[Q] Android Kernal, what is it?

I'm using a Galaxy Note 3. I've flashed it with a ROM called X-Note which was really great! And it had 3 options for custom kernals to use. I can't remember which one I chose, all I remember is the other two seemed to prevent my phone from booting. (maybe the issue, I'm no expert).
And now I have recently flashed CM11 via temasek's build and it's working very well indeed. The thing is though, they seem to have their own kernal that I can use. I'm not though, I'm just wondering what it is and if I should try using it.
From my experience some kernals can stop the phone from booting. Is this true? Maybe it was just coincidence for me? Can anyone explain?

(as a side question, X-Note also came with a custom version of TWRP. I'm thinking of going back to Clockworkmod recovery as there's a few new ones on the GN3 XDA threads. What would be the easiest and cleanest way to do this?)

WiFi with ktoonz kernel

Hey guys.
I flashed the ktoonz kernel about a week ago and it works just fine except one thing: after a reboot my phone has forgotten my wifi password and i have to connect it again.
every time i restart the phone it's the same. it worked on stock kernel.
does anyone know this problem? it's quite annoying..
--edit--
i forgot to mention that i'm on stock samsung rom android 4.3 with touchwiz
and it's the international s4 (i9505).

Question; after installed I try to flash a custom kernel (AOSP/TW/GE - 4.2/4.3 KT-SGS4 - MFD - KTweaker) and everything started to work wrong (no wifi,net fc,and many others)please tel my what kernel it's perfect for your rom and also if it's realy ned to flash a custom kernel ?

A custom kernel is not required for these ROMs as they include the stock Samsung TouchWiz kernel which I'd say is probably the best kernel for the stock ROMs.

Isn't there a way to get WiFi working without flashing a new rom? I don't want to wipe the phone actually and the kernel is pretty nice I think.
It's pretty konservative with the battery and gives me extra power when I need it.
Isn't there a WiFi-fix or something like that?

WiFi-fix

Got the same issue with 4.4.2 and newest kernel version...
Tried changing build.prop line but with no success.
Is there any kind of help or a adequate wifi fix for kitkat?
Solved: wiped cache and dalvik and fixed permissions couple of times. Now it works
Sent from my GT-I9505 using xda app-developers app

I'm using GT-I9505 "international" with Paranoid Android 4.45 and successfully installed Ktoonsez kernel (3.4.94) with flashify app using Philztouch cwm recovery.
No problems at all, everything works, not tweaking by KTweaker, just raised 2.2GHz from PA's processor settings, ondemand as processor governor and Noop on i/o scheduler.
Tried few KTweaker profiles first but didn't find any good what understands to drop processor on deep sleep mode, almost all keeps it running all the time, PA's own handling with freshly installed KT-SGS4 kernel did best job for me.
Testing with profiles was frustrating thing, there wasn't way back to same situation what I got on fresh install.. few PA flashes later stand on "default".
Props to KToonsez (kernel), Christian Göllner (Flashify) and Paranoid Android.

[Q] freezes on 4.4.2 custom roms / kernels

on the latest d802 4.4.2 custom roms and kernels i get a lot of freezes.
it will freeze in the middle of an animation and will take some seconds up to some minutes and then working normal again.
sometimes i have to hard-reboot to get out of freeze / lag.
on older 4.4.2 slimroms i never had this behavior, only since some weeks with new roms / kernels.
i`ve tried every rom / kernel combo but sooner or later i will get a freeze again.
could a revert to stock and re-rooting / flashing custom rom maybe a solution? i`m afraid to do this because of the long time to backup my 32gb data.
what are your experiences with the latest 4.4.2 roms and kernels? did you find a solution for this with any combo or fixes?
help would be appreciated.

