Thanks for your fast response.Just flash the kernel. You may need to be decrypted on F1 for it to boot properly.
The clean kernel flash procedure doesnt remove any app. Its not a rom clesn flash. You dont wipe data nor system
I read in a previous post from @Retrial that "NGK working fine in crDroid encrypted (no root) which is also based on los." works fine - will this also be in the future? I'm not so familiar with encryption / decryption therefore I would prefer to keep it as it is, just install your kernel.
