You need to try to put your phone into download mode with adb. Download Android-sdk and get the the gingerbread stock odin for your phone. Take the Android -sdk and put in on the root of your hard drive on your computer. The go to the start menu on you computer and type cmd if you are using window. Which I assume you are. Ok in the command type cd\android-sdk\tools. Now have your phone on and plugged up to your usb. Then type adb devices to make sure the device is there. Also you will need to install the Samsung driver for your phone before you use cmd. Ok sorry I forgot that. Now after you adb devices and you see your phone . Type adb reboot download. Your phone should now reboot into download mode. Open up odin and run it.

Plug your phone into your computer, press Power,Volume up and Volume down all at the same time for 10-12 seconds, then you SHOULD be in download mode, as long as your phone is functioning at the moment you shouldn't need all those files, although they are quite helpful in the end as you can use adb for lots of things. Hope this helped.

Learn to use the real ADB from the SDK.
Also, if your phone is not rooted, the reboot command does not work.

For those who need to know....
If you have a 1008 build (like me). Most of the time the buttons on the phone will not work. (Most meaning if your running certain custom ROMs the functionality returns until you go back to stock.)
I end up having to use ADB to reboot my phone into download or recovery in between flashing back to stock and going onto the new ROM because the buttons never work when I want them too, and it's become almost second nature to me
In order for ADB commands to work - you do NOT need your phone Rooted (otherwise I'd have been fubard a long time ago). You do need USB Debugging turned on or the commands won't work.
Also.. you only need Root/SU if you plan on using ADB shell commands and wish to play within the phone itself. Def not suggested for those who never have played with a shell before.
If you're going to be flashing different roms then next time you go back to stock use this one:

I've used it on my 1008 captivate probably 100 times so I know it works

Wrong the one that came with the phone will work for download mode everytime. it is the other 3rd party usb cords that do not work sometimes.
I have a 1008 batch phone and have never had a single problem flashing ROMs.
So, I bricked my Infuse last night at work when I tried installing MIUI from ROM Manager. I've been trying to unbrick using gtg's Ultimate Unbrick method, but no luck. I believe it's something to do with the Samsung Drivers since my phone is not recognized in Odin. Tried to redownload the Drivers from Samsung's website, but still doesn't work.
Any ideas?
BTW, running Windows 7 32bit
why would you install a rom that's for a different phone?
can you boot into recovery mode? did you try the "jig"?
Didn't think there would be a listed ROM in the manager if it wasn't for the phone...
Won't boot into recovery at all, Samsung pops up, then it goes blank, and Samsung pops up again. It loops like that until I pull the battery.
Was hoping to avoid having to buy something then waiting for it to arrive, as I need the phone working asap.
the reason other roms pop up in rom manager is because you are using the galaxy recovery. unless it says "for infuse" (there is only one, gtg's rom) it wont work. bummer dude. im all out of ideas, never had this happen. hopefully someone who's been through this can chime in and provide some info that will help you.
on a side note, why cant you take it to an att branch and have them exchange it for you?

I hope u have USB debugging turned on. If yes, u cud try this:
1. Download and install android SDK (search google for this if don't know how to).
2. Open a command prompt
3. Type in "adb reboot recovery" without quotes, and don't hit enter
4. Connect phone to PC
5. Turn the phone on
6. Wait for "samsung" to appear, and hit enter in command prompt
7. If it says "device not found", use the up arrow to get the command from history, and hit enter again. At some point, it should issue the command to the device.
8. If u can get to recovery, well, u have a way to now try to flash any other ROM.
Don't give up. Samsung has strong phones that could be got out of soft bricks most of the time.
Delete/reinstall the drivers.

Just tried Diablo's method, and it tells me command not recognized...
Download Kies on your pc to have it recognize ur phone. Run odin. Put ur phone in download mode (pull out battery, put it back in, hold both volume buttons down, plug in ur usb) and use gtg's unbrick.

Tried Kies before and it would never recognize the Infuse. Should I pick Galaxy?
UPDATE!!
Redownloaded Kies and installed the drivers (for the 500th or so time) and now Odin is recognizing a device. It's showing [COM3] instead of COM## but I'm letting Odin do its thing. Seems to be working... Crossing my fingers!

