Okay before I get all the "Learn to google" or "Use the search function" let me just go ahead and say, I've searched all over the place before posting.
Okay I recently flashed my phone back to stock to get rid of a few problems. I tried to root with one click root and it failed when I tried to test it with sending the su command so not only was it not rooted it wouldn't allow me to use third party downloads So I am now trying to flash it back to stock again. Now Odin won't recognize my phone at all when its in download mode. I've tried reinstalling drivers and everything and it's like when I use Odin once it won't work again without reinstalling the drivers again.
It's hard to explain my exact problem but basically it's like the drivers keep resetting themselves or something where Odin won't detect my phone. And secondly my one click root no longer seems to work.
Any help would be greatly appreciated, this is getting very frustrating.
Edit: Now I am getting the "More than one device detected" error on the super one click.

You should try superoneclick (SuperUser) - It has never failed me
Also, you do not need to be rooted if you're on stock 2.1 Eclair - You can simply change the name of the ROM to update.zip, go into recovery and reinstal package.
As for Odin, I don't know what to suggest other than you could try using the non-one click one.

a) who said one click root will enable 3rd party apps
edit, you do want super one click root as stated above if you dont have that get it. the thread is by clshortfuse and usese the rage against the cage meathod, works on every phone
b) you need busy box before comands work, it is in the market
c)i dont know what your odin problem is, does the box turn yellow when you plug in the phone with in download mode? is this odin one click? odin one click+3button fix? odin files without bootloaders plus full odin? what version of odin? what series number is the phone under the battery? 1006?1007?ect...
Well the problem with moving the update.zip file manually is that my computer will no longer detect my phone regardless what mode my phone is in. And I was using superoneclick
Edit:
A) The Super one click root allows the option to enable non market apps, which has previously worked in the past but doesn't any more.
B) Can't get busybox without rooting
C) SGH-I897

Then it's most likely your computer and not your phone.
Try another usb port, cable;
unistall and reinstall the drivers;
restart your computer.
If none of these work, try on another computer.
After that, it could be the usb port on your phone.
Could I get a link or quick guide on how to uninstall and reinstall drivers.

Hehe, kidding
Umm - Try a different Odin.. Odin3 one click worked for me before.
You can try a non-one click Odin as well, sometimes it works when the other doesn't.
You don't have to connect to your computer either to flash a rom. download a rom with your phone ... Rename THAT update.zip on the phone ... Boot into recovery reinstall packages ... Its probably your computer like was said not the phone.
I reinstalled drivers, still not working. Any ideas?
Ummm when was the last time you made a restore point on your pc? Restoring from a few days prior worked for me when nothing else would, although it was just the dl mode driver that broke in my case ... You can't get it recognized at all ... But still woth a shot.

the latest version of AIO (3.0) uses heimdall instead of odin. i would recommend it
Okay downloaded the AIO tool box, looks pretty solid from what I can tell, will update to see if this fixes my issues.
Well I rooted with the toolbox and I when I try to run root required apps it says that my phone is not rooted or I haven't accepted superuser permissions. I do not receive a notification to accept these permissions however it does appear superuser is installed.
On the bright side I got all my drivers set up correctly.

Ok, I'm new here and a noob to the phone (only had it two days). I have been trying the SuperOneClick method, followed all directions and suggestions to deal with the looping issue, but no matter what I do or try I cannot get past the RATC loop (and yes, I've read hundreds of posts before asking). My cable and port are good, so I know that's not the issue. I have done the unplug, debug step, re-installed drivers, PDAnet, etc., but no go. The only thing I can think of is that I did a software update on the phone before I tried to root (thru the phone itself). Could that be the problem? Suggestions?? Thanks!
Never tried that method, always used the update.zip method.
Assuming you are on JH7:
1) Grab update below
2) Place on root of SD card
3) Reboot into recovery, either buttons or adb
4) Select reinstall packages
After the phone reboots, if it worked, you should see a superuser icon in your applications.
Good luck!
Thanks for the response.
I just wanted to let you know that I am super grateful for everyone's help! I ended up using the one click method and found a few other handy dandy files here. You guys rock! I'm a computer geek, but these phones mystify me for some reason - maybe it's because I'm so familiar with PC's and can do whatever I want with them. I'm so afraid of bricking my phone! Anyway, THANK YOU!!!!!!!!!!!

