[Q] Android Kernal, what is it? - Galaxy Note 3 Q&A, Help & Troubleshooting

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?)

[Q] putting a custom ROM/kernel on i9505g GE MFD

I have a brand new GE Android 4.2.2 running MFD that I'd like to be able to flash Android 4.3 and/or the Faux Kernel on to enhance functionality. I've been scouring the xda forums for a couple of days and can't find any posts with anyone attempting this. I had no problem rooting the phone and installing CWM recovery but for the life of me I can't get a custom rom or kernel on it. I have tried i9505 MF8 roms and various kernels including Faux. I've tried dirty flashing and clean flashing. I can't the phone to boot after installing any of these and always have to revert back to my stock backup. (I believe it because I'm on MFD).
Anyone else trying this, something similar, or have any ideas?
Any advice would be greatly Appreciated.

It doesn't work yet. We have no custom ROMs or custom recovery for our phone (9505G) as of yet. The 4.3 leak has a lot of issues for most of us.

4.3 on GE
Thanks malybru!
I was able to flash 4.3 on my i9505 GE this evening.
It's a little buggy. Navigation is gone and the GPS doesn't seem to function correctly.
The rom does say experimental so I was expecting some degree of bugs.
Frankly I'm just happy I was finally able to flash something on my phone.
Are there any other roms available for the i9505 GE?
I haven't been able to find any, but of course I was unable to find the 4.3.
Thanks again for your help
No Roms

The only thing I wasn't able to load were the MF8 roms such as Omega. I was never in a soft brick state. It's disappointing to know there are no roms out yet but not surprising. I was wondering how the community would support the GE phones. I wasn't sure if there'd be hoards of developers using the phones or none at all.
XDA should have a GE category in the i9505 section.
Thanks for the advice.

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).

10X
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?

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

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.

well on first note you can flash a rooted kk and keep recovery there are two ways of doing so, now for your first question recommending roms is not that good because everyone has a different preference in my case I need power and battery life since I mainly use my phone for gaming but you might have something else in mind so it's always best to just just flash on your own until you find something that suits your needs
Madhi rom is a pretty good rom and stable rom. So far I found 0 bugs with my everyday use. I recommend it. And having a nandroid backup makes the return to your stock rom a 5 minute process, if you didn't like it

Thanks man, can you give me a link? And nandroid backup is in cwm recovery right?
nandroid backup is called the process of taking backup your entire phone . data system cache etc.
You can find it in all custom recovery programs cwm , twrp .VERY VERY VERY usefull
I used both cwm and twrp for nandroid backup and it's a pretty straightforward process.

I have an SGH-i337z on Cricket and I was able to root and install TWRP using hroark13's method (http://forum.xda-developers.com/gal...cket-aio-sgh-i337z-jflteaio-twrp-2-7-t2858698)
I've been trying various CM builds, the Google Play Edition ROM and PACMAN, but they all seem to have issues (5GHz WiFi, one app or another not working properly, notification glitches). To be fair, they are AT&T ROMs. Also, it takes a bit of work to install as you have to remove the asserts line from each ROM before installing. But if you just want to root and use TWRP to backup it works fine!

Just out of curiosity, was the GPE ROM you tried the Lollipop one? Also, are there any roms for this phone that work well and stable in your experience?
I haven't tried any lollipop roms yet. The 4.4.4 kitkat GPE ROM was stable with the exception of breaking a music streaming app I use (subsonic). It was also the only ROM that identified the carrier as Cricket instead of AT&T.
Pacman I didn't really like so i can't speak much for its stability.
CM11 can be hit or miss. The nightly seem more stable than the stable or milestone versions usually, but one gave me 5GHz wifi problems. I was never able to use 5GHz with the milestone I tried.
Right now i am using 12/13 nightly CM11 and it has been running very well. I really like the slider shortcuts on the CM lock screen, so I'll probably just stick with CM.

