Back to stock please

tahrang · Dec 9, 2015

Hello all
I have an old Samsung Captivate, my kids were using it. Now they've new phones, so they left this aside.

Anyway, my son put cyanogen mod on this phone. But I want to put this back to stock. I tried the methods at http://forum.xda-developers.com/showthread.php?t=731989, but that didnot help, as I cannot yet go into download mode, as well as Odin or Samsung Kies does not recognize this device. It goes into recovery mode and shows CVM-based Recovery v6.0.3.1. There is no download link on this. I've tried vol down+power, then vol up+vol down+power, then just both volume buttons, but nothing helps.
The device is reconized by my laptop, and it is there under android devices in device manager, just doesnt get recognized by either samsung kies or odin.):
My all other samsung devices are working fine with the drivers I have.
I'm on Windows 10.
So please help me get this phone back to stock.
thanks

Did you pull the battery before attempting the button combinations for getting into download mode?
If you did that, this thread may provide another way for you to get to download mode.

Is there a specific reason you are going back to stock Eclair, android 2.1, instead of using one of the newer one-click stock roms?
Others are available here. But then, that may be where you found the link to the rom you tried.

Which bootloader and modem were on the phone while it was in use? Which version of CM?

tahrang · Dec 9, 2015 at 4:33 PM

I've not used CM on any of my devices, I always use stock rom, even after I root.
Secondly, I am loaning this phone out to my friend, and she's not very digital savvy. I want to give her the phone with as little customization done as possible, because that's what she'll be most comfortable with.
I'll try the methods on the thread you posted above.
thanks

Hello
Nope, nothing helped, the phone just booted into the home page.
thanks

I must have misunderstood what you said in the original post.

I thought you stated that the phone in question had cyanogenmod rom on it at one time, installed by your son. I also thought you said it currently had CWM Recovery, v6.0.3.1, installed. This could be important because some versions of CM ROM would require an update in the bootloader from the Eclair bootloader. Those versions would require an upgrade to the Gingerbread bootloader. This includes a re-partitioning of the internal harddrive. Supposedly the GB bootloaders will work with the Eclair roms

So far AT&T GB bootloaders have been backward compatible with all I897 (even I9000) Froyo/Eclairs ROMs. I have used I9000 based ROMs with AT&T GB BLs. Someone in CM7 thread claimed to use AT&T GB bootloaders with CM7 without any problem.

but if you are on the GB bootloader, why not try the GB stock rom, android 2.3.5?

Since you can get to the home screen, is the current rom fully functional?
What rom, and version, is it that you can boot into?
If it is CM, there should be an app named Terminal Emulator installed. If it is present you can run these two commands to determine the bootloader and modem that are on your phone:

Code:

getprop ro.bootloader
getprop | grep version.baseband

for bootloader, it says unknown.
for version.baseband it says [gsm.version.baseband]: [T959TLJL3]

When the phone bootsup, it shows cyanogen mod, then when I boot into recovery, it shows CVM Recovery, v6.0.3.1(and it says CVM, not CWM). So now I am confused what do I have on the phone?

You may have just given a valuable clue.

That baseband is from the Samsung Galaxy S Vibrant, a T-Mobile device, not the Samsung Galaxy S Captivate, an AT&T device.

Either someone flashed T-Mobile software on your Captivate. Or, you are trying to flash AT&T software on your Vibrant. I don't know if these devices and their software are cross compatible.

Could you remove the battery and check on the underlying label the model of the phone?

It appears that a search of this forum has provided the solution.

didnt help, it just went to recovery mode.

Maybe these would help?

I tried out the samsung kies(old one) to see if that would connect. didnt connect.

Hello
I found I had GooManager installed. will that be of any help here?

dennisbarcelonaflyman · Dec 5, 2015 2 1 0

You said odin didnt recognized the phone right? I ll recommend uninstall the kies, that thing is always in the way and mess up the connection in odin

Thanks for chiming in. That sounds vaguely familiar, but I have had no experience with Kies in years. I use Linux and Kies will not work on Linux based computers. (I think I used Kies for my first upgrade on my Captivate, back when I was still dual booting Linux and WinXP. That was the upgrade from Eclair to Froyo.)

Yes, @tahrang those pics help answer some of the other questions I asked. They show that you have the a Jellybean ROM installed using a Gingerbread kernel (GB). I think it is the PACman ROM. Hopefully removing Kies, as Dennis suggests, allows you to get to download with one of the many methods suggested in the thread I linked to works, then you can flash a stock rom. I would suggest one of the Odin-One-Click methods that installs a stock Gingerbread ROM. I think they final three identifiers begin with K, ones like KH3, KK4, etc. Use a one-click that does not install bootloaders, it is not needed at this time.

still not going into download mode. always goes into recovery ):
I can access the phone via my laptop. From recovery, if I have a rom zip file on the sd card, can I flash it that way? Where would I find such rom(stock) zip file?
thanks

Yes, you can flash roms from CWM recovery. The One-Click files will not work for this. You will need to use a recovery flashable zip. You can find stock and custom roms in the Development sub-forum. With the Captivate and CWM recovery you need to put the flashable zip on the root of the internal sdcard, IIRC. I don't think it will flash the rom from the external sdcard.

Since your laptop will access the phone, did you use either of the adb methods to boot into download mode? They are described in one of the other threads I linked.

Also, you could use adb to flash the portions of a rom, whichever type it is - recovery flashable or Odin one-click. But you would need the adb/flashboot tutorial threads to understand that process and the commands involved.

tahrang · Dec 11, 2015 at 2:16 AM

can you send the link to the flashable zip files?
thanks

The link in the previous post will lead to them. The early posts in that sub-forum are to the one-clicks. The custom roms on the first page are flashable zips. It may take going through several pages to find a stock rom that is a flashable zip with a valid download link. I am on a slow connection with limited data, I can't test the downloads for you.

Back to stock please
