[ROM[UNOFFICIAL][7.1.2] LineageOS 14.1 SM-T700] Thread

Last update Deathly version or Vanilla version

difference deathly and vanilla

1. Exynos5420 builds feature Deathly kernel by @deadman96385 It is a feature-rich kernel with patches like UKMS, GPU volt control, CPU overclock etc. However it is not very stable compared to the LineageOS kernel used in official builds and my builds linked.

2. Exynos5420 builds add Deathly Adiutor and LineageOMS to the source tree. This allows theming support with Substratum. LineageOS builds lack this functionality, per LineageOS charter.
