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.

In an effort to get BLN back on my I9000M, I'm trying to decide if it's worth switching to the SpeedMod kernel. Since I've got my I9000M back from repair and upgraded to JL2 it's been running flawlessly so I don't want to mess with it - but I do want BLN.
So JL2 users with SpeedMod - any problems so far? (and which version of SpeedMod are you using?)
I'm referring to this SpeedMod, btw:
http://forum.xda-developers.com/showthread.php?t=822756
I would definitely switch to SpeedMod. It's a great, fast kernel with a ton of options.
It wouldn't cause the SD card to die, if that's what you're thinking, because by flashing the JL2 firmware you're flashing the secondary boot loader (Sbl.bin) which fixes the issues with the SD card. The kernel is like an entirely separate entity than the sbl, which means it won't brick.
So, go ahead and flash it.
Thanks for the feedback. I wasn't worried so much about the internal SD as I was about things like WiFi battery drain which seems to have become an issue in some of the 2.2.1 releases.
But since I'm not too familiar with Android/Linux development, I'm don't know if it has more to do with the JP* firmwares or the kernel itself.
I've been running it with speedmod k10k all lagfix/speed options disabled (I don't need them, this rom is quick!) and my phone is working like a champ. wifi/gps off, push/pull on w/ hsdpa, I can go just about two full days without charging. With wifi on and gps on plus everything else, I can go about 10-12 hrs.

I was under the impression that the sd card issue was a bit deeper than just flashing a new bootloader. Is there a thread with more about this? i dont want to brick any more phones, and if flashing JL2 will correct the memory issues, i'll gladly go back from jpy. and is there any way to flash the SBL (if it in fact fixes the sd corruption) without changing anything else? ie: sticking with my jpy without a whole pile of flashing to jl2, then back, etc.
Thanks for the input. Running now with all the recommended tweaks but no lag fix... Maybe a bit more fluid in the ui, but honestly jl2 was so fast to begin with its hard to tell All i really care about is that i got bln back.
Will be watching battery overnight with fingers crossed.

I too would like a little more official information about this, and whether the new SBL fixes this. As this seems a little to quick for Samsung to say they've fixed the problem. Who knows that would be a great not to live in fear each and everyday I use my SGS
I'm so new to this - is this easy to do ? to flash this rom ?
where's the best way to start, you tube? is there any reccomended tutorials ?
I have a SGS from bell, it's my 2nd one. I haven't upgraded to Froyo yet b/c I can't connect to Kies. Should I just flash instead ?

Running JL2 + Speedmod + lagfix, phone is fine so far. BLN was causing the touch aspect of my screen to not work so i couldnt even unlock it. havent had a change to fool around with it though.
Been running Super Optimized Kernel instead of SpeedMod in my custom ROM, and I've noticed that its been much faster. Gonna stick with it for now.
Hello,
Sorry to sound like a complete noob in advance!
I have a new Samsung Captivate I896 on Rogers in Canada. I have ryans OCLF lagfix installed atm but i'm really interested in flashing this rom (will be my first one) and am wondering if it will work on this phone.
Also, is it just a backround fix? Will I still be able to use launcher pro, and will my phone still look the same with Froyo 2.2?
thanks in advance!

Speedmod is not a ROM, but a kernel.
As to your other questions, you have a LOT of reading left to do.

Agreed. Just to be save do alot of reading before attempting anything really lol. There are stickies in the Development section start there.
Ok so I did a little more reading. I896 and I897 are essentially the same. I'm not flashing a rom, just a kernel, so there should be no issue with the 3G problem mentioned in the wiki.
It won't change my rom or anything about the device other then how the filesystem works.
Thanks!

