[Galaxy S 4 Mini Android Development] F4k:
In this case I'm afraid I have to agree with [MENTION=4551463]leripe[/MENTION], if you think that it's the kernel then you should stick with something that works with your device.

Also you're using too many xposed modules that can affect system stability and in this case I think there's nothing wrong with the kernel, no body else reported something similar, so that make me think that there is nothing wrong with the kernel but your device.

However, some of your applications or mods, could conflict with the kernel, remember that it have too many features when compared with stock cm kernel, so you could try to test this kernel, without any add-ons or mods.
[Galaxy S 4 Mini Android Development] iFlasher:
Ok, maybe yes it can be a problem with my device or apps (I do now a clean install again without xposed and apps to see what happens).

But if the problem persist maybe it can be a problem with the kernel and some of the tweaks that this have (A similar problem happens when I had the Xperia Play with a custom kernel, and I reported this and after some testing with the Dev, he found that reboots are caused by a tweak), because in the stock kernel I don't have these problems and I don't know if I can flash stock CM kernel to CarbonROM.

So I report what happens in a clean install again...

Thanks ;)

Ok, I do a clean install of Carbon Rom(absolutely wiped all and retired sdcard), without The google apps and any extra app or mod, all wiped, and with only The stock apps, while I browsing with The stock browser I had a new random reboot. Now what? I really like f4k kernel but those problem are annoying and The bar of this is that I lose my app data after a random reboot... I think The only thing that I can do is use The stock kernel with cyanogenmod, because dont know if stock CM kernel work with CarbonRom.
[Galaxy S 4 Mini Android Development] F4k:
It should work, take boot.img and modules from cm ROM and replace on kernel's zip file.

Sent from my GT-I9190
[Galaxy S 4 Mini Android Development] iFlasher:
It work fine and without random reboots in the latest 2 hours. I think I keep with it, maybe in the future you can fix those problems with the kernel.

Thanks again man ;)
[Galaxy S 4 Mini Android Development] mielletseed:
I have had random reboots to on i9192 with f4k kernel and some xposed modules too. Thought it was caused by the new ROM. Will try with cm kernel now and report later

[MENTION=3261191]F4k[/MENTION],

Could you make a JB flavour of 1.5.0 kernel for those of us who don't like what KitKat is doing with their phones, but would still like access to things like F2FS?
[Galaxy S 4 Mini Android Development] Aronuser:
you can disable the standart undervolting settings to try to prevent it, (there is standart undervolting active) tick set on boot too.

worked for me
[Galaxy S 4 Mini Android Development] erenkeros:
Hi people! I wanted to tell you how i worked my problem out. If you suffer minimum or maximum frequency stucking, governor problems or any kind you think is related to F4K's kernel, I advice you to flash the kernel twice and reboot it. I know it looks silly but it worked for me and all other my previous problems. Because this kernel is near perfect!!!
[Galaxy S 4 Mini Android Development] luisbraz:
Flash kernel, reboot phone, shut down, enter in recovery and flash again?

Or just enter recovery, flash the kernel twice and reboot?

It's working with all the governors? I don't have that bug when using ondemand, but with others the min. freq. problem appears.

Thanks.
[Galaxy S 4 Mini Android Development] erenkeros:
actually i tried both at the same time and it was successful for me but i've read somewhere about it and it was the second one. I mean enter the recovery and flash twice in a row and then reboot.

Yeah ondemand is pretty stable but some other ones, which are in developing, i mean smartmax, smartassv2, smartassh3.. I have been using smartmax and having problems. Now it's all good. Smartmax - sioplus / 384 - 1350.

