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
If you like my work, donations are always welcome (but not mandatory).
