[Q] Question about flashing ROMs and Kernels - Android Q&A, Help & Troubleshooting

I was just wondering if you flash a new ROM is it necessary to flash a kernel right after? I just recently flashed the ICS port on my Nexus S and I was wondering if I have to flash my kernel again. Thanks

No, you do not have to flash a kernel after flashing a rom. Plus, using that rom (which is in its very early stages), it's not recommended that you flash anything on it.

every rom has its own kernel do not flash another one unless u got problems with stability/battery.

Cool as in not overheating ???
a wipe and flash of stock rom will remove custom rom .
Root and custom roms void warranty and have a slight risk of bricking the phone .
But are usually recoverable .
You need to read the faqs and guides and understand the CM9 instuctions first .

to flash cynogen rom first u have 2 root ur phone please find the thread in original devlopment section regarding the same
u can reflash ur stock rom by dwnld the releavant .tar file adn flash the same thru odin
You can re-flash the stock rom, but just be sure to know which one is your stock rom. Go to settings, about phone and record the info there to be safe. Also back up your current rom using CWM.
There are always some risk in flashing a rom. Some people dont read instructions and cause problems on their phone, some people flash a rom not built for their phone (i9100 VS i9100G), etc.
Yeah i have rooted my device with cf-root. Thanks guys , i'll read some guides about cyanogenmod and flash it.
If your are currently on GB stock rom, Cyanogenmod developer recommends to install ICS bootloaded first,
You should be able to reflash your Stock ROM veriosn from ODIN, as well as custom roms from CWM...
What is bootload? o.o
My current firmware is ICS LP7

No they say to have below some specific ics boot loader, no mention of upgrading your gb boot loader, unless they changed it.
Plus I yet to had any issues with the latest ics or gb bootloaders..

I think he meant boot loader.
But since you already have ICS, you won't need it. Just take the latest CM9 nightly (or ROM based off it), and flash (you'll have to wipe cache data and dalvik too eventually). Make sure you make a full backup of your current stock ROM through CWM as well.

I refer this guide actually : http://forum.xda-developers.com/showpost.php?p=20841817&postcount=1
I dont know its outdated,
as others are sharing their experiance that you could flash CM9 straight away from your CWM since you are already on LP7 with ICS Bootloader.....
I don't get it... What is a bootloader?. I mean when i flashed with ICS LP7 i didn't put a file on bootloader. I just loaded the PDA .tar file and flashed it..
Soo that means that i have to reflash the stock rom with bootloader?

I dont know the ICS package you flashed had an ICS Bootloader already...
I just gave you the link for Original CM9 developers guide...
Just wait for others recommendation who have already flsahed CM9 from CWM....
Hmm thanks . But i have read in the guide that i can flash it with odin , do i still need the bootloader?

Flashed Using Odin, Want to Install JB... Now what?

So real quick....
I rooted my phone with ODIN last night, so I'm still running AT&T Rom and Stock 3e. I am trying to get JB installed but don't know where to go from here. I need to get Clockwork Recovery right? If so, how can I get that on my phone? I did read I should not used ROM MANAGER!
Sorry for the stupidity! I got JB on my last Galaxy before it broke I'm just confused because I did it a different was last time. Thanks for the help!
just flash a custom kernel with ODIN. That'll give you CWM recovery. then you can flash whatever you want.

Ok, is Odin 1.85 sufficient (or is there a newer one) and then can I just flash it with Siyah 4.1.4?
IDK much about Odin. But if it worked for ya the first time it should be good.
for the kernel, you must find one in a format Odin uses and not in the normal .zip which requires CWM recovery to flash.
Right now .tar is the only one that comes to mind for Odin.

I would flash a kernel that is compatible with whatever ROM you have currently. Then flash a JB ROM from CWM . Flash Siyah after you have JB if that is the kernel you want. I think you would get boot looped if kernel and ROM are mismatched.

Okay cool. I know this might be asking a lot but can you just link to me a Kernel that will work with the ROM I have? It's still the AT&T Stock Rom 2.3.4 with Baseband I777UCKH7 and Kernel 2.6.35.7.

Take a look at the guide which is the top link in my signature. It will give you a little more detail on what you want to do, and has links to the available Gingerbread kernels.

the only point in flashing a kernel compatible with a ROM, would be if you wanted to boot into the ROM.
Yes, flashing a kernel meant for a different version will most likely bootloop.
You can flash any kernel you want if you have no intentions on booting the system.
Recovery inside the kernel has nothing to do with what ROM your running. Will always be able to boot into recovery. Or **** broke
I give you lots of credit for reading not to use rom manager!

If you use Mobile Odin you can flash a custom kernel that will install CWM and then flash a custom ROM with CWM. I do this so I do not mess with the flash counter.

It sounds like you're taking the same route I did to root my phone. I first flashed a rooted, stock ICS ROM, then I flashed the Siyah kernel using Mobile Odin, then I eventually went on to flash a JB ROM (SuperNexus) using Mobile Odin. I'm sure I could have skipped that step of flashing Siyah because SuperNexus flashes a CM kernel anyway, but I kinda didn't know what I was doing.

[Q] Flashing custom Kernel after ROM update?

Hi there,
So I've been looking into flashing custom kernels, and I can't seem to find an answer to this question. Basically, I'm wondering if the kernel remains after installing a new nightly, or do I have to reflash the kernel every time the ROM updates?
Thanks

Flashing Custom ROM on Mido

hello, i'm new mido user, i'm using ido too. i wanna try flash custom rom on mido, is it necessary to flash firmware before flash custom ROM, and what's the purpose we flash firmware? bcause in ido, we don't need to flash firmware before flash custom ROM. I'm still looking for the answer of my question, i hope someone can help me to explain it, thanks
Hmm, what do you mean by firmware?
The steps are:
1. Unlock boot loader
2. Install custom recovery (TWRP)
3. Install custom ROM
i've read some threads of custom rom like Candy ROM, and they said we should to flash firmware. that firmware is cm14-mido-firmware-20170430.zip i mean

Oh that. That's only required to flash firmware when you're coming from marshmallow based MIUI only. Otherwise no need.
The thing is if you flash firmware before installing Rom, it's not an issue. You're good to go. You can find latest firmware zips from this (https://forum.xda-developers.com/re.../firmware-firmware-update-2017-08-04-t3651537) thread, huge thanks to @Zile995 for the updates!
