Try 2 things for me set cpu governor to performance and gpu to performance on a fresh boot and tell me the scores then... also I use device control and it never freezes on me. Kernel aduitor don't stick the settings for me for some reason thus using device control. Oh and if u notice the 3d on the gpu on performance the graphics look real nice
[Galaxy Tab 4 Original Android Development] keikari:
With performance governors I got 18371, 3D:326, UX:5942, CPU: 8947, RAM: 3156.

When i set device control to restore settings on boot tab chrases about in 30s. Also crashed few times in middle of the test.
[Galaxy Tab 4 Original Android Development] rcolitz:
This is my results with beastkernel v2.
[Galaxy Tab 4 Original Android Development] rcolitz:
There you go with the screen shot of Kernel Tuner.
[Galaxy Tab 4 Original Android Development] thelous:
whars max ghz you can get out of it? and how overclocking affects battery heat and life?
[Galaxy Tab 4 Original Android Development] rcolitz:
that's the only thing that worries me because there's no cooling fan and I am not running my tablet with it taken apart. I will run it at 2002mhz and so far it just drains the battery and I am not seeing anything bad happen. I run it at the maximum because I play a specific game on it and it seems to run better running at the maximum than running it in a normal mode like 1066mhz it doesn't freeze when run the game at max but at normal the game tends to freeze up.
[Galaxy Tab 4 Original Android Development] doctazz:
I'm getting 1690 as my max CPU speed. Using the kernel with the Acheron 2.3.5 ROM, and Device Control. Guess I'll give Kernel Tuner a try and see if I can get 2002. My tab 4 can now play 60 Hz 720p videos from YouTube fairly smoothly, with very little video stuttering. Especially useful when watching live streams.
[Galaxy Tab 4 Original Android Development] rcolitz:
The Beast Kernel v2 will allow you to get the processor up to 2002MHZ. I just ran a benchmark oñ the latest kernel release of the Best Kernel please see attached.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
I can easily increase max clock speed higher than 2002 mhz but I would like to see fluent freq steps I'm not liking how it jumps from 1066 straight to 1690 or 2002 I would like it if it would be 1066,1248,1482,1690,2002 but I can't figure out why the clock won't just add my steps
[Galaxy Tab 4 Original Android Development] jdoggawesomex900:
Can you give link to this kernel please? All i find is beast kernel for samsung galaxy star.
[Galaxy Tab 4 Original Android Development] rcolitz:
Well beany23 is the original programmer for the beastkernel and I have them saved on my Dropbox account and I am using the beastkernel V2 right now on my SM-T230NU. . Somewhere in the previous posts in this thread is the download link to those two kernels. If you can't find them I don't know what the policy is for me to provide a download link to my Dropbox account because I am not the original programmer for that kernel so I have no rights to the program. But if it's okay I can post the link to my Dropbox account to where those files are stored.
[Galaxy Tab 4 Original Android Development] mike2nl:
Hi beany and rcolitz,

i am back after a long time because some privtae issues that has to be solved and all is now green.

I had read the last five pages and i asking myself how is the state of this very fine kernel?

Some new things that has to be tested? I have a spare t230 for tests right now... so lets go on?
[Galaxy Tab 4 Original Android Development] LordGone:
I have a sm-t230nu, and have been unable to use any of the modified Kernels listed in this thread or anywhere else I can find. I have tried flashing with odin v3.12, or through the latest TWRP. 3.0.2.0, along with older versions of these (odin 3.07 and TWRP 2.8) and still no success.

I have tried CTXz v 1-4, beastkernel 1 and 2, Adamskernel v 1.1 and Nuki 1.1. The farthest I can get it is a minute or so into the GUI before a full freeze requiring a hard reset, though more than 3/4 of the time I get a system freeze on the samsung logo.

