[Q] When flashing a new ROM does it change the kernel also? - Android Q&A, Help & Troubleshooting

I hear that some kernals are better than others and I assumed they change when you change your ROM but I'm not sure. I feel like I would have better battery life with a better kernel.

No, changing your ROM doesnt always result in changed kernel. Also depends on Stock or Custom ROM. Stock Rom flashed with Odin will probably change your kernel to the one provided in the ROM package, but if you install custom ROMs through recovery then your kernel will not change.

Which ROM to use?

I'm currently using Lite'ning ROM and since the developer went MIA I'm thinking of changing to another ROM. I tried ToxicROM but dislike it due to various reasons...
One of the reasons why I wanna change is because my SGS2 often hang / restart / lag kinda problems which seriously annoys me..
Try one of the needs new stock roms.

Try = Install one of the latest/newest STOCK Samsung ROMs like KL1
That was the advice given .
Read the rom descriptions in the custom roms sections and decide what you want is another choice ,

I'm not a big fan of the stock ROM.
Go for CriskeloRom or CheckRom RevoHD. In my opinio, they are one of the best ROMs.
Hope this helps

I'm using CheckROM v4 with siyah kernel v 2.4.2.. My phone is very smooth, with good battery life and stability... I use this kernel only for bln, because the phone is good even with default settings..you can also try speedmod...
Hope this helps!

Stock ROM OC i717

Warning! Super noob question:
I was just wondering if my stock ROM can be over clocked. I have SetCPU but it appears that the max values have Lready been set as high as they will go (1500 mhz). If I want to go higher do I need a custom ROM or kernel? I just rooted my Note and I've never done this before. Honestly I don't have much of a clue as to what I'm doing lol.

U need a custom kernel just flash one that is compatible

You can do it on the stock ROM, you just need an OC kernal. So you can either flash the kernal through Odin, or flash CWM, then flash the kernal.
Sweet. Thanks guys. I got tired of trying to mess with the over clocking and just flashed the ICS ROM over. Its buggy.. but I suppose it will do until the legit one comes out.

help please....

I don't know what info you will need so please just ask if I'm to vague.
I upgraded to ics but couldn't find a root version that would give titanium backup root access, when I tried to flash back to a previous non ics ROM it would get stuck on boot screen, my only option was to reflash ics and restore a backup which was Android 2.3.6.
Now I have severe battery problems, my Baseband is - I9100XXLPB AND KERNEL is XWLA4 running CHECKROM6hd.
I'm stuck for what to do, any advice would be much welcomed, to be honest I'm not sure what question I should be asking.
I want to remain on CHECKROM6hd with jk deluxe settings with full root access, this is important for me, the Baseband and kernel look to be the ics versions but flashing gets me stuck on boot screen, only ics flash will work :/
any help advice would be great, thanks guys...

A huge number of things factor to battery.
LA4 is the kernel for GB. No ICS kernel would work on GB, it would probably prevent the phone from booting up if you did flash a ICS kernel on a GB rom.
It would probably be best to do a factory reset or even reflash the rom after a full wipe. (after you back up your data)
If you dont want to do any of that, just install betterbatterystats (can be found searching xda forum for free)
Install the app, and use your phone like you do and then check the app to see whats causing the drain.
what is the baseband? I don't understand what the baseband and kernel really do, how they relate, are they a mismatch?
thank you

Baseband is the modem, it is completely independent from the kernel and ROM, you can use ICS modems on GB and GB modems on ICS without any issue, if you are having reception or data speed issues you can change it by flashing one in CWM from the modem thread, if you aren't i'd just leave it alone.
I changed the Kernel to XXKI4,
The battery seems to be behaving as normal again

Can I take this opportunity to ask what recommendations any of you might have for a good baseband, kernel and build number, for a jk deluxe settings ROM that is battery friendly please

Nandroid backup is not backing up the Baseband, that was why you did not get back the Baseband of of your previouse ROM (Checkrom). you will be having the Baseband of the last flashed ROM...
Are you sure you have flashed the Kernel XXKI4 on the rom XWLA4 (checkrom).?
I think you mean to say is "BASEBAND" not the "KERNEL"
yes baseband lol, but it was a 'kernel' from kitchen pro I used to flash/install it....... can I blame autocorrect?
Me?
I'm English...... as in England.

i think ki4 is a good baseband(modem,radio)and as far as kernel there r lots of good ones like siyah,neak,redpill.....first decide gb or ics...c which is best for u?cause many don like ics an reverted to gb.....but all depends on how u use....remember every phone is diff in thier own way.....

Where can I get the stock kernel?

I realised why none of the roms would work without flashing stock kernel cuz I deleted my stock backup that had my stock kernel this is the only thing that makes sense but I may be wrong the roms prolly come with the stock kernel If I'm right is it possible I can get the stock kernel?

always upto u 4 the choice
Stock kernal is best for gaming I think....though our developers are great to give us two kernal.
...so try out both...both have different taste

not agreed... I've checked it myself.... i used antutu before and after flashing the kernel. and the results were like before flashing 139xx and after flashing 123xx ...
you can check it...the only thing i liked was dt2wake
