[Q] General Bootloader and Kernel Questions

Hello all,
I have a few general questions that I would really like some help with:
1.) I understand some bootloaders are not compatible with some ROMs. How do you know which bootloader you are running? How do you change your bootloader, must you use ODIN?
2.) How does the kernel come into all this, are some kernels not compatible with certain ROMs and bootloaders? When you flash a new ROM, does it sometimes come with a new kernel?
The main reason I am curious about this, is because I wish to flash the new Cyanogenmod 7.1 and want to be sure I am successful and do not brick my captivate. I am currently running Serendipity VII Build 2 and want to be as safe as possible when flashing Cyanogenmod 7.1.
Would the safest way be to flash to stock first using the following Odin one click method: http://forum.xda-developers.com/showthread.php?t=731989
Then from there, follow the instructions normally?
All help is greatly appreciated.

There are basically 2 types of bootloaders, Eclair/froyo and Gingerbread bootloaders. GB bootloaders are compatible with preatty much everything (not counting cm7 or MIUI).
Kernels are specific with a type of rom, example Boogs KH3 kernel worked with any rom that was based on KH3 (2.3.4). Some are tweaked specifically for a rom.
On CM7 and MIUI from what I can make out you can run it on either eclair/froyo bootloaders or GB bootloaders but some kernels are specific for bootloaders.

If you are on Serendipity then I am sure you used ODIN to flash i9000 boatloader (BL).
As the above person said there are eclair/froyo BL and GB BL....in GB BL we have captivate BLs and i9000 BLs. earlier GB roms used i9000 BL...then Samsung leaked captivate specific roms...so we have captivate BLs now..
All the one click Odins are used to flash captivate specific BL...
To go to CM7, many people flash it over GB bootloader and have no problem....but the safest way is to odin back to eclair/froyo stock...then go from there.....

Thank you for the help guys, I really appreciate it.
I will be flashing back to stock using the following method:
http://forum.xda-developers.com/showthread.php?t=731989
Then I will simply flash CM&.1 on top of that.
I will report back to let everyone know how it goes.

did your phone come with froyo on it/what is the build number of your phone? its a 4 digit number on a sticker under the battery, for example mine is 1010, meaning oct. 2010. many phones built later than this, and/or came from the factory tend to bootloop from jf6 (the firmware containedin that one click) and have also been known to lose button combos for recovery/download mode which would need both if you were bootlooping and for cm7.
if you have a later build phone it would be better to flash a leaked gingerbread firmware with bootloaders included and then flash a custom kernel with cwm included so that you can then flash cm7 from there.

I purchased my phone at the end of August in 2010. The only 4 digit number I can see reads " 0168", it is the largest number located behind where the battery is held. And yes, I have lost my three button combo for recovery/download mode. It stopped working, and I bet it was because I used that one click method you mentioned.
Do you recommend I flash this one:
http://forum.xda-developers.com/showthread.php?t=1129821
It says Cyanogen Mod users stay away, why is that?
or one from the official list, and if so, which one:
http://forum.xda-developers.com/showthread.php?t=1300843
Also, I am a bit unclear. After I flash one of the stock ROMs with the bootloaders, how can I then flash a kernel with CWM. Can I do it through ODIN?
And just out of curiosity, why can you not use these stock ROMs for everyday use? It seems we always flash other ROMs on top of these?
I know I asked a lot, I would appreciate the help!

You can use the bootloaders in the first link. At the time of that thread's opening, cm7 didn't support GB bootloaders. But, if your not sure how your phone will work with a1 click, I would recommend using the ones linked in my sig.
As for how to flash those roms, there are directions in the first post of their respective for flashing.
You can use a stock ROM everyday, most just prefer not to.

No one said you cannot use stock leaked rom as dialy driver, i actually used KH3 for some times and it was very good.
You should flash the kernel according to the rom you have flashed. For example, For KH3, there is a Boog's KH3 kernel with CWM. For all leaked stock rom, there is one click Odins and compatible kernels with CWM injected.
To go to CM7.1, u shud be on stock (Eclair/Froyo or GB) and should have CWM....

I need help too please. I have a Cappy that was originally on eclair 2.1 rooted. froyo 2.2 Kies mini update and rooted but didn't like it's battery use and slow action. I reflashed an Odin 1 click stock 2.1 back, rooted and then did a Gingerbread 2.3.5 I897UCKJ3_withBL_ Odin 1 click flash and am liking that quite a bit more. The only trouble I am having is rooting 2.3.5. I want to do the fugu kernal swap method with Odin3 zimage-root.tar then flash boog_KJ3_kernel3.tar. I can get into DL mode and hit the start button ok.
Here is the question I have. Where in Odin3 v1.83 do you load the kernal path? PIT,BOOTLOADER, PDA, PHONE or CSC. I can't seem to find a comprehensive Odin3 tutorial on my own and I don't want to flash the kernels to the wrong place. I don't think the first 3 options are right based on their names or info I have found. Can't use CWM till I get rooted so Odin or possibly Hiemdall are my only choices. I have Odin3.
HELP and TYIA

Kernels go in pda

When flashing a single file, unless its a modem or csc file, it will usually go into the pda slot. Modems go into the phone slot. Csc file is a no brainer. I've never saw anything that uses the bootloader slot on a captivate. Pit slot must have a pit file AND repartition must be checked. If you are flashing a kernel to get cwm just to flash a custom ROM, kernel goes into pda slot. If you want to user Odin to flash a modem, it goes into the phone slot. All files flashed in Odin must be a tar or tar.md5 file. Don't change the name of a tar.md5, it can cause a md5 check sum error.
There you go, cliff notes for Odin.
Edit
If I missed something or messed up something, please correct me.

