Where can I get the default/stock rom that comes with the device?

Hello, I tried flashing and installing 4.4 nightly cyanogenmod. In the process, the phone messed up and now I'm stuck to android system recovery instead of safestrap. I'm thinking if I apply update from adb it would work.
Any ideas? How can I fix this? My system version was 98.30.1 iirc

Am I ****ed? I'm trying to fix my device and yeah, the bootloader is locked.
