Unable to get Captivate in to Download mode - Captivate General

Hey guys, I was flashing back to the stock ROM when it got interrupted. The phone displays the phone-!-computer icon when it's turned on. I've had this happen before several times but each time I've been able to get back into download mode by removing the battery, sim and memory card, reinsert the battery, hold the volume buttons, and then plug in the USB. This time it will not go into download mode. I've searched the forums and tried all the variations but nothing will get it in to download mode. The only think i haven't tried is the soldering the resistor to the USB connector trick. Does anyone have any other ideas? I would really appreciate any help.

Make sure you have Odin3 One Click [Stock] downloaded.
Try pulling your battery, hold down your power button for 10-15 seconds to drain flea power so your RAM will totally clear in case anything is still on it.
Open Odin3 One Click
Put your battery back into your phone
Hold down the up and down volume buttons on your phone, and simultaneously plug your phone into your computer.
Your phone should go into download mode which will show a yellow triangle with the android digging, and you should see your phone show in a com port in Odin. At this point, just click start and hopefully the Stock Rom will flash successfully. You can find how to flash to stock and the link to Odin3 one click in the captivate bible post in the android development section.

Hey, thanks for taking the time to reply. I still get the phone-!-computer icon. It just seems like the download mode isn't enabled or something. I've seen this screen before but i've been able to get into the download mode without too much trouble.

How long have you left the battery out? Try leaving it out for at least 5 minutes before trying again. If that doesn't work, build a jig.

Hey, i'll give the 5 minutes a shot but it sounds like i need to make an emergency trip to Fry's on my way home from the airport. Thanks for the info!

Hey, just wanted to post a follow up... the jig cable DID work! It was a tense couple of moments after i plugged it in but it worked! I was able to reflash with odin and the phone is back up and running! Thanks a lot to the people who helped out!

[Q] Cannot get download mode - HELP

I was trying to get 2.2 on my captivate. It got hung and after about an hour, I powered down phone (battery out).
I'm now getting [phone... (!).. COMPUTER] picture
Trying to get back to stock ROM 2.1, but I cannot get device in download mode
I had to use adb to get in download mode originally.
Is it possible I got a phone that doesn't go into download mode based on button combinations? If so, what do I do?
Unplug your phone from USB
Pull battery
Close Odin
Open Odin
Put in battery
Hold both volume buttons (NO POWER) and plug in USB
Hopefully this gets you into download mode
Still Fail
I've been trying that, but without open/close of Odin.
Still failed when I added that step.
get to that screen again: hold volume up/down and power at the same time.
When the screen goes black, then release power button but keep holding down volume up/down

Yes, and remember to keep the volume buttons pressed in while plugging in the USB... I always hold them in until the droid/caution sign comes up.

Try the methods prescribed. There are several minor variations but you may have a phone that doesn't do three button recovery. In order to tell, we need some history on your phone. What is the RF Cal date? Were you able to three button into download before? Do you know if it was one of the ones that had the three button problem?
autocorrelation,
I tried that with the usb cable plugged in and without it plugged in.
Still no good.
joeybear23,
I've been trying that all afternoon. Probably about 50 times.
ianwood,
How do I get the RF Cal date? I don't see it under the battery where the S/N is located. I tried to do 3 button recovery to put phone into download mode when trying to install 2.2, but it wouldn't work. I had to use "adb reboot download".
I've never tried it before today. The only issue I've had was that it could NEVER connect to AT&T server to check for an update.
can you get it into recovery mode?
no recovery
No. It won't go into recovery mode either.
The only thing it WILL do is respond to all 3 buttons being pressed by the black screen flash after about 8 seconds.
If you keep holding all 3 buttons will it flash again after the initial black screen? Try releasing the power button and keeping holding vol up/down after the second black screen.
If I keep holding all 3 buttons, it just keeps flashing.
Also tried to let it flash twice (and even more) and releasing power right when it goes to black 2nd (or 3rd) time. Also tried releasing power half way through black screen, and right before black screen re-appears and also just as the screen powers back up. None of them work.
I ran into this yesterday and about freaked out. Don't panic - apparently one of the guys had this happen to them a lot. Take a deep breath, have ODIN open, plug your USB cable in, hold the volume buttons down at the same time, press and hold the power button till you see the phone to computer, and let go. You should get to the download screen again. Good luck; sucks when something like that happens and you don't know what's going on.
I know this wont help much, but I have one of the no 3 button phones, and after 20 minutes of trying all these methods, it did go into d-load mode. Unfortunately, I don't know exactly which combo I used since my brain went into overload when I finally saw the triangle appear. There is hope though, and please PLEASE post which one works for you(I'm afraid to mess with mine until I find a foolproof method)
I had a phone that wouldnt respond to ANY 3 button combo I tried. I bricked it (sorta on purpose) to the phone-!-computer screen and went and replaced the phone at AT&T (under the 30 day deal).
It didnt initially work with the 3-button but after the JH7 OTA DL mode and recovery mode work perfectly now. Also, GPS has been completely spot on when testing on my motorcycle with the phone in my backpack running my tracks.
If you are under the 30-day return policy, bring it in and come up with a good reason as to why they should give you a new phone. If not, then you're sorta SOL....