I have tried cache and Dalvik wipes both with odin and without, and I have flashes these kernels on the stock rom as well as Prism V4/S, to mostly the same results. Is there some obvious step or troubleshooting process I'm missing? I'd love to be able to keep this tablet, but that's tough if i'm not able to do this. Please keep in mind that although I am trying, I have almost no idea what I'm doing.
[Galaxy Tab 4 Original Android Development] trentenmarschel:
[MENTION=6332061]beany23[/MENTION] Did you get this kernal to work with the ir blaster? Also I am now having issues with my galaxy tab 4 Sm-t230nu. I am getting ready to wipe it and start over, so If you have a stable kernal that works well, I would like to give it a try. As of now, I am having issues updating apps, and doing a full nandroid backup, every time I try to update any app, it says insufficient storage. If I go to do a full backup via twrp recovery, it acts like it is doing the backup fine, and at the end it says finished. When I go to find the backup with any file browser, it is not there at all. I think I am going to restore to an old rom backup and then flash a new kernel.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
It's either beas kernel v1 or v2 lol I can't remember which exactly. And to anybody reading this I'm still building for the tab 4 I just trying to fix my Linux os..the screen goes red then shuts off. As soon as that's fixed I'll be throwing another kernel out :)
[Galaxy Tab 4 Original Android Development] trentenmarschel:
Can you point me to the link to download the most stable OC kernel that you have that supports the Ir blaster? Thanks Beany.

I am still trying to backup my current build. The SD card is extremely corrupted. I put the micro SD card into my laptop and went to format it with mini tools partition wizard, and every time I formatted it, It would revert back to how it was before I formatted it. I even manually deleted everything on the SD card with windows and the next time I plugged the SD card back in, Everything was there again. Never had that happen before.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Give this one a go if it's not it check v2 in downloads section of my mediafire

---------- Post added at 06:43 PM ---------- Previous post was at 06:41 PM ----------

Give this one a go....http://www.mediafire.com/file/5ieb23pdm2d17n4/BeastKernelv3.zip. if that's not it check the downloads section in my mediafire
[Galaxy Tab 4 Original Android Development] The_Anomalist:
So I'm back! And wiser than before lol.. I am building the kernel with linaro and adding a hotplugg, 5 governers(which don't seem to show up in kernel adiutor yet!), and about the clock..... I'm gonna have to start with the max at 1586 it seemed to be the most stable frequency on some of my recent builds so that's what I'll stick with and the gpu stuff will have to hold off a bit since we need a smoother ui rather than a laggy ui and better graphics performance lol
[Galaxy Tab 4 Original Android Development] trentenmarschel:
Thanks so much [MENTION=6332061]beany23[/MENTION], I got a new SD card for my tablet and re-flashed the Prisim barebones rom and the ir blaster support files, and then I flashed your kernel that supports IR blaster. Now everything is working including the IR blaster support. Now I just need to finish restoring all my files and apps. It looks weird when it is plain stock with no apps.
[Galaxy Tab 4 Original Android Development] mike2nl:
Short Question beany...

i know v3 kernel has ir support now and i have never tested v2....

- So is that the only change in v3?

- Can i use it in my sm-t230 who has no ir blaster? (i think yeah...)

Hope you can give me a short hint...
[Galaxy Tab 4 Original Android Development] The_Anomalist:
I have a new build I'm going to post it consists of fast charge, overclock to 1794,ir blaster works, and hotplug, underclocked down to 156,no governers yet since they are messed up in kconfig.

Gpu is still stock, but I might work on that today also I'm working on the cpu on its voltages and freq steps.

---------- Post added at 08:04 PM ---------- Previous post was at 08:03 PM ----------

U should be able too since the only difference is the ir blaster.
[Galaxy Tab 4 Original Android Development] trentenmarschel:
oc to 1794? I am almost certain the kernel you pointed me to that I just installed goes to 2000. I just had cpu monitor going and it was maxing at 2000mhz. I will double check.

Update: Yea here is a screenshot.

[IMG="screenshot"]http://i.imgur.com/adkSNyu.png[/IMG]
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Close

I'm close to finishing the cpu frequency problem...it just freezes

http://iob.imgur.com/uYGg/lvIcrtdAOy

---------- Post added at 10:01 PM ---------- Previous post was at 09:59 PM ----------

Lol I didn't post any builds yet 1794 is still what the build will have once it uploaded l, also check the link I posted
[Galaxy Tab 4 Original Android Development] trentenmarschel:
It was the kernel in this link that you told me to use. http://www.mediafire.com/file/5ieb23pdm2d17n4/BeastKernelv3.zip

In this post.