EDIT: when i use 'ondemand', my phone gets really hot :)
[Galaxy S 4 Mini Android Development] Phenom2122:
Apologies if this has already been mentioned. Since the latest Carbon I have been unable to make a tethered internet connection to my computer. Only when I tried the latest Slim with f4ktion 1.5.0 did I realise it wasn't working there either. After switching to 1.4.5 I can now tether internet to my computer.
[Galaxy S 4 Mini Android Development] F4k:
1.5.0 JB variant it's incoming, I didn't tested yet 'cause I need to complete a battery test cycle on my device.
[Galaxy S 4 Mini Android Development] jamus28:
Awesome. I tested a build with about 80% of your commits. No problems so far.
[Galaxy S 4 Mini Android Development] Oijkn:
Hi F4k,

Thank you for your great Kernel ! Before i was on version 1.4.5 and all works very well but since i have updated with your last version 1.5 my wifi don't work anymore (i can't activate it...). I flashed again the version 1.4.5 and now my wifi is back !

I hope you can fix it :)

Best regards.
[Galaxy S 4 Mini Android Development] leripe:
It's nice to on every page and day on this thread that wifi stops working with 1.5.0 :D It's a god damn known issue and if just people bothered to read even the latest posts, but nope..
[Galaxy S 4 Mini Android Development] F4k:
Updated JB variants to 1.5.0, F2FS support it's included as well, however CM 10.2 doesn't support this file system.

You'll need to add mkfs.f2fs, fsck.f2fs, fibmap.f2fs and f2fstat to bin folder on your CM 10.2 ROM zip file, plus you have to edit updater-script file if you want /system formatted as F2FS as I described in this thread and adding this additional line before

symlink("../xbin/su", "/system/bin/su");

symlink("../bin/fsck.f2fs", "/system/bin/dump.f2fs");

With that said, this probably will be my latest build for JB variants :)
[Galaxy S 4 Mini Android Development] impactor:
Excellent news. Thanks.

How about support for F2FS external SD? Is it possible and if so, does something else need to be done to a 10.2 rom?
[Galaxy S 4 Mini Android Development] abj2aqua:
Hey [MENTION=3261191]F4k[/MENTION]

I've been using your kernel on my GT-I9192 with a smartassV2 governor on cm11 by sekil, but each time I restart the phone with set on boot applied in Performance Control, the clock speed stays at max frequency unless I change the governor to some other and back again to smartaaV2 after which it works properly. Any solution? thanks.
[Galaxy S 4 Mini Android Development] iFlasher:
Use the perfomance setting of Cyanogenmod instead and reboot. It solves that.
[Galaxy S 4 Mini Android Development] abj2aqua:
Will try for a few hours and get back to you with the results. Thanks a lot. :) :good:
[Galaxy S 4 Mini Android Development] abj2aqua:
Solved the frequency to max problem, but not able to underclock to 162 Mhz now :(
[Galaxy S 4 Mini Android Development] leripe:
Maybe your cpu chip just ain't so good that it can work so low.
[Galaxy S 4 Mini Android Development] Phenom2122:
As far as I have understood it over time, the only cpu app that actually does everything properly is Kernel Tweaker. Other performance control apps will happily display the smartass type settings but never seem to be able to handle them correctly. This has been an issue ever since I first got my android phone and started using these apps and it has never been fixed. And at this point I don't believe it will be.
[Galaxy S 4 Mini Android Development] iFlasher:
Hi F4k! In the latest days I'm do some logs for touchscreen related problems that I say previously. I'm do some logging with dmesg and I found a curiosity thing. Ever when I get touchscreen problems this appears in the dmesg log: (with some variants)

[IMG="Dmesg Log"]http://i57.tinypic.com/2wpj7kg.png[/IMG]

Look at the line that says: "Disable GR Because multi stylus type touch ghosts".

I don't know if this can help, but is interesting because appears when I have the erratic touchscreen problem.

Maybe the problem with touchscreen is in the drivers?

Greetings!

