@Keneda Ok, i did manage to fix this, but after running mka mkbootimg, i got this error:

@keneda The codename on the lineage os github is n8000. And i dont know why it is not on the official website, but it is on their github https://github.com/LineageOS/android_device_samsung_n8000 EDIT: I did manage to build lineage 14.1 stock, but not halium.

@kingpronoob2 This is the output of breakfast n8000.

including vendor/cm/vendorsetup.sh

** Don't have a product spec for: 'lineage_n8000'
** Do you have the right repo manifest?

@domubpkm Yes, that's it.

So, i have followed the guide on the website how to port and i created the local manifests and everything, but when i went to run source build/envsetup.sh, it didn't return my device. I have put the proprietary blobs to a few locations in the vendor folder like: "n8000", "samsung", "n80xx" but nothing works. Thank you for any help.