Hi, I'm pretty new here too, and I have to tell you that know one will give you a straight answer. There's a lot of' tribal knowledge', and it seems that people would rather teach you how to unbrick your phone than to flash it without issue.
First of all, hook up to Samsung Kies and update your phone to Froyo. If you are on Rogers it's an official update, don't worry about flashing any other roms yet.
Next, Use the option in the OLCF to unlagfix.
Next, you will need to root your phone. OCLF is practically obsolete, as the developer does not update anymore. Your best bet is Superoneclick. Read all instructions first. It is very easy and effective.
After you have the phone rooted, you can now install Titanium Backup. This will save all of your apps, contact info, settings, virtually everything on the phone, it will save them to a folder on your external SD. drop and drag this folder to your desktop in case anything goes wrong. I never had a problem.
You should backup your kernel. I used Neldar's SGS Kernel Flasher. It will save your kernel as an 'update.zip' in your root folder. Drag this to your desktop and put it into a folder called 'i897 orig kernel' or what have you, in case something goes wrong. I never had a problem.
Now you can flash SpeedMod. The developer's website, which is linked to in the thread's first post, will walk you though it. You will first need to install ODIN. The SpeedMod developer has a step-by-step on how to flash SpeedMod using ODIN on the developer's page. Make sure you choose a Speedmod Kernel that is intended for the Captivate, not the I9000, and that you chose the one for ODIN, not the ClockWorkMod version. Follow the steps in the Developer's page.
When you have done that, reboot into recovery mode and you should see Green Text. From here you can enable the lagfix and other tweaks. use the volume keys to select the option you want and the power button to select. under the options, it will show you which tweaks you have enabled or disabled.
Remember to select the most stable SpeedMod release, the one that is posted in the Forum (K12U-T4) is a TEST VERSION, hence the 'T'. The latest stable version as of this writing was K12T, as posted in the developer's page. I have had great results with this one.
You may find that you don't need to flash a custom ROM, I have found this setup very satisfying.
Good Luck!
Wow,
Thank you so much clemmie! That's was succinct and very helpful, especially the part about the proper way to back up my stuff.
I uninstalled OCLF just now, and it seems my phone runs at the same speed (aka fast) as it did with the lag fix installed!
Going to flash this kernel tonight or tomorrow, I'll let you know how it goes.
Thanks again!
Good to hear. There would be a lot less smoke and mirrors if people would just be straightforward and post step by step instructions with links, to give people what they want. I hope what worked for me will work for you, and I encourage you to share what you learn as well.
Kernel flash done! Screen is initially very different looking thanks to the amoled mod. Success! Backed up, thanks for all the help.
hey clemmie,
i heard that there's some issues with voice quality due to the Speedmod kernel being initially i9000-based and that it's recommended to flash a i9000-based modem. Are you having any issues with using a stock i896 modem or do you recommend something else?
Yeah, that is true, but I haven't had any problems with the stock modem. The phone works as well in-call as any other I've owned. I wonder if there is a difference between the AT&T build vs. the Rogers build. It seems that it's the AT&T folks that have issues.
Hi,
I've been wanting to do this but I'm a bit wary if this will put the ATT splash screen on boot as well. Also, I like how my phone looks like now with ADW launcher and beautiful widgets installed, I'm just wondering if installing this mod would change my appearance settings too.

