[Q] Flashing a rom - Galaxy S II Q&A, Help & Troubleshooting

I have never flashed any rom or kernel.
If I want to flash the latest resurrection remix ics rom, do I have to flash a kernel (e.g. siyah) after flashing the rom?
Android version
4.0.3
Baseband version
I9100ZSLPG
Kernel version
3.0.15-I9100ZSLPG-CL348413

Every ROM does already contain a kernel.
A kernel is the "core" part of the ROM/firmware.
Just flash the ROM.
And only if you feel that you miss something or want some features of another kernel, then flash the other kernel.
But be sure that the kernel is compatible with your ROM.

[Q] Downgrading Kernel???

Guys currently i m on stock GB with francos kernel (2nd October) & want to flash cyanogen 6.5.8....
But it is not compatible with .35 based kernels so is there any way to downgrade to the old kernel other than flashing froyo through kdz....
I searched the whole forum but didn't found anything....
Plz tell me how to proceed??
1. flash baseband
2. flash ROM
3. flash kernel
OR
Any other sequence???
Normally, when you'll flash the rom, the kernel will be included in.
Search a bit for threads about baseband.
So which kernel is included in cyanogen????
& does this mean that my kernel will automatically revert back to old after flashing ROM????
The only way to use mik OS after flashing any 2.3.3 stock based ROM ( kernel is not the matter here ) other than KDZ is to flash a BASEBAND FIX given in the mik_OS main Thread but I think mobile data is disabled in that FIX. So, I think u're stuck bro without KDZ-ing !

Only stock based kernels like doomkernel or thkernel work with fera labs Rom.
You need to flash the recommended kernel in every ROM. The recommended kernel is mentioned in the OP

[Q] Trouble with rom

Hi guys !
I'm new in this section, and my Galaxy S 2 is just rooted. Otherwise it's pure Samsung Rom.
I was looking for a way to install Omega Rom, but i'm kinda lost...
I've already read many tutorials, but...
The thing that i can't understand is, should i flash a compatible kernel, and then the rom i want, or is the kernel included in rom installation ?
Thanks in advance.
Cheers !
Hey,
Look at Omega ROM thread to see if it has included Kernel.
If it has a Kernel included, go ahead and flash it directly otherwise flash siyah kernel and then Omega (providing that they're both compatible, which i am sure that they are)
Cheers.
PS. Welcome to Galaxy S2 world!
Thanks for your reply !
In Omega thread, it says :
Inside Omega v20 Jelly Bean 4.1.2:
Based on firmware XWLSD Android 4.1.2 (Date: 31/01/2013)
Kernel: PhilZ cwm6
Modem XXLS8
CSC Multi set to EUR
So, kernel PhilZ is included in the installation, right ?
But, XWLSD mean that i should switch to firmware XWLSD before flash, or it's just in indication ?

No that means omega rom is based on latest stock LSD..And yes philz kernel comes with the rom. All you need is a safe kernel like siyah or dorimanx which has a proper CWM recovery
Thank you guys ! Will try to do it ASAP !
Cheers !
Well actually Philz is also safe kernel.
But if you want to switch to Siyah kernel or whatever do that after flashing the ROM

So, can i flash Omega Rom in stock recovery, to switch directly from Samsung kernel to Philz ?
With Omega rom you will get Omega files app and you can dload there kernels and other stuff. Kernel section there is links to the philz, jeboo and siyah kernels. Just try there and use that what is best for you.

Do not flash roms in stock recovery. Specially if you are on ICS 4.0.4. You might brick your phone. If you are on ICS flash a safe kernel like siyah v5 or dorimanx kernel via ODIN. Then you can boot into recovery, do a wipe data/cache and install omega or whatever rom you want

First flash a custom kernel, and from that point you can do a full wipe and flash roms.
Thank you all for your help guys !
Cheers !
Can anyone of you point me to the right kernel here please : http://dorimanx.shine.sk/ or in PhilZ Kernel thread.
Because i'm lost, there is to many choices and i don't want to blow up my phone.. I know that it should match my rom version, but match my actual rom, or the rom that i want to flash ?
Or more simplistic, can i flash it over stock kernel ?
Cheers !
EDIT : Kernel_Siyah-Dorimanx-V8.2-[17-35]-[05-03]-ICS-JB-SGII-PWR-CORE.zip is the right, i think... but need confirmation

Depends on the base of your mini Rom.
Stock ics based you can use any ics based kernel like suave, lupus, etc.
For cm based you must use cm kernels.
Yes you flash kernels in fastboot mode with flashtool.
send from my mt11i with cm10 unofficially (TheDarkDefender build) on fusion kernel v5

There are two miui version in this thread.
1. v4 which ist stock sony ics .587 based
2. v2 which is cm7 based.
For v4 you can use any compatible ics based kernel.
Look at the stickys and you will find the kernels listed.
On my mind are stock sony kernel, advaced stock kernel, suave kernel, lupus kernel and nightelf (aliance) kernel.
If you are already on sony ics rom you can directly install miui rom.
If you want more kernel features than you must flash a custom kernel. To do so you have to unlock your phone bootloader.
V2 is cm7 based as already written. To try it you must unlock your bootloader and flash the provided kernel that comes with the rom.

Yupp.
V4 ist .587 based and works with stock kernel. You are limited to stock kernel features. If you want more like overclocking, etc you must unlock your bootloader and flash an custom ics kernel.
With a locked bootloader you are limited, with a unlocked bootloader you are free!!!

Flashing over custom kernel

Hello guys, I'm on custom AEX treble build with Franco kernel.
My question is: can I flash other custom ROMs over custom kernel or will I have to go back stock kernel before flashing other treble build?

I am going to assume that you are going to do a clean flash/factory reset (deleting apps and their data). When you flash a rom it flashes a kernel so custom kernel is gone.
Although you didn't ask I will state it anyways. If you are trying different custom kernels you need to flash back to the roms original kernel before flashing a new kernel.
