i have captivate with at&t bootloader,if i flash a custom rom which is built in i9000 bootloader is it make any difference ?. after flashing i9000 bootloader can i use galaxy s custom rom on my captivate?.
Custom roms don't usually have bootloaders built in. That us something that"stock" roms do. ROM developers usually remove them, providing a link in the op of their thread for those that need them.

The i897 and i9000 gingerbread boot loaders should work for any non-CM7 based ROM in the development section. The only issue you may have with an unmatched boot loader to the ROM is the stock music player skipping when the phone is locked.

From my understanding att gb roms doesn't work on i9000 gb bl. Can someone confirm this? Also cm7 roms works on GB bootladers (both att and i9000) for most people.

i897 GB bootloaders and I9000 should work each way. As mentioned before the music player issue is there. That being said Some devs feel that if you are running I897 BL on a I9000 port and its acting funky could because of the BL. Same applies if you are on a I897 rom with i9000 bl's. As to my knowledge CM7 and MIUI work on both eclair bl or GB bl, I do believe there might be kernels for specific bl? Not sure anymore, stopped following a while back.
Don't know about cm7, but i9000 loaders on MIUI can cause a few minor acts of weirdness, the biggest being not able to see your external sd card. Also, in my experience you haves to be on a Samsung based ROM because if the file system to change bootloaders. I've tried ato c change while still on MIUI and I got nothing but boot loops. As for kernels, bothGlitch and Platypus kernels will work on the I897 GB bootloaders now.

I am new to Galaxy S but have had experience with roms, kernels and radios from a G1.
I started with Samsung 2.2 firmware and rooted it using Cyanogenmod wiki page and flashed the latest MIUI. I know kernels change speed and include Voodoo colours and sound for Galaxy S. I also now radios can change signal and gps accuracy.
1)Are modems the same as radios and if so where do I find a list of them?
2)What is the best bootloader and why does the Gingerbread one not have sd cards work? Also what else doesn't work?
3)How can I check which radio I have and if I flash any bootloaders how do I check that?
Radio, Modem and Baseband are all the same thing. You can check which one you have by going to Settings >About Phone and checking the Baseband Version.
A new modem is easy to flash as a zip file from Recovery and you can find lots of them by searching in the Dev forum, however make sure you flash a modem that is for CM7 since you have Miui installed. For guidence you can search for Modem in the Miui or CM7 thread in the Dev forum.
As for bootloader, there is no way to check which you have, but as you installed Miui directly over 2.2 you should have the froyo bootloaders. CM7 and Miui were designed for froyo bootloaders. Some people say that GB bootloaders have better battery life but if you have GB bootloaders with CM7 you can't access you external SD card and other things may not work properly. I would suggest staying with froyo loaders for now and seeing how it goes.

I have read this:

but I don't know if it still JPP is the best radio as this was back in December. For people in the UK what would be the best overall radio?
can anyone answer me which is the best CM7 modem for ORANGE ROMANIA? tks
Try jvp or jpy, I'm on orange uk, insanity cm and they both work fine for me don't forget you need cm7 modem, there are 2 threads in dev for this

About bootloaders
I have a SGS GT-I9000, and following
directions from ROM kitchen, I installed a Froyo 2.2.1 version.
It's I9000XXJPY with 2.6.32.9 [email protected] #22 kernel
and it says Rom kitchen v11.1-ZSJPK.
I wanted to install a Gingerbread version from ROM kitchen as well, but it says I have to make sure I have at least JVH bootloaders. Ummm, do I ? And what to do so i could install a gingerbread to my SGS ?
I installed a 2.2.1 froyo also from ROM kitchen I9000XXJVO with 2.6.32.9 [email protected] #22, build number XWJSD, hoping i'll install newer bootloaders with it.
But, i had problems with messaging so i'm gonna have to revert to previous one.
Do i have proper bootloaders or not and what could happen if i tried to install Gingerbread and don't have proper bootloaders.
Thanks in advance
Can someone please tell me if I can just download a new rom such as serendipidy 7 or will i have to install new boot loaders first or ?
What is the best procedure for me to use?
TIA, Jeff
If your have never flashed a 2.3 rom (except cm7/miui). You will have flash GB bootloaders, the rom developer should have instructions on how to do that.
Am I correct to think based on your reply "(except cm7/miui)" that these don't require bootloaders?
While cm7 and miui are gb, they don't use gb bootleggers. Therefore, you will still need gb loaders.
im very confused about the captivates organization of roms and what is and is not jvb and jvh.. i own a fascinate. and the only (only letter) acronym used with the fascinate are our "MTD" roms which is the file system used for our aosp roms..
what roms are jvb, jvh? what is your most current source? gingerbread or froyo? what is your most current ota?
JVB, JVH etc are leaked builds for international galaxy S I9000 which have been ported to work with captivate. If you go by this JVR which is 2.3.4 is latest.
But all these are I9000 sources modded to work on captivate. If you are looking at stock captivate build it is KF1 which is GB 2.3.3. KF1 is also a leaked build
Ok.. I have decided to go straight to miui. On the fascinate I would just odin all in 1 stock. Odin a recovery. Flash rom with kernel. It seems like all the guides I find want me to root.. Why would I root if I'm leaving the rom behind end going straight to a rooted rom? .. Is there a guide to flashing miui for captivate I'm not seeing? On fassinate you must flash cm7 first. I'm thinking I would do the same here right?

