Default HELP phone is dead after encryption, system not starting

Hi, I got Motorola Moto G, original system, no root. I just encrypted my phone, process most probably finished without problems - I stopped watching the phone on around 90%. Then it restarted, boot animation, "enter your password to decrypt the phone", I type it in, green robo shows for 1 second and then black screen (backlighted) :/ After couple hours nothing changes.
If I type wrong password, phone ofc doesn't acccept it. Computer sees device, but I can't access it. When I turn off the phone by pressing POWER for long time, it just resets and goes back to asking for passwod again.

Please help me recover my data...


EDIT
before entering password PC says phone is off, after typing it, PC says it doesn't have drivers (it worked normally before encryption).

EDIT 2
I can enter fast boot, but IDK what next. Recovery mode just ends with "NO COMMAND"

I see that probably all users who got this problem have Motorola Moto G too. Mostly people who use CM and tried to encrypt phone.

I downloaded Android SDK, fastboot.exe tool sees my phone in this state. Not sure if it can be used to do something useful....
adb.exe doesn't see device

Cyanogenmod is very buggy and in perpetual development state, not recommended.

Try this

So, I left the phone in black screen step over night. Battery ran out. I tried turning it on/off, entering fast boot mode, but nothing happened, then connected to USB. LED turned on for a while, screen too, showing battery with 0%. But now nothing again. Just black or off, not sure. Can't do literally anything, I tried pressing different keys for minutes and changing USB slot.

EDIT
nevermind, fixed battery problem, Moto G with no power needs normal charger or much longer time on USB

From what I've read, encrypted data on phone is protected by password and some kind of encryption key/file. Reflhasing firmware would cause permanent lose of that key and thus whole encrypted data.

The only solution I guess is copying that key on PC. Copying encrypted data if possible, and decrypting on PC using some tool, as Android is open source, so it shouldn't be a problem to extract it's decryption mechanism and run it on PC.
OR copying key to PC, reflashing phone, copying back key and praying this time system will start.