Are you on Rogers? Earlier versions of the SpeedMod kernel had the AT&T splash screen, but newer versions have a simple black screen similar to the stock Samsung boot logo.
Installing the SpeedMod kernel will not change the configuration, apps, or settings of your apps. There are some settings that you can tweak in recovery mode but they are mostly file system tweaks. You will however notice that screen resolution is sharper. Your phone will run smoother and more efficiently with better battery life. You can still flash any custom or stock ROM with SpeedMod or without SpeedMod.
Yes I am on Rogers. However, I can't seem to find the stable version K12T that you mentioned on your instructions from the developer's page.
If you click on the hotlinked 'SpeedMod' in my 'tutorial' post, it will take you to the XDA page dedicated to the SpeedMod revisions. Right now there is a 13A Test version posted, but the latest stable version is now K12U. If you click where it says 'more info and downloads', it will take you to the developer's(Hardcore) blog, 'Tourist In Paradise'. The revisions are listed there. I would bookmark this page and check back frequently, as Hardcore is constantly updating. However, I'll link you to the latest stable release for ODIN, K12U:
https://docs.google.com/uc?id=0B-3n...WJmNTUtZDVmNThmMmNhZTRm&export=download&hl=en
Thanks for that! I just did this and although it didn't show the ATT boot screen, it shows the Galaxy S I 897 screen after the I 896 though. Thanks again!
Glad to hear you had success. Not so hard after all, eh?
After using this for a day or two:
I can't believe how fast my phone is. I thought it was fast before with (and then without) the oclf. I can barely keep up!
Battery life seems improved.
Screen is perfect. The lowest brightness setting is much better and more comfortable for low light usage.
I lost 1000 points off quadrant, but quadrant doesn't matter.
The only real downside is call quality took a hit. It's a bit static-y and echo-y.
I'll look into this though and see if I can find a solution, but if you have any tips let me know.
Looks like you are a candidate for a modem flash. Let me know if you find something that works, there is a lot of info on swapping modems for SpeedMod. Maybe I'll try one too!
Hey clemmie (or anyone), if I want to install voodoo lagfix - how abouts would I do that if the SpeedMod kernel already comes with / is based on sztupy's Universal Lagfix (enhanced) and if voodoo is a kernel itself (unless I'm wrong about this)?
If you flash the SpeedMod kernel, voodoo lagfix comes integrated with the kernel. It's a master of enabling it from the recovery menu.

So I hate my Samsung Galaxy S i9000 but only because it doesn't work. IF it was working I would love it a lot. The phone is rooted and I am running Vodafone's standard version of Froyo if such a thing even exists (no custom rom).
Now I have read about Odin and different firmwares but I am still VERY lost. I don't even know if any custom firmware would do me any good.
So here are my problems:
My Galaxy S is laggy as hell even tough I have installed lag fix.
GPS doesn't work AT ALL. I have installed pretty much every silly GPS app I could find on forums and in the market. I also entered a bunch of silly numbers yet the GPS is wrong by like 500 metres. Sometimes it gets VERY accurate if I run GPS Aids but google map instantly "fixes" it in just 1 second and screws up badly again >:C
If I take pictures with the front camera they will get displayed once I reboot the phone
and so on. it's completly buggered and I don't know why.
------------
So will a custom rom fix this kind of stuff? will i get working gps with a custom rom or are those gps apps supposed to fix my GPS which they don't at all?
Do custom roms force a loader on me? I like TouchWiz.
Can I still use Gmail and other google apps with a custom rom?
Seriously I am pretty confused and don't know what to do since September 2010 but I never brought up the curage to ask / thought I might figure it out by studying forums but I am still terribly lost.
If your phone is playing up that much I'd think a custom or different stock rom would be the your best bet. I remember when I got my phone it was horrible in terms of stability and lag etc etc, since I've started flashing different roms I haven't looked back, of course you lose your warranty though. I think most of your problems are probably software related, though they could be hardware(gps /camera). To pick a rom your either looking at Froyo or Gingerbread, then do you want a stock(many newer stock Samsung roms are fairly good in stability and performance) or custom(modified stock roms), then you can go picking from there. Read up lots before you flash on what things are(Kernels, modems, clockworkmod, download mode, odin etc) and then if you are confident go for it. Don't hesitate to ask anything
Reading and learning are the key, as stated, my recommendation is to explore the ezbase roms and easy Odin as a great and easy start to rom flashing, and dont be afraid to ask,

thanks a lot for the help.
If I set my phone back to factory reset will it jump back to 2.1 - the OS the phone came with or will it STAY at 2.2?
to be honest I personally believe the rom won't get touched if you do a factory reset so I will be stuck at 2.2. i have called samsung and they said it would jump back to 2.1. now i don't believe a single word samsung says.
IF I can always go back to 2.1 I could try Samsung's 2.3 - see if that does me any good and if that doesn't work I will jump back to 2.1 and root it again and use a custom ROM. I have already rooted it and used a one click solution which exists for 2.1 and 2.2 (i forgot the name of it but it was some orange icon with some arrow in it).