In answer to your question, here is the guide.
You'll want to be rooted for one simple reason - usually rooting allows you to install the ClockworkMod Recovery Menu (CWM) that will make installing Roms on the Captivate a whole lot easier.
Judging from the guide, you don't need to flash CM7 first. Just make sure you're running the original Froyo/Eclair bootloaders (if you haven't flashed gingerbread, you should have them), and that holding Vol+/Vol-/Power gets you to the recovery menu and that holding Vol+/Vol- and inserting your USB cable gets you to download mode.
Other than that, MIUI away.
Is your version of miui a mtd based rom?

I honestly couldn't tell you. I haven't used MIUI, so I don't have any experience to say. The MIUI info page is a little sparse, but a quick search in the thread does mention MTD a few times, so it's possible.
Cappy miui is MTD based. Gingerbread bootloaders do work but the stock miui/cm7 kernel doesnt ssupport them yet so you'll need to flash a kernel that does support the gb bootloaders such as TalonMTD

I ran miui on gb loaders with no problem. And I used the platypus/NEO 10, 12, & 16 kernels. Talonmtd actually kept causing my phone to freeze up.

Been running Cog4 for a while now, but figured it's time I upgraded to GB. Ling story short:
What's the easiest way to upgrade my bootloader? I noticed it's a prerequisite for a few GB ROMs I was looking at.
And should everything bug out on me, is there a way to return to a 2.2 based ROM?
Appreciated!
There is a Bootloader package in dev section. GB bootloaders are backwards compatible with 2.1 and 2.2 roms. Also work with AOSP (MIUI, CM7). You can also just flash leakes GB roms that contain bootloaders. All can be done with ODIN and Heimdall.

+1 the easiest way is to flash a one click package with GB bootloaders
+1 again - I was on Cog, upgraded to Gingerbread, and am now on Serenity ROM,. Quite happy thus far.
hello,
i was on gingerbread rom. than i flash back to froyo using heimdall oneclick uckb2 with out checking the option of bootloader.
Now i successfully flashed to froyo but i have no idea which bootloader i have now ? whether i m on froyo bootloader or gingerbread bootloader ???
I personally think, i m on gingerbread bootloader because i not checked the option of flashing bootloader when going from gingerbread to froyo. plus i hv changed download mode screen i.e the one which i had on gingerbread.
i wana install cm7. any help ?????

I would guess you are on GB bootloaders, but it doesn't matter which ones you are on if you're going to CM7. I wouldn't worry about it until you flash to something else. At that point you can either just reflash a full package with bootloaders to be sure or try flashing without them and see what happens. You should get a pixelated screen at boot on GB if your bootloaders are Froyo.

Yes, as long as you flashed a GB bootloader to get on GB then that's what you have. Just go ahead and flash CM7
Sent from my (CM9) ICS i897 Captivate
As mentioned earlier, if you want to know, just flash a gb ROM. You'll know if you have the wrong bootloaders as soon as it boots. If you think you may have the I9000 bootloaders, power the phone off and try volume up and power at the same time.
I read some where that froyo bootloader is neccessary for flashing cm7. So if I have ginger bootloader. Will it make problem? ?

Not anymore. It used to be froyo only, but now it works with either. However I9000 GB bootloaders may not play nice.
Ohhhh that's nice to know. So it means I can flash cm7 even if I have gb bootloader? ??
Well, yeah.
Whats the difference between cm7 and cm7 nightly ?
For all practical purposes, nothing. CM7 is compiled nightly (well, sort of, the build bot is currently broken) with updates, new features, bug fixes, etc. Every so often when they get a version stable enough for everyone's liking, they make it an official build. The reason I say there's not really any difference is that the current nightlies are at least as stable if not more stable than the current official release.
181 was the last official nightly released if I remember correctly, but you can find other people who are compiling the updates themselves. The one many of us are using can be found here: http://forum.xda-developers.com/showthread.php?t=1347273

Just download the nightly to your sd card and install it from recovery. And no clue, I have never had any lag with adw launcher. You can try others to see if it helps

Cm7 is going to have worse battery life than touch wiz roms. Its a known issue with aosp roms. They don't contain the closed source hardware drivers. That the tw roms have.
