If there is no difference between two why would I spend hours ( if not days) to make same 400+ changes just to say I'm on current one?

I'm sure I can spend time more effective as my last update proves.

More research. More clean up. More ideas.

I think that's more important.
[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
OK guys.

We have over 100 downloads for v0.5.0.

No one has anything to say?

No feedback? No comments? No reports?

Little input will help me.

Gotta know what to look for and what to work on....
[Sprint Samsung Galaxy S 4 Original Android Develop] mikesal57:
Thanks...

I tried your kernel on SACS Rom and no problem installing it..

Why I did it is another story...

My phone was having random shutdowns and it seems that all the galaxyies have had this problem

before I send it back..I used your kernel ..maybe it will reslove it, maybe it wont

worth a try

[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
This is my 3rd galaxy model and I don't have (and didn't have before) any random shutdowns or reboots.

It may be phone specific and not the model.

I had GS2, GS3 and now I'm on GS4 and rest of my family on GS3's.

No one complaints about shut downs or reboots.

2 GS3's running my kernel on stock rooted rom and one is on CM rom.

Hopefully ones you get your phone replaced the shutdowns will be gone......

[Sprint Samsung Galaxy S 4 Original Android Develop] ryan241:
I have a problem with this kernel and WIFI I do believe. I've only tried the last two versions (0.4.0 and 0.5.0). Basically I am trying to download the new 3D Mark update and once it reaches around 40% I get a boot loop. It also happened when I tried using speedtest.

I am going to try something else a little while later. I don't know what though because the KT has all kinds of boot loops on my phone.
[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
Honestly I don't think it's a kernel problem.

1. I did run speed test many times on wifi, 3G and 4G. Never had a reboot or shut down.

2. Combined download count of 4.0 and 5.0 is close to 800. If that would of be kernel problem I think we would of have more reports.

Since this is pretty much first report of WiFi problems I would think there is something else on your phone that might cause it.

Tweaks, edits, rom, scripts.....?
[Sprint Samsung Galaxy S 4 Original Android Develop] ryan241:
I am using the The Blu Kuban rom with nothing extra.
[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
If no other Blu Kuban rom user will chip in with more info I'll try the rom.

I'm on stock MF9 for testing purposes.

Trying not to run any custom roms just to make sure kernel is running on stock.
[Sprint Samsung Galaxy S 4 Original Android Develop] DarkEye45:
v0.5.0 working fine for me.
[Sprint Samsung Galaxy S 4 Original Android Develop] ryan241:
I installed faux123's " mainline no overclocking" kernel. I was able download the app and make a phone call with no issues.
[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
And that info is related to the topic of this thread exactly how?
[Sprint Samsung Galaxy S 4 Original Android Develop] leaderbuilder:
Running fine on MF9 Stock (debloated and slightly modded) for me; as is pretty usual with your work. ;)

I've only tried a few other ROMs (Sac's Triforce Intrinsic..) so far, but they were early releases and I'd go back to stock for full functionality I needed for work.

This weekend I'll run a bunch of the others and see how they go with the new kernel. Just can't spend the time now.

On a side note: what are (if you are) using for kernel tweaks? And what settings do you use?

Thanks again for all the work man!
[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
For all my tweaks I'm using S4 Tweaker and/or kernel tuner.

No permanent settings. Running all across the board so as much as possible will be tested.
[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
Downloaded and installed 3D mark on MF9 stock rom.

No problems.

Uninstalled it.

Installed blu kuban rom.

Flashed 5.0 kernel over it.

Downloaded and intalled 3D Mark again.

Still no problems.
[Sprint Samsung Galaxy S 4 Original Android Develop] ryan241:
What are you talking about? :confused: I was simply letting you know that another kernel appeared to work on my phone.
[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
I'm asking users to report how this kernel performs.

If you had problems with this kernel and would of report that certain things did not work with my kernel and did work with other one I would ot understand that.

But all you did as saying that faux123 kernel works. Nothing about any problems with this kernel.

