I have a SGS Captivate I have been using as a sports tracking device and as a music player for the past year. I now have a few questions before changing ROMs on it.
History >> Two years ago I soft bricked it while on CM9. Not being able to resurrect it at the time I purchased an SGS3 and set the Captivate aside for a while. I resurrected it using a KK4 Heimdall One-Click and immediately flashed it to CM10.1. Having been on CM10.1 for a number of months I upgraded the device to CM10.2. After doing so I noticed the bootloader was listed as unknown and the baseband was KG3. I have checked this in terminal emulator and using a "Samsung Info" app from the PlayStore. I've verified the KG3 modem is for the i9000. I checked in the updater-script of the CM10.2 I downloaded and installed and observed it being coded for captivate and for i897. So, I am not fearful that I downloaded the incorrect ROM.
I have known of the above discrepencies for months and have not been terribly concerned. I do not know if they could have something to do with the fact that I have not had a sim card in the phone since before I resurrected it. Even though I do not currently plan to use it as a phone I intend to have it in a condition to do so if needed. That, and I was interested in flashing a ROM I have seen recommended several times by @BWolf56, Gamerzrom Legend 4.0. The questions I have stem from the fact that I will be going from a ROM based on Android 4.3 to one based on 4.2.2.
To correct the bootloader and modem I intend to flash, again the KK4 stock ROM (Gingerbread). This will be with the Heimdall One-Click from the forums, Odin is not an option - I run Linux. Once installed I will verify bootloader and modem. Based on the Gamerzrom blog I will then install CM10.1 before installing their ROM. (This could be avoided if I were not going back to stock.) At each step I will wipe and format as indicated, I will probably wipe and format to excess.
[Q1] Is this the best approach to get to having the 4.2.2 based Gamerzrom installed from where I am?
[Q2] Should I not do this at all, the donwgrade, even to stock, could seriously damage my phone?
[Q1] Is there anyone who thinks I could safely shortcut the above by simply flashing the KK4 bootloader and modem?
(If I can still find a download on the forums.) This would eliminate going back to stock GB and then to CM10.1.
[Q2] Is there no reason to worry about the bootloader and modem? The discrepency is simply an artifact based on there being no sim card in the phone and I would be best off advancing directly to flashing Gamerzrom from CM10.2.1.

1: don't need to flash cm first but you do have to flash the ROM twice to repartition it then flash the gapps.
2: flashing stock should recover/fix your unknown bootloader issue but unless your imei is unknown, you shouldn't have any problem using as a phone if needed.
I do suggest flashing KK4 before going to GamerzROM to avoid any issues.

The imei is still present at least according to "Samsung Info" and using getprop in terminal emulator.
Okay, flash stock KK4 rom, no need to flash CM10.1, but flash Gamerzrom 4.0 twice.
I was getting CM10.1 from Gamerzrom 3.0 installation instructions for those coming from GB. I was thinking going back to KK4 would reset the partition scheme to GB. I guess the double flash of GLE4.0 takes care of the repartitioning back to JB layout.
Thank you.

That's exactly it, whether you flash cm or gamerz twice, it will do the same thing and repartition. Just don't forget the gapps after.

Thanks, I wouldn't dare forget GAPPS.
In fact, I have already downloaded both GAPPS and the ROM -- that was about 6 hours ago. I probably will not flash until Monday. :{
You know, I am a bit surprised at how regularly posts are made to the Captivate forum. More often than I would have expected.

While it's an old device, it's really great and some of us keep supporting it
Mixed Results with increased understanding
Well I went through the process I outlined above, or tried to do so.
I downloaded a One-Click stock rom, android 2.3.5, from this thread. It is actually the same leaked stock rom I used two years ago. I flashed it twice per instructions to get the bootloader, doing so to correct my unknown bootloader issue. After this was installed I used a "Samsung Info" app to verify bootloader and modem. The modem was KK4, yet the bootloader was still unknown. I repeated the process twice more with the same results.
Rather than download a different stock GB rom I proceeded with the remainder of my plan. I flashed Gamerzrom Legend Edition 4.0 from here on the recommendation of @BWolf56. I wiped, formatted, and then flashed twice as he recommended. The ROM didn't boot, but not to worry I repeated the process. Still no boot. I next went ahead and flashed CM 10.1.3 and booted into it. The bootloader was still unknown and the modem was now listed as KG3, an i9000 modem, again. My guess is CM did this since this how it was listed before I went back to stock. I now went back to Gamerzrom and successfully flashed it. (Still showing bootloader unknown and modem as KG3.)
I am setting up the phone this evening. So far in addition to installing ROMs and adjusting settings I have verified wifi works. Later tonight I will be testing the GPS and bluetooth. With the "wrong" modem my results could be decremated, but I don't expect them to be. When I was previously on CM 10.1.3 and 10.2.1 and on the KG3 modem all worked. Bluetooth, wifi, and GPS worked that is, I didn't try calls because I wasn't using it as a phone and didn't have an appropriate sized sim to borrow.
If I need this device as a phone I will first try it as is with bootloader unknown and modem as KG3. If that doesn't work I will flash an i897 modem, probably the KK1 modem, and see how that works. If that doesn't do the trick I will try an earlier GB stock One-Click rom, either KK1 or KJ3.

