So, I was trying to flash my captivate back to a stock rom using odin3 when it errored half way through. Now my phone will power on, but the screen is just black. No recovery mode, no download mode. Nothing. Is there any coming back from this?
Sounds like it may be time to make yourself a jig. Have you tried pulling the battery and putting it back in, then holding vol up and vol down when plugging in the usb cable?
If you haven't already, try taking the battery sim card and memory card out. Put only the battery back in. Start odin. plug the usb cable into your computer. Press and hold just the volume up and down keys. Insert the usb cable into the phone. Does that get you into download mode? If not, then do a youtube search for "galaxy s usb jig". It will take a little work, but you will get your phone working again.
I've tried all that except plugging in the USB while holding the volume keys. I'll have to give it shot. If not, I'll look in to that jig. Never knew what that was until now. Guess I've just been lucky, I haven't needed to know.
Wow. It worked. So simple. Thanks guys.

No problem..
I think my phone may be hard bricked.
I was trying to follow the steps in http://forum.xda-developers.com/showthread.php?t=1141550, when I ran into the situation I'm now in.
I followed all of the steps perfectly with the exception of rebooting to recovery, I accidentally rebooted normally. After it had started up and sat for about 5 minutes or so, I rebooted back to recovery. I reflashed the ext4 zip, then Black Ice ROM, and then Bali 3.1. I went to the voodoo menu and disabled both options and told the phone to reboot again.
It sat at the SGS4G screen for 20 minutes and I never heard linda speak during this entire time. I got tired of waiting and pulled the battery. Now the only thing I ever get is the SGS4g screen. I let it sit that way while I slept and when I woke up 3-4 hours later it was still on that screen. I've tried following the advice given in the thread mentioned above to put it back into download or recovery with no luck.
When I connect the phone to the PC instead of recognizing it, it complains about it and immediately makes the USB disconnect sound. If I leave it plugged in every 5-10 minutes or so it'll pop up the warning in the system tray again, and make the USB disconnect sound. If I unplug the phone from USB, the battery charging screen stays on. If I plug back in to USB at this point it'll make the sound like it's connected but never shows in Windows device manager, 'adb devices', or in ODIN. Any ideas before I call it a hardbrick and try to take it back to the store?

Press and hold vol up and down and insert the usb cord that will get you into download mode..
You are at a softbrick.

I've tried pulling the battery and putting it back in so it's fully shut down before holding the volume keys and connecting USB. It makes the USB connect sound and quickly makes the USB disconnect sound, gets the popup in my system tray saying it's an unrecognized USB device and doesn't go to download or a yellow triangle screen. Doesn't appear in ODIN or 'adb devices'. I've tried it this way repeatedly since last night.
I've also tried waiting until it's on the battery charging screen to pull the USB cable. It stays on the battery charging screen even though it's obviously not charging anymore. I hold the volume buttons anyways and plug the USB cable back in, and it makes the connect sound but it still never goes to download mode. I've tried it this way several times as well.
I've put my phone into download mode many times before so I can't imagine my method is wrong, I'm not doing it any differently than I ever have before. It's just behaving strangely. I've never had it stick on the battery charging screen before when I unplug the USB cable...

Hey. I had the same exact problem. I couldn't get into download mode...and thus no odin. Look in the bible. There is a guide on how to get into download mode multiple ways. I used method 2. After that, follow the guide to flash using odin, also in the bible. hope you get it fixed.

HAH SUCCESS!! I finally got it into download mode by pressing ONLY vol down and power. Worked like a charm. Pressing both vol buttons is what was killing me. I got into download mode with Vol Down and Power, and then had to uninstall/reinstall my samsung drivers. Odin now sees my phone and I'm pushing KD1 as we speak. Thanks a million everyone. I love this forum. Thanks to all who helped.

+1 on that. I wish penguin0609 would at least update the op of the issues with it or at least have mr clown close the thread and take the link out.
Hello, my name is Aaron. I see the positives and negatives in every situation.I got an android phone because I don't want to be restricted by apple. I have played with my phone one too many times and...this happened.
Accidentally updated my atrix 2 to 2.3.6. I then severely wanted root so I tried to flash back. I googled for fastboot tools and found one on this forum. When i tried to flash an img, it apparently did not work even though I choose this fastboot tool because it said it was for atrix 2 and had atrix 2 img's with it. Now, my phone is stuck in fastboot mode. I have rsd lite working on my old, crappy laptop. However the usb port isn't giving my phone enough power to even turn on.It only turns on when charging through the wall.I have the fastboot files. All I need is a way to get my phone to stay ON while plugged into my laptop. I will appreciate any help, no matter how good or bad the help is because it's better than nothing.
Everyone, I have been helping with this as much as I can thorough PM, but I think he has a low power USB port on the laptop he is using.
1) have you tried another usb cable that is not from Motorola?
Sometimes that helps in these odd situations.
2) Can you get ahold of or borrow a powered USB hub?
That might allow you get this up long enough to flash the fxz to get your phone back to stock.
P.S. he can't ask for help in the thread about the fastboot files, because he has less than 10 posts.
What do you guys think? any brainstorming would be greatly appreciated, and he can't ask for a warranty exchange, just don't go down that path.
Jim, I am willing to buy one, but I would need to know how much they cost and where I could get them from E.X. Walmart. Could you link me to one?
Do you have a close relative or friend that would let you use their computer? I would try that before buying a hub and it would also let you know if your laptop USB port is bad.

