[Q] Question about roms/kernels/etc...

Good day everyone,
I have done my fair bit of reading in the past few months since I got my first android device (X10) when it launched (sold it 3 weeks later... lol) and since i have been browsing and reading posts after posts on diff. phones, after i had sold my X10 I was very interested in the EVO 4G due to screen size was on then verge of buying it, then I started working for Bell and the SGS came out, and I was sold.
So now I have an SGS i9000M, all this to bring you guys to my questions... general yet specific.
I started reading about roms/kernels/mods/etc... when I first got my SGS and took a dip and did my first flash with stock SGS Froyo 2.2 rom from another region, since it's still not out here from Bell (cell provider in Canada). when Bell UGJK3 came out, I jumped to that.. and finally, when Doc released UGJK3 1.x.. I said wth, let me go crazy and try one of them custom roms.
.... one word to describe it... WOW....
I was amazed at how smooth, fast, responsive the whole thing became. Needless to say I was hooked. Never would I go back to a Stock rom.
Now onto my question (if you're still reading, thank you)
I'm reading a lot about roms and kernels, so I did some research but I still have some unanswered questions.
1st) I read about a kernel K10x either 256 or 500, can someone tell me what that kernel is oc'ing? I have very good pc knowledge but phone wise = 0, on pc when you oc,. you can either oc the bus speed or the multiplier, obviously it's not the multiplier, so by that logic it's the bus speed, if default is 256, means multiplier is 4, since cpu is 1ghz, but then if it's oc'd to 500, means we're running a cpu at 2ghz?
Please someone clarify and clear that confusion for me....
2-A) I'm using Doc's 1.x for Bell because of the MODEM and CSC, I wanna try diff Doc's roms, like v9 or even other roms altogether, like ultimate etc...
Can I use flash any rom, and then with Odin flash, the modem and CSC file from Bell's UGJK3? will is break the rom? or would it still function perfectly but would have the proper APN once I change the CSC in the menu to BMC and allow for the proper frequencies usage (such as 850)... which brings me to part B of question 2...
2-B) I know when you change the CSC or do a hard reset everything gets flushed/wiped, if i have a custom rom installed and do that (a hard reset or change CSC) will the rom still work the way it was originally but with the added software/bloatware from the CSC, meaning will it still be optimized, snappy, and everything else that goes with it, or does it revert it back to "stock" rom, would I lose say my zipalignement or would the rom become odexed etc...
3) Regarding custom Roms, is it OK to flash say Ultimate 3.0, and then flash YA-OK Kernel? so that the rom would use that kernel if for me I find it runs better that way (regardless if Ultimate uses YA-OK to start with, it's just an example), or say Doc 1.3 Bell, using XXX Kernel. is there any incompatibilities, does a Kernel have to be modified to work with a specific rom etc... Also if say it's possible, do I flash the rom first and then Kernel, or vice versa.
If you're still with me, I appreciate your patience and if you take the time to answer, you have my kind regards.
Thank you in advance,
Rodi

no one can answer these q's?

You would be well off to learn a bit about forum searching. Don't expect others to do your research for you.
1> -256, -500 indicate the 'refresh rate' of the kernel. It's a rate in hz, and doesn't represent an "overclock" at all and has nothing to do with the cpu. Some people find 500hz slightly more smooth/responsive, and may have slightly worse battery life. There's lots to read on this topic if you actually care.
2> I have used my i9000m on several modem and rom versions; it depends on the specific rom if it will be compatible with the Canadian market i9000ms; most should be with no problems, and the stock JPx roms/modems have worked fine for many. You can even use a JPx modem and still maintain 850mhz if you change the settings in the *#2263# Band Selection menu.
Note: I personally would stay away from odin with these phones, as there seems to be some kind of sd corruption (I've had to get a phone repaired, as have many others). Stick with 2e/CWM.
2-B> A factory reset takes your phone to the base firmware state. If you're using a full firmware rom, it should revert back to the options in said firmware. The CSC only specifies extras afaik, and shouldn't override any of the rom's base settings.
3> As long as the kernel is compatible with your current config, it'll work fine. I run Doc's Barebone UGJK3 w/ UGJK4 modem and k10i kernel. The only thing you probably need to be warry of is lagfix and advanced option compatability between kernels. If you disabled advanced options/lagfixes first, most other kernels will probably install just fine. Flash the base rom first, then everything you want to override (e.g. kernel/lockscreen/skins) after.

Couple of Q's before I do a first flash...

After many joyous years of flashing ROM’s onto my HTC TyTN II, I’d quite like to do the same with my Samsung Galaxy S. Before I do though, there are a couple of newbie questions that I haven’t been able to answer via the search facility:
1. Can I back up by existing ‘stock’ ROM before I start? (I’ve checked the stock firmware and mine isn’t on there)
2. Do I need to root the device first, or is this done as part of the flashing process (or not done at all)
3. Are there any downsides from flashing these ROM’s? Other than the potential risk involved, do I lose any features/functionality?
I’ve tested the three button mode and works fine on my device. I think i’m ready to go but just want to clarify I’m not missing anything...
My device info:
PDA: I9000ADJP5
PHONE: I9000ADJP3
CSC: I90002UJP3
Build: 2010.11
Many thanks

Not sure about your first question, but I think it's still possible to fool kies so that you can revert back if you really had too, check on this if it is really important to you.
No need to root first, either flash a stock rom and root later (if you need root) or just flash a custom rom that is already rooted.
No feature loss, other than maybe losing some carrier bloatware. The new JPU rom makes your phone feel like a completely different device. Check out the custom roms in the dev section too.