[IMG="post"]http://i.imgur.com/BTEsXpt.jpg[/IMG]

I thought this was your kernel? Either way, it seems to be oc to 2002mhz. So is this build stable? Do I need to underclock it to a lower speed?
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Ya that's one of mine as well but what I'm saying is the build that I'll be posting later is only oced to 1794. And yes it pretty stable on 2002
[Galaxy Tab 4 Original Android Development] trentenmarschel:
Okay, thanks. I'll probably need it. For some reason I'm having the same issues as before when I did this a couple years ago. The cpu frequency steps get stuck on max.
[Galaxy Tab 4 Original Android Development] trentenmarschel:
Well I got it to quit getting stuck at 2002Mhz. I had Device Control, Kernel Adiutor, Rom Toolbox Pro, and 3c toolbox all trying to control the Cpu. So I used SD Maid to disable the auto start on all of them except the Device control, and it seems to work now. It still shoots up to 2002Mhz every time I touch it and stays there for like 15 seconds. At boot it stays maxed out for about a minute.

Thanks again for adding support for IR blaster. It's nice to have the option to have all the sensors and stuff working.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
It's no problem I needed the ir blaster so it was kinda necessary lol and the reason it stays at 2002 at boot is because of the way the plls are running, there isnt another high frequency to jump from so it shoots straight to max which in turn locks the frequency in place for a bit. Most devices can accommodate for that but this device has issues with it that's y I'm trying to add at least 1 other high frequency

So it at least doesn't stick at max or have trouble ramping through the frequencies.
[Galaxy Tab 4 Original Android Development] trentenmarschel:
Well, Since I flashed rom and kernel, I haven't had any issues yet with the OC. Once I fixed the other apps trying to control the speed, It seems to go through all the steps when idling. If I touch it or do anything it automatically goes to max. But I think every kernel I've had on it including the original oc kernal have done that, so I don't think it a problem. I haven't done any stability testing, but I will do that next when I have some more time. (Last week of school then finals next week)
[Galaxy Tab 4 Original Android Development] trentenmarschel:
Okay, So I have had that kernel flashed for a few days, and I've noticed a couple random crashes where it reboots when it was laying idle.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
I was curious about that specific kernel anyway so I flashed it last night and so far I'm not liking anything about it....I personally use the standard beastkerne since I've not had any issues with it

---------- Post added at 03:31 PM ---------- Previous post was at 03:28 PM ----------

Guys I was successfully able to overclock the video-processing-unit and as far as I can see there is a good jump in picture quality and smoothness of the ui!
[Galaxy Tab 4 Original Android Development] SilverLyricDragon:
Similar.

I've only noticed a few issues recently while watching YouTube. Sometimes I'd be watching a video, the audio would glitch out, screen would become unresponsive before it totally crashed.

Sometimes my WiFi would randomly drop for a seco then come back, and a few other things.

Although, I cannot 100% say it's the kernel's fault.
[Galaxy Tab 4 Original Android Development] zMILWAUKEE:
Any progress on the new kernel build. Like the tablet but its extremely laggy. Can't even play clash of clans at all. The cpu on this tablet is not the issue, it's the bad gpu and the poor resource management, one of the reasons I tend to stay away from Samsung, it's over priced junk packed full of bloat ware.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
I'm trying but I don't know what happened....I changed something and it doesn't boot and I never committed anything so I'm in the dark:( I had a couple new features added the best one being fast charge. I was also very close to getting voltage control but now I'm stuck. If I don't figured it out within a couple days I'm just gonna restart.
[Galaxy Tab 4 Original Android Development] SilverLyricDragon:
The most recent build you've posted works perfectly for me.

Only issue is that it loves sticking and staying at 2002 MHz.

Other than that, a week or so after I flashed it YouTube was impossible to reliably watch. That seems to have sorted itself out, however.

Great work, though. It's fairly stable and has yet to just crap out on me, although that could just be me.
[Galaxy Tab 4 Original Android Development] trentenmarschel:
Hows it going beany? I've started to have more issues with the os in general. I don't think it has anything to do with your kernel, but I am unable to install some apps even though I have almost 2gb of free internal memory. Trying to install 8 ball pool by miniclip. It's only like 32mb, but every time I try to install it both in the play store and with the apk alone, it fails to install. Trying to reset my play store to see if that helps.
[Galaxy Tab 4 Original Android Development] SilverLyricDragon:
The Play store refuses to install some apps if it has <500 MB available.

