[HOW TO] Galaxy S I9000 ROMs (Eclair & Froyo) on Captivate - Updated

The stock I9000 fixes many issues the Captivate ROM such as 'stalling' and has none of the AT&T installed bloatware. It's very fast by comparison, and everything is working great except for the FM Radio app and the Wireless tethering app. The stock I9000 firmware also allows sideloading applications so there is no need to edit the settings.db. Some people have reported issues with bluetooth and voice call quality. I haven't personally experienced any problems but be aware that some minor issues have been reported.
If you have problems getting into Download Mode try this method:
1. Take out your sim card, sd card, battery and open Odin3.
2. Put the battery in.
3. Plug in USB. (the phone will power on to that screen)
4. Hold down both Volume keys, and then push power. Hold it and dont let go.
5. Wait for it to go black.
6. When it goes black the 2nd time release power and keep holding the Vol Down and Vol Up.
You will need to be running the stock Captivate ROM. If you need to return to stock or fail to flash a ROM use the one-click application:http://forum.xda-developers.com/showthread.php?t=731989
Eclair I9000 ROM
You'll need the following:
Odin, the zipped I9000 firmware and the 512 pit file from here: http://samfirmware.webs.com/WEBPROTECT-i9000.htm
Stock Captivate kernel from here: http://koush.tandtgaming.com//test/kernel-captivate-stock.tar.md5
New Method (Requires adb)
1) Remove SIM and MicroSD
2) Open Odin, load the I9000 PDA file (CODE_I9000xxxxx.tar.md5).
3) Check auto reboot and leave repartition unchecked.
4) Boot the phone into download mode (adb reboot download).
5) Flash.
6) Once the flash is complete the phone will be stuck in recovery.
7) Reopen Odin and load the stock Captivate kernel (kernel-captivate-stock.tar.md5.tar) in the PDA box and the 512 pit file.
8) From recovery boot the phone in download mode (adb reboot download).
9) Ensure auto reboot is checked and repartition is not checked.
10) Flash with Odin, the phone will boot.
11) Shut the phone down, replace SIM and microSD and reboot phone.
Older Method
1) Remove SIM and MicroSD
2) Open Odin, load the I9000 PDA file (CODE_I9000xxxxx.tar.md5) and the I9000 CSC file (CSC_I9000xxxxx.tar.md5).
3) Uncheck auto reboot and leave repartition unchecked.
4) Boot the phone into download mode (adb reboot download or boot phone while holding Volume Down + Power Be sure to HOLD Volume Down before holding Power) .
5) Flash.
6) Once the flash is complete (Odin will say RESET!) remove the battery, disconnect the USB cable and close Odin.
7) Reopen Odin and load the stock Captivate kernel (kernel-captivate-stock.tar.md5.tar) in the PDA box and the 512 pit file.
8) Ensure auto reboot IS checked and repartition is NOT checked.
9) Boot the phone into download mode (Volume Down + Power) then plug in the USB cable. If you don't put the phone in download mode before it boots you'll have to start from step 2.
10) Flash with Odin, the phone will boot.
11) Shut the phone down, replace SIM and microSD and reboot phone.
If you want root access use this (I9000) update.zip: http://www.multiupload.com/JHIFK9K80P
If you need a custom recovery use ROM Manager in the Market to install Clockwork MOD for I9000.
Froyo I9000 ROM (Early Release)
Please note that as there is no Froyo Captivate kernel the stock I9000 Froyo kernel will have to be used. Expect the following bugs:
Home Button functions as Back button.
Screen is rotated 90°. (Not a huge issue as there is a Notification button to disable rotate.)
Speaker/Headphone logic seems reversed, will only play audio through speaker when headphones are plugged in.
Proximity Sensor is not functioning.
You'll need the following:
Odin, zipped XXJP3 I9000 firmware and the 512 pit file from here: http://samfirmware.webs.com/WEBPROTECT-i9000.htm
1) Remove SIM and MicroSD
2) Open Odin, load the Froyo PDA file (I9000XXJP3-REV03-PDA-mid-CL470734.tar) and the Froyo CSC file (GT-I9000-CSC-MULTI-OXAJP3.tar).
3) Leave auto reboot checked and repartition unchecked.
4) Boot the phone into download mode (adb reboot download or boot phone while holding Volume Down + Power Be sure to HOLD Volume Down before holding Power) .
5) Flash.
That's it, you can't flash the Captivate kernel since all available kernels are Eclair.
Please post or message me with any issues you have.
I'll be updating the post with advantages/disadvantages and bugs for both ROMs so please post your experiences.