Here is a link for a powered usb hub. Now I am not 100% sure if this will do the trick, so I am hoping someone else has an idea, since I am not a windows guy, and I am guessing that your laptop is older and has lower powered usb connections.

Yeahh I have my best friend who lives right next to me. His laptop is newer than mine but has xp too,I just don't know if I could use it as it was his mom and dad's.
try connecting to the wall charger, power on if it doesn't go to fastboot automatically.
at this point hold both volume up+down and press power again, the screen will turn off
still holding the volume up+down press power and you should be presented with the options
Boot mode selection menu
vol up selects, vol down scrolls
Available boot modes:
Normal Powerup
Recovery
AP Fastboot
BP Tools
just press vol up on normal powerup
let the phone charge completely then use the fastboot files to restore but you will need to make some changes to the fastboot files to flash successfully
Be sure to flash the stock rom with RSD Lite 5.6 and usb drivers 5.2, use windows 7 to flash the rom in ap fastboot mode. All will be fine.

You will have to disconnect it from the wall and pull the battery, then put the battery back in and connect the wall charger and do the following, your timing will be critical, you might have to unplug pull the battery and do it few times to get it right:

Jim I know you're not a windows guy but do you figure i can copy all of the rsdlite files from my sh*tty laptop to my flash drive and put them on my windows 7 computer and have it work because the installer doesn't work on this computer and my laptop is very slow.
P.S. I found it that it's not the laptop's usb. plugged it into this computer and it didn't turn on.

You might be able to zip up the RSD's installed directory under C:\Program Files for the RDS lite app and move it to your Windows 7 machine, but if there are any registry checks in the application it may fail when you run it, and it might have issues, since it does talk to the device manager, but it is worth a try, just make sure you also install the drivers for the phone as well, here is a link for those:

These steps do not work. I do not get said options. I held the power volume up and volume down for 30 seconds and nothing happened. [EDIT] thanks for 32 bit driver maybe it will now charge on said laptop. Screw it, it turned itself off. This is unfix-able for me. I need to go back to ATT but my mom won't let me because she works for ATT.
If your battery is completely dead you can still charge it but you will need a old USB cable for this to work. Take the old cable and cut one end off. Strip back the plastic and expose the red and black wires. And then on each black and red wire strip back the plastic to expose the metal wires. Take your battery out and tape the red exposed wires to the positive side of the battery and the black wire to the negative side of the battery. Then being careful not to pull off the tape and wires plug the good end of the USB into a good USB port and let it charge for 30 mins. This will give you enough power to boot up and flash. Had to do this personally once on my OG ATRIX
I am just a teenager, don't trust myself doing that. Don't wanna fry myself doing that. Do you know how I can at minimum get it to turn on when in the computer usb port. All that happens is the notification light turns white.
If the battery is dead it won't turn on without getting a charge on the battery itself first. The only other way will be as posted earlier by Jim and having it plugged into a wall charger that I know of.
When I plug it into a wall charger, it does not charge. It plainly only gives it enough power to stay on, it acts as if instead of a charger, it just just a connection directly to a power source that is necessary to stay connected to to work.
Im at work tonight so I'm limited as to what I can do but tomorrow I can walk you thru fabbing up a USB cable if you want me to. Its really rather easy and the USB ports don't put out enough power to hurt you. Trust me I know LoL. But like you said if you don't feel comfortable doing this then I totally understand.
If we can't get your battery some juice then the only other thing I can see is ordering a spare battery charger just for the battery itself.

try..
1. plug it in. might have to plug it in and out then back in.
2. pull the battery then put it back in.
3. it might need a smack on the back to boot up.
my power button is dead, since august. it usually boots up when plygging in or giving a smack on its backside.
another method that works.
If your phone is powered off(not standby)
hold down volume up/down and plug in usb from computer. It will power up on its own and enter download mode.
Then pull the battery and immediately put back in and will boot up normal
I put a video tutorial up on how to turn on and use the Nexus One for daily use without a power button, hope it works for the Nexus S as well. It's a short clip and shows exactly what to do, it can be found: here
Hope it helps.

All you have to do is plug in the phone to an AC charger, and the phone should come on.
Sometimes, however, it will show the boot logo, then go to a screen showing you your battery percentage, and not actually boot. No problem. Just pull the battery and unplug. Replace the battery, and while holding the "x" button on your keyboard, plug the phone back in .

