Nice work, but androidfilehost dont work

 

[dodo99x]

Works fine for me

 

[jimbob_sf]

Can the op be updated to say what roms this will / won't work with? Will it work on CM11 or is it only for TW roms? Thanks!

It's for TouchWiz only

Hi @civato . Can i flash this kernel on SM-p901 ?? it's the same as SM-P900 and both of them are exynos and the only difference is that SM-P901 has sim card slot and 3G capability ! would you please compare the kernel sources of sm-p900 and sm-p901 and if they are the same , i flash it on my SM-p901 ?? Thanks.

You can always flash it, no harm will be done. However, it might be that some settings of the 3G capability is integrated in the kernel, and you will loose this. There is no verification in the kernel if you flash it on the right device. If there are any issues, just restore your stock rom.

• F2FS & Battery control removed
• Min Screen ON frequency is now set at 177MHz by the hotplug driver
• CIFS supported fixed ( my bad , forgot some stuff in the ramdisk)

Tip:
Use the Screen option in synapse and enable register hook & the edge enhancement and see a real sharp image.

 

[golfinggino]

I just flashed this latest kernel and running great, I have a question about enable register hook and edge enhancement I did this and everything looks dull / washed out is there any other settings under the screen options I need to change?

 

[pichuerca]

Awesome work!

Thanks for the kernel! awesome
By the way with the lastest kernel i have still experimenting some lags. Is there a way to disable the synapse tool?
This happend me constantly so ist's a bit uncorfortable when i am writing and the tablet freezec for a moment (3 seconds)
thanks in advance

Keep getting signature errors, and cannot install

Hi, I tried to install this kernel, but keep getting signature errors, and it reverts back to restore.
I wiped cache, and all, and seem to be stuck. Is there any way to make a tar file for odin? I don't have Linux , and changing the extension only corrupts it.
I would like to change the stock kernel on my smp900, as the knox counter tripped with kies, and Samsung voided my warranty for (new tablet :crying: - even sent it in and they didn't reset it, after the had admitted it was a problem)
If you can't make it a tar file for odin, what is best to use to install this?

Thanks

Can you make this kernel specifically for SM-T900? (TabPro12.2 WiFi)
I've flashed this kernel in my T900 because they're almost the same except for the Pen software and feature and every thing worked smooth and excellent but "rotation" breaks down, it doesn't work even on apps so no tilt function. Hope to hear an answer Thanks. It runs so smooth that I want some of the butter for my Behemoth Tablet lol

 

[Sterist]

this should not be labelled as stable. it's the one and only kernel I've used that crashes n sometimes it will reboot while sometimes it needs to be done manually

about 3 to 5x a day on 8 to 10 hours of use a day

SM-T900 uses different hardware for screen rotation, can't make it work with this kernel.

Not having it , your problem not mine. Running 24/7 stable. At 2.1GHz and 677MHz gpu.
so before *****|ng you should probably learn how to logcat and see what is causing your problem.
so this should be labeled as stable, you on the other hand?

I have to agree with the previous poster - your experience is not typical. I have installed this kernel every time a new one is released and it gets more and more stable with every release.
You need to look at the tweaks you have made and what apps you have installed.
Asking for help and hints would be far more productive than a hit and run.

Have you considered building this kernel for the P905. Not sure if it is possible without having the specific device on-hand. Regardless, sounds like you have been able to improve performance for the P900 - congratulations on your work. Hope you have Happy Thanksgiving if you participate in turkey day activities.

Works great for me as well. No issues here, over clocked and undervolted.
