Flash whatever rom you are running again, that will restore the boot.img. Then flash root if needed and Blu_Spark. No need to factory reset, you will keep apps and data this way. I usually keep the boot.img from whatever rom I have handy in case I need to restore it for some reason.
Accidentally left my screen on last night and it was chilling in the morning!

Thanks for being supportive guys, this keeps the spirit alive
Stock ROM and LOS 14.1 for testing.

Nope, kernel is device dependent.
This is only for this device.

Settings still not applying after reboot. I always manually adjust kernel everytime I reboot.
And you should be doing some digging on your own since it applies just fine for everybody else.
Anyways:
1- What settings specifically are you talking about?
2- How are you setting them? App/script? If app, Apply on boot checked?
3- What ROM?
Apply on boot works as expected no matter how I set it up. KA, ExKM, scrypt.
Double check you process.

I'm running the latest LOS 14, and with stock kernel it is very smooth and works perfectly.
But as soon as I install BluSpark, the phone gets slower and slower of the next couple of hours, until even opening the app-drawer takes 5 seconds.
After a reboot, everything is back to normal. Until is gets slower again.
It doesn't matter what settings I choose - happens even with stock settings.

You're using a phone with 2GB of RAM, deal with it.
You can tune LMK to your own needs, it had been discussed several times.

Thank Eng, for giving a direction to look at.
I was just curious why there is no problem at all when using the stock LOS kernel.

DOWNLOAD KERNEL ZIP (no mirrors please)
Warning: If you come from other kernel, you should dirty flash your ROM before flashing blu_sp★rk zip to avoid problems.
Also uninstall or clean data of any kernel control app you're using.
About bugs and troubleshoots: don't bother to post if a log isn't ready or without steps so the behavior can be replicated. Also, I only actively support stock ROM with NO mods whatsoever (apart from root).
No support will be given to custom ROM including N stuff, so don't clutter the thread with it (specially):
- No talking about WiFi and N issues.
- No talking about ROM related and misc N issues.
Also no OT about OTAs, apps, ROM bugs and other userspace stuff. There's threads for it, use them.
This kernel installer modifies your filesystem, backup your boot.img with TWRP if you want to go back to full stock (or you can fastboot boot.img or dirty flash your ROM also)
If you want to use F2FS, do the following (backup your data before attempt this, it will erase all your Data)
- Flash TWRP with f2fs support and flash latest blu_sp★rk zip
- Go to Wipe -> Advanced Wipe -> Select only Data -> Repair/Format File system -> Change partition type to F2FS
- Go to Wipe -> Advanced Wipe -> Select only Cache -> Repair/Format File system -> Change partition type to F2FS
- Reboot and profit

All right crew!
Back to the heavyweight jam :angel:
I decided to reopen the thread after some thinking and some nice talks I had with several people.
I do this for fun, so behave and don't make me regret it.
This is for Lollipop 5.1 ROMs only.
The zip uses anykernel installer, this means it uses previously installed ROM kernel Ramdisk.
If already have Code_Blue or ROM default kernel installed just flash over.
If you come from other kernel dirty flash you ROM and flash Code_Blue after.