Modem doesn't affect BT so it should be fine. It's odd that Gamerz didn't boot but glad it turned out fine. Also, having a different modem won't change anything about the bootloaders but that being said, I highly doubt it would stop you from using it as a phone.
You're seeing I9000 modems cause the ROMs were often built off the international version of the Captivate. Both I897 and I9000 work well on the device and you can flash whichever one gives you the best results in terms of networking (which you don't seem to be using anyway).

True, the kernel controls BT and wifi. I'm not sure why I was mentioning BT w/ modem.
I think I didn't organize my thoughts too well in that last paragraph. Closer to what I meant was that if needed as a phone I would try it as is >> unknown bootloader and KG3 modem. If I had any troubles with it working I would try a different modem. This is where I was erroneously thinking that the i9000 modem may turn be a problem. If that didn't fix it then I would go with another stock ROM to give another go at fixing the bootloader issue. I actually think/hope it would work as it currently is. The phone has repeatedly booted, so at least the sbl (?) secondary boot loader partition is intact.
BTW, the GPS seems to be working well, even though I have a 10/08 build device. Bluetooth, on the other hand, is not pairing with my Linux laptop nor a cheap bluetooth speaker. The same held true when I was on CM 10.2.1 with the cappy. Both, the laptop and speaker, pair with my SGS3.
Could the reason the Gamerzrom didn't flash straight off is that I was coming from a stock TouchWiz 2.3.5 rom instead of from any JB rom? Thank you for helping.

BT not working can be cause it wasn't updated in so long or kernel issue. Or could simply be that it doesn't work with your specific devices.
I flashed mine off stock KK4 (same one you flashed), tried to boot without flashing it twice, which of course didn't work but then went back in recovery, re-flashed and it booted just fine.

I have a Bell SGS, GT-I9000m. I'm considering installing hardcore kernel only, i.e. no custom ROM. If later I want to revert to the stock kernel, how would I do that?
Thanks for your help.
Sent from my GT-I9000M using XDA App
I'm not quite sure if it is possible with the stock-kernel but if you can make a full backup (like with CWM) you could restore it later. But why do you want to get back to stock-kernel?
If the backup-possibility does not work you have to find the stock-kernel for downloading and flash it via Odin or you have to flash the whole stock-ROM with Odin.
Thanks for your answer. I can't make a Nandroid backup while I'm on stock (because I can't install CWM recovery because I'm on 3e stock recovery, not 2e)
I'm not sure why I would want to go back to stock... Maybe something goes terribly wrong? I guess I just wanted to know if it was possible.
Last question: when you say I would have to find the stock kernel, is that just Google, or are there sites/repositories out there for this sort of thing?
Sent from my GT-I9000M using XDA App
I should add, the site/repo question is for kernels and stock ROMs...

Don't know if you'll find it anywhere cause nobody needs it.
Possible scenario
Alright, thanks for your help. I guess the one scenario that is bothering me is as follows:
1) Bell - FINALLY - releases their official Gingerbread update.
2) I've installed Hardcore kernel, which according to - http://forum.xda-developers.com/showthread.php?t=822756 - "works on all 2.2 and 2.2.1 ROMs".
3) Would I be able to install the Bell Gingerbread update with Hardcore kernel?
This is why I keep asking how I would revert from Hardcore because I obviously don't want to lock myself out of Bell updates forever.
It doesn't matter which kernel you are using when you are flashing with Odin. And Bell releases the updates later than Samsung, so you'd have the advantage of getting updates earlier with a 'free' firmware.
One solution to flash back the stock kernel is to extract the zImage (the kernel) from the stock rom and flash that with Odin or Heimdall.
But as far as I know having a custom kernel would not cause problems with installing a stock upgrade.
Done
I've installed Hardcore's kernel. Everything seems to be working fine, phone started up and picked up service.
I booted into recovery, enabled lagfix, turned on all of the recommended tweaks and then ran the Quadrant Standard. Things seem a bit faster, so I guess it's all good.
Next step, Darky's 10.1.
Thanks for your help, everyone.
One more question:
I did a Nandroid backup of everything (so data, dbdata, cache AND system). The restore option says "Be careful!". What's up with that? I mean, what's the caveat?
Thanks.
I've already made some NANDROID-backups, but never seen 'Be careful!'.
If the backup was succesful I wouldn't care about that.
*sigh*, I hate to keep adding questions on to this thread, but I must.
After installing the hardcore kernel and enabling tweaks and lagfix, I'm running into exactly this problem: http://forum.xda-developers.com/showthread.php?t=851970
My phone was extremely hot for a while, then I got a warning indicating that my internal phone storage was running low, etc.
Eventually, I found this file (/data/local/tsprsp) to be the culprit. I deleted it and rebooted and now my phone is fine. However, vibration just doesn't work at all!
Any ideas? Has anyone else run into this problem?
I was told that if you do a 'full' backup, in some cases restoration will fail with some error. But it depends on the version of the ROM you are using.
That is the reason why it is recommended to backup only data and if you want to restore, then first reflash your rom, then restore the data.
Thanks, zsori. That explains the "Be careful!".

