[Q] Do custom roms have kernels? Like CM12 - Android Q&A, Help & Troubleshooting

I have never installed a custom rom in my 4 year android experience. But alwaya modified stock roms. Now I have gotten tired of the stock lollipop performance on my note 3 n900. A nexus 5 is way faster than my note 3.
I am thinking about flashing CM12.1 on my note 3.
But I am scared about kernel stuff.
Do custom roms replace the stock kernel? Like CM12.1
And is it dangerous to install custom kernels.
Also
How easy it is to go to stock after custom rom?
Is it just a simple flash through odin?
I read somewhere that odin mode can also get corrupted.
I want to know
How easy it is to mess up the odin mode and Brick my device 100 percent
As far as my knowledge goes
As long as there is odin
U can flash stock rom.
Plssssss do give answers any one who is advanced in android at such a level.
It wud mean a looooot to me.

help with my new s2

i am from galaxy mini forum so get a galaxy s2 but how to know if it is S2 or S2 GT-i9100 o and what the diffirence?? and can you gays pleas link me to a tut aboug instaling costome recovery, which ODIN to use and so on .... last thing which is the best stable rom to use .....thanks in advance
1) Check the sticker on the phone chassis under the battery.
2) Differences between SGS2 variants ? Wikipedia.
3) Just about everything you need to know to get you started is in the Stickies.
4) There's no such thing as the "best stable rom to use". There are a heap of custom roms for the SGS2, it's an individual preference thing. And because no two people use their phone the same way or have it setup the same, and because component-wise no two phones come out of the factory exactly the same, your experience with a particular rom will most likely vary from mine.
The best thing to do is to get your phone rooted, preferably with CWM installed. This will enable you to backup, restore & flash roms/kernels in a matter of minutes. You can than try a bunch of roms for yourself. If you find you don't like a rom you try, it's easy to go back to your previous setup easily by restoring a backup; recommended regularly/before you flash anything to your phone.
ok so by flashing cwm and then a costom rom the divise will root by it self and do i have to flash a stock ics rom to install a costom ics rom??????
Lackchoo,
Flash one of Chainfire's kernels. His instructions are very clear. That will give you root and CWM, and possibly also a yellow triangle at startup which you shouldn't worry about at all.
You don't need to flash a stock ICS ROM to flash a custom ROM. After rooted, in CWM, just install the downloaded ZIP ROM file of the custom ROM. You will keep root and triangle will go away.
Ditto what the above person said about ROM's. However, you can try Cyanogen (Do a 'stable' release, not a 'nightly'), its the most 'popular' ROM in terms of numbers. One can't and shouldn't say which one is best. But for a newbie, I think Cyanogen is a good place to start. Perhaps it will give you the least issues and the most 'oohs!' for your initial newbie effort
I don't have the links with me from the smart phone, but just search 'chainfire kernel root galaxy s2' and 'cyanogen galaxy s2' and you should find the relevant thread. Read it slowly and repeatedly! I know I had to

Now that I have Stock JB.....

So far my experience with the recent update has been mediocre, Its been 2 days now for me and i'm ready to re-root my device and start tackling some of the bloatware to help improve performance or maybe installing some custom roms again(No Really this phone had better fluidity when i was running GB)....My questions is: now that i'm running stock 4.1 is the rooting process any different from when I was running stock 4.0.4?
I can't post links but on Galaxy note hacks there is a rooting guide specific to my phone...but not specific to the software version.
Thank You

That link is rather useless without explaining how to get recovery...
Op yes.
rooting jb is the same... use Odin to flash a custom recovery image.
Then use that recovery to flash zips, for root, or a completely different Rom.

