[Android Q&A, Help & Troubleshooting] TomKa10:
Hello there,

Today i tried Porting LineageOS 17.1 for ZTE Nubia X:

- I did my source code setup as described on wiki.lineageos.org

- I took the device tree from Mokee OS, and modified the files to fit Lineage

- I pulled the vendor files from the Phone using proprietary-files.txt

- I ran breakfast

- I ran brunch

So i got a few questions, and i think they are about Porting in general so i hope i'm right here.

Question #1:

The lineage/device/nubia/nx616j makefiles of the mokee source do point to lineage/device/nubia/sdm845-common makefiles, also the bash scripts for pulling vendor blobs from the device.

Does that maybe have tho do with my second problem, because my particular phone just don't needs these proprietary files?

Question #2:

When i pulled the vendor files, some(a lot of) files couldn't be found. Is that bad or maybe the cause of my third problem?

Question #3:

When i run breakfast, it suceeds(I think):

Trying dependencies-only mode on a non-existing device tree?