If you have an SD card, remove it and try installing it again.

They clearing the Play store data and cache. Might help.
[Galaxy Tab 4 Original Android Development] trentenmarschel:
Didn't think of removing the sd card, but trying it now. I have plenty of space on both internal and external I'll upload screens if it fails again.

Well Thanks a lot it seemed to work with the SD card removed. Wonder if it's trying to install to ext sd by default.

Well it installed, but crashes instantly.

[IMG="screenshot"]http://i.imgur.com/lElTIgA.png[/IMG]

I might start a new thread on it if I can't figure it out. I might try to wipe the rom and do a recovery again. I just did this a few weeks ago.
[Galaxy Tab 4 Original Android Development] SilverLyricDragon:
I read up on it and there is apparently a file that just loves to get corrupted.

One fix is to remove the SD card, install the app, and reinsert the SD card. Annoying, but what can you do.

Or, it tries to put some of the data on the SD card, fails, then says it cannot install, as you suggested.
[Galaxy Tab 4 Original Android Development] ZoneDev:
Is this works for t230 version?

Im just asking if this kernel works for t230 cause i want to run my tablet with medium ghrapics...
[Galaxy Tab 4 Original Android Development] SilverLyricDragon:
We have this amazing thing called reading the topic.

Aka, the thing that says "[KERNEL] CPU Tweaks for Tab 4 *T230* / T230NU with Overclocking"
[Galaxy Tab 4 Original Android Development] trentenmarschel:
Okay, I have it working. Like you said remove SD, Install, Insert SD, Restart and it works most of the time. It crashes if I switch login types between Facebook, Google, or Miniclip. For some reason that makes me think it has something to do with a google service and not the kernel. But thanks again, I wouldn't have thought to remove the SD card in the first place. Also Kernel is working good still and it scales through all the CPU frequency steps alright. It's real jumpy, but eventually settles down around 156-624 Mhz.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
here is my update on frequencies..... http://imgur.com/a/h4l0Q
[Galaxy Tab 4 Original Android Development] zMILWAUKEE:
Beany great work so far, and i feel like a bum asking after you basicaly had to start all over, but hows the gpu freq getting along. as soon as you get it ready im here to test anything you are willing to work on with this tablet.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Well I'm glad u brought it up.. I actual got the overclock step added with no issues on the gpu (832mhz) btw. I also got more gpu steps to show up (my new frequency steps) the only thing is the way the gpu is ran.. for e.g. pll1_624 runs the Cpu speeds that range from 624 to 312, now the gpu runs on the same rail as the lower clocks on the Cpu but the problem is that when the frequency is changed on the gpu it wipes out the 624 and 312 step on the Cpu.. so now I've been tinkering around with new rails they run on to see if it helps with the clock wiping and or why it lags. If I can place them on a new rail it might fix the entire issue I've been havin with the whole tab in general... figures crossed lol since writing this I had a few more ideas pop up. Let's see what they do
[Galaxy Tab 4 Original Android Development] zMILWAUKEE:
Good luck man, and thank you for all the hard the work.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Thanks, also to anyone reading this...I know some of u have been here since I first put a build out and I want u guys to understand that this processer I'm working with is unlike any other, it's not like a snapdragon porting to snapdragon or enxyos porting to enxyos, so porting things is very difficult with this cpu. The code is setup way different then on any device I've worked with...so please give me some time and I promise I'll make up for it with... BEAST KERNEL!
[Galaxy Tab 4 Original Android Development] doctazz:
No problem! I have moved on to a new main tablet. My tab 4's screen has separated itself quite a bit from the casing. The touchscreen still works fine, but the separation is most likely due to the extra heat generated from overclocking. The screen itself is sort of sticking out in a concave shape. Otherwise, I haven't noticed any degradation in overall performance. If anyone has any ideas for fixing the separation, I'd love some tips. (Of course, I'll check out YouTube for that.) I was hoping to turn the tab 4 back onto the original nook based rom it came with, so I could use guest mode and leave it in the living room for guests to use. I don't think that's such a hot idea anymore.
[Galaxy Tab 4 Original Android Development] zMILWAUKEE:
if you google replacement glass for the tab4 you can find sites to buy that adhesive to repair the screen. A little heat from a blowdryer and remove the old gunk and a little pressure with new adhesive down your done maybe half an hour of work. that adhesive is anywhere from 9.99 US to 20. Good luck.
[Galaxy Tab 4 Original Android Development] shiyaz ashraf:
please help me

i successfully installed your kernel and I used it for many days.but now iam facing a problem,my tab just turned off automatically and now it automatically restarts.it shows the Samsung logo and again restarts.pls help me.i cant boot into the twrp recovery or the recovery mode.
[Galaxy Tab 4 Original Android Development] SilverLyricDragon:
You likely soft bricked the device, or hard bricked it.

