Somebody please explain custom kernels! - Verizon Samsung Galaxy S 4

I have a Verizon nc5 with Hyperdrive 19, just wondering what the deal is with different kernels? Can I install the ktoonsez kernel or will it brick my phone? I've soft bricked once and don't want to do it again!

Only people on MDK can run custom kernels. And custom kernels let you use more features for the rom, like an aosp rom. Safestrap users cant use aosp because our kernel is different from aosp and so wifi is usually messed up and USB transfers are broken.

So when I flashed hyperdrive, I selected the stockish kernel, not the safestrap one. It works fine, also flashed the nc5 modules to fix Wi-Fi, but those are the only two I can use, correct?

[Q] Flashing New Roms

so, this may be answered somewhere else. but i couldnt really find a straight answer. i have bionix fusion flashed right now, so if i want to flash another rom, can i just flash it with bionix still installed? or should i reflash to stock then flash a new rom? sorry if this was confusing, just trying to get straight answer.
You can do either, most customs roms do a wipe for you automatically so it's like a fresh install. Just remember to disable any lag fix you have running

No. you must start from fresh (stock). Odin back to JFD then root then install the rom. If you have voodoo installed, always disable it before you flash anything.

I have flashed many times over custom roms, you don't need to go to stock unless you are going from a 2.2 to a 2.1 rom

but to avoid future errors it's always a good habit to start from stock, especially if you're from bionix for instance and would like to install froyo. That huge modification requires a start from stock in order to avoid future errors. if it's minimal flashing then you can just flash without going to stock.

I would agree with that

That's not true. You can do a straight flash over another rom. However, after you flash 4 or 5 roms over and over, it is good on occasion to flash to stock rom. I must have flashed every single Sombionix and Eugene rom available and only flashed to stock before flashing one of their roms once or twice.
Honestly if you flash to stock rom everytime, then flash a custom rom, you're really doing extra work for nothing as a few posts up had stated " most custom roms wipe everything anyways"; so just flashing back to stock, then flashing a custom rom is kinda pointless.
Moved to Q&A as not development.
Answered my question
I was just about to ask the same question. Thanks to all for this thread.

[Q] Updating to a Jelly Bean Custom Rom

Hi there!
I am wanting to update my Samsung Galaxy GT-i9300 but am worried about the process because of having installed a custom kernel previously (would this muck up installing a new custom rom I wonder..)
Please find attached a screenshot of the settings and please tell me what I should do (if anything needs done) before I flash a new custom rom.
Cheers!
if you're worried about kernels, then just flash stock kernel then flash a custom rom on it.

kk, could you provide me with a suitable stock kernel (or links to one) which will be compatible with the rom I have installed?
any stock kernel that is for jb will be fine.

I am on android version 4.0.4 (so technically not JellyBean). and its safe to flash a stock kernel for JB despite being on that version before I flash a custom rom?
Sorry for asking, get confused easily..
you should be fine updating with a custom kernel (as all roms flash a kernel as well). Just make sure you factory reset when moving from ics to JB as you will most likely encounter problems if you don't.

I would suggest flashing ICS stock kernel first if you're worried. I thought you were already on jb.

Easy
Reflash the stock ics ROM
And flash any custom ROM you want
Enjoy

not sure cuz i didnt pack a kernel with it. if you want to try this install some mdk modules after the rom http://omniimpact.com/android/roms/myfishbear/GS4/jfltevzw-MDK-modules.zip
Can you pack a kernel with it for us on MDK? If there was a compatible kernel it could just be flashed after installing the rom but I don't think there is a MI1 kernel?
I don't see how wifi will work without someone making a compatible kernel?

try flashing the rom, mdk modules, and root. it should work. if not try chronic kernel 4.2. i believe the stock kernel will kill loki without modifications. i may be wrong.
you can find the kernel here http://forum.xda-developers.com/showthread.php?t=2319243
It won't activate the phone in the set up wizard.
I guess with this it doesn't read the sim card it says there is a problem with it and won't activate.

4.3 Mj7 and rooted,what can i do?

i just replaced my phone with warranty then promptly updated it to 4.3 and rooted it using vroot. i wanted to install a recovery and eventually install a rom with a main focus on gaming if there is such a rom..., however i keep trying different recoveries and they all keep failing to install as far as i can see.. im guessing there isnt one for 4.3?
You're on MJ7, you can't install a custom recovery or ROM. This has been discussed a million bagillion times already.

[Q] ROM for Verizon SCH-1545 MK2

Succesfully restored using Heimdall on Mac OS, then restored again using Kies after an erred attempt at wipe using Safestrap.
Now safe - looking for a way to load an un-bloated ROM for Verizon SCH-I545 MK2 using Safestrap. Preferrably from Cyanogen, any recommendations? Experience?

Your ONLY option right now are TW ROMs with a MJ7/MK2 base.

Questions like this belong in the Q and A thread, however, best rom threads also get closed as XDA is not a support site and members are expected to do their own research into what suits them best.
Read, study, try them all, only you can make the determination.