Have a link to the I9000 files and a walkthrough for this?

http://samsung-firmware.webs.com/
and the Captivate kernel from here:
http://koush.tandtgaming.com//test/kernel-captivate-stock.tar.md5
Use Odin to flash the I9000 PDA and CSC. After that completes use Odin to flash the Captivate stock kernel. If you want root you'll need to use the I9000 root update.zip. Once the Market is working you can install the Clockwork Recovery for the I9000.

I've been running the latest I9000 firmware (XWJM2) on my Captivate by flashing the I9000 PDA and CSC, then the Captivate kernel. It's very fast, everything is working great except all my market downloads fail and Google Talk doesn't open.
Any ideas? I don't want to have to go back to the slow, bloated stock Captivate ROM.

You tried Market Enabler yet? Pretty sure the .apk is linked on XDA somewhere.
Oh, and are you SIM locked still?

What is you re market doing exactly? Don't care much fort the google talk. How about hardware function? Have you apply the mimocan kernel? Sorry about all the questions.

How about wireless tethering and FM Radio? Do these work with the euro firmware ?

Reaver117,
Awesome Layout
thanks

@sl8125
All the hardware seems to function fine, I haven't applied the stall fix kernel because it's based off the I9000 source and the phone seems fast enough without it. As for the market, all market downloads fail with 'download was unsuccessful'.
@clubtech
The FM Radio app opens and seems to function, but if you try to scan it states 'Unable to turn radio on'. I haven't been able to test wireless tethering because I can't use my data plan until it's unlocked.
@larry996
I can make a detailed walkthrough but without a functioning market the phone is not very useful.

Is it really necessary to re-flash the captivate kernel? What happens if you don't?
Did flashing the PDA and CSC change the kernel?
Did you backup first then restore? If so which program did you use?
I have been following 2 threads over in the i9000 forum but was waiting for someone to try it on the captivate first. I noticed that some of them had to wait 12hrs or more for paid apps in the market to show up for them. Your market download error may be similar?
Did you record your APN information and add it back after flashing? I have seen that some people over in the i9000 forums had MMS and messaging issues.
If market start to work properly and there are more feedback I may give it a try.
Right now I am on stock:
PDA: I897UCJF6
PHONE: I897UCJF6
CSC: I897ATTJF6
To those wanting a guide. There is a PDF in the link that was posted.
h t t p: / / samsung-firmware.webs. com/Flash%20guide%20english.pdf
I hope you don't mind the all the questions, but when you post info like this its bound to happen.

If you don't flash the Captivate kernel then the volume buttons are reversed and the display is rotated 90°. I used the clockworkmod recovery to perform a nandroid backup. Flashing the PDA file replaces all system files including the kernel. I'm not having a problem with protected apps, nothing successfully downloads from the market. APN Backup will let you backup your APN info.

Had that with my stock rom happening where I get "unsuccessful download". After reading some forums someone suggested to clear the cache on the download manager and that did the trick for me.
Settings - Manage Apps (filter all) - Download Manager - clear cache.
Hope this helps.

This worked on the browser for me once when I was getting failed downloads. I didn't think about this.
REAVER117 please let us know if this sort your issue.