You need to buy a jig, that will solve the problem.
The jig is less than $10 bucks shipped if you buy it on ebay.
Here is the link:
http://cgi.ebay.com/Samsung-Galaxy-...0563626533?pt=Cell_Phones&hash=item20ba3eba25
Easy to use.. all U do is pull the battery, plug the jig into usb port on the fone replace battery and you will see the big triangle saying "Download" then unplug the jig and load odin.
Setup the pda/phone/pit/csc files in odin3. Then plug in the usb cable from computer to the phone making sure that where odin says "com" that it is highlighted yellow. Then click start in Odin and wait til it says "reboot" after that you will have a working phone with stock froyo 2.2 . Don't change any default setting in odin.
Use the "Ultimate Unbrick" rom - Here is the link:

I got it unbricked now, problem was the drivers wouldn't correctly install on Win7.
But, now I have a new problem. Just put 3e recovery on and flashed CWM, only to get bricked again (no problems unbricking this time, taking longer to type this than it took to unbrick...). Also, sometimes apps refuse to download from the Market. I tap "INSTALL" and the notification pops up saying downloading, but then it disappears and nothing happens, its like I hit cancel. I'm going to call it for today and get some sleep. At least the phone is usable now! :-D

That means u do not have android toolkit installed on ur system. You should install it first for the adb commands to work.
I would recommend downloading and learning the basics of adb. This could be a life saver in many no-so-happy situations.

Had this same problem and it turned out to be a hardware problem. There was no gix for it. Also youll notice that gtgs recovery includes a preroot. If you need to send your phonr back like i did youll need to get that off. It was tricky for me because the hardware was so screwey. I got it off after a few reboots of the phone and a couple of trys with superoneclick.

Originally one cm7, tried out cm9 but apparently i never got the bootloader right so i was getting rainbows. I tried to switch to emancipation and that loaded up fine. went and made one more attempt to cm9 but no luck. i am not stuck at the samsung logo. If Odin connects it gets to the step that says setup connection but never moves past. What are my options? I don't even care what rom i'm on as long as i can use the phone. cm9 gives and error if i try and flash. i can still access red CWM. emancipation will flash and say complete but if i reboot it just sits as the samsung logo. i checked mounts and no matter what i cant mount system which i think is my problem. i can no longer see the phone from my pc either. so i don't believe i can get another rom to it from the pc.
Any help is appreciated, screen shots or explanation for dummies is much appreciated. I've done this before but have never been stuck like this where i couldn't get back to a working rom stock or otherwise.
Thanks,
Joe
Try qksters heimdal to stock and see. If no luck, try Odin again(gtgs unbrick)but try with every USB port until it works. Sometimes Odin likes to prefer a certain one. Anyways, I prefer using the heimdall package. A lot more easier in my opinion
Try a pizza taco sometime, if you don't know what it is, look it up then
did you wipe user data,cache,and delvic
yes. also finally got hemidall to load on the home pc but phone would never connect. even if i went through cwm and put it into download mode.
Kies wont see phone ive tried that too. pc sees it and load drivers but it wont connect. i cant even see it as a mass storage on the pc anymore. gunna try odin from my work pc. If anyone can help it would be great i need to fix this asap as im in the middle of purchasing a house and have quite few people im going back and forth with.

got odin to work. i needed a different usb cable.
I had a similar problem, except I was unable to flash any from after attempting to flash cm9. Im on vacation away from my computer so I was unable to Odin, I just kept using the three finger method to get into recovery. And kept trying to flash a different roms always getting stuck at the Samsung logo...after about 1-2 hours of continuesly flashing i was finally able to flash a rom-after my phone finally booted up I booted into recovery which was now red again and instead of flashing the kernel I just flashed cm9 again. Got stuck on Samsung logo booted into recovery which was once again rainbowish and reflashed and then I booted up into cm9!!!
So basically for those who are away from a computer just keep attempting to flash-it worked for me just took a looooong time

I am in desperate need of help .. I am not a noob to flashing roms and rooting, however I have a one-off situation w/ no precedents to my knowledge. I have read these and other forums for days to no avail.
I was flashing Infintium Rom 4.0.4 from MIUI 2.3.6. I followed the steps listed in the post (http://forum.xda-developers.com/showthread.php?t=1661690). After flashing I rebooted and waited however the phone was/is stuck on the Samsung logo and never progressed. I then pulled the battery and attempted to go back to recovery mode to reflash make sure I did flashed correctly. However, upon going back into recovery I was greeted by the below image.
Clockwork Mod is extremely distorted and flat out unusable !! As I read further down it advised to use Heimdall (http://forum.xda-developers.com/showthread.php?t=1331381). I downloaded and attempted to use, however my PC (Which by the way is Windows 7 64-Bit) recognized the phone but the Heimdall software did not. I already had the right drivers for the PC and phone. After a few tries I deleted the files and reapplied them. On the 2nd menu after selecting list devices, on the drop down the option for Samsung USB Composite Device neeever ever appears. I also tried on a different PC that ddnt have the drivers and started brand new. Still, Heimdall ddnt recognize.
I also tried to flash numerous files including but not limited to GTG Ultimate Unbrick via Odin. Again, PC recognized USB connection however program ddnt. At this point, I do not know if it is because the status of Clockwork Mod on my phone, but I know it is not because of the drivers or the USB ports on my PC.
In addition to that, I have just scrapped the idea of flashing or getting in CWM and just wanted to do a hard reset (While phone is off held Vol down and Power, once started released power and contimued to hold Vol down. This should take the phone from the Samsung logo to an alt menu that will give the option to do a factory reset. But again w/ my luck .. that screen neeever appears.
In short I have tried at least 3 different ways and many maaany variations to get the phone back into recovery or into a full boot and had NO success.. Please help and ask as many questions as needed to diagnose and resolve this issue .. Thanx in advance and apologize in advance if posted in the wrong thread.
Are you placing your phone in download mode?
Remove battery and place it back.
Hold vol+ & vol- , and plug in the usb to your phone with the other end already connected to the PC.
Now see if Odin or heimdall recognize your device.