[Q] complete noob but need answers xD

ok so i bought my international version galaxy s3 from ebay. it was already rooted and modified. i know cause i
cant receive updates. unless i use triangle away. obviously i still dont get updates because im on a custom rom which i have no idea what custom rom it is. rom manager doesnt tell me. rom manager says
that my custom rom isnt setup to recieve updates.
im on 4.1.2 JB. what im wanting to know is. can i flash straight to cyanogenmod 10.2 from my custom rom?
and will flashing to 10.2 keep me on 4.1.2 JB but with the cyan tweaks/mods or will it be 4.3?
also what is the best method to save my imei from any dramas. i also dont want to lose my network which ive seen people have this problem also.
is there anyway for me to find out what custom rom im using? i know that i have clockworkmod 6 installed.
im using 19300XXELLA on what i beleive is a custom kernel smp but cant be sure.
im sure this post has not made much sense but hope you can undersyand what km asking
i also looked at the sticky threads. they gave answers but i felt they werent the answers i needed specifically for me. except the imei question
First you can know your custom ROM most probably from about device info...
Second you can flash cm 10.2 or cm11 without any hassles with imei but if you want any Samsung based custom rom you should flash a newer modem... Search for them there are flashable zips available...
Before doing this,backup your efs by one of many apps on play store like ktool or samsung tool..
Cm10.2 means it is 4.3 android and cm11 will be 4.4.2..
And don't expect features of samsung firmware in those roms.. I mean better camera, swipe for screen shot and other features.. They are exclusive for samsung based roms...
For cm11 you must update your recovery to latest search for it flash then via Odin
Or cwm flashable zips are also available...

No name android phones and CM

Hey guys,
Got on hands noname Chinese android phone with lollipop on board (even though it says 6.0.1 in settings) and MTK6580 quad processor, 3.10.72 kernel
can I somehow put cyanogen rom from another phone?
Yes, find another phone using that chip: https://en.wikipedia.org/wiki/List_of_devices_using_Mediatek_SoCs
Then go here: http://www.needrom.com and find THAT phone(s) and see if there is a custom rom for THAT phone also using the same kernal 3.10/3.12 etc
Download that rom and port it yourself using the boot.img from YOUR phone using this guide: https://forum.xda-developers.com/android/development/guide-how-to-port-lollipop-based-roms-t3223938
And get it at least booting on your phone, out of loads I've done on MTK phones, 95% boot up first time, 50% of those have no issues, the other 50% have issues with cameras/wifi/video/phone that can be fixed literally with trial and error of swapping files from your stock rom to the new rom, can take hours/days of trial and error or could take minutes.
Have fun
EDIT: try to use a custom rom from a brand you have at least kinda heard of, doogee, walton, infinix...etc to make it more likely to work well.

Thank you for your response!
After few hours of research I have found many ROMs that are applicable for my phone. The thing is, I want it to be and look as close to stock android as possible, and as close to most recent version as well.
But still I have few questions:
1)Am I right by saying that kernel 3.10.72 is suitable only for android 5.x?
2)Is it possible to put android 6.x or 7.x?
3)If it is do I need to ugrade kernel?
4)Is it possible to upgrade kernel?
I really hope it's not too much to ask from you.

Your phone is basically the same as mine, and sadly the kernal has to be the same for every custom ROM, there are no kernel sources so no custom kernels, which means we are both stuck with lollipop
The infinix hot 2 for example, is the same MTK chip and was released with lollipop and kernel 3.10 but then infinix released a stock marshmallow upgrade, with a stock 3.12 kernel so they could get a custom 6.0 rom which im 99% sure we will never get.
If you go here: http://www.needrom.com/author/robneymcplum/ this is me on there, where I have ported the best 5.1.1 roms with our kernel. You will need to port to your phone, which is literally just swapping about 10 files from your stock rom so make a backup of your stock rom or find stock firmware, and get the files from there and use the guide i already posted.
Hope this helps. And if you have never done it, its way, WAY easier than you think it might be

Help with flash a new rom...

Hello everyone I have a question to ask about the customization of my Galaxy SII GT-i9100 ... I followed the guide present in the Carbon Rom thread for the flash of the device and everything went well...now I have the TWRP with the Rom, which is not a splinter anyway, so I would need to try others, as I realize that Android 9 is a little too much for the Galaxy SII. Unfortunately, after flashing roms like Lineage OS 14, the device gets stuck on boot animation, but it is not the only Rom that does so. Can anyone explain to me how to possibly install different roms, since unfortunately I did not understand the mechanisms that underlie the modding of the Galaxy SII? Between Pit files and kernels to flash with Odin, I am a little lost xD Also I would like to know if, by flashing the stock rom with Odin, there is the risk of brick to start from scratch, without flashing the pit or anything. Thanks

hmmmm it is becuz there is rollback protection so once you try 9, no way back to 7.1 or so. restock will just brick emmc.
idk about what rom is good
Samsung's official firmwares are much more stable for GT-I9100 rather than custom ROMs for it. So, there is almost no reason to install the custom ROMs.
Now you have to go to a good repair shop (preferable official Samsung's).