Solved it. When you apply the I9000 PDA and CSC files DO NOT check Re-Partition.
I'll post a step-by-step later tonight if anybody wants it. Running the I9000 firmware cuts out all the AT&T bloatware and adds some useful apps AT&T cut. Not to mention its MUCH faster and lets you sideload apps by default.

I would like to see a step by step so I can give this a try. Thanks for offering to do it.

Dude, be sure to mention that you're not connecting to any cell network because your phone is SIM locked, and as such can't assure phone functionality with this Frankenbuild.

No youre internal sd card does not get wiped.

I just tried this.
Flashed PDA and CSC with the latest firmware, did not partition. then flashed the Captivate Kernel.
The phone is booting but it can not see a sim card is inserted and i can't get signal.

Safe way to load Froyo on i9000m Bell Mobility Galaxy's

Okay, so after corrupting my SD card over 12 times and replacing my phone twice I think I have found the answer.
I strongly believe that the reason we get faced with the SD corruption (The ones where it is fixable by a software reset at the service center) on our i9000m's is because we repart while flashing.
The 512,513,903 pit files might be okay on international models, but I suspect that the Canadian version uses some other partition structure.
So to keep it short here is a successful method to install froyo on the i9000m. I have flashed to froyo using this method and have been using it for over 20 days now without issues.
Make sure you get a brand new phone before flashing. If you have reparted using odin this might be useless.
Installation Steps:
1. Make sure your phone is rooted (You can root via OCLF in the market)
2. Download Rom manager and install Clockworkmod recovery (Instructions can be found here - http://forum.xda-developers.com/showthread.php?t=734166&highlight=clockwork)
3. Install Doc's froyo rom from here ( http://forum.xda-developers.com/showthread.php?t=817703)
Once flashed it should work fine. When the phone starts make sure you first see the I9000M screen and then it switches to the I9000 screen and then the Galaxy and then into Froyo.
I have not tried just flashing froyo using ODIN without re-parting (Maintaining factory partitions). In theory it should work, if anyone tries it let us know.
P.S. I use Doc's rom as it allows to flash via clockwork. I am not endorsing this in any way.

I have personally flashed dozens of things through Odin with 512 and 803 pit, as well as tons of things through zip's like Doc's, with absolutely no problems on my Bell I9000M 16GB.
**Knocks on wood**

Do you lose your 850 Band doing it by this method. Please check by Activating WiFi while in your service menu (*#*#0011#*#*). You will see when you switch over from WiFi to 3G you Band should drop down to 850 from 1900.

Can you give more information on what happened.
Original ROM?
Froyo Version tried to flash to?
Which SGS ei (gt-i9000m or gt-i9000)?

I've re-partitioned in ODIN by flashing back to JH2 (2.1), then use Doc's ROM to 2.2. What should I do to enable 850Mhz? I already added WCDMA850 in *#2263#

I am an Indian & have an Asian 16GB SGS. Every time & have this urge to FLASH, I just pick the pit file, nothing else, check re-partition, let the phone reboot, remove battery, re-insert, go back to download & re flash.

Me n 2 friends bought it together from same bell store 3 months ago.
Friend 1 :
On his 2nd sgs.
Got it replaced because internal sd got corrupted.
He was on jpk w/ repartition done
Friend 2 :
Still on his original sgs.
Stock + voodoo (aka never used odin)
Me:
On my 3rd sgs (if u count replacing the pcb as a new phone)
First one was stock + voodoo (stock was flashed using repartition through odin)
Second one was jpk w/ repartition
Third one im running with stock + voodoo (aka following friend #2's approach)
Hope tht helps :\

Most of the time what I do is use Odin 1.3 Use an 803 PIT re-partition not checked at the same time select the PDA Phone and CSC since your 900MHz you should not have a problem using the GT-i9000-CSC-Multi-XXXXX.tar.md5 for CSC and the MODEM_i9000XXJPK.tar.md5 for Phone and your PDA will be JPM/JP6 or whatever rom you wish to install