2.2 or whatever the current rom is .
suggest one update to Froyo 2.2.1 its the best . 2.1 is very laggy
no custom rom can fix a broken gps if it is broken
remove lagfix before flashing any rom .
Possible best fix would be to wipe phone via factory reset losing all data
Via Odin install Froyo 2.2.1 with pit 512 and repartition checked .
GPS hardware thread fix may help .

so
1) the samsung dude told sh*t when he said it would jump to the firmware the phone came with (just as i had assumed)
2) froyo 2.2.1 is more stable and better than any build of gingerbread? i thought gingerbread was a great battery saver and overall really nice
3) so with the gps problems i have stated it sounds more like broken hardware instead of software? i could still give the phone back but from everything i have read on the net GPS is just buggered on the galaxy s.
like i have said with GPS aids it will work fine (gps aids will give me a PERFECT location) but once I jump to google maps - google maps will automatically "correct" the positing which will be way off.
4) sorry for that stupid question but i don't really understand "Via Odin install Froyo 2.2.1 with pit 512 and repartition checked". What exactly is "pit 512" and what does "repartition checked" mean?
sorry to ask
Go to ezbase thread and there you will get instructions with screenshots of how to use it, and all the stuff you need to download, and you can then flash either a slim rooted 2.2.1 or 2.3.3.

I have been trying to find answers for a week now and have found a lot of info. The problem is most of the info is contradictory and I'm not really sure which is good and which is not. I currently have an AT&T Samsung Captivate, firmware ver 2.2, kernel ver. 2.6.32.9 build# FROYO.UCKB1. I believe that is the stock At&t froyo build. It is rooted, I do have SGS tools (which I don't really understand what all it can do for me) and Titanium backup (which I've not tried to use yet for fear of breaking my phone). I run 91PandaHome and a bunch of apps I like.
My problem is that the phone sometimes is just really sluggish, certain programs really kill it. For example, I have PlantVsZombies which mostly runs ok, but sometimes slows down and worse 3 out of 5 times I play will not close. I have to power/volume up reboot to get out of the game. Other programs occasionally do this to me, but not as often.
I've been reading up and see that there are lagfixes, and understand that samsung apparently chose a ****ty file system, but I don't understand android well enough to know what's safe. What I want to know is what is as of today the safest, easiest way to fix the lag. I think I am going to be told something that changes the file system to ext4 is what I want, but I really don't understand what will be safe to use for that. I thought I wanted OneClickLagFix, then I found that maybe Voodoo was what I wanted, and now it seems that neither is currently being developed. Reliability, ease of transition and ease of putting it back to stock are important factors for me.
Suggestions, links and general help will be greatly appreciated.
Try going to a custom rom where all of that is done for you. Since you are new to this, I suggest you go look up the rom Serendipity 6.4, it's very easy to install and has it's own thread in the development section.

Just a few quick things:
Titanium backup is a good friend to have on your phone. It won't break it - it will just take snapshots (for lack of a better phrase) of your apps so that you can restore them later if you need to.
Most lagfixes are cooked into kernels, so using lagfix will most likely go hand-in-hand with flashing to a custom rom. Not that you can't lagfix stock, but statistically speaking, lagfix will be done with a new kernel via the Clockworkmod Recovery Menu.
As for general fixing of lagginess... (READ UP FIRST) Flash a custom Rom (READ MORE). Most of the problems you're experiencing (ARE YOU READING UP ON FLASHING?) should be fixed by flashing (DO MORE READING) a custom rom. Do some research on roms and pick one that you think you'll like. (Note - don't post questions asking which one to do, it tends to be a bit of a touchy subject on the forum.) If you're wanting to be cautious, it would be safer to stay with a Froyo-based rom, as they're more tested and there's less danger involved (specifically, you don't have to flash bootloaders, which is the area where you can get a real brick).
Oh, and (shameless self plug) if you need to know what different terminology and items on the forum mean, just click the link in my signature.