Edit: This is the official generic Atmel MXT driver in his own github

https://github.com/atmel-maxtouch/linux/blob/maxtouch-v3.14/drivers/input/touchscreen/atmel_mxt_ts.c
[Galaxy S 4 Mini Android Development] abj2aqua:
Haha no. Thing is the CM is stopped by the HardLimit set on this kernel, while the PerformanceControl app has support for this. Thats my issue, not my chip.
[Galaxy S 4 Mini Android Development] leripe:
Well all cpu chips are unique from the batch, so while others may get better performance others won't. At least when dealing with low and high frequencies.

Flash via odin ?

Hi everyone,

Can i flash this kernel via odin (ap case) ? because my phone is stuck on boot and i don't have access to recovery mode.

Thanks !
[Galaxy S 4 Mini Android Development] F4k:
You can use Heimdall to flash the boot.img, to flash with Odin boot.img need to be repacked as .tar.md5
[Galaxy S 4 Mini Android Development] bennigecko:
Sorry to hear that since I don't feel comfortable switching to KK yet. There are just to many remaining issues and 10.2 works just perfectly for me.

Anyway, thank you very much for your hard work building that exceptional kernel! I really appreciate it.
[Galaxy S 4 Mini Android Development] bassie1988:
[MENTION=3261191]F4k[/MENTION], This ROM is very nice!! I have been using it for a few weeks now without any problems. Last weekend I went to a festival, and it lasted for 4 days! (Everything off, few text messages and calls, clockspeed Max 810). I really like all the features and customizations. The only question I have for now; Is ART already enough suoported to start using it?

Thanks you for all your work so far!!:D:thumbup:

This a kernel...
[Galaxy S 4 Mini Android Development] Oijkn:
Hi, this problem is fixed or not yet ?

Regards.
[Galaxy S 4 Mini Android Development] F4k:
There's no trouble with wifi, this seems to be a joke...
[Galaxy S 4 Mini Android Development] spanish33:
the fact that users still mention wifi isn't working clearly shows they don't understand that your 1.5 kernel version is meant for roms built after a certain date which has the changes arco made to the wifi module.

I know you mentioned it multiple times already but maybe some persons missed it.
[Galaxy S 4 Mini Android Development] F4k:
I agree that some persons missed it but they missed it because they don't read and don't search before asking, this was answered in multiple occasions.

---------- Post added at 08:14 PM ---------- Previous post was at 08:11 PM ----------

[Galaxy S 4 Mini Android Development] iFlasher:
I think that maybe those updated oficial drivers by atmel have already fixed the problem, because I see a lot of changes on his github.
[Galaxy S 4 Mini Android Development] sysKin:
Can I suggest that you consider "users don't read what I've read" as if it was a programming problem: you find a "code" to solve it :) For example by putting this information on the first page.

As it is now, first sentence of first page says "it works on Android AOSP KitKat ROMs". This is a serious statement and nobody is going to conclude it's untrue from some unclear discussion about how WiFi doesn't work, for unknown reason, for some unspecified ROMs, built before unspecified date, that someone mentioned on page 100...

All I'm saying -- if there's a confusion, then "fixing" its cause might be an alternative to being annoyed by it... I'm a programmer myself and this approach seems to be work quite well for me :D Users seem stupid, but if I think "it was my program that confused them", then I'm no longer powerless in the face of their stupidity.
[Galaxy S 4 Mini Android Development] leripe:
Mmm yeah maybe the first post could say something like this: "This kernel should work on all AOSP kitkat roms, but if issues rise on some rom then the rom is out of date or the kernel just doesn't work with it. The main focus of the kernel is to work with CM11."

:good:
[Galaxy S 4 Mini Android Development] Phenom2122:
Well there is definitely something strange going on with connectivity. Other people have wifi issues, I am unable to tether my internet connection to my pc but otherwise wifi works fine. And it's only with 1.5.0 on every rom I try including the last two releases of Carbon. But I guess the fact that I'm the only one with this problem make me some kind of joker or idiot. Guess I'll just have to stay on 1.4.5 like an idiot.
[Galaxy S 4 Mini Android Development] spanish33:
Maybe not much persons use tethering that is why only you reported it. I tested tethering a couple days ago for a couple minutes and it didn't work for me as well.
[Galaxy S 4 Mini Android Development] Phenom2122:
Thanks dude. I just get really annoyed reading how some people's issues are just brushed aside or ridiculed by a massive peanut gallery. I wasn't even complaining about the issue so much, this is an amazing piece of software that turns our phones into so much more and it's for free.

