So, I'm building my very first LineageOS 15.1 ROM with the files I got from Stock Android 7.1.1. I don't have a phone to test it yet, so I decided to collect some info to improve it.
My device has a chipset MSM8937. The latest Android version was 7.1.1 by the time I started to mess with the Lineage, now they released 8.1 for the device.
1- If I want to build LOS16.0, am I supposed to replace the proprietary files with a device with LineageOS 16 and same chipset's proprietary files?
2- What kind of changes I have to make when using files of a lower Android version to make a higher Android version?
Thanks in advance.
