[POLL] Kernel Knowledge - Verizon Samsung Galaxy S III

I am experienced with rooting and flashing Roms, but I have never flashed a Kernel. I know how to and I know why I would need/want to. I am just wondering what I need to do if I decide to flash a different Rom or even return to stock Rom. Example: If I flash a Kernel while running The Executioner 3 Rom for my rooted Verizon Samsung Galaxy S III, would I need to restore that Rom's original Kernel before flashing a different custom or stock Rom?

Re: [Q] Kernel Knowledge
Depends on the kernel.
Check kernel thread.
But I doubt you will have any problems

So pretty much I would just be able to wipe data and cache and flash new rom as usual?

Nah when you flash a new rom, it flashes its own packaged kernel as well. If you flash a newer version of that rom, say Executioner 3.5 was released, it would also flash its own kernel so you would need to reflash your other custom kernel if you wanted that back. If you're moving between different roms, you wipe and clear away all of the previous mods/kernels/etc that you flashed from your prior rom.

Questions and help go in Q&A
I changed the title to reflect a POLL rather than question
FNM

what i do is set up rom to my liking, make a nandroid, then flash kernel, if i dont like the kernel i go back back to my nandroid.

Thank you all for the great answers.

[Q] A question regarding flashing ROM

Hi all. I'm sorry if this has maybe asked before, but i've read several guides and topics and didn't quite get it. What is the difference between flashing a rom via Clockwork mod and odin? Currently I have Lite'ning Rom v6. 1 XXKH3, KERNEL version [email protected] #20 and I was wondering what are the right steps to change to another custom rom(I have a galaxy s 2 and i was planning to try a ics rom). Thanks in advance
from what i have gathered through flashing roms on my sgs2 odin if for official samsung roms and CWM if for home made roms but i may be wrong
Thank you for your reply. So if i want to go back to stock firmware I shall use odin and clockwork for custom roms? Anyone else can confrim this?

Just for future reference, there is a search function on these forums. For example, I typed 'custom kernel stock rom' into it and a whole bunch of useful information appeared.
Having said that...
Is your phone s-off/rooted? You could flash a custom kernel provided that the build numbers are compatible. For example, Bricked kernel is stated to work with the majority of roms since it creates a boot.img from the one on the phone. Ultimately I would recommend extreme care and I would personally be flashing a stock-look custom rom if you still wanted the stock experience with the custom kernel.

[Q] GT-5113 Stock Firmware

Hi,
I want to know if there is any way to restore my tab to stock firmware? I can't find any links for GT-5113 ROM.
The reason to store the stock ROM is that I have installed CM9 on my tab and now I am unable to install Infected / Cleanrom. It hangs on Samsung boot screen after installing these roms via CWM.
Thanks.

As you realized AFTER the fact, creating a thread in development means you have something to offer to others,
not asking questions. FYI: I stopped using CM9 ROMs a long time ago because they frequently contain MANY
hidden bugs, only work properly when loaded with certain kernels, certain CWMs ... bottom line is you're
just one of the latest victims. Try a factory reset. Then ODIN the CWM in my Root thread. Then install
the ORIGINAL v1.0 CleanRom. It's the best of current custom ROMs and NO, we still don't have a stock GT-P5113.

We had the same situation, so hope this help.
I used odin to flash the gt-5110 stock Rom followed the guide in restore stock rom in galaxy tab 2 general section .After flashed my model gt-5113 became gt5110...lolz then i flashed the Clean Rom v1.1 then my model was back to Gt-5113..now I decide to stay at stock rom because Cm9 sucks...waiting for Aokp official.
If have any question pm me, I'll think i can help your tab 2 back to stock. [email protected]

Thanks, will try both the suggestions one by one.
The only problem with ODIN at the moment is that you can't reset the flash counter, I already have it at 3
Solved
Hi Glenn,
I was able to install CleanRom, by installing the CWM posted in your thread.
Thanks.