Funny thing is I'm on 3rd SGS now too my first one I went crazy on Flashing everything as I had no problems with anything I did to it until JPM/JP6 I bought another SGS while I sent in the other one as a replacement for mine and as a gift for my wife after I get my SGS back from bell. The one I got for my wife died within 6 hours of flashing ROM's I use to have the 850MHz band on my original SGS throughout the whole flashing process but I couldn't repeat it with my wife's SGS. Now since I've buggered hers once already I'm now scared to do anything with this one. Although I still have the DOA warranty on it. I'm I crazy??? Probably more confused as I spent a lot of time reading on these forums and don't have an answer to what went wrong...

I have the Captivate and my girl has the I9000M. I am definitely not new in flashing, just find it very interesting that after flashing Doc's V6, the Bell APN still remained and the boot screen still has I9000M.
Did Bell do something to the phone to prevent people modding it?
So far, my gf didn't complain about corrupting SD. She got hers like 3 weeks ago and the battery production date is Oct 2010. The phone even has 3 button download mode working out of the box.

Okay so with all the excitement and multiple upgrades of docs rom I made a boo boo.
I flashed a wrong kernel (BLN) using CWM and the phone would not start and could not get into CWM. So I did a flash to UGJG8 and then restored to dock.
Things would work fine for a few hours and then I would get errors, my internal SD card was intact, however my internal available memory was 0. I repeated this process with the same issue, finally got fedup and reparteed with the 512 and it all worked for a few hours and then internal and external all said unavailable.
Now when I boot It goes to the 19000 screen and then shuts off.
However, when I load UGJG8 with my external SD it boots to android and none of the SD cards are available, but internal available says 1.85.
I am trying different things as I want to try and figure out whats going on, any suggestions?
P.S. I strongly believe it has something to do with odin and/or pit files, i.e. software fix.

Aren't those 2 the "Internal Sdcard Corruption" indicators ?
Boot into recovery. What do u see ?

Yup, I know it is the internal SD card corruption.
Ohh well.... back to the bell store
P.S. I want to highlight that all of this started once I used odin, till then I was using froyo for over a month without any issues. now it might be a coincidence but I dont think so!

I won't use odin if I don't have to. Il use cw instead

Help With Darky's Rom 7.6 and Initial Build

I will explain in as much detail as I can what my problem is.
I am looking to install the Darky Gingerbread Rom, I have already downloaded 7.6 along with the CWM(Update zip)
I am currently using the following firmware
Firmware Version 2.2
Baseband Version I9000XXJPM
Kernel Version 2.6.32.9 / root9(at)sep-42 #1
Build Number FROYO . XXJPM
I have a copy of JM8 which I downloaded today and the RAR contains a Modem & PDA file, which if my memory serves me correct, these are 2 of the files i need along with the CSC & Pit File, which I also have.
From what I can gather I need to run JPY to install Darkys Rom (Correct me if I am wrong) so I downloaded a copy of JPY only to discover that the RAR only contained 1 x file called JPY_JPY_JPY. Tar. At this point I am now stuck because I am looking for a PDA & Modem file for Odin3 v1.0 to install.
Please help me as I am getting frustrated as I have tried all day in my quest to get this on my phone.
Many Thanks in advance and Happy New Year to all
Best Regards GTi9K

yes u could use a 2.1 rom or for example hardcores kernel both flashable with odin there are other kernels just read the corresponding threads to be sure what they do(lagfix...) disable every lagfix backup efs and apps(u will perhaps need to flash again) and be sure u have 3btn combo working...
Sent from my GT-I9000 using XDA App