you will have to flash back a stock rom via odin if anything wrong happen during the flashing of custom roms, although chances are low if you follow the instructions carefully.

Which Gingerbread?
So I'm continuing my quest to learn more about all of this custom ROM flashing stuff. And I wanted to get gingerbread on my phone... So I figured I'd just get an image from samfirmware.com and flash it. But then, I went here (because I was also interested in Darky's 10.1 so I was reading their guide): http://www.darkyrom.com/community/i...-darkyrom-gingerbread-jvh-noob-friendly.3080/
It says that flashing "Ficeto_JVH_I9000_Odin" will get me a stock Gingerbread. My question: what's the difference between flashing an image from samfirmware.com or flashing "Ficeto_JVH_I9000_Odin"? How do I know which to pick?
In all my browsing/reading, I realize that there are 3 "separate" parts: kernel, modem and then the "ROM". Ideally, I want to keep my modem as is... What does that correspond to in Odin? I've tried to find what "PIT", "PDA", "PHONE" and "CSC" represent in Odin, but I'm not sure I got it right. PIT = Kernel? PHONE = modem?
And finally, how do I know if a particular kernel is compatible with a particular ROM?
Sorry, I know there are lots of questions there. But please help clearing up a n00b's confusion. Thanks.

you got it wrong.
PIT is for mapping the partitioning of the phone. In most cases you should only use 512 pit file. and only use it when you want to wipe the phone.
the three parts is "pda" (which is the rom), "phone" (which is the modem), and "csc" (which is the carrier customization and apns)
the kernel is in the part of pda (the rom)
check the thread in xda of the kernel to see if its a gingerbread kernel or froyo kernel.
hope this clear things up
Yes, that helps. That's really good to know. So now, in Darky's guide to flashing Flash Ficeto_JVH_Odin, I see that only PIT and PDA are specified. This is reassuring, knowing that the modem and carrier stuff isn't touched.
Many thanks.
There are firmwares with three parts (Phone, PDA, CSC, including bootloader) and with only one part (PDA, no bootloader(?)). The one-part-FW is just an 'update', the one with three parts an 'upgrade'.
I'm running Overcome currently. Is it possible to flash to a stock system from Clockworkmod, such that the system I'm running is stock?
I don't need the tablet itself to be bone stock, but I'd just like to switch back to the stock system, with none of the Overcome modifications.
Ideally, I'd love to be able to keep Clockworkmod and still use Clockworkmod to flash modified kernels. Even more ideally, being able to stay on ext4 would be great.
The reason I ask is I've been seeing some weird bugs lately, mainly with my AT&T wireless account mysteriously breaking down and not working until I reselect the APN and reboot, as well as 30 second hanging on boot, and I'd like to try stock again to see if those problems go away.
I think you can apply Clockworkmod afterwards, if you have already successfully applied Overcome. This means that you have Odin ready on your PC, drivers for USB ready and your tablet is rooted.
I applied stock_safe ROM included in Odin package to fix my freezing tablet. Lost CWM, but right now I am looking how to apply it separately of Overcome.
edit: I think I have just found it on the market, you have free and premium version. I think this guy deserves free coffee, so let's buy premium.
For my at&t tab i use JQ1, which is stock gingerbread, then i applied the CF-Root v3.3 to have root and CWM. Then I flashed Dip7 kernel for speed improvements.
I was having the lag issue too so I reverted to this set up, and I really like it.
As for the connection issue, you have your apn correct, but remind me what modem you have? Maybe an experiment is in order.