Im trying to explain everything to prevent unneeded questions
I have viewed several threads about this but absolutely none with an answer. My Samsung Infuse 4g with at&t (nonrooted) is in a bootloop. The cause of this was my every-other-day reboot. Once I turned it back on it goes to the samsung screen for about 5 secs, then goes black, then says samsung again and so on repeatedly. I pull the battery and as soon as it makes contact back with the phone it turns on by itself into the same Samsung screen over and over. When plugged into wall or computer it will show the charge screen where there is no battery life left, then it will flash and start up the charge screen again and so on just like the samsung screen. I cannot go into download mode (the buttons, at this point, do nothing. No response)
I have tried taking the battery out and plugging in usb cable to computer, then holding both volumes and putting battery in=charging loop
↑ with volume up=charging loop
↑↑ with volume down=charging loop
computer doesnt detect it, adb cant find it, cannot go into download mode, odin cant see it, heimdall cant see it, cant actually boot into anything, cant leave battery in or else phone will restart itself the entire time, and this was caused by my (already gbread) infuse 4g doing a regular reboot (aka power button, tap power off, after phone is confirmed off take battery out, battery back in, turn on)
Recommendations at this point? on a scale from 1=noob to 10=expert im a 7 on this type of thing. Ive always heard that as long as you can boot into a picture its only soft bricked but if i was right i wouldnt be here. Any and all help would be much appreciated. If you need me to post a video I would have NO problem doing that showing everything im doing.
oh, and by I have viewed several threads about this i meant that i have only been able to find 1 thread about it and 2 links that didnt work for me but might for you

You might have already tried this way, but I've always held down both volume buttons first before plugging in the USB cord - not the other way around. You can also try different cords, different USB ports and/or different computers.
Mine was doing this the other day and it turned out to be my SD card being flaky. Maybe try taking it out and booting?

Ive tried a hp touchpad cord, an atrix cord, and the original cord. I cant really do the button combo because as soon as the battery makes contact the phone turns on. thats why i had the usb cord in first to see if it worked. ive tried every usb port and 2 different laptops, the computer wont recognize it if the phone wont go past the samsung start up screen

>hold both volume buttons...NO NOT HOLD THE POWER BUTTON....

and bam should see the android dude shoveling in yellow triangle...
If you get no response from the usb without the battery, and inserting the battery indicates the battery needs charging - I'd suspect the phone's usb port. Especially after trying different cords & computers.

Hello.
I have the same problem... tried also everything now i gave it to cellphone shop, i hope you guys can give me answer before i am gonna waist $100
HELP?1
Help me please
I was in this state. There are two options I can think of. A JIG as mentioned previously or the Heimdall One-Click-Unbrick. The one-click unbrick did it for me and got me back to cmw and download mode, then i could flash to stock, root and flash up to ICS. It was really easy and I stopped sweating once it booted to cmw instantly after running it.

hello.
The problem is when i connect it to my computer its keep disconnecting and doing terreble noise, (windows noise) when you keep connecting and disconnecting USB cable
JIG DIDNT WORK, because the same problem.... maybe the chargging connect is broken? or has a corrosion?

Thanks ✟
Moving to Q&A
Sounds/Looks like a hardware issue...
Did it get any water damage in the past?
Hope you got warranty or still under warranty.
I am having exactly the same problem. My Infuse has never been rooted or unlocked (quite ironically, I was about to root it for the first time).
Boot loop when not plugged in, charge loop when plugged in. Absolutely no combination of buttons, inserting/removing the battery, and/or plugging/unplugging the USB has gotten it to do anything.
This has happened several times over the past few days. The first few times it sorted itself out in an hour or two. Today I couldn't get it to do anything at all.
I found several posts by people who have this problem, and it has never been conclusively solved from what I've seen. Finally one person said they fixed it by lightly smacking the phone with their hand. Lo and behold, it came on for about 5 minutes before looping again. So I smacked it again, and before it could re-loop, I factory reset it. A few hours went by and I was convinced that it was fixed.
A few minutes ago I had it plugged in to my computer via USB and was getting ready to SuperOneClick it. Then it went back into loop. I can't get it to come on this time. Again, no combination of buttons will send it into download mode. The computer can't see it. The battery is charged. The USB cable and port are fine. The software was reset earlier today. Does this mean that I have a hardware problem, or is there a software issue that could be fixable?
EDIT: So I decided to try hitting the power button, something that had never worked to this point, and the device came on. A couple minutes later it went back to boot loop. On a whim I tried download mode, which had stubbornly refused to work all day. Of course it immediately worked. Not really knowing what to try, since I'd already wiped user data, I wiped cache data and formatted the internal SD. Then I told it to reboot. Back to boot loop. A few minutes later, it came back on with the power button. Two minutes later, boot loop again. Then it restarted of its own accord. And now back to boot loop. I just don't even know anymore.
EDIT2: Just a thought... Something is weird with the power button. Whenever the phone is on and I hit power (briefly, not holding it down), it goes to the shutdown menu as though I'd held it down. A few seconds later, I'm always back in boot loop.
Infuse loop
I have found the problem. It is, in my case, the power button. I removed the case and crossed terminals with a paperclip. BAM. Booted up, and when I removed the paper clip.... back to boot loop at Samsung logo.
There is a place to send the phone. Ive see great reviews.

Seems like there has been a string of power button malfunctions going around lately. There are a few threads going on where people have had this issue. Sometimes its just the terminals needing to be cleaned or dust blown out.