I think you are new to the community so I will be as basic as possible,
1) Flash XXJPY, you only have 1 tar file that means you flash it with putting as a PDA in odin, and put 512 pit in the PIT section. Then once flashed successfully, let the phone boot then turn off go back to download mode and flash hardcores k12 kernel , just search it on xda in the top right bar. Then flash that in odin and again you will only have one file so place that in pda BUT DONT use a pit this time. Now place darkkys rom in your sd card and power off your phone. Hold volume up, home and power button same time until the screen lights up saying i9000 to go into recovery, select install zip from sd card with the home and volume buttons, then choose zip and select darkkys rom then once install complete, go back and reboot. You are now om darkkys rom. Happy new year

[Q] Having some (basic) questions about i5800L

Hi all,
I've just got my new i5800L, and I've already rooted it with z4root. Here are my qs:
What's all that of XXJPM and all that stuff? Which one should I use for mine? (actual one is I5800LVIJG7 (Eclair)).
Is there any way of doing a nandroid (full copy of the actual rom which can be flashed easily) so if I mess things up or want to get back to Eclair I'd just have to flash it back?
I guess that's all by now. Thank's in advance.

JPM is the latest froyo rom...you cant backup ur whole rom as if nw we dont have any alternative for this...check flashing guide in sticky and see vdos on youtube. ...happy flashing...

I've downloaded 2 files (2 diferent versions). One was a zip file with 3 files inside and the other one was a rar file with 4 .tar.md5 files. The zip i don't know how to apply it because odin will only take .tar or md5 files and in the other one I don't know what to do with all the .tar.md5 files. What should I do? :S

Thanks, now it's booting (on the samsung screen). I think it worked. But now it's "orangeized" XD. I'll keep looking for the right tar XD
PD: is it ok if it takes a while on the "samsung" (the one with the glow, after the GT-I5800l screen) screen? cause it's past a few minutes and still on that screen and I'm starting to panic XD
EDIT: It's been more that 15 minutes since it's stuck at that screen. What should I do? Please, second day with it and already screw it XD

Flash the JPM firmware...you shud get it as a tar package...a single file...
but sometimes u will have 4 files
1. bootloader
2. pda
3. csc
4. phone
dont ever flash the bootloader file in odin with pda csc n phone tar files...because the risk of bricking goes high...
just flash the 3 remainin files...n when ur fone has booted...just do a hard reset

Great, now it works again! Thank you a lot. And now I finally understand how odin works :-D
which custom rom do you guys recomend?

Don't forget the i5800L is different from the i5800, but the only difference is the 3G antenna frequency. If you install JPM you MIGHT have 3G connection problems, or then again you might not. You MOST LIKELY will see a battery life decrease because of this issue. If you want really badly to have Froyo (android 2.2) you can flash a JPM ROM. If you want your battery to last a couple of days, either wait for an american release of froyo, or keep your Eclair version.
I have a i5800L from VIVO, originally with JG7 as well. When I installed JPF (previous froyo release) I had issues with the 3G network, when I flashed Kyrillos custom JPM ROM i also had problems. When I flashed Lestatious custom JPF ROM I didn't have problems, and when I flashed clean JPM i didn't have problems either.
So really, its a question of luck.. although let me tell you, my battery lasted way way longer on the original JG7 firmware than any other release (including the JK1 Eclair, said to be the best Eclair released before froyo).
Remember though, if flashing separately (not as one package), avoid flashing the BOOT file or BOOTLOADER. Flashing this increases the chance of bricking your phone. Not flashing it decreases the change by 1000000000000 times.

Yeah, I can see that. I'm with Kryllos v3.3 and the battery only lasts like about 16 hours :S. I guess I'll go back to I5800LVIJG7 (The one which it came with).

Remember though, if flashing separately (not as one package), avoid flashing the BOOT file or BOOTLOADER. Flashing this increases the chance of bricking your phone. Not flashing it decreases the change by 1000000000000 times.

