[Q] confusion about JVB/JVH and other only letter listings

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.

But could you access your external sd card on GB bootloaders?

[Q] Rooting and Installing ROM on GT I9000

Hi,
I finally got a Samsung Galaxy S after finding a great a deal on it. I'm aware that there are several ways on how to root this device. However, due to that I don't know which to use.
Currently I'm running on 2.2.1 Froyo XXJPY with Kernel Version of [email protected] #1.
I'm not totally clueless about rooting as I've done it already on my HTC Wildfire.
Could someone please advise me which is the most up-to-date and safest method of rooting? Link would be greatly appreciated.
Also, I'm a bit confused about installing ROMs. I used to use CWM on my HTC Wildfire which was incredebly easy to do. Would it be the same on my Galaxy S?
I'm planning to test out MIUI, DarkysROM and such ROMs. Would these ROMs have the LAGFIX feature integrated in them as well?
I apologise if a thread like this has already been posted a thousand times but I just can't come up with a definite answer.
Thanks in advance.

I have a galaxy s Vibrant the I9000M and I rooted and unlocked mine today using SuperOneCick and then The Galaxy s unlock by helroz on the app market took a grand total of 6 minutes

Thank you! Now, that's one down.
Now just want to know about flashing ROMs e.g. MIUI, DarkyROM and such.
Do I need to root my SGS first to be able to flash custom ROMs?
I also noticed that you would also have to flash firwares and kernels. Do I need to this before flashing custom ROMs?
Thanks in advance.

In order to flash a custom rom you need to have clockworkmod (CWM) recovery.
and from that its easy
As for the newer rom's here, they are all 2.3.x, so in order to get from 2.2.1 JPY, you will need to flash a stock rom 2.3.x with bootloaders via Odin.
use this link to read about odin and flashing with it. its a great guide
http://forum.xda-developers.com/showthread.php?t=723596
to find stock rom's - they are in the general section. and custom rom's in the dev section.
read a little and after that have fun!!
And keep in mind every rom has its little guide, read those before you flash any.

Hi,
Many thanks for replying. Can I follow the video below made by a fellow XDA member direct from 2.2.1 to 2.3.4 via Odin?
http://www.youtube.com/watch?v=6lO3Y86N2p0&feature=BFa&list=FLqhM0qK4aVsLmWAA_YYhBCA&lf=mh_lolz
So I will Download stock JVQ from Samfirmware > Download Odin > Flash a stock 2.3.4 JVQ > Install chosen Kernel with CWM > Flash chosen ROM using CWM.
When would I need root then?
Is that right?
This reminds me when I had my Samsung Tocco. Pretty much same procedures.

That is right... basically when you flash a kernel with CWM you get root access. it's one of the features of a custom kernel. some of them activate it on there own and in some you need to activate it your self from the recovery (very simple).
And all the custom rom's come with root access, so in following the steps you wrote, you will get the root access with the custom kernel, and again in the custom rom.

Thanks for everyone's help. I'm now running Armetris 3.6.1 with Semaphore Kernel.
Just a question though, with my phone rooted, lagfix enabled, flashed with custom ROM and such, can I just simply go back to stock ROM? e.g. JVQ/JVR using Odin without any problems?

It is suggested to disable lagfix before changing rom's and kernel's
I know some how would say it is not a must when you use odin, but i always disable it before doing changes. I like to keep it safe.

sorry for this nooob question....
new to the samsung gt i9000, do i need to create a gold card before i do anything else????
sorry to be a bit thick but im used to htc

Hi,
Thanks for the reply. I'm currently running on Semaphore Kernel but I can't find any Lag Fix option on my phone? There isn't any on CWM Recovery as well.
I thought when you use EXT4 and convert it, Lag Fix would show up but I found nothing, so I just converted back to RFS.
So, I'm fine to directly go back to 2.3.4 JVQ even even I have a custom Kernel and custom ROM?
Thanks in advance!

