Hello,

Which one works with kitkat 4.4.2?

Do this kernel allow the mounting points of network shares?

Thanks in advance

Hello [MENTION=4716493]laufersteppenwolf[/MENTION] and happy new year from me, too. Thanks for your work, just flashed on T210 tab with NoleKat v2.1+v2.2. Thinks look smooth, I and also wanted to report the "unknown" kernel in System Info. Is this something that's easily fixed? Perhaps edit the build.prop file? Hope battery won't be drained too fast :D

Guys, any idea how to show the CPU speed and info on this Tab III T210, in overlay screen, same way as those hidden menus on Android phones? I am not too experienced... Just to confirm the over-clocking values etc. Thanks in advance.

[Galaxy Tab 3 7.0 Android Development] HerroYou:
For the screen flicker, you just need to renable vsync

For better performance change the cpu freq. , governor, and I/O sche.

Hello everyone, a couple of questions that sound n00b despite my knowledge... :angel:

1. After flashing R007 of the kernel, on top of T210's NoleKat 2.1+2.2, does the CPU go directly to 1.420GHz as stated? I cannot really "feel" the difference (assuming stock speed is 1.200GHz? Not sure)

What is the suggested/best app to view in overlay mode the CPU usage (and other resources) like those found on phones? I saw a Galaxy S DUOS that had it, but it was part of 4.0.4 system menus...

2. Do I need some app to manage/control this "governor" thing? I have no idea to be honest that this even existed before... Any suggested ideal/best app for this?

Thanks again for anyone kind enough to assist.

P.S. To people mentioning it, I also get sometimes the screen flickers with R007 kernel indeed. :rolleyes:
[Galaxy Tab 3 7.0 Android Development] arifnasirshaikh:
Thank you for the answer.... After flashing this kernel on t211 screen flicker...? I searched this thread found out it is because vsync is disabled... Any way to enable it back...? Even i flashed stock kernel screen flicker.? Why is this?
[Galaxy Tab 3 7.0 Android Development] jstath1972:
To enable Vsync back as [MENTION=4716493]laufersteppenwolf[/MENTION] already said "you can write an init.d script to echo "1" to /sys/devices/platform/pxa168-fb.0/vsync".

Hello,

I have a problem with my T211 nolev1.2 and werewolf kernel v4.0

I can't see the kernel version i installed in settings.

Is this normal please? I didn't clear the /cache after zip flash.

What the purpose phservice file? Are this file annoying enough?
[Galaxy Tab 3 7.0 Android Development] jstath1972:
As [MENTION=3034891]gr8nole[/MENTION] already says "phservice will prevent you from being able to change governors, but it also does a pretty good job of helping performance. It detects how you are using the tablet and will adjust cpu performance setting based on what you are doing (such as watching video or playing games). Trying to manually adjust the cpu with apps while phservice is present will cause nothing but problems".
[Galaxy Tab 3 7.0 Android Development] ward0:
Could someone please respond. is it normal that my kernel version states : UNKNOWN

?
[Galaxy Tab 3 7.0 Android Development] jstath1972:
Hmm... seems that only I am around here:confused: Ok here we go then...

I don't know if it's normal but the v4.0 is too old. Update to v6.0 (my favorite). I recommend to you to wipe Dalvik Cache and Cache after the install & reboot. If you still can't see the kernel version in settings use CPU Spy app from play store to read the full kernel name.:)

Huhh just asking....

I had flashed it with 4.1.2 SM T211 by mistake and thought why isn't it working..... it was working for me in 4.4.2 but i wanted to degrade the android version and degraded to 4.1.2. If possible could you please make it work for 4.1.2 Jelly bean version buddy. It's just a request. I liked your kernel very much in 4.4.2 bro. If possible please could you make it for 4.1.2.:p
[Galaxy Tab 3 7.0 Android Development] Yatskie23:
Question.

