Hey guys,

I'm currently on a fully GPE converted phone running stock Lollipop 5.0.1.
I have S-Off, root, TWRP and Xposed.

I'm planning to flash the Quantum kernel on my device mostly to get KCAL support (LCD color switching), but also for the supposed battery improvements.

I'm obviously going to take a TWRP Nandroid backup prior to flashing the kernel so that I can restore back if something goes wrong. But what I'm wondering is, if I decide I actually want to go back to the stock kernel at a later date (say in a month), is there any way to flash just the stock kernel or back up my current one? I can't seem to find a copy of a stock GPE kernel, can I compile it myself or something similar? I'd prefer not to have to do a TitaniumBackup and use an RUU since that's such a load of effort.

I'm a software engineer so no need to sugar coat any technical details for me. :)

Thanks!
