Exclamation [NEED HELP] Encrypted Cyanogenmod 11M4

Hi!
I just encrypted the LG G2 (D802) and I'm just booting to a screen that sayes "Encryption unsuccesfull". Is there any hope to get this phone usable again? i have a full TWRP backup on my computer (includes: EFS, boot, data, system and recovery). I've also googled and tryid to find a solution, but this is my last hope.

Is there any way to just install cyanogenmod or stock firmware over the internal sdcard?

Thanks for the help