This method just saved my butt!!!
I have never had trouble getting into recovery or download mode until today when I did a dumb thing. The phone would lock at the ATT screen when trying to power on and if the phone was off and I plugged it in to charge it would freeze and the circle logo that comes up before the green charging battery does.
Every method of getting into download or recovery failed up till now.
Thanks Zilch!!!
Hey guys gonna move this to Q&A.
I had this problem a few days ago after updating to 2.2. I tried every single button/usb/battery combo and nothing worked. FORTUNATELY I was within 30 days of purchasing it (I guess there's a silver lining when diving right into "hacking"), and I brought it to the store with the box and receipt and just told them it gave me an error when turning it on (played dumb) and they swapped it out without even testing. If you're over the 30 days then I think you're pretty much SOL... gotta pay for a replacement.
bricked
I declared it to be bricked and took it back to the store. I have only had it 2 weeks, so I basically pulled the same move of playing dumb and they gave me another one without any problem.
I'm wanting to try to see if I can put it in recovery mode and/or download mode with the buttons without even attaching it to anything, but now I'm paranoid about bricking it.

Buddy, we need you to remember I'm in the exact position, no combo works and I bricked it after trying to load 2.2
Going into recovery or download will not brick it, its only everything after that point that might get you bricked.

[Q] bricked?

Rooted my phone, installed cwm and modded 3e recovery, everything seemd to work sofar, clickd to restet into boot mode? i think that was the next step and now im staring at the samsung screen for i cant tell you howlong. Usb dosnt recognize device cant reset it into boot by holding power and volume. Any ideas? sorry if this was covored somewhere but I searchd in the forum and im not reading countless threads in the infused post to see if they had maybe been covored, iv been poking around for an hour now im asking for help.
Start by pulling the battery and follow the instructions found here.
EDIT: If you need any help, I will be around all night.
Don't need to pull battery, I've been able to enter ODIN mode as follows:
Hold down VolUp+VolDn
Hold down power button for a while (10-15 sec)
Phone should reboot, release power button, keep holding VolUp+VolDn
You should be in downloader mode now.
Also some of the instructions for entering downloader mode were a bit funky, they said something like:
Pull battery
Insert USB cable
Hold VolUp+VolDn and then insert battery
In my case the following works:
Insert battery, do NOT touch Power
Hold VolUp+VolDn
While still holding them, insert the USB cable
You should wind up in downloader mode
Pretty much as long as you're able to enter downloader mode you're not bricked. I've been frozen at the SAMSUNG screen MANY times (kernel hackers get used to it...)