I dunno, I've been spending a bit of time on another forum where everyone seems to be a know it all dickhead. This forum isn't even ten percent as bad, in fact it's one of the most chilled forums I've been on. I guess I'm just irritated in general. Thank you for confirming the issue dude.
[Galaxy S 4 Mini Android Development] spanish33:
[MENTION=5767881]Phenom2122[/MENTION] no problem, maybe some other users of 1.5 can test tethering for you to confirm the problem.

I really hope here doesn't become like those other forums.

Edit :I will test USB and wifi tethering in detail for you later today and give some additional feedback
[Galaxy S 4 Mini Android Development] FaulFels:
For me teathering is working with this kernel on latest CM11 nightly. I use it a lot in conjunction with my tablet.
[Galaxy S 4 Mini Android Development] F4k:
The fact is that this kernel is in active development, we need a little of common sense, for example version 1.2.5 doesn't mean that will work on latest ROMs, always are changes and user at least should read release notes, if wifi modules get updated in changelog probably it mean in 90% of cases, that ROM was updated too.

And I want to share a couple of words to everybody.

I spend hours and hours and hours testing new features, trying to fix errors while i'm compiling to bring always best experience if possible.

I do this because I like it and I love share my humble project, so I think that users should show a little more of respect for people that spend hours in his life to bring for free, kernels, ROMs, mods, etc. and at least read and search before asking or reporting in many cases stupid bugs that have been answered already in many cases.

I think that nobody should demand or request a fix by posting the same again and again and again, without any log that could help me to fix this suspected issue, simply will become ignored by me if only one person have this issue and no one else has confirmed this.

[MENTION=5767881]Phenom2122[/MENTION] probably you're right and some of the usb patches that I applied in 1.5.0 affected tethering to work as expected.
[Galaxy S 4 Mini Android Development] Phenom2122:
I will look into creating a log file for you. The error in windows is that it is unable to find the IP Address.. I hope that I didn't come across as demanding a fix, this was my second time mentioning this issue here after maybe two weeks? It's not serious as 1.4.5 still works fine.

I was merely frustrated by all the comments I had just read because legitimate bug reports can easily get lost that way.

I'm a little busy at the moment but I will see what I can do about a log a little bit later.
[Galaxy S 4 Mini Android Development] MarkAndroid.UK:
Am using WiFi tethering to post this. I am currently testing SlimKat weekly v6 with no problems so far after flashing 1.5 over it.
[Galaxy S 4 Mini Android Development] F4k:
It's using USB tethering, the issue exist and is caused by this commit, so it will be reverted on next build.
[Galaxy S 4 Mini Android Development] spanish33:
yes confirmed only USB tethering affected. wifi and bluetooth tethering working as expected on version 1.5.0.

We appreciate all your hard work done for the s4mini so don't think for a moment we don't.
[Galaxy S 4 Mini Android Development] xbrunox:
i'm on last cyanogen nightly, wifi thetering with 1.5 kernel works well.
[Galaxy S 4 Mini Android Development] iFlasher:
F4k in order to help you... Are you using the battery patches by Venkat Devarasetty or something related to msm-spm? I say this because I think that tweaks be the cause of the random reboots that not only happens to me... I tried the kernel in other duos model and happens too. I don't know if the problem only happens to this model or is general. Also in the last-kmsg log I get a lot of "Unable to handle kernel paging request at virtual address" after a random reboot, you can see this on the logs that I send you before.