When you flashed the 5110 rom, did you have a problem with the language (Mine is currently in a foreign language)?
if so, when you flashed the Clean Rom did your tablet revert to the proper language?
Thanks
You can restore to stock using my guide. (link in signature) It should now be in English.

[Q] shw m110s

good day to all..
im new with this phone..this one is a korean version of galaxy s1(shw m110s)
im confused with how to install custom roms here...
what do i need to download..a kernel or a custom rom?
thanks xda
Moved to General Q&A.
The kernel allows the ROM to communicate with the hardware specific to your device. All ROMs have a kernel build-in. If the custom ROM is designed fir your phone, it will work fine. If the ROM was intended for a device in the same family as yours, you can flash that ROM, then flash the kernel for your phone, & it'll work. If the ROM was designed for a completely different device, nothing will get it to work.
Remember to always do a nandroid backup before flashing stuff!!

[Q] Question about overclocking~ (Note 2 N7100)

Hey xda~ :laugh: noobynoob here and I got a few questions about overclocking, here we go:
1. Is it safe?
Just bought a Note 2 N7100 and got it in a bootloop [scared me senseless, thank god i fixed it]
2. Kernels?
Um what are kernels and what do they differ?
3.Are all kernels for overclocking compatible for my device/rom?:fingers-crossed:
Note 2 N7100 with Dr.Ketan's Custom Rom v10.0 android version 4.4.2 (I currently have my eyes on this kernel: http://forum.xda-developers.com/showthread.php?t=2001838)
4.What kernel do you guys recommend (in case this one isnt compatible or if you just know a better one):victory:
I'm open to suggestions, I just want whats best for my phone
5.If something goes wrong flashing the kernel is there a chance I get bricked/stuck in a bootloop?
already messed up once when trying to flash my custom rom, im afraid itll happen again
ThanQ :laugh:

The kernel, in the simplest terms, is the piece of software in the operating system that tells the OS how to use the hardware.
Custom kernels typically take the stock kernel and modify the settings, and/or add features and setting parameters (often ported from other custom kernels).
3.Are all kernels for overclocking compatible for my device/rom?:fingers-crossed:

I don't know. It's your responsibility to make sure it's compatible. I know Samsung makes many different versions of their Notes and Galaxy XS models (for different carriers, different regions of the world, etc), so a kernel for one version of the Note 2 might not work with your Note 2.
Further, just like it is with computer processors, not all are created equal. After manufacturing, processors are tested sorted into "bins" (literally) according to how well they work. Typically processors are all underclocked below their potential to some degree. That way they're not maxed out and overheating won't be a problem. Since they're underclocked, that means they can be overclocked to their true potential, but how far is a roll of the dice. One guy's Note 2 might have a processor from a higher bin and stably overclockable to 1.9GHz. Or you might have gotten one from a lower bin, and all you can OC it to is 1.7GHz. OC'ing too far will cause glitches and crashes.

I can't help you with that. It's best that you just read up on the kernel(s) you want to try, and by "read", I mean start from the first post, and read every post until you've read them all. That way you know about possible problems and how to sort them out if you encounter them.
5.If something goes wrong flashing the kernel is there a chance I get bricked/stuck in a bootloop?

If you have a custom ROM, that means you have a custom recovery (TWRP, CWM, etc). From within the recovery you can do what's called a nandroid backup. It probably won't be labeled as "nandroid" (even though that's what we call it), but just a backup. This creates an "image" of your phone as it is when you run the backup. Store it on your SD card or PC (or both). If something goes wrong, you should still be able to reboot into recovery and restore your backup. Or, if you have a copy of your current kernel (custom ROMs sometimes have their own kernels, and might be available to download), you can just reflash the old kernel in recovery.

hmmm I guess ill need to read up more, I read on the kernels page something about needing a touchwiz based rom? what does that mean and how do I tell if my rom is tocuh based? As for that backup idea, that seems pretty useful, im gonna do that right now

TouchWiz is what Samsung calls its interfaces.
