I know aosp roms are much lighter than others but I like miui based rom. which kernel do you suggest about?
Yes, modifying system voids warranty. To claim warranty we can flash stock fastboot rom anytime. Fastboot zip has stock boot image & recovery image which can be flashed separately whenever required if you're on official miui.
* Your warranty is now ... void?
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this Kernel
* before flashing it! YOU are choosing to make these modifications, and if
* you blame me for messing up your device, I will laugh at you.
Not sure, pushing out a new update in the next hour.