Hi, Im new here and i have a SM-T211 (rooted SuperSU - TWRP 2.7.1.0)

Firmware - Kitkat 4.4.2 (Columbia firmware)

Kernel Version - 3.4.5-3209054

Will it work with my tab 3? Does the battery consumption increase or decrease with this kernel? is there any disadvantage if vsync is disabled? and last question, what are the benefits of lessen voltage? Sorry for the questions, i just want to know those things before i try. Thanks ^_^
[Galaxy Tab 3 7.0 Android Development] HerroYou:
Use the T211 labeled one. The only disadvantage of vsync being disable is a little screen flickering. The lessen voltage is for a longer battery life.
[Galaxy Tab 3 7.0 Android Development] konsti:
Hi HerroYou -- So there is no point in testing Kernel v006, right? I cannot find it in the downloads section/page anyway for T210 (perhaps removed by laufersteppenwolf) so you'd recommend we stick to v007?

Is there any expected release v008 at all, perhaps to fix the random flickering and the text/ID in the System Info?
[Galaxy Tab 3 7.0 Android Development] andynroid:
Deleted..
[Galaxy Tab 3 7.0 Android Development] HerroYou:
Did you try WWJB_v006_anykernel_KK_SGT3-2014-11-01_1923.zip ?

I am not sure if there will be a 008 release, you may want to ask laufersteppenwolf that questions. And to fix vsync I think you need to paste a line into the build prop or terminal.
[Galaxy Tab 3 7.0 Android Development] Yatskie23:
Will it work with TWRP 2.7.1.0? or need to change recovery?

Guys... There is a strange screen issue on my smt 210... Flickering like nuts,and locks on its own. Fix please?
[Galaxy Tab 3 7.0 Android Development] popliuc:
+1
[Galaxy Tab 3 7.0 Android Development] jstath1972:
@NiXEGaming and @popliuc

For the "locks on its own" bug revert from v7 to v6.

For the "Flickering like nuts" it is because the Vsync is disabled. To enable Vsync back as @laufersteppenwolf already said "you can write an init.d script to echo "1" to /sys/devices/platform/pxa168-fb.0/vsync".
[Galaxy Tab 3 7.0 Android Development] laufersteppenwolf:
If I may? :p

Guys, whenever you have some issues, always add a log (kmsg). Otherwise I have no chance of knowing what went wrong, hence no idea what I could do to fix it.
[Galaxy Tab 3 7.0 Android Development] laufersteppenwolf:
Alright guys, a new build has just landed on the servers ;)

It's not that much, but still should give you a slight multitasking boost. It is also possible that the "auto-lock" issues are gone, though I have no idea what actually caused it. It's just a wild guess.

And the usual changelog:

- Disabled zcache

- Added KSM (including deferred timer to save battery)

- Tweaked zRAM

- New kmsg log layout (see 2nd post for more details)

- Fixed kernel version in settings

- Disabled S2W and DT2W by default

When you flash this version, please wipe cache, otherwise bad things could happen ;)

enjoy! :)
[Galaxy Tab 3 7.0 Android Development] jboyed1999:
Hi I flashed new kernel over v006 and wiped cache and rebooted and all was good. Locked it and it wouldn't unlock. Turned it off and tried to boot into recovery and can't boot into recovery. Tried just letting it boot and it will not boot now :( just sits on galaxy tab 3 logo and I can't get recovery to boot either. Idk if it is a soft brick or a hard brick but will investigate but, it doesn't look good.

EDIT let it sit on the galaxy tab 3 logo for 20 minutes and it booted but still can't get the touchscreen to work or reboot to recovery. Could it be my processor going bad? Touchscreen?

[Galaxy Tab 3 7.0 Android Development] laufersteppenwolf:
Something must've gone terribly wrong there, then. It's running just fine on my device...

If you have adb access, you can enter recovery via "adb reboot recovery". Or simply reboot into DL mode by pressing the button combo for at least 10 sec until the device reboots.
[Galaxy Tab 3 7.0 Android Development] jboyed1999:
I have tried to reboot using buttons but can't get into anything but download mode. I don't think I can get adb access on windows 8.1 I've tried before but will try again. I just hope that it isn't the tablet itself. Do you have any idea on a adb folder/program for windows 8.1.