Found Odin3 Answers. Yeah!!!
Studacris,
Thanks for that. Didn't see it before I found the below.
Sorry for the Noob impatience but there is a lot of info that won't show in a search right away. Anyway there is a cool little short video by 4-2ndtwin here on xda with a link here. http://forum.xda-developers.com/showpost.php?p=17788928&postcount=6 The system won't let me post outside links yet.

I Flashed and unbricked and reflashed and restored so many roms now, i have no idea what bootloader I am on. Is there any way for me to tell either through ADB or on the phone directly?

When ur phone boots up and u see the i9000 bootsplash, then u have i9000 Gingerbread bootloaders (we didn't have eclair/froyo i9000 Bls). Also, button combo to get into recovery or download mode is different with the i9000 gb bootloaders.
And if u try and flash an i897 gingerbread rom (and don't see the i9000) but u have a "pixelated" screen, then u have i897 eclair/froyo bootloaders. If ur flash to a gingerbread rom is successful and u see the i897 (att world phone) bootsplash, then u have i897 Gingerbread bootloaders.

[Q] I9000m troubles...

Hello there,
I've been playing with my i9000m for the last 12 hours (...) and I seem to have hit a roadblock. I simply cannot find a kernel that will run on my phone with 2e/ clockworkmod recovery AT ALL and it's driving me a bit nuts. I'd love for someone to point me in the right direction, preferably to an Odin flashable (that's pretty much all I'm comfortable with) 2e/ clockworkmod recovery kernel that will actually get past the boot screen on an i9000m. Any help would be appreciated. Thanks, all.
Oh, and if I should be using something other than Odin, please inform me. And if my thinking is all backwards, smack me and gimme some splainin, if you'd kindly. Thanks again.

what version of android / rom are you using? It will make a difference.
I'm using the stock gingerbread 2.3.3 UGKG3 rom designed for the i9000m. AFAIK, there is no custom kernel that will work with this rom - only the rooted stock kernel with no CWM.
If you want to use a custom kernel that has CWM features, I think you need to install either a stock i9000 rom like XXJVT, or you have to go with a custom rom entirely.

what exactly are you trying to do? If you want the latest stock rom with root. Flash JVT pda, with KG3 modem and CSC and 512 pit, in odin then flash latest semaphore or chainfire kernal to root. Put file in pda and flash in odin. There are alot of good tutorial on here.
Firmwares: http://forum.xda-developers.com/showthread.php?t=1102881
Root Kernal: http://forum.xda-developers.com/showthread.php?t=1112908

I've just got UGJL2 on it atm, since that's the only thing i can get to actually run. I'll give XXJVT a shot. But ultimately all I want to be able to do is try some of the custom roms (cyanogen, miui, apply some fancy lock screens through update.zip) through the use of ROM manager... which I do need CWM for. I do like the stock gingerbread rom, I just want to customize it a bit.

cyanogen and miui are completely seperate roms, they are not based on samsung what so ever. You should probably just stick to stock jvt for now. (until you get your feet wet.) There are alot of great custom roms you can run on stock jvt. You just need to get that up and running first. Follow the instructions in the links I gave you. I live in Canada too, and run JVT pda on my phone, with KG3 modem and csc, works perfect, install semaphore kernal after, its the file linked Semaphore_Kernal_JVT_1.8.2.tar. Once your rolling you can install zips through cwm. Just remember to keep your baseband version, your modem KG3 or you will notice your cell coverage sucks. With KG3 its full bars. The firmware in the first link I gave you contains bootloaders so you can flash straight from there. Remember to use the 512 pit file. Since this is the first time your flashing gingerbread.

Alrighty, I see how it all peices together now. I've got the UGKG3 modem and CSC installed alongside the xxjvt PDA with Semaphore JVT over it. Runs really nicely too, Thanks for all the help guys. I'll play with this for a while, hopefully it'll continue to run nicely I'll go gander around at the other roms now that I actually know what i'm looking at! I like this one though, thanks for the reccomendation. And I do indeed have my CWM installed, so i can go gallavanting now
Thanks guys!

Happy rom hunting

Which "JVT" ROM did you guys install?
XFJVA/XXJVT/OXFJV1/Sbl or XXJVT/XXJVT/OXAJVT/Sbl (or does it matter between these two?)

Samsung Galaxy S i9000m bricked after installing wrong Clockwork Mod!

