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.

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

Nice! New kernels to play around with :highfive:

Quick question: Can I flash this over ElementalX without having to dirty flash my ROM?

Just flashed it over PA. So far so good! Will be reporting back in a few days on the kernel's overall performance and battery life.

The reason I ask this is because the ROM I use comes with ElementalX. So, I'm not sure what I'm really suppose to do :silly:

Is there compatability with CAF ROMs like CM?

Hey guys,

Just a forewarning - I tried flashing this kernel on top of my current setup. I'm running the latest Mahdi ROM, and was previously using Uber kernel saber 4.9. I used TricksterMod to set the settings, but before I flashed this kernel, I made sure to turn off the setting that keeps my previous kernel settings locked for the next boot.

After I flashed Purified, my phone booted fine, but got stuck at the boot animation. No biggie, so I just restarted it. Happened again, so I went into recovery to try to reflash my ROM to get back the stock Mahdi kernel then try flashing Purified again. However, I get an error message saying "E: Can't mount /sdcard".

I'm kinda stuck now...this is the first time I've experienced a soft brick like this. Does anyone know how to fix this? I can't even go back and restore my old ROM and kernel setup because of that error message.

EDIT:
Sorry, kinda freaked out just now because I've never had so few options for recovery. No access to reflashing my ROM, no access to nandroiding. I tried ADBing, but couldn't set it up right and my device wouldn't load.

Out of desperation, I factory/data resetted, rebooted, got stuck at the boot animation screen, rebooted back to recovery, then tried accessing the sdcard again. ...somehow that did it. My sdcard was back and I nandroided. I still don't really know what caused this to happen.

I'm guessing, next time just to be safe, reflash the ROM, and then flash over this kernel?

@eng.stk

Thank you and welcome :good:

Ah,finally! Thank you @eng.stk

What the main differences between this release and the default Purity kernel? I know you and @DariosF work together from time to time and he has implemented some of these features into the default purity kernel.

Try mounting options in TWRP, also try a fix permissions.

Looks like you got something wrong with your ROM, just dirty flash it

Me and Dario work almost everyday together, we made stuff for almost every Nexus (at least).

The diferences are in OP, I use same base but to a diferent end.