EDIT. I was finally able to get into recovery. I am install rom again and installing v006 instead of v008 of your kernel again. Thanks

[Galaxy Tab 3 7.0 Android Development] sscsps:
Hey there

I am facing a new problem, my tab randomly gives message saying "sim card removed, please restart" and I have to restart, without restarting, I can't use my tab

This bug comes at any time

I did a quick search about it and found that many people face it on there nexus 5 android 4.4.2, and that is being caused by gps

But not for me, this problem is not because of GPS on my device

It is not an issue in your kernel because I face it on stock kernel too, but I think it can be fixed by kernel

Can it be fixed?

Or can it be fixed with the help of xposed?
[Galaxy Tab 3 7.0 Android Development] HerroYou:
What is your device model #? And did you pick the correct kernel to install?
[Galaxy Tab 3 7.0 Android Development] sscsps:
T211

I used correct kernel

As I said it is not the kernel issue,

I think it can be fixed with some kernel workaround
[Galaxy Tab 3 7.0 Android Development] HerroYou:
I have no idea what the fix is, but the only reason why I asked you what your model number is because when I installed a T211 kernel on my T210R it changed to T211 and it was asking the same message.
[Galaxy Tab 3 7.0 Android Development] andynroid:
That is strange never faced any issues so far 24x7 flashed v08 since the day it was launch :)

Have you guys wiped cache and dalvik after flashing it ?
[Galaxy Tab 3 7.0 Android Development] laufersteppenwolf:
Mind looking back a few posts, what I wrote about reporting bugs? ;)

Hmm, well, it sure can be GPS related, but also something else. But therefore I'd need logs to narrow down the cause ;)
[Galaxy Tab 3 7.0 Android Development] sscsps:
Okay

I will try to provide you logcat, though I would have to keep it running the whole time :(

You will need logcat, right?

[Galaxy Tab 3 7.0 Android Development] Lol Fol:
Please Please please, very much please....

I want you to make it work for 4.1.2, i want it very much for the Jelly bean bro. I loved your work in the 4.4.2 (SM T211), there are no words to be told( damn good buddy). You made serious program change but i liked your work in the Kit kat version. Since some of the root apps don't work( which i wanted to use), so i switched back to the stock rom by flashing a jelly bean and luckily i got it. Now all i want is to make it work for 4.1.2 please. And really a big thanks for the 4.4.2 version of kernel. At first i flashed it by mistake and the tab didn't work at first then i thougth it must be the Jb but then i flashed another kernel then my tab started. And then iread the instructions again in this thread and got to know that it is only for 4.4 version. Hmmmmmmm , i will wait for your reply now.................
[Galaxy Tab 3 7.0 Android Development] andynroid:
Which apps would that be...curious to know ?
[Galaxy Tab 3 7.0 Android Development] Yatskie23:
Im also curious about that apps that does not work on kitkat. I installed some root apps on my kitkat but i dont know if it really works, like gejos enterprises apps. Its already gone from the playstore now. I dont know why, and i still dont know if it works on kitkat, because i have not yet tried it on jb.
[Galaxy Tab 3 7.0 Android Development] sscsps:
I guess he is talking about GameCIH or game killer, both of these don't work on our tab (kk, latest update) (at least not for me), but they both used to work on jb.
[Galaxy Tab 3 7.0 Android Development] Lol Fol:
Actually, GameCIH and (ROEHSOFT) Ram Expander.

It didn't work for me. The main reason that ROEHSOFT didn't work because the partition of the phone is not correct it shows. When i go to my files in KK it doesn't have a proper Partition and doesn't recognize and doesn't work. It shows 0, legacy and i get confused where to put it, but i tried both neither work.................... Please help me..........
[Galaxy Tab 3 7.0 Android Development] laufersteppenwolf:
I'm afraid I don't really understand your question... If you're asking whether or not this kernel is based on official Sammy sources, then yes, it is based on official KK sources.

I'm sorry, but 4.1 uses a different kernel base, and as I am on KK myself, I cannot test it, which means I do not support JB anymore.

[Galaxy Tab 3 7.0 Android Development] laufersteppenwolf:
I honestly don't know what you want me to do... The kernel (or the updater zip to be more precise) doesn't do anything to the init.d folder. It actually does nothing to /system except pushing the modules, that's all.

You've gotta look for the cause somewhere else on your system ;)