Thus I asked you what the info about faux's kernel has to do with the topic of this thread.
[Sprint Samsung Galaxy S 4 Original Android Develop] Koserman:
Been running since you released it! Other than having an issue of it not turning back on (stuck on bootloop) after running it for the majority of the day, everything's been great! I have no clue what caused that strange episode (Negalite ROM) so I bet it was a fluke). Very responsive, good battery life and I love it! Thank you for the kernel kind sir! Hope your computer issues are fairing well.

***Rebooted and was stuck at bootloop (I don't know if I'm using the terminology correctly, it was stuck at the graphics part) so I tried flashing a different kernel and wiping the cache/dalvik cache and the same thing happened. I believe it might be tied to Negalite's performance script but I'm definitely not knowledgeable enough to determine this. I'm going to try flashing his ROM with the stock kernel and then flashing yours over it to hopefully prevent this problem. Thanks again
[Sprint Samsung Galaxy S 4 Original Android Develop] daniel4653:
I came in too late. I'm running blu Kuban and don't have any random reboots happening at all. Ran v4.0 for two days with no problem. Since installing v5.0 earlier today I've had no problems either.

Edit: just ran 3D mark twice and it didn't lock up or slow down the phone at all. Downloaded the 150 mb file with easy and obviously KT installed.

I'm having no issues with 0.5.0. I don't believe in adding to a kernel just to add to it, so I've got no suggestions or complaints. While I'm hopelessly addicted to flashing/breaking my phones, add what you want Agat. I'm quite happy with what's being presented here as is. It works, and does it very well.
[Sprint Samsung Galaxy S 4 Original Android Develop] Doctor_XXX:
I guess this means you got your PC back?

As I posted back a page or two (#918) v0.5.0 is running great over here. Stock MF9 with Hotspot mod & that's about it. Keep up the good work! (Let me know if you need more tests done on the next version...)
[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
Nope.

I don't have my PC back yet.

Should be in by weekend. Hopefully.

I did build the last one on a server I did set up with help of dev's from DreamTeam.

it was almost ready when I took my pc to bestbuy.

We were running some test on native ExFat support.

Everything was working except when trying to unmount ExFat card from settings menu phone was freezing.

So Talustus from dream team did last edits and i was able to move my git source to server and build the 5.0
[Sprint Samsung Galaxy S 4 Original Android Develop] Koserman:

I did a clean install of everything and it works flawlessly! 5.0 on WondeRom r52.

Finally my exFat 64gb sdcard works !!!

Tried in vain to get it to work on all previous versions of this kernel and always got the sdcard safe to remove message. Even went back to stock and tried that. Everyone else seemed to have no problems with their card, so it was something on my end I think.

Getting the native support built in took care of it though. Still makes me wonder why. I changed nothing. Just flashed v5 and presto, it works.
[Sprint Samsung Galaxy S 4 Original Android Develop] Grommish:
Did you clear cache and dalvik? Syncing is a ROM function I believe, not kernel. But since dalvik is built on the kernel you should always clear cache and dalvik when changing kernels.
[Sprint Samsung Galaxy S 4 Original Android Develop] zackandethan:
Agat, running 5.0 since it's release with TriForce 3.1 and still no issues on my side . Tried them all and my phone seems to run best on your work .
[Sprint Samsung Galaxy S 4 Original Android Develop] Androidious:
Have you ever tried running AnTuTu with this kernel? It seems to run great for me but as soon as I try to get a benchmark from AnT it will freeze the phone with a black screen requiring a battery pull every time about when it gets to testing the GPU. Weird.
[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
Antutu doesn't work when you OC.

I have tried Antutu on stock frequencies and it runns normaly.

As soon as I OC antutu fails but it never did freeze the phone.

It just fails and stop. That's it.

I think the problem is antutu and not the kernel because if you go to system/device info tab antutu reports phone as exynos 1.6 quad core and not as qualcom 1.9 quad core.

