[HELP] unable to boot in custom recovery or updating CM

[tilencow]

My brand new OPO came with CM 12.0-YNG1TAS2XK.

Unlocking bootloader went fine, when flashing TWRP it booted in stock recovery, i tried going in recovery after flashing it, but it booted in CM.
Flashing CM nightlies via cm recovery gives me error, so i am stuck with this version.

Any ideas?