Alright, so this is my first time posting as I can usually find my questions in another thread... Haven't been able to find this one however.
So I rooted my phone earlier today and have been trying to get the Clockwork Recover Mod on it. I followed a tutorial and made a bad mistake... It seems I downloaded a CF-root made for the i9000 as opposed to the i9000m. Now when my phone tries to boot, it cycles between displaying the start-up screen for each, but it never boots. I can still access download mode, which I understand means I can still change it... But what am I supposed to do?
Further info: Running Android 2.3.3 on Bell.
Thanks!!!

Ditch the i9000m stock rom (which is UGKG3 2.3.3, the one you're probably using) and flash JVT (2.3.5) stock rom, then flash CF-root for JVT. The Bell i9000m will run on the International i9000 firmware and this should get you out of the bootloop.

I hate to sound super uninformed, but how should I go about doing that? Where do I get the stock rom for 2.3.5?
Thanks so much for the help though, I might just need a few extra steps to help get me there...

Follow the instructions on here. Use the JVT 2.3.5 PDA, KG3 modem, and csc...its the canadian one. And you might as well repartion with 512 pit. All this can be downloaded on the link above. After you do all that you will have the latest gingerbread firmware. Now you can root with a JVT kernal like semaphore or CF root. There are also a bunch of custom roms you can use on JVT not much if anything for I9000m . The only thing you need from I9000M is the modem and csc....otherwise your cell coverage will suck. I assume you already have odin, if not its available on the above link aswell.

good advice. One other idea, since CF root tripped you up the first time, reduce your anxiety level and root using Hardcore's kernel for JVT or something similar -- one that is robust and also has good step by step instructions.

Question on which files to pull from the site for kernels, modem and csc files...

I have a Bell Samsung Galaxy S I9000M also and am trying to install the Clockworkmod 2.5 hardcore kernel also and got into this boot loop...fortunately, I had the kg3root.tar with the kernel in it to re-flash and get operational again.
For us newbies, perhaps you could direct us to the specific set of files that we need to flash (with links to them) and the instructions to apply them.
I think to have a rooted gingerbread with clockworkmod recovery functional...at this point the ICS update should be able to be done using the instructions on the web. (hopefully)
thx.

Error while flashing Rom with CWM

hi.
i have an Australian N7000B Note, and it is currently rooted on the latest available android in the country for the phone (2.3.6)
i have superuser and CWM installed.
i can boot into CWM and navigate with no worries, but whenever i try to install any custom rom, regardless what rom it is, i get the same error.
i really want to get off this crappy rom that Telstra provides with the phone, so any help is greatly appreciated.
many thanks
pic attatched of error.

Use ODIN to flash a stock ICS or GB ROM and then re-root and add cwm and try again
the issue you face is because your version is the GT-N7000B and the build.prop is for the GT-N7000 so its failing because it believes the ROM is for a different device.
if the product codes do not match up in the build.prop it will fail - this applies to all devices and all ROMs.
you could also open the .zip and find the build.prop and change all of them, But its a pain in the ass !

Because these are for the N7000 if i flash a stock ICS rom on my N7000B what will happen?

http://www.sammobile.com/firmware/?page=8
Put your details in there and it will find you a stock ROM. Ive seen threads where N7000B users have flashed N7000 ROMs without any issues.
EDIT: You CAN use any GT-N7000 firmware !

Awesome! I am downloading the Gingerbread Australian Rom as we speak for the N7000. if i flash it with odin, root it, and then install CWM would it work with installing custom roms such as paranoid android etc?

Yes because the Stock firmware will remove the 'B' and you will have no more install errors
Be sure to follow the instructions to the letter !! and make a nandroid before commencing.

Well, i have a nandroid backup of the current firmware, i made it just after i rooted it.
so, i will flash it with Odin on PC correct? does it require i wipe everything off the phone?
sorry for the questions i am a noob lol

you can wipe before or after it makes no difference so long as your on GB.
Dont ever wipe on ICS unless your on a safe kernel.
But do do a wipe as it will start you off on a fresh clean install

Going from stock 2.3.4 to ICS

Hi people of i9000
I will be receiving a second hand Galaxy S one of these days. Now check my postcount, and the fact that I had more phones than some people change underwear in a month, but I don't want to mess up this phone.
According to the owner the phone has --> 16GB, Android 2.3.4 with I9000XXJVQ
Knowing my history I will get the phone, boot it ... and flash it after 2 minutes.
I have 4.04 on my S2 and I like it so I want to move to a rom with that version.
Now I've checked the stickies but it seems (maybe because it is right in front of my nose) that I can't find any thread that deals with this directly.
I will need odin for sure but then it gets a bit blury for me.
Anyone willing to point something out for me?

It should be a simple progressive upgrade
1) update it to 2.3.6 Firmware, http://forum.xda-developers.com/showthread.php?t=1102881 according to your region First
2) Add a Kernel with CWM, like a semaphore kernel http://forum.xda-developers.com/showthread.php?t=1112908
3) USE CWM recovery to flash ICS 4.04 ROM of your choice from SD card
I doubt you need a guide on basic flashing procedures