I might be wrong tho...
[Sprint Samsung Galaxy S 4 Original Android Develop] roadrunnrr:
I've been having trouble with agat kernels for ever. .. today I flashed 5.0 and tried using kernel tuner and sure enough my phone turned off and landed in a boot loop. Then I pulled the battery and it turned on. Tried it again with kernel tuner but as soon as I tap on cpu it'll reboot. The same procedure...pulled battery turned it back on and used s4 tweaker to set cpu everything works great. All functions of kernel tuner work for me exept cpu adjustments for that I have to use s4 tweaker. I am pretty sure that has been my problem all along. Kernel works amazin thank you for the hard work.
[Sprint Samsung Galaxy S 4 Original Android Develop] Fuze_yo:
Just wanted to say thanks.. been running this kernel w no issues ... i just upgraded to the latest. I had been on v0.1.8 for a while.

[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
I have somewhat good news... I guess.....

Finally got my laptop back. That's the good part.

Bad part is they did somehow break my grub boot part and pc won't boot to linux only to windows.

So it looks like I'll have to install linux from scratch.... :(

That's the bad part...

Will take me about day or two.

And than I'll be back and ready for new stuff...

[Sprint Samsung Galaxy S 4 Original Android Develop] Androidious:
Yah man, I wish I knew all that Linux stuff. Men maybe someday lol
[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
Quick update.

Just installed Linux and first thing I did is downloading MDL and MF9 source from Samsung site.

Did run diff on it and still not a single line difference between those two.

At least not in kernel source.

Either all the edits and changes between MDL and MF9 are in OS or samsung still didn't upload correct kernel source for MF9.

I don't know why other kernel dev's will say they updated to MF9 source or call my kernel based on old source if there are no

differences between MDL and MF9.

I'll start restoring all my back ups now and hope to be finish it tomorrow.....

Too much to restore... :D

Can we have some one do a help/tutorial thread using this kernel like KT? I know a lot is trial by error when it comes to kernel settings but searching across the threads for setups is tedious. I'm not trying to be lazy. Just a suggestion.
[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
I'm not sure I understand what kind of tutorial you need.

There are no universal settings. Each phone is different. Each user is different. And every one has his/hers own expectations from kernel/os.

Some looking for longer battery life. Some need more performance.

With all governors, schedulers, frequencies and voltage option there are few thousand possible combinations.

I think you should be more specific at what you looking for and what are your expectation and may be some one can give you more info.

This kernel doesn't have or need a paid control app attached/suggested to it so there are no tutorials how to use different options of the app.

All other settings will be defined by your usage and needs.
[Sprint Samsung Galaxy S 4 Original Android Develop] typxyt:
I didn't mean to insinuate that the kernel needed any paid app. Sorry if that came across.

I was meaning a help/tutorial thread where users can share their settings based on their needs to the agat community. The OP could update the first post or two with examples of the setups for UC/OC, performance, balance, and battery.

Honestly, I don't know what each kernel setting does and I have been using the kernel as it comes without tweaking anything. It would be beneficial to me to have people share in a thread their experience with the kernel. By having a separate thread, this thread can stay clean and only about development.

Just a suggestion. Maybe the community doesn't need a thread like that. I just thought it would be nice.
[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
As I mentioned above there are no universal settings that would work for every one.

Samsung never made 2 phones same .. ;)

What works good for some might not work for others.

For example I had to add a script to kernel to cap boot frequencies at stock because some of the phones couldn't handle OC and were going into boot loops.

I think most of users got to their daily settings with experiments.

Combining different governors with schedulers, playing with frequencies and voltage to find that optimum they were looking for.

I know there are many options available but the first question would be: "What are you looking for?"

For better battery life is one set of rules.

Better performance another one.

etc...

Don't forget there are way too many possible setting combinations to make a tutorial and/or a guideline and on top of it we have that big unknown "Samsung"...:eek:

So, I'm sure if you outline your expectations or needs someone will help you with setting suggestions as a start point.
[Sprint Samsung Galaxy S 4 Original Android Develop] Grommish:
You just install S4 Tweaker and test the CPU settings. Other than that, Governor is the only other setting you'd might want to change.

You flash, you wipe cache and dalvik, reboot.
[Sprint Samsung Galaxy S 4 Original Android Develop] typxyt:
I understand. Flash and play. I was only thinking it would be helpful to share settings knowing every phone is different. Moving on....