If neither Odin or Hemdall can 'see' the phone, then possibly you don't have the correct drivers installed...
Try downloading and installing these:

Then open Odin/Hemdall and plug your phone in again while in Download Mode.

The CWM screen is shot because you don't have gingerbread bootloaders, it will always look like that until to can flash the right ones..
Have you tried different cables, different ports, etc?
Sometimes mine would recognize.. sometimes being plugged in first then running Odin works, sometimes I would have to run Odin and then plug in the phone.. kinda a crapshoot...

I know I need to get the bootloader and a kernel on it however I cant = ( .. yet .. I have 4 different ports on my PC and have tried them all. i have tried phone on then run programs and programs on 1st then phone on and no new results.
I found this short video and it describes my exact situation .. please watch to futher understand http://www.youtube.com/watch?v=OHLUYckTlug
So u have odin and heimdal both on the same PC and drivers for them if yes then try this.
On the PC/Laptop uninstall all the drivers for samsung or any other phone and follow this.
Go to accessories> system tool> system restore and check the restore point where the drivers for heimdall were installed restore to a previous restore point after restore finishes install the drivers for Infuse and see now Odin recognizes ur phone, It should.
I had the same exact problem, do you have another phone on which you can install the same CWM recovery on? ...Because the clockwork mod recovery still works, it's just that you can't see it. So just flash a new ROM, by going back n forth between phones, clock how many clicks it takes to get to 'choose zip to install' then 'download' on the not messed up phone, then do the same on the screwy one, just keep doing that till u flash the new ROM.

hi im pretty new here a friend of mine gave me her lg c800 mytouch to try and fix it for her.. not sure what she did she said she rooted the phone and the root was successful but i have a good idea that she doesnt know what she was doing..i will post a pic of the error screen im getting. but it says

now im far from a pro at this i know a lil more about computers and Ios devices..but ive rooted a few phones and to me it looks like she unzipped adb fastboot on her phone from her sd card??
ive tried holding F..A..vol down..and power..Nothing..
ive tried volume up .volume down and power still nothing..
BUT if i hold E..vol UP and power it brings me to a white screen that says S/W update
the big problem is the phone wont stay on long enough to do anything on the computer it stays on 3 sec. then reboots to same screen (computer says phone is unplugged) then phone just keeps restarting.
but the phone WILL stay on when i put it on the S/W update screen..but computer wont recognize the phone at all on that screen
ive tried the adb and fastboot commands but the phone wont stay recognized..it will recognize the phone and say thats its in recovery mode but when phone restarts it dont see phone no more..
well thanks ahead of time if anyone has any input or solution
and hopefully all this will make sense to someone lol
i think this pic will work.. if not ill try again
any ideas please?? or am i completely out of luck?

Yes In Adb device list it shows the phone and then says recovery..but after that I don't have enough time to type any other commands ..the phone is also recognized in "my computer" as removable device then when the phone restarts seconds later it says device unplugged ..and just keeps restarting on its own till I remove the battery...I just read on the forum in a post that Adb will recognize the phone if it's off but I remove the battery and put it back in and plug in USB and phone turns on and keeps restarting won't even let me turn it off!! I'm losing patience with this thing lol
But I don't get why the error mentions fastboot? Not my phone so if it's not fixable I don't really care but I'm just the stuborn type when it comes to fixing electronics ..again thanks ahead of time to anyone that helps cuz I'm completely lost on this one
Have you tried timing it to send a quick "adb reboot recovery"? If you can use fastboot, you can tell it to boot off a new, custom recovery img, without actually flashing it.

Normally, if you want to flash a custom recovery through fastboot, people will tell you to run 2 commands:
fastboot flash recovery nameofimagefile.img
fastboot reboot recovery
Since you don't have time to execute those 2 commands, you can tell it to just boot from the .img file, without flashing over your current recovery. (This is actually proper form, as you can test if the .img file works properly without damaging your existing recovery.) The way you do that is to 1st copy a recovery .img file to the root of your SD card, then execute the following 1 command:
fastboot boot nameofimagefile.img
Since you only have ~3 seconds, type the command in, and wait for the right instant to hit enter on the keyboard. If the command is successfully sent to the phone, it will reboot into that .img.
See if that works for you. Good luck.