Okay, so I can flash to Overcome's stock safe (which will change me back off of ext4), and then using Odin flash one of the stock firmwares, and then apply CF-Root to get root/CWM. Does that sounds right?
It's actually pretty disappointing that AT&T still hasn't released or even announced its own Gingerbread update yet, which I hadn't realized while typing this, since I had really wanted to flash back to stock to fix the AT&T connection issue, but it may still work on other firmwares. Going back to Froyo seems like too much of a step backwards.
I'm currently on the KM2 modem. What do you recommend?
Flash stock safe then flash CF root, overcome kernel (only kernel), or Koxudaxi or dip7 or whatever pleases you then flash the modem that works best for you.
OK, so I ran through all the guides and searched through what feels like a thousand posts. Here's my problem. I want to flash ICSSGS. Every guide I've read says I need to flash back to stock 2.1. I'm currently on the UCKK4 GB update. I used ODIN one click to flash back to 2.1, but couldn't get into download mode using any method (excluding JIG). So I used Kies to upgrade back to UCKK4. I can now get into download mode again. Can I just flash the bootloaders and a custom kernel from GB instead of being on Froyo?
No need to flash the bootloaders, you have the gingerbread ones thanks to kies, they work worth EVERYTHING so you do not need to ever flash bootloaders again.aahs i digest you don't, Cause flashing those is the only tine you cab hard brick.
Flash corn kernel with Odin right now on gingerbread, then boot into recovery factory reset and format /system, and flash the ics ROM twice. Bingo bango you're done.
Thanks. I'm just switching from a Sony X10 so things are a little different here. Every guide said start at 2.1 so I didn't think i could flash from GB. I want to try ICS, but the X10 builds are still alphas.

Most of the guides on here are getting dated. But for the Captivate, once you have gingerbread bootloaders you can flash pretty much anything from anything. Exceptions would be Cyanogenmod.

some people have reported that gingerbread bootloaders work with Cyanogenmod
He meant flash from CyanogenMod or any other MTD ROM to BML ROM
Again, thanks for the info. Maybe I'll write an updated guide after I get accustomed to this phone and ODIN. Flashtool for the X10 definitely spoiled me.

I have successfully flashed about 10 roms while having gb boot loader they include 2-3 version of cm7, two version of miui rom , and many more gb boot loader can run any older or newer rom on captivate no need to downgrade bootloader
I'm a quick learner. I just switched over from a Sony X10 that was running a MIUI rom. My wife bought an iPhone so I took over her phone. I'm still learning the ins and outs of the captivate and how it works. I'm loving this phone. It's capable of so much more than the X10. I'm also loving this ICSSGS rom. It's smooth as butter.

Hello!
I do not understand what the problem is, I've had my SGS for 2 years, been flashing it regularly from GB to JB and never had any problems.
I decided to upgrade my slimbean rom because I was getting a IMEI error message even though everything was working fine.
Reading in the forums I understand that flashing back to an official samsung firmware would recover my original IMEI.
Which I did and saved /efs.
Then through CWM recovery I flash the latest slimbean 4.2.1.
Everything goes fine.
But when I boot up I don't get prompted to unlock my sim. So I check in my phone and have "unknown" under baseband.
I've tried flashing just the modem.bin --> still modem doesn't appear.
I've tried reverting to my older ROM --> still modem doesn't appear.
I know I have the correct ROM for my phone, but I cannot figure out why my modem is not being taken into account.
The phone works perfectly under GB official firmware btw.
Anyone has any ideas would be greatly appreciated.
Cheers

I do not understand what the problem is, I've had my SGS for 2 years, been flashing it regularly from GB to JB and never had any problems.
I decided to upgrade my slimbean rom because I was getting a IMEI error message even though everything was working fine.
Reading in the forums I understand that flashing back to an official samsung firmware would recover my original IMEI.
Which I did and saved /efs.
Then through CWM recovery I flash the latest slimbean 4.2.1.
Everything goes fine.
But when I boot up I don't get prompted to unlock my sim. So I check in my phone and have "unknown" under baseband.
I've tried flashing just the modem.bin --> still modem doesn't appear.
I've tried reverting to my older ROM --> still modem doesn't appear.
I know I have the correct ROM for my phone, but I cannot figure out why my modem is not being taken into account.
The phone works perfectly under GB official firmware btw.
Anyone has any ideas would be greatly appreciated.
Cheers

