Intro
This kernel was made for my own personal use but seen as I had an updater app for tornado kernel which has been abandoned I have decided to share both the kernel and updater app here. As this kernel is mainly for my own personal use I will not be adding all the bells and whistles. If you prefer performance along with battery over power than this may be for you.
Install:
You need:
- Stock 20A, 20B, 20C or 20D -- Marshmallow
- H815 ONLY
- An unlocked Bootloader
- Custom recovery
Via recovery: latest TWRP here
- Download the kernel
- Reboot to recovery
- Flash the zip file
- You're done! Reboot and enjoy.

Thanks, the app is up now. I thought I had pushed the changes before I reset it, but didn't so had to rewrite some of it. Apologies for the delay.

---

No problem, glad to see new stuff around. I like the combos (mod + settings app), in this case kernel + app
Thx

Can you please explain the issue a bit more as I haven't issues with the external SD.

Of course. After booting the system informs that the external sd is corrupt and wants to wipe it. After returning to stock, issue disappeared.

Thanks. I haven't any issues and tried a couple of sdcards. I remember this being an issue in tornado kernel and savoca fixed it. Thought I had already included that commit but looks like it disappeared after the M merge. I'll add it back in now and update it if you could let me know if it now works for you?
Edit: Can't load the texfat module as it's signed by LG and it is not open source so can;t build it. Savocas hack is for some reason not working for me . Currently trying to work my way around this. So far no luck...

I've posted a version which should fix this as an aattachment here. As I don't have the issue I can't test to see if it's fixed but it should be. Please let me know if you get a chance to flash it.

I just tried. It seems the same. See attachment. Also getting the same adjust time errors from cile's kernels where somehow the hw time is set as system time each boot.... Thanks !

The time issue seems to be on all M kernels besides STOCK, even building bare stock kernel gives the same issue. It resets back to the proper time a couple seconds after boot but still annoying. I'll have to see if I can spot anything for that. Please try the attached kernel to see if it fixes exfat, thanks.

If this is of any help (higly doubt it but here goes nothing):
H815-EUR GERMANY
Using pre-rooted stock 5.1 KDZ = exFAT support breaks.
Pulling already set up 5.1 system and injecting it with root = exFAT works.
Using SuperSU zip installer on 5.1 = exFAT works.
Using prebuilt, matching, repacked 6.0 boot.img = exFAT support breaks.
Pulling boot.img from stock system state of own device and repacking = exFAT works.
Using Systemless Root = exFAT works.
How likely is it that the kernel is aware that it's not operating on the device it was first flashed/built for? Tbh, I don't know anything about kernel development. It's just, whenever I flashed a kernel that was pulled from another device or modified without ever touching another device, as it might have been the case in those prebuilt repacked kernels, exFAT support broke down.

Does FauxSound Mod increases sound volume?

On my Device the sd card have an error too after installing this kernel. I reinstalled Genisys Rom and now all woks fine. I will test the kernel at a later time again. :good:
