Some Sony apps updated to compatible 6.0 now usually it indicated the 6.0 is coming soon but I think no earlier than Feb end.
I think so too, maybe even at the begin of march
But my question was only about the kernel ;)

Do anybody know, if the old twrp for lp will work for marshmallow (i mean to flash supersu, for the case tommy will build a new custom kernel) or is there any other way to get root?

Hi guys!

I would like some help from a kind soul.. I installed this kernel with twrp but.. If i wanna boot to recovery/twrp i have to use fastboot. Back in the days with my z3c and on my z4 tablet i can do it with volume up or trough an app. Isn't it possible with this?

I have androplus kernel on my z4 tablet and twrp is booting perfect with volume up. So i decided to try to install androplus for my z5c with twrp. It installs and everything seems fine. Then i look at "about phone" and it still tells me i run the zombiekernel - what am i doing wrong guys? :D

Maybe you should try the reflash the stock kernel with flashtool and reflash androplus... Not sure if it works

Just a quick status update: A new kernel build will be available after MM is released.
I already refactored my Source and set all things up, plus checked the Docomo 6.0 kernel source.

The new kernel builds are going to be more security oriented, and are going to get regular bugfix-patches from linux upstream.
Will it suppport root?

Yes. I do maintain a personal and a public branch of my kernel tree. The public branch has RIC disabled and Sound-Control added, and is going to be released on XDA.
Very nice
Just one thing, what about the brightness changes, which you wanted to make?

Thanks. Since MM has been finally arrived on Z5c yesterday, I'll recommend to lower the A57 speed to 1344mhz to see the result of further heat reducing bcoz summer is coming later.

MM is much faster and smoother on Z5 line based on all reviews(I will flash it today or tomorrow for testing), we don't need again with that highly clocked of A57 to generate heat and wasting battery. 1344mhz should be more than enough for just a 720P device on lighting fast MM. Alternative suggestion is to lower A57 to 1344mhz but restore A53 back to stock 1555mhz.

I've a chance to play with Samsung 5.7" A8 for two days last month and it used SD615(quad [email protected] and quad [email protected]), that phone is very cool and never heat up and that is running on a FHD screen. I'm pretty sure the heat issue comes from A57 on our phone after tested A8. I believe reset A53 to stock speed is safe whereas should lower A57 as much as we can after MM released.

It's not that easy. The SD615 uses a larger manufacturing process.
There will be little to none effect when clocking down further. 1.3/1.5 GHz are the optimal limits.

The device will heat up in summer regardless, at least the grey one, because it absorbs light waves. Lowering the clock freq won't help anything.

It's a bit hard to tell without testing. SD810 produced by 20nm HPm and SD615 used 28nm LP. But our Z5c is running 720P only and we are powered by SD810 GPU which is an overkill. I'll try to lower it by myself to see but have no idea which app allowed to adjust individual core speed without changing the kernel code. I think optimal limits might be 1.3/1.5 for best performance but I'm looking for optical limits for heat reducing and don't care a bit lag.

I based my patches on a power curve analysis done by anandtech (of the exynos 5433, which uses the same process). Of course things slightly differ here, but my testing shows that like on the exynos, 1.3/1.5 GHz are the efficiency limits. My goal is not to underclock as much as possible, but to find the sweet spot of performance and energy consumption.

I finally found a mm ftf file (generic, uploaded by furrydaus) and waiting patiently for a working kernel :)