If you used the EXT4 app and converted to RFS then you have disabled the lagfix.
The lagfix changes the filesystem from RFS to EXT4. so when you converted to RFS yoh disabled it.
So,yes you are good to go.

Gold card?? what??

Also, If I were to flash a JVS Based ROM do I need to be on stock JVS and a JVS Kernel to flash it?
Once on I'm on JVS custom ROM can I just go back again to JVQ stock (Older firmware) without problems?
Really appreciate all your help Bork84!

Basically using odin you can change to JVS and JVQ no problem.
As far as custom rom, from what I know it does not matter on which 2.3.x you are, thay all have the same bootloders. so technically you dont need to be on stock JVS to flash a JVS custom rom.
but I am not an expert on that.
from my experience, i flashed to a JVR (2.3.4) custom rom via CWM from a 2.3.3 stock rom, and didn't had any problems.
So i cant give you a 100% answer

[Q] Most efficient/Cleanest method of getting GB Bootloaders?

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.

Question about Rogers KK4

Hey guys, I know it may seem a little tedious or pointless, but I want to put the stock kk4 ROM on my Rogers captivate, however I don't want to see AT&T when I boot up. People say that the KK4 ROMs are the most stable, better than Froyo, which I was so tempted to go back to due to lame battery life and so many force closes, email problems, etc. So 1) Is it possible to see this Rogers, or is there a stock KK4 (GB) 2.3.5 I assume, ROM? Is it a good idea to keep my KK4 or should I go back to some 2.2 stuff? Thanks for your time guys really appreciate the input!

To do that you need to change your Param.lfs and get a kernel with a different bootscreen. I haven't used corn lately to know if THAT kernel has a different screen, but I know its the only kernel build from source to date. You can look up mobiletechvideos.com for how to change param.lfs. GL

Or he could flash Rogers GB Bootloaders and flash the Corn Kernel.

Edit: If you're looking for the Rogers GB Bootloaders, here it is http://www.mediafire.com/?h1iejva6x4ikdnu.
It comes with Heimdall, use it to flash the GB Bootloaders.

Or that. Just offering ideas. More than 1 way tackle a problem.

Try i9000 GB bootloader if u want to avoid the at&t bootscreen. You should try Apex 12.3 it's very great rom

Sorry for reviving an older thread, I was in the process of moving. Part of the question was whether or not I should stick to a kk4 "i897" romn my rogers captivate or go to ICS or to 2.2. Again thanks I really appreciate it.

Nothing to do with this thread but Usually OP for ICS roms have their own instructions. If you are on KK4 with Korn Corn just flash from there (might need to flash twice depending on rom). Like I said follow OP instructions but you should be good from kk4.

KoRn is a band, I think you meant Corn

rom suggest cognition w camera

Cognition 5 rom seems like the best but there are people with camera and other issues,
I just rooted and unlocked my captivate, here are specifics as is: firmware 2.1-update1 baseband I897UCJH7 kernel 2.6.29 [email protected] #2 build GINGERBREAD.VUVKJ6 build ECLAIR.UCJH7
I don't want to sacrifice functionality for a phone that looks good or is too modern for the captivate to handle, I want a rom where I will have no issues whatsoever with things like mms, camera, ics, wifi / 3g sip w & w/o bluetooth (w sipdroid), tethering, installing to sd, that has a promise of performing well for a good while and ideally for the rest of the life of the phone without having to possibly upgrade ever again.
I didn't find a barebones rom for this as the vibrant does, so what other roms you think will be most performant and stable?

Try the latest official release, Stock Gingerbread 2.3.5 i897ucKK4 first. To get Root on the KK4 use this... [Utility]KK4 Easy Root. And then if u want to venture out to Dev Roms from there use TRusselo's Guide.

thanks for the advise. btw why should I go with or without bootloaders on that firmware as I don't know what the difference would be.

U have to have the gb bootloaders in order to run any gb rom. Eclair/ Froyo bootloaders are different from Gingerbread Bootloaders.
