Finding out what ROM was installed

Hey
I used to have a nice ROM installed with a kernel that allowed overclocking. I would run my shift at 1.5Ghz and was really happy. Then when Gingerbread was coming out, I decided to flash a Gingerbread ROM because I was just excited for 2.3
Now there were not kernels for Gingerbread ROMs at that time. So formatted/wiped everything from my device using Clockwork Recovery. Now here's where I have a few questions:
After I wiped the entire device, when my phone booted, it seemed to have 2.3 installed so I assumed that since there was an OTA update for Gingerbread, it must have gotten updated somehow. I want to find out whether I have a custom ROM with 2.3 installed or is it a regular Gingerbread stock ROM that's on my device?
I would like to find out what kind of ROM is installed on my device right now and do whatever it takes to be able to flash a kernel that allows overclocking, because going back to 800Mhz from 1500Mhz is just not doing it.
I would also really appreciate if someone gave me direct links to a custom ROM (since I understand at this time it is impossible to flash an overclocked kernel, since HTC has not released official Gingerbread source code yet) with a flashable kernel that's completely stable and allows overclocking to 1.5Ghz.
I really don't care about the whole Cynaogen Mod etc, because I use LauncherPro anyway and from what I understood when I was reading about Cyanogen Mod, it doesn't change THAT much other than adding a little bit more functionality and mainly focusing on changing the phone interface, which is completely irrelevant to me.
Thank you in advance.

If you just did a wipe and didn't flash anything, your still running the same ROM as you were before the wipe. If you go into setting > about phone > software information > more, this will tell you your current ROM (build version). If you would like to continue using Sense but want to overclock I would suggest MikShift 1.1, otherwise I would suggest the Shift Deck ROM. Both can be overclocked with several different kernels, just do a little reading through the dev section to see what best suites you.

Disregard, just typed what crump said but he beat me to it!

Need some more info.

I see on this site about flashing new roms, the 3.1 android and others and the Kernel.
Is their 2 different rom chips one for the kernel and one for the OS..?
When I flash a custom rom does that change the Kernel or do they have to be flashed seperate.
Is there certain custom roms that have both..?
When getting a custom rom do I need to get a new Kernel..
Do the custom roms have both, Little fuzzy here..?
Thanks for the info.

Kernel and Rom are 2 separate flash...
most custom rom dev already takes care of the kernel for you with their custom roms ( kernel built in ... 1 flash takes care of both )...
but if you're interested in flashing a custom kernel... just make sure about its compatibility with various roms.
read thoroughly in custom rom & kernel's threads 1st post... they usually let you know what's the requirements are...etc

Thanks so much, that clears my mind and makes things much easier.

Plea for One Last Missing Kernel

Hi Everyone first post since owning my i9000 since it came out and have followed xda since then. I would like to thank all the devs for everything they have done for this phone as the amount of improvements we have seen.. have been nothing short of brilliant... many thanks.
I am currently running aokp and it's excellent and also have cwm backups of other Roms on the phone. These are all Mtd Roms.
I have looked all over xda and it seems to me that we could convert the many good gingerbread roms to run in the new MTD partiton without reverting back to odin and wiping the phone only to have to do it all over again if we want try the many good custom and stock gingerbread Roms.
The flexability we would all gain from being able to flash other Roms without reverting back to odin would be great for everybody ... but there isn't a kernel to do this unfortunately.. I know I've looked back to the begining of all of the threads and can't find one ... or make one.
I have researched how these roms could be converted to run in the MTD partition and have a good idea how to pack them to run, I am not a rom chef or a dev so it would be just a re-pack. But the rom chefs would do this themselves if we had a touchwiz-MTD kernel made for this task.
I will not show how you go about re-packing a rom to run cause everyone would
try it without the necessary kernel and probably mess up their phone .. so best not.
Could we have one last missing -link kernel just to square the circle and run a stock samsung gingerbread rom in the MTD Partition... we would the be able to keep these as cwm backups and switch to any rom we like.
One last plea for the end of life galaxy S . . Great Phone

[Q] Rooting, flashing custom rom but necessary to flash a kernel as well?

Hi,
Quick question I am still having trouble wrapping my head around the concept about kernels. I am planning to root my nexus 4 and flash a custom rom (purity rom) but am i required to also flash a custom kernel? Or am I suppose to leave the kernel as is?
Thanks!

Depends upon your requirement .
As an example i use Fast USB charge a lot and is not available in any custom rom .
I also use Headphone volume boost which is yet again a kernel level change.
I would suggest you to use a custom kernel since it also gives better battery than stock .
If you are happy without it then forget about kernels . And in case u plan on flashing one make a CWM backup just in case.,

You could if you want to since you're already flashing custom roms. However, most custom rom come with custom kernel, so when you flash a custom rom it will replace your kernel with it's own. You can manually flash back your stock kernel if you want, using fastboot, but there is a flashable package as well in the Dev section.
Just know that due to codes and drivers, different kernels work with different roms. If you flash a 4.3 kernel to a 4.4 rom, it might lack certain necessary driver, such as PRIMA, so your wifi will no longer work. (You can fix this by flashing dePRIMAtor). CyanogenMod use Code Aurora Forum drivers, so if you use a kernel that doesn't support CAF, the screen colors will be messed up (you can lash a colorfix package which replace it with the non-CAF liboverlay.so).
A lot of people get wrapped too far up into flashing kernel and thinking it determine everything (performance + battery life) in their phone. As much of a heavy flasher that I am, I am willing to bet that you generally get the best battery life and stability just running stock. I did my own trial for this, with stock rom and kernel, the phone staying cooler and screen on time was longer. This is just my personal experience, it varies for each person.
But I mainly use custom kernel for features. Such as kernels that incorporate Faux color and sound, this allows changing their settings for much a better screen color and making the speaker louder. I also use the sweep2wake/sleep feature to turn on and off the screen.
If you intend to use custom kernels, I recommend using TricksterMod, it's the best app for modifying kernel settings.
Also just to mention this ahead of time, it's against XDA rules to make threads about what is the best rom/kernels.

First time flashing a kernel, some quick questions

Hi everyone
I have a rooted stock Galaxy S4 I9505 (4.4.2) and TWRP installed. For the last few weeks, my phone had a lot of kernel wakelocks which I couldn't stop. This could be fixed by installing a new kernel, right? I wanted to try that anyway.
I think I read the relevant FAQs, but this is my first time flashing a kernel, so just to be sure I have a few questions:
Does anyone have experience with the KT-GSG4 kernel? Do all custom kernels have the basic functions of stock kernels (plus some features), or will I lose some functionality?
Can I just flash the kernel, without changing the stock rom and keeping my files/settings etc.? If I do something wrong, can I just restore via nandroid backup?
Do I just have to go into TWRP recovery, click install, choose the kernel zip file, install it, wipe caches and reboot?
Thanks a lot!

Ktoonsez is a great kernel dev. So the kernel should be fine.
A custom kernel generally offers more customizability. I don't know what features you might from stock kernel you might lose.
If the kernel is for touchwiz, then you can probably flash it on a touchwiz rom. Just make sure it is for the same android version.
I haven't flashed any kernels on a stock touchwiz rom so I can't tell you the flash procedure. It may be different from custom roms due to knox and other stuff.