Also the problem not happens ever, if you do a normal use to your phone this won't happens usually, is more often to happens if you play games or browse with a lot of tabs after a while.

I know that say this to you a lot of times (about the random reboots) can be annoying, but I only try to help you to improve your kernel even if the help is little and not sufficient.

Greetings.
[Galaxy S 4 Mini Android Development] sysKin:
Hi F4k, let me assure you that I love and appreciate your work and I did not mean for my post to look like I'm complaining/criticising in any way or form. Apologies it it sounded like it.

It's just that you appeared to be annoyed on last page, and it reminded me how it used to be annoyed by users "not reading" too, long time ago (when I was doing XviD video codec development on Doom9 forums, man it was like ten years ago!).

But at one point I forced myself into a slightly different mindset, in which every problem that affects me is my problem. See, you wrote, in red, "There's no trouble with wifi" while obviously *you* have some problem with users having problem with wifi. So, from a certain point of view there is *some* problem with wifi, it's just not in code. Maybe it's not even fixable, but it's there :D

Ever since I'm thinking in those terms, it's less annoying for me, and the software I write produces less feedback I have to read. Which is why I wanted to share this.

Thanks for reading ~ and sorry for off-topic.

Thank you for your work.

I have a question about support for F2FS on external SD on pre 4.4 roms. Is it possible and if so, does something else need to be done to a 10.2 rom?
[Galaxy S 4 Mini Android Development] F4k:
I'm not sure that you can, ROM needs to be compiled with this support.
[Galaxy S 4 Mini Android Development] phz.:
Hello. I am still very happy with the Kernel. But I just came up with one feature that does not work for me.

When I underclock the cpu to 162 Mhz I am able to save some power as long as I reboot the phone.

After a reboot the minimum value jumps back to 384 Mhz. Is there a way to fix it? Thank you.
[Galaxy S 4 Mini Android Development] TNCS:
What app are you using for underclock? In the app, did you make sure you have chose 'Set on boot' on similar? This isn't a kernel problem but rather the app that you use.
[Galaxy S 4 Mini Android Development] GNUDroid:
Please people reduce the amount of noop questions. If you would have read here the forum, you should know that there are some apps which are common to adjust the kernel frequencies, build in performance control, performance control app (download from an old post from f4k, kernel tweaker app (play store), and some more....!

I use kernel tweaker, and everything(!!!) is working fine for me with f4k kernel and kernel tweaker.

People please read, do not spam this thread with always the old stuff. I don't want to see f4k annoyed. He does the best kernel ever for us.
[Galaxy S 4 Mini Android Development] phz.:
Thanks for replying. I am using F4ktion Kernel alongside the CarbonROM from the same author. I tried to permanently set 162 Mhz clockspeed both with "Set on boot" checked and unchecked but the setting disappeared after rebooting. The same problem has just been reported in the CarbonROM thread with an official reply by F4k http://xdaforums.com/showpost.php?p=53918659&postcount=1333

So let's just wait :)

edit: [MENTION=4643283]GNUDroid[/MENTION]: You are right and thank you for summing this up. I just was confused that the integrated settings weren't working. Sorry for the fuss.
[Galaxy S 4 Mini Android Development] DerMoeJoe:
can someone confirm that bluetooth doen't works?

iÄve installed f4k 1.50 in my i9195 with cm11 m7 but i can't activate BT.

Just a quick question.. What do you recommend if my phone runs super hot while charging on the charger? What to change and how? Thanx
[Galaxy S 4 Mini Android Development] iFlasher:
Simple... Don't use it while it's charging.

There is not setting to get it cold while you are doing various task with the phone in the charger.

If you get it hot it's because the phone is getting more energy and the phone is doing something that requires a lot of CPU .

So, you can deal with it and use less the phone when its in the charger or simply don't use it while its charging.

PD: Well, you can try under voltage and under clock or close all apps in background an use the phone with less intensive apps... It maybe help you a little but not expect a lot of improvement.

Greetings ;)