Did you restore the /efs folder backup? or is there content in /efs.
Yep I copy back the /efs and no change.
I checked the imei file and it's identical to the backup one.
Size and permissions are also identical, which makes me think the problem is not coming from there.
Today I flashed the Cyanogen nightly and my phone works.
I liked better the slimbean ROM as it is incredibly fast for our lighter hardwared beloved SGS.
Well I found a solution. Not very clean but at least I got Slimbean ROM back on my phone.
CM10 is just soooooooooo incredibly slow on SGS it wasn't functional. 60 seconds wait to go from 1 screen to another. Camera getting stuck on a picture and had to wait 1 to 2 minutes for image to refresh...basically unusable.
So anyways I flashed clean to official GB stock ROM.
Then flashed CM10 ROM.
And then on top of CM10 I flashed Slimbean ROM. With ofc all the necessary wipes everytime.
This time the baseband was recognised.
I don't know what the pb is, but apparently you cannot flash from a GB stock ROM directly to Slimbean.
Cheers all!
I have an AT&T captivate and when I install any rom after stock I have no signal and no apns available (unless I am on stock then I have great signal). It will let me manually enter an apn but it will not stick. I backed up my efs folder from KK4 and replaced it once I went to new rom. I have tried it from stock going to GB, ICS and JB with no luck at all. I can get any rom to load through CWM but no matter what I get no signal and have been reading and searching for 4 days now. Any help would be greatly appreciated! NJD316

Do you have a modem? What does it say in baseband version (in about phone)? If not, that would be the first thing to look into (flash one).
Is your IMEI fine?
All is back to stock (using Odin) and modem works and imei is good. I can make calls and use Data and WiFi no problem and it picks up my MicroCell. It is when I upgrade to GB, add CWM and try to go to ICS or JB. I have tried CM7, CM9, CM10, and SlimBean 4.2.1 and 4.2.2 and any time I upgrade I lose APNs and it won’t let me add one.

Because you need to flash a modem after flashing the ROM. Those ROMs don't flash a modem, therefor, after you wipe, you have no modem.
I have tried several modems (6 to be exact) and every time I flash the modem shows in the baseband but stillk no apns or signal, WiFi is fine though.

APNs don't just appear, they have to be manually entered and saved.
I know apns don't just appear (on most roms) and they have to be entered manually, in the first post I explained that part . I do appreciate your help on this and your patience and I have had my share of modding my cappy and my sgs2. Basically = I can bring it back to stock (Froyo) and it works fine, if I upgrade to GB or later (to include flashing modems) it shows in the baseband that the modem is there but I have no signal, no apns show and I can manually enter them but they don't stick after saving. I have copied the efs folder that contains the imei and replaced it as many threads have said and it still does not work. I have gone through the process of stock Froyo to JB 4 times with different roms and results are the same.

Umm, can you try flashing Odin KK4 with bootloaders and see if they stick? That being stock GB 2.3.5
Been through the KK4 process and that didn't work either to get to ICS or JB.

KK4 is what you should be going back to stock with instead of Froyo, that way you don't flash Bootloaders over and over, pretty much removing the chance to brick your phone.
Once you have the GB bootloaders, to go back to stock, you should use KK4 without bootloaders. (As long as your signal and such is fine on stock GB).
Now, which modem did you try? On JB, you should be flashing the I9000 modems: http://soggycashew.weebly.com/cm7miui--ics-modems.html
I flashed the ugkg3 without any success. I will try the entire process again when I get home. Any particular modem you recommend before I try that one again? I am in Kentucky, USA and there are no points on the website map that is on the link. Thanks Bud.:good:

I can't recommend modem, sadly. They act different on every device and in every area. I have great results with JK4 in the past but it's outdated now.
SO my plan is to start with KK4 (without bootloaders) bringing me to GB, get cwm loaded, flash a i900 modem, make sure signal is good and then I should be able to flash a JB rom from there?

Almost.
If you're on Froyo, flash KK4 with bootloaders. From there, if you need to go back to stock, use KK4 without bootloaders.
Once on GB, make sure you have signal and all his good. Flash Corn kernel and flash the JB ROM you wanna try as per their full instructions.
Finally, try flashing some modems to see which one gives you the best results.
YOU ROCK! It was the corn kernel step. I went from Froyo to Slim Bean 4.2.2 in less than 30 minutes. Thanks Bud!!!!!
Help!

Hi, could you please describe in easier terms how to do it?
Yesterday I was able to upgrade it from 2.3.5 to 4.2.2 and I LOVED IT but got no signal no service at all... i had to take it back to 2.3.5 and today I will try to do it with another stable ROM instead of the nightly that I tried before.
Any tips for me? Thanks a loooot in advanced!
You got no signal and no service simply because you did not follow SlimBean installation instructions.