Fantastic. Thanks for the information. It isn't essential I get the stock ROM backed up really. Just being over cautios?
I was going to start with Darky's v5.2 Gingerbread Edition ROM which looks like a nice change from the Samsung stock experience.
Sick of the lag now - can't wait to see if it does as much for my GalaxyS as the WinMo ROM's did for my TyTN

Don't forget to flash jm8 first. Its like installing a big rom for tytn II to clear unused parts of rom. Read darkys instructions slowly. If anything goes wrong its your fault not the instructions

Advice

Good evening,
I usually use Windows Mobile devices so very new to Android, but my girlfriend has recently purchased a Galaxy S from Three. I have tried looking in the FAQ's but there is that much information I am feeling a little confused and dont want to go bricking a £380 phone.
Anyway, the phone has Three's customisation on it and it's not good to put it simply and I am wanting to return the phone to stock ROM or possibly a custom ROM.
The phone is currently running Android 2.2 as it updated when we first got it using the Samsung Klies.
Please can some of you offer advise on where to start with this as I presume I will need a backup of the ROM currently installed.
I've tested the 3 button download mode and that works fine.
Many thanks.

Well with the 3br you can pretty much do anything I would probably flash different kernel which has 2e recovery either speedmod or cf root then install rom manager and from within that app install cwm this enables you to flash custom roms preferably jpy 2.2.1 or just use odin to flash roms that are available from samfirmware again id recommend jpy.

It is worth reading everything you can before you start rather than posting in panic if it goes wrong. You can also break the three button as many have discovered lately to their loss. It is always a risk. So make sure you know wha your doing before you start and remember her warranty will probably be voided by doing any flash.

[Q] irritating ~ Note getting slower

I had posted a similar thread earlier, but it had a different reason and a different solution, yea, KL7 was the solution..but its been a week since I upgraded and now unfortunately my note is becoming slower!!!
what could be the reason. Im on stock kl7 meant for DBT. i had s2 earlier (nw its with my wife) and i really miss the superspeed s2. i have a iphone 4 with me (secondary phone) and now due to timesaving efforts im using more of iphone 4 eventhough i hate the small size. (pls dont call me a iphone fan!!!). i need note's display and size and s2's speed!!
any latest stock rom's??? (non wipe versions???)

ive never used custom rom in any of my android devices..ive following 'fears'
1. will it affect any major aspect of the phone (ive seen many threads like battery issues,wifi issues etc etc..)
2.if later i want to update latest firmware via kies, wil that be a problem>?
3.will i wipe out my data/apps etc?
4.which is the best custom rom available?>

1. Possibly. Possibly not. Depends on the ROM. Usually the ROM developer will provide detailed information about what's working, what's working better, what's working worse, and what's not working at all. It's up to you to find the best overall fit.
2. You'll have to do a CWM backup and flash back to stock in order to use Kies. Then again, that's kind of a moot point if you're using a custom ROM anyway. Usually dev's will bake in the latest/best working firmware into their ROM's anyway, so Kies really isn't that big of an issue. I've personally never had a need for Kies; I've always just used Odin. It's way better anyway.
3. Depends on the ROM again. However, coming from stock to a custom ROM, it's highly recommended that A) you do a backup of your stuff and B) you perform a full wipe (keep your backup data in tact obviously).
4. That's up to you really. What may be the best ROM for me might not be well suited for you. Have a look in the dev section and see what's out there!

[Q] What are the implications of flashing <official> ROMs outside your region?

Hello, first off, I'm new to the android OS, especially flashing ROMs. I did however have some prior experience in flashing other mobiles such as the Symbian platform on my previous Nokia phones.
I would like to try the new Firmware XXLA1 as of now Im using an OTA update kernel version of 2.6.35.7-N7000DXKL3[email protected]#2.
Btw, im from the Philippines and I bought this handset on this country.
So going back to my question, what are the repercussions and implications if I flash the LA1 official ROM from Samsung knowing that its a ROM for "Open Europe"?

if your phone is unlocked (No carrier restriction) you can flash any Stock ROM

Yes, i bought it unlocked. Will the app availability in the market change?
Also, since its an official ROM, would it break my warranty?

I Live in Indonesia, yes samsung Indonesia say it will break our warranty but you can flash it back to KL3 whenever you want to claim it..

Bump. I would also like to know of any important differences between stock roms if any. I live in the US and will be getting my Note in the next day or so and think I will root it but keep it stock and just uninstall any bloatware I deem unnecessary.

I recommend using it for a week before you try any (potentially) warranty breaking mods on it. Get used to it. learn how things work. Then when you start modding you will have a far better idea if the mod has broken something or not.
You can generally flash a ROM from any region, as long as you understand the language. You can flash RADIO seperately, and you would choose one that will work well with your local provider. Lastly, you can manually set the APN settings to lock onto your chosen provider.
Be aware that some new devices have a "binary counter" which will sometimes increase when you flash something. Your warranty may be affected. Spend time reading the forums learning about the issues before you flash.

Thanks! Sounds like a plan

Looking at the kernel version you have, it is safe to assume that we possess the same unit, and yes we have the same roots (oy, kapatid!) as well.
I started rooting my unit after a few weeks of getting familiar with it. Don't worry too much, since i was able to successfully flash root my unit and install CWM (clockworkmod), using the zergrush exploit.
Once CWM was installed, the 1st thing i did was a nandroid backup, just to keep a backup on my stock settings.
After that, i tried flashing custom ROMs, and it worked flawlessly, albeit with bugs. Just follow the steps outlined on each ROM thread and you should do fine.
Managed to encounter boot loops, phone not booting up, etc., but nothing too critical that made my unit useless.
As for your question, the obvious implication is that by flashing custom ROMs, you void your warranty. So, unless you have qualms in losing your warranty, then go ahead and flash a custom ROM.
