Compatible with Kernel Adiutor and others

DOWNLOAD KERNEL ZIP (No mirrors please)​

Warning: If you come from other kernel or have any issues, you should dirty flash your ROM before flashing blu_spark zip to avoid problems.

Reflash ROM -> if you want root flash SuperSU or Magisk (default, no plugins/modules) -> flash blu_spark.

If you are already rooted or upgrading between blu_spark versions, just flash the kernel zip. 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. I only active support stock ROM with NO mods whatsoever (apart from root). That includes NO support if using xposed, Magisk with modules, etc.

Save the SOT and battery stats/screenshots for general threads, here we deal with development, not personal tastes and results.

Also don't spam this thread with LOS or other ROMs stuff like "this don't work, my app doesn't open, etc" , no OT about OTAs, apps, ROM bugs, Recovery/TWRP troubleshoots and other userspace stuff. There's threads for it, use them.

Going back to stock: This kernel installer doesn't change your filesystem. You can backup your boot.img with TWRP before flashing blu_spark if you want to go back to full stock or just dirty flash your full ROM.

If you like my work, donations are always welcome.

Don't forget to hit thanks and rate the thread nicely, it's free ;)

Red Magic development unit donated by Nubia. Big shouts to them :)

Special thanks to Adam K. for being such a supportive person.
