after executing the repo sync when iam executing the lunch command it was showing errors like this
**Dont have a product spec for: ‘msm8916_64’
**Do you have the right repo manifest?

but i had downloaded and intialised the repo .
plese prove me the solution.

Do you mind letting us know which instruction you are referring for building the kernel?

This is the link of the documentation we have released but it is for Debian.

And this is the link where the android builds are hosted.