The only thing I can say is I own the VS980 version of the device and i've tried every single 4.4 rom offered on this sight and have the same issue with all. Most of the time i'm using the device and it freezes, sometimes reboots, and sometimes comes out of it after a few minutes. Also not being able to wake the device only seeing a black screen and forced to hard reboot device. 4.3 seems to be a much better with these issues but not completely solved for me. I'm hoping the release of 4.4 source from lg will fix these issues but i'm unsure. So at least your not alone in these problems lol. I've tried multiple kernels and governors etc. Bumping up the min freq on the cpu seems to help and changing to interactive governor but doesn't eliminate the issue just help. I thought my next move would be to use lg flash tool and update to latest firmware reroot and install cwm.

i think i will do the same today after work. hopefully this helps.
the better option would be to stay some days on stock rom to ensure there is no hardware defect. but i can`t stand stock so this would be a hard route! ^_^

Yea unfortunately it seems very common among these devices so i'm pretty confident it's a software issue although i'm not 100% sure of that. I ran a flex rom for a few days on 4.2.2 and didn't have any of the same issues.

added a poll as a matter of interest.

omni-ROM, Mokee rom, vanir rom etc.freezing problem still continues.

Using CM11 (4.4.2) for 5 days with zero freezes so far.. note that this is on D800, not 802.

Yes, stock cm kernel.
I'm thinking back now and it did freeze once when first signing into the Google account immediately after flashing the ROM, but nothing after that. So.. nearly spotless

Nice! Maybe they are getting the issues ironed out. Haven't been on cm11 for a week or so since it was the worst with freezes for me. I'll have to give it another shot.

Best of luck! To be specific, I'm using the snapshot release of cm11... still don't trust the nightly releases

i did a lg flash tool stock restore, factory reset and OTA updates. now the freezes did not come back until now *knock on wood*.
when i did a backup of the sd there was one corrupt media file which was not able to transfer.
maybe the media scanner did go crazy and was the reason for the freezes.

using cm11 m3 on my d802... very little freezes compared to previous nightlies, fingers crossed

My galaxy s4 has lags?

Hi all, I'm experieng a very bad and fastidious problem. I was on danvdh GE rom with my galaxy gt-i9505 and all was working properly. A day I have the (bad) idea to update the kernel. I was using kt kernel. I updated it and I don't liked because it was a little bit laggy, so i reverted back to a previous version. No way, the lag was still there. I full wiped intalling faux123 kernel but lag was still there. I did many and many full wipes and I tryed many and many roms and kernels. I don't think that my problem is a rom or a kernel. I tryed as well tw roms (unusable with this problems because they are slow and with this problem much more) and GE roms. I also notice a lag in the bootanimation, samsung or ge edition, after a full wipe. What's wrong with my phone? I'm with the old bootloader but I don't think this is the problem because before all was working properly! Do you think that my phone is damaged or what? I tryed as well a Deep Clean 1 but nothing, still laggy! Saying my phone is laggy I mean that:
1) the bootanimation is laggy
2) using the phone I can see animations lags and no smoothness but not ever.. every 1 minute? Don't know what's happening!
Please help me, I'm going crazy! I hate lags... thanks in advantage..

N9005xxuenb4 hot restarts

When i see that phone restart from an app, like gplay, maps, etc, and it does this every day, i know that it's rom fault. This new phone have this problem. Brand new.
Other note i own, on 4.3 its super stable.
What rom could i put on this note with 4.4.2 to be super stable?
An rom with good battery and quite stable.
Thanks.

I take the risk and update with mobile odin on xxuend3. Seems ok for now. Root, xposed remain, knox 0x0. Old bootloader remain, as well the modem.
If anyone know an better rom then xxuend3 pls post it. Don't want any newer then this, because i need root.

You could update it to the latest NG iterations. But tbh the battery is even worse there.
You can flash custom ROMs that fit your liking in the Android Development forums. I used Xnote and I didn't have random reboots because of the ROM, but because of the kernel.
Compulsion Kernel or ColonelX kernels are what cool kids use nowadays, mainly because of stability.
If I were to ever go back to TW ROMs however, I'd use the S5 ports.