No worries. Most people here are friendly and helpful.
I also wouldn't worry too much about bricking. As long as you can get into download mode you can always use [STOCK ROM] Odin3 One-Click Downloader and Drivers CAPTIVATE ONLY to recover.
Worst part of flashing, restoring settings!
Recently, I had a very long discussion with some helpful users regarding how my market disappeared in the Android Themes section. After never recovering my stock market application, I finally just flashed to the cognition rom that is built for 2.1.
This was a huge risk for me because for some reason my phone is not found in Odin when it is in download mode. I have already tried everything to get it recognized, but nothing was able to get it recognized. If I were to brick my phone, I don't think I could fix it. I soft bricked it during the problem with the Market, but luckily I was able to get the phone working again through recovery.
I am thinking of flashing to the new cognition so that I can get my phone running on a 2.2 based rom and then quit flashing until I get a better phone or figure out my Odin problems.
I just have a few questions. I know a lot of people recommend flashing to stock first (which I can't do), while others don't flash stock. I should be able to just disable Voodoo and hopefully flash successfully to a new rom, correct? Also, what are the chances of a permanent brick? As long as I could get into recovery I could probably get the phone back up again without the use of Odin, right?

Back when I was really trying to figure the problem out (about 2 months ago), I was trying everything mentioned. I tried different versions of odin, 3 separate computers, windows xp/vista/7, front and back usb ports, multiple drivers, etc... The weird thing is that the phone is recognized in odin when it is on, which is how I was able to do a master clear on it. It is just when it is in download mode that it does not recognize it.
I eventually just gave up thinking that it was just a problem my phone has. The only thing I have not been able to test is using a different cable. I have been using the original OEM one, but I guess it could be the problem.
When did you bought the device?
if its within a year... you can exchange it... this looks like easy way out.

Unfortunately, It was purchased off contract and used from someone who lived near me. It is less than a year old, I just don't have the receipt for it. I would say that I bought it around the beginning of last August. They guy who sold it said he only used it for 2 weeks.
Ok, im just going to risk it... Phone should be flashed within the next 10 minutes or so.

When I first decided to flash to stock using Odin I had all kinds of issues. Everything from nothing happening to it only flashing halfway through. My problem turned out to be the cable. I was using a cheap microUSB cable at work. When I got home, I used the original cable that came with the device and had no issues.
Things you can try;
- Using a different microUSB cable
- Making sure you have the samsung drivers installed. If they are, uninstall and reinstall
- Try different USB ports with the microUSB cable. Some people say they had problems using the front ports while others the back ports. Worth a shot
- Try using a different version of Odin either newer or older
- If you have access to another PC, try flashing from there as well
Hope this helps
i've tried using both odins, the 3 click, and the one click. I've gone in with "AIO Captivate Toolbox" and also through the command prompt with adb.exe. It starts flashing and puts my phone into download mode, where Odin has it recognized, then it gets removed, but it never comes back like its supposed to.