Did you follow the steps exactly?
[Galaxy Tab 4 Original Android Development] trentenmarschel:
Agreed, I would try to flash the ROM back on with Odin, and then reinstall TWRP and recover.
[Galaxy Tab 4 Original Android Development] mkhtfld76:
You dont have a TWRP back up? If you can boot into recovery you can just restore it from there. No need to odin.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Hey guys haven't been on in a good while been going through some life changes so been to caught up lately. I just installed Linux mint 18.1 and am gonna start building again this weekend.
[Galaxy Tab 4 Original Android Development] hanzaz:
hello there dear friends i have a questions and i hope to get an answers for them (tab 4 10.1)

can tab 4 play full HD movies ?

can i flash lineage rom on it?

is it slow ?

i found an old device for 100 usd it it a fear price or note?
[Galaxy Tab 4 Original Android Development] CTXCI:
So do I need to download an Overclock app from the Play Store after installing this? Or is it already pre-configured?
[Galaxy Tab 4 Original Android Development] doctazz:
It's preconfigured to overclock at the highest speed possible. You will need an app like Kernel Adiutor to control the governor, and range of CPU speeds you want to use.
[Galaxy Tab 4 Original Android Development] sukhman12:
I have installed it in my tab 4 t231 but it doesnot have sim card access so tell me how i restore to stock
[Galaxy Tab 4 Original Android Development] keikari:
Serach about "Odin" with it you can install samsung official firmwares. Or you can try to find stock kernel from this forum if someone has happened to post one and flash it in TWRP.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Yo yo

Currently as I type I'm building a kernel, now what features would you guys like implemented I know I asked before but no one gave me concrete ideas.....so what shall be added?
[Galaxy Tab 4 Original Android Development] The_Anomalist:
I build for the smt230nu, the smt231 is 3g which uses a different set of config files in order to have service. Once I post another build (which has been a good while) I'll see about making the same kernel work with service as well that way each version(s) is able to do what it was designated for wifi only, 3g etc etc.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Wow

So apparently guys I've been accused of stealing credit from [MENTION=6584695]CTXz[/MENTION] on this kernel. This website here (the name explains what's going on) https://androidforums.com/threads/zte-zmax-pro-official-root-discussion.1110550/page-129 they saying I never compiled a kernel for u guys so If someone would be kind enough to prove them wrong that would be awesome.
[Galaxy Tab 4 Original Android Development] Ayepocalypse:
Using the 230NU tab with the 2.1 kernel since it is the most stable. 2.2 is laggy and the CPU usage was high when doing nothing. The min and max clocks also kept changing to 1.444ghz for both. After a couple of minutes it somehow ran smooth but after every reboot it does it and gets annoying so I got 2.1 again.

Btw thanks OP for the overclock. My tablet feels a lot more snappier I sometimes think it knows what I'm going to press next and does it :p
[Galaxy Tab 4 Original Android Development] doctazz:
Settled on 2.1 for now. :)

I overclock for 3d games only. Otherwise my settings are 312 (?) Min, 1066 Max @ interactive. If I OC running video (esp. CPU intensive Flash) for more than a half hour, the tab's battery runs at 40c! That's too hot for me. Then I'd have to turn the tab off for a half hour and take it off my nook case to cool (if possible). I use Kernel Tools to change the frequency and governor.
[Galaxy Tab 4 Original Android Development] CTXz:
Scratch the thing with alternative or 2.3. Seems like 2.1 is byfar the most stable
[Galaxy Tab 4 Original Android Development] -=AsteriX=-:
Do you have ideas to add OTG in 230/231 kernel, some of devises have working OTG, so i think its real may be even not difficult
