power button + Vol button)

[Currently] I am able to power off my device and boot into Fastboot Mode (using Vol Up + Power)
I tried flashing TWRP again but it fails giving the following error.
Command - fastboot flash recovery TWRP.img

OKAY [ 0.859s]

FAILED (remote: device is locked. Cannot flash images)

So I checked whether the Bootloader is still unlocked? (And unfortunately it is locked, I have no idea how)
Command - fastboot oem device-info

Quote:

...

(bootloader) Display panel:

(bootloader) exec_console_unconsole: 0
OKAY [ 0.078s]
finished. total time: 0.078s
I tried to unlock the bootloader again but still the same result.
Command - fastboot oem unlock
(I'm sure that OEM unlocking was checked and even USB debugging was enabled last time I was booted into the system)

The bootanimation flashed for a second and then again nothing happened. I again checked the bootloader status. It is still same as quoted above.
I rattled a lot around many forums to get a way to boot into the system.
So what tried was to use this command.
Command - fastboot continue

Quote:

resuming boot...
OKAY [ 0.008s]

Only a charging screen appears. And on removing USB same thing happens. Device gets powered off and on trying to boot again bootanimation comes up for a second and then blank screen.
I really have no idea what to do? Any help would be appreciated.
Thanks!