Yes, CM11 is working great! If anything is broken I haven't come across it yet. There are certainly a lot available and any unified or AT&T ROM should work (no need for safestrap), so feel free to try out anything that looks good! I liked GPE and it seemed to work really well until I found it didn't work with one app I use occasionally (subsonic). You might not have any issues with apps you use. I also seemed to get better battery life with GPE. The wifi issue I had with an older CM11 build seems to have been fixed, so that's working well now. The author of the root I used seems to like Skyfall, so you could go that way if you like touchwiz.
Have some fun trying out a couple, and make a backup before installing something different so you can easily go back if you decide you liked one better.

FWIW, I've gotten Goldeneye, Skyfall and stock T-mobile running on my i337z with TWRP. I figured out that I needed to flash my phone's modules after flashing a touchwiz ROM for it to boot and run correctly. My i337z is on ND3. I uploaded the ND3 and NE2 modules in this post: http://forum.xda-developers.com/showpost.php?p=57407130&postcount=75.

[Q] Phone refuses to boot with a rom

Hi, I've been trying to install a custom rom (at this point ANY custom rom) on my friend's phone. I have worked on several phones before, including my own sprint GS3, but this is my first time trying to work around a locked bootloader, and BOY is it a pain, haha. I'm no dev, but I would like to think that I'm pretty competent.
First a few things to note, are that the phone is currently on NI1 (Been too much of a sissy to go to NJ4 in case it screws something up, I don't even know why), it is the 16Gb version, I am using an external sd card to flash everything, and yes I am flashing loki-doki after everything.
So what I've done so far is:
- Try to install TWRP
- Find out that won't work and finally figure out I need safestrap
- Successfully install safestrap after using towelroot by ODIN-ing the NC1 kernel then going back to the NI1 kernel
- Try to flash Resurrection Remix and KToonsez kernel using a new rom-slot, and wind up soft-bricking (stuck on bootloader screen, can get to download mode)
- ODIN NB1 tar then ODIN NI1 update
- Repeat the last few steps several times because I'm too idiotic to realize that it JUST ISN'T GOING TO WORK!
- Finally find a reference to flashing the ATT kernel modules after the rom. That got me past the soft brick and safestrap screen, but I don't even see a boot animation
As of right now my sequence to successfully not soft-bricking (what an accomplishment) is to flash the rom>gapps>ATT kernel module>supersu>loki-doki>wipe dalvik/cache
Now, is it worth it having already spend a good 7 hours, just to get a custom rom? Of course not, it's not my phone and my friend isn't picky. He'd be just fine with rooted TW. However, It kills me that I don't know what's going on, so here I am lol.
TL;DR: Phone has safestrap, is rooted, but any time I flash a rom it gets past the boot loader/safestrap screen and never shows a boot animation, or anything past that. Can anyone help figure out what's going on please?
Thanks in advance.
You can only flash touch wiz based roms with safestrap and you can't flash kernels with safestrap. That's been your problem with soft bricking.

Thanks guys. I thought I read through the whole thread, but there is so much information, it's pretty scattered, I must have missed the thing about only TW roms working.
Now a few more questions:
1) Is it worth updating to NJ4? The phone is new and doesn't have any app data or anything that would be missed by updating. I see quite a few roms in 4.4.4, but it looks like most of them are AOSP based, which leads me to my next question...
2) Is there a way to get AOSP roms to work? I see all of these AOSP based roms, obviously for this phone, but it would be pointless to make them if they don't work.

It wouldn't hurt to update to nj4. But it's not going to help you either. Only phones on mdb or mdl bootloader can flash non touch wiz based roms using loki. And you can't go back to those bootloaders

Oh, I get it now. That didn't quite register before. So just to confirm, after I flash the rom (which already has its own custom kernel included), I still need to flash the stock ATT kernel, correct?
Flash the rom, super su, and the att module for your base. Hyperdrive is a very good rom, good luck. Also the rom doesn't include a kernel, your original kernel stays put. That's why only tw roms work, because your new rom has to be compatible with the kernel already on your phone.
Just reporting in, I now have the phone up and running using Hyperdrive Rom. Thanks for the help!
I actually had a problem where it would not shut down correctly, but found out it was because I was installing the rom in a rom-slot in safestrap. As soon as I tried the stock rom slot, it worked flawlessly.