Actually, it CAN break your phone if you don't know how to use it. Backing up is safe, but never, ever restore system data with TiBu when changing ROMs and only restore app data you know is safe.
I would recommend staying away from any Gingerbread-based ROMs until you have a better understanding of the phone and the process. Andromeda 3 is a good choice for a Froyo-based ROM and is very easy to flash, but do your research on the process before you attempt it. Almost any custom ROM will have a lagfix in the kernel and performance will be noticeably better than stock. You will likely have to redo your root after installing a new ROM, so read up on that process, too.

I lol'd at the "()" parts
To build on jmtheiss post. For "reliability" look for a KB1 based ROM as this is what your phone is currently running, and is the newest version of firmware written specifically for the AT&T captivate. You won't come across any major issues that make the phone unusable, nor any "annoying" bugs. Then if your feeling more adventurous, and have gotten a solid understanding of the process of flashing ROMs, look to I9000 based 2.2.x ROMs, and lastly 2.3.x based ROMs.
For "ease of transition" start by getting the SGS Kernel Flasher or Heimdall to change the kernel. From there you can get past 3e recovery and you'll be free to make other changes.
For "ease of putting it back to stock" first find out what is your stock. Since this phone technically has 3 different "stock" firmwares. Then get a copy of that firmware (and steps on how to flash it) and keep it on your computer, in a location you'll be able to find easily in case of problems. Depending on how far "to the dark side" you go, will effect just how much of the "stock" files you'll need to keep as backups.
Personally I'd suggest this ROM as it's whats currently on my phone. Many have started off with Cognition and it's still a crowd fav. Both are KB1 based ROMs
Heya guys,
I've been flashing kernels on my phone using mobile odin and sometimes CWM.. I just want to make sure that this is safe? or is there a limit on the safe number of flashes or is there like a deadly combination?? (Example : currently on speedmod then flash hydracore then go to another different kernel then flash another totally different one)
I'm having second thoughts since i think that this might trigger a corruption with the kernel on the phone if the previous kernel was not fully deleted or cleaned or should i Flash stock kernel after a few number of flashes just to make sure the phone is properly cleaned? (i'm also aware of the brickbug so no worries )
I'm just on a stock 4.0.4 and been rooted primarily with notecore v14.1 std then ive been flashing like 30times already since then trying to look for a proper kernel for me..
Sooo, is there anything to watch out? like "dont flash this kernel if you're currently on this other kernel.. etc etc.."
Don't worry I'm always watching out if its stock touchwiz compatible and ICS compatible before i try a new kernel..
And maybe you might also ask, why am I doing this.. I have a problem with my phone that it totally loses signal to the point that the phone says "no service" and then it would reconnect after 1-2mins.. I've proven that its not a network issue since my other phone is sitting pretty on the same desk with no problems on that same cell network.
At first i thought this might be a modem related problem so I flashed multiple different basebands and finally settled with XXLRK since it gave me best data speeds.. So now I'm looking into the possiblity that my problem is kernel related.
Any ideas about this would also be appreciated :highfive:
Personally, I use siyah kernel cleaner first before I jump from one kernel to the other. I just find it's good to run the kernel cleaner first before you jump kernels. And to answer your question one at a time:
1. There is no limit on flashing kernels in your ROM, as long though as you have downloaded the kernel's size correctly. A corrupted or bad download on the kernel itself can cause your phone not to boot anymore. So be wary about it.
2. With regards to your "No service" issue, I don't think the issue is really kernel related. Bear in mind kernels are developed for the primary purpose on performance on CPU/governors and battery.. its one, the other or a combination of both. It's not even touching the radio band itself so I don't think this again is the source of your signal issue. A modem issue perhaps, but not the kernel.
Personally, I'm using LB1 as my modem, it's blazingly fast on the downloads. Had used LRK modem before but I found out that my data speed would randomly connect and disconnect my connection. Flash LB1 modem and it seemed it's all fine and dandy now.
