DOWNLOAD KERNEL ZIP

FKM download configs: oos | custom

(No mirrors please)​

Setup and troubleshoot: To install just flash the zip on a stock setup with either TWRP or autoflash kernel app.

If you come from other kernel or have any issues, you should restore your stock boot.img or dirty flash your ROM before flashing blu_spark zip to avoid problems. Also uninstall or clean data of any kernel control app you're using.

If you are upgrading between blu_spark versions, just flash the kernel zip.

About bugs and reports: 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 OOS ROM with NO mods whatsoever (apart from root). That includes NO support if using xposed, Magisk with added modules, etc.

If you're using custom ROMs (including stock based ones) and OOS Open Betas you're much on your own. I'm mostly interested on debugging stuff in stock and stable OOS.

Also try not to spam the thread with OT. There's threads for all kind of stuff, use them.

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