Make sure Odin is up and running prior to going into download mode.
Will not fully reboot after flash back to stock ROM
Just flashed back to stock Rogers with Odin. Everything went OK untill reboot. It gets stuck at the ROGERS screen, then just shuts off!! and ideas?
I have been looking through the threads, and havent seen what I am looking for. So hopefully i will not get flamed to bad. I tried to install mikeymikes GR12, I got through the first stage of downloading the gingerbread rom to the phone through odin, but then it went south. I lost root and was unable to get back to the download screen. I then tried to use the all in one tool to root the phone, and that put me to the recovery screen where i could not use the ok button, just the volume up and down buttons. I just managed to get the download screen to come back, but i cant get anything else to work. Any suggestions on what to do, where to go from here.
Thank you for your help
I would go back to stock first. I believe your problem lies in the bootloaders. There are two bootloaders in the beginning and if you don't have the gingerbread ones installed, you won't install gingerbread properly.
I would use DesignGears One Click Odin to go back to stock and load the Froyo drivers. http://forum.xda-developers.com/showthread.php?t=731989. Make sure you open up Odin first before plugging in your phone, then hit the Start button.
Once that is done, you can try again, but read about getting the GB bootloaders installed properly before you try to flash a GB ROM. Any of the GB ROM instructions should get you there. Just make sure you know all the steps before you try it again.
Good Luck!!
I don't see why you would be flamed for your question. That is what Q&A is for and you are in a bad spot. The biggest thing to remember is to be as specific as possible when you post a question. This includes what you were trying to do, what steps you took, what was the result, when did the problem occur (which step) and what you have tried to do, if anything to fix it.
One more thing. It is always possible that the USB cable is bad or that the USB port you are plugging into (on the computer) isn't working properly. You might also want to plug into a different USB port.
Sorry these posts are broken up, but as I'm coming up with ideas, I'm posting.
Here's something you should try:

10-4. My next question is: where do I get froyo from. Kies sees my eclair version as unregistered, so it wont update. And my ota sees an update is needed, but when i tried, the area im in has crappy signal, so the update failed and now i have to wait 24 hours to do it.
Any suggestions?
Thanks again
are you planning on flashing a custom rom?
if so updating to official froyo is A HUGE WASTE OF TIME
EDIT:are you Canadian by chance? if so check this thread:http://forum.xda-developers.com/showthread.php?t=979133
I only plan to root the official froyo right now, that is what I had before I jacked it up. I am not Canadian.

Going on official froyo will get you the signature failed error (which you need the 3e recovery fix if you ever want to flash a custom ROM).
So, basically, if you want more than 2.2 official release. We suggest you don't update. If you're perfectly fine staying on 2.2 Froyo, then there's no problem lol
As for Kies, you shouldn't have any problem using Kies mini. Other than that, there is a 2.2 flash around here. I'm sure you'll find it doing a little search
I had root on my official froyo for a couple of months without a problem. Right now i cant get my phone to go into download mode, it only goes to the battery screen. If i can get to download i can make some headway

If the battery pull way isn't working. You could always go read on abd. It send SU commands and you could get your phone in downlaod mode that way.
Is there an easy way to get adb without getting the sdk. I downloaded the sdk and it keeps saying i need java, when i download the java crap it says the same thing.

Hello, I've got a Galaxy S, and it works great apart from the usb port. My pc (and others too) isn't able to recognise it. I mean, it detects the phone connected but I can't go further... Already tried with many versions of samsung drivers, kies too, windows 8, 7, xp... It seems that usb port is fault.
So the question is, since there's the 3a recovery on it, is there any way to root, and install CWM on it, without using a pc?
Or am I stuck on 2.3.3?
I've already tried zroot and similars... They just don't work.
Sorry for my English, and thanks to everyone

I think you have to find how to "downgrade 3e recovery to 2e" without usb (odin or haid..)
take a look here:
http://forum.xda-developers.com/showthread.php?t=788108
or search on google "downgrade 3e recovery to 2e"
After some days of research, I'm about to give this up...
The last option was downgrading to 2e recovery. No usb working, no root, 3e recovery doesn't let me flash anything.
I haven't found any official/certified/signed firmware released by Samsung which works on 3e recovery, and OTA update doesn't find anything.
Firmwares from sammobile aren't signed, I've tried, they don't work.
Apparently there is no solution apart from getting the usb port fixed, if I want to mod the phone.
Anyway, thank you all!
Unbelievable, but finally I've solved everything
I've just spent an hour scratching the microusb port on the phone, again and again, and now I'm running cwm and rooted 2.3.6
Again, thank you all
Sometimes it is really unbelievable
Small reason and great effect :good:
But it`s perfect when it not works ,fine !!!
So now you can go through to 4.2.2