I don't know if this is kernel related or not but some of the applications I use have recently been updated taking this vulnerability into consideration; Application-level workaround for the Android platform's PRNG security vulnerability: http://android-developers.blogspot.com/2013/08/some-securerandom-thoughts.html

The updated applications either crash, or load and do not work due to "Unable to open /dev/urandom".

I did freeze all apps with KNOX in names ( I think there were 3 of them).

And I'm running crawrj's hot spot mode.

Those are the only changes and edits to stock MF9.

And I didn't root it or applied/flashed rooted rom.

I did flash fully stock MDL. Let it upgrade to MF9.

Flashed my kernel vial odin.

Since kerne has auto root built in it did root my phone on reboot.

After that I flashed DREAM_TWRP tar via ODIN as well.

Then I flashed my kernel zip to get all appropriate modules.

That's it.

Hope this helps.

[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
what kind of videos you have problems with?

I did film and play videos and youtube.

Both work here.
[Sprint Samsung Galaxy S 4 Original Android Develop] Grommish:
Nothing wrong with video here either.

When you flashed Agat kernel, you cleared Dalvik and cache?

KToonz kernel I've personally had issues with in the past, others use it as a daily without issue. You may want to backup and wipe, start with MDL or MF9 ODIN, reflash TWRP/CWM (Agat uses TWRP, which I'm fine with) and flash the kernel and let TWRP install Super SU for ya.

SMS Backup and Titanium Backup are available on the store.

Yea, I tried that one and the one off of teamuscellular and it did break my sd card after I booted as well. Plus it would only boot once to that recovery and then it would revert back to the stock recovery. The twrp is the only one that would stay.

EDIT: Decided to try the OUDHS 1.0.3.1 from teamuscellular.com and went fine this time. Then tried to flash this kernel:

Installing:

fnding update package

opening update package

installing update

SuperSu installer zip

mounting /system and rootfs

removing old files

creating space

extracting files

restoring files

setting permissions

set_perm: some changes failed

e:error in /.........zip

(status 7)

installation aborted
[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
This list of steps is different of what I see on my phone when flashing kernel.

All you have to see there is mounting system, extracting system, flashing kernel.

There is noting else in updater script. At least is should not be.

Please specify what zip file did you donwload so I can check the script in it.
[Sprint Samsung Galaxy S 4 Original Android Develop] holmesm:
I used the zip from post #62
[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
That zip is not sprint phones.

It's for USCC and updater script has been provided to me as working script for that phone.

So, if you on uscc it should work but if you have a Sprint phone you flashed wrong zip.

You should us zip files from OP.

Last few days I was trying to get to the bottom of 64 Gb sd card support in updated versions of the kernel.

I think I'll leave it as for now till we know more and move ahead with development and additions.

Fast charge is one of them but wasn't a priority for me.

If it's needed and wanted I'll add it.

Really like this kernel (0.1.4), can't wait till you add undervolting and I'm already underclocked (1.45 Ghz) I think). Getting through a full day of heavy use without charging would be awesome on a phone this powerful. Would love to hear the 'features' you hope to implement in the future. Thanks again.
[Sprint Samsung Galaxy S 4 Original Android Develop] Pheonix28:
Would it be possible to integrate some of your updates into your 0.1.2 so that those of us with the 64GB cards can take advantage of these features as well? Or would that be too much work?
[Sprint Samsung Galaxy S 4 Original Android Develop] agat63:
As you correctly stated only some of the features can be added to 1.4 and keep 64GB card support.

I can't do any more main stream updates to kernel source. So Linux version 3.4.4 is as high as I can go.

3.4.5 patch does change kernel tags and stock modules do not work with kernel.

Exfat modules are propreitary and we don't have source for them so I can't compile them with kernel. Only modules built with kernel will work on any version 3.4.5 and higher.

All other updates that are not depending on higher linux versions can be intergrated into v0.1.4 and I'll try to make 2 versions of kernel whenever it's possible.
[Sprint Samsung Galaxy S 4 Original Android Develop] dbpaddler:
Fat32 here too. So I'll raise my hand for fast charging.