About that, if I flash the bootloader (with all the others too, of course), and it upgrades ok, then there's no problem, right? I mean, if I try to downgrade again, it'll work fine? (Yes, before I read the comment telling me not to flash the bootloader, I did it and it was successfull. But now I don't know if it'd make it fail when I'll downgrade to I5800LVIJG7 :S)

It's not about upgrading or downgrading. When you flash, pratically all the memory on your phone gets erased, which means you can upgrade or downgrade at will with no problems.
The problem is, when you flash a bootloader, and say, for example, you have a power outage, or your computer decides to give more resources to your MSN or winamp you have running on the background (or whatever else), or even there is a problem with your cable connection or a spike in power, or whatever other mishap that can occur, the bootloader might not be able to transfer successfully. If that happens, you won't be able to boot your phone. If you flash everything except the bootloader and something happens, you will be able to at least go back into download mode and reflash the files needed.
Basically the bootloader tells your phone to start. If that gets corrupted, it simply won't. If you avoid flashing this and even if the transfer gets corrupted, you can always do the process again by going into download mode (which is installed along with the bootloader)

Great, thank you so much

No, I haven't. I'm now in Kyrillos v5.7 and it goes great (battery consumption, performance, etc)

Remember to backup your IMEI so we may have one less "help my imie is 000000000" thread.

Go to terminal emulator and type this..
su
dd if=/dev/block/stl4 of=/sdcard/efs.rfs
Wait for few seconds. Then copy efs.rfs from sdcard to pc and keep it safe.

Bell Mobility Gingerbread Signal Issues.

I'm such a noob at this...I am with bell mobility in canada on 2.2 froyo and updated to gingerbread. I don't have root. Everything worked to the letter except my signal is weak to none. I used Odin3_v1.0 and these files...
pda_xxjvk_sbl.tar.md5
phone_xxjvk.tar.md5
s1_odin_20100512.pit
Everything works my wifi and all and checked network settings. So where do i go from here because i get 2 signal strength bars at most to a lot of nothing...please help thanks

for flashing modemn
go here
http://forum.xda-developers.com/showthread.php?t=1022445
and download the file and using odin update the modem only?? (KC1)
I can't seem to find a link for modem for kc1 for odin version
1. Fired up Odin,
2. Put the phone in download mode,
3. Hooked it up to computer,
4. Using the phone tab I selected only the bin file for the KC1 modem. NOTE:
I did NOT select the partition box or use a PIT file.
5. Hit the Start Button.
================
you can use CW version from
http://www.darkyrom.com/community/i...nstalling-a-new-modem-gingerbread-froyo.1960/
http://perka.zapto.org/
but
u said u can't access the recovery mode...

Here is Odin file for u KC1
Open odin , click on phone tab select MODEM.BIN and do not touch any other bottons , click start
File attached

ALSO AFTER YOU FLASHED IT TYPE IN DIALER *#2263# SELECT HSPA BANDS , MAKE SURE * IS IN THE (850 MHZ), CLICK MENU BACK AND CLICK AUTOMATIC , U SHOULD GET YOUR SIGNAL TO THE NORMAL LEVEL

Quick update...my signal at my house has never been strong but better than what i'm getting good signal in the major city...but i compared my signals in weaker areas to others and i am 2 bars less than everyone else...when i do this modem update is my gingerbread staying intact?? One of the links in the prior posting refers back to froyo. Thanks for all your help in advance.. i'll flash the modem tomorrow when i'm home and go from there. Just to add another question, now that I am in gingerbread firmware, should this phone get rooted? And if so a link to the instructions are would be great...thanks

Simply enabling 850 won't work.
Refer to:
http://forum.xda-developers.com/showthread.php?t=876391
You can use JPG, JQ1, JVK, etc, with 850mhz 3G ONLY if you follow these steps:
http://forum.xda-developers.com/show...&postcount=438
You MUST flash from an 850mhz base modem (UGJL2, TLJL3, UGJK3, UGJK4) to BVJJPD or BVJJPG, and then to your destination modem; specifically following the steps as noted.