[Q] Samsung Galaxy Captivate (Rogers) not booting

This is my first post on the boards, so I apologize in advance.
This phone belongs to a friend of mine, they had it rooted and then they reset it to factory default, and it stopped working. That's when it was given to me.
Specs:
Samsung Galaxy Captivate (Rogers)
SGH-I896
When I got the device, it could be turned on and would say "SGH-i1987" and "19000i" or something. After a short time an "S" would appear and glow until the screen went idle. It would never boot up.
After a lot of trial and error, I eventually got it into download mode by holding VOLUME DOWN and clicking the POWER button.
Once on, I tried flashing using a One Click Odin from this site. It seemed to be installing through Odin and eventually the device booted up an "AT&T" logo then rebooted, and kept doing so over and over.
After 5 or so minutes, I hit the power button and Odin said 1 Successful/1 Failure ( i believe) and so I unplugged the device.
Now when I turn it on it keeps loading the AT&T logo and then rebooting, or if I connect the USB it shows the grey battery, then reboots.
Here I have tried everything. I tried VOLUME UP + VOLUME DOWN, VOLUME UP + VOLUME DOWN + POWER, VOLUME DOWN + POWER, USB, no usb, I tried 10 times doing each. I could never get a different result.
I bought 3x100k resistors and tried linking them, ran it over a meter and say that it had 300k resistance. I tried making contact to the microUSB slot but after a few hours it still hadn't gone into download mode. I stripped a microUSB plug but I had to junk it, the contacts weren't helpful. I've since ordered a USB jig but would like to fix the phone before that comes in, if possible.
Is there any other way to fix it other then the jig, is the jig going to help? I have a microSD card, can I use that to enable the buttons or flash something helpful onto the device? I don't have much experience with this but I've read several forum posts on the subject so far. Also, if I get it into download mode, what is my best course of action to get a simple WORKING OS loaded.
Thanks a lot for any help you can offer me!

[Q] Trying to root, cant get into download mode

Im following this here:
http://www.techzek.com/how-to-root-samsung-galaxy-s-blaze-4g-sgh-t769-smartphone/
But the power, vol up and down get it to show the yellow "warning" thing that im supposed to see, but it goes away after like half a second so I cant get into it. What else can I do?
how to get to download mode.
As you press the volume +/- and power button , simultaneously plug the micro usb cable into your phone (this cable should already be attached to your pc). This should do the trick.
Happy rooting.
The instructions in the first post are wrong, and should be updated. You have to have the cable plugged in. In the video for example, he has the phone plugged in the entire time. You're not required to have three hands in order to get it done.
I've had no luck with any of the variations on this method either.
Turn your phone off, hold both volume buttons and with your usb plugged into the computer take the other end and plug it into your phone while continuously holding the volume buttons. It will boot into the caution screen and than you press up to get into download mode.

If none of the above still don't work try this
1. Turn off phone
2. Remove battery
3. Remove sim card
4. Remove SD card
5. Plug in USB from computer
6. Hold volume up + volume down
7. While still holding the volumes insert battery
8. Should now be in download mode

Thank you both for the replies. I've tried both methods several times without success. I'm tired now so I'll quit for the night. I'll try again tomorrow a few more times. If I can't get it to work I'll take it as a sign that I'm not meant to root this phone. I must have tried 30 times today; it gets old.
Update:
I've tried this ten or fifteen more times. I'm finding that the yellow warning message, whatever it is, doesn't appear at all, ever, unless the USB cable is not connected when I put the battery in. If the USB is connected, I get the gray battery icon every time, no matter what else I do.
If I do connect the USB, with the battery out, I immediately feel the device vibrating every second or so, as if reboooting.
I tried removing the SIM and SD cards again. This had no effect.
It's very strange. In that video the entire process looks about as easy as doing a simple battery pull. It's just not working for me. Is it possible that Samsung made some of these phones "root-proof"?
Worst case scenario you will have to buy a Samsung jig.

I had to do it a few times myself.... It did not catch for me the first 3-4 times...
Then it worked. Make sure you are holding down all 3 buttons down tight.

I think I've tried it at least 50 times now, with variations, and it's just not happening. I freely admit my ineptness, but holding down buttons is something even I can manage.
By "three buttons", I take it you mean two. I don't have separate volume up/down buttons on my Blaze; just a single rocker button. That's what you mean, right?
I did get as far as the warning screen, but from that screen there is no option for pressing up to go into download mode, so it seems that my warning screen is different from others'.
I guess the next thing is to research "Samsung jig" and figure out whether this is something I can possibly do.
I went through the same thing, I too thought I had to purchase a jig but the method I posted thanks to another member saved me, try again with a modification to step 6
1. Turn off phone
2. Remove battery
3. Remove sim card
4. Remove SD card
5. Plug in USB from computer
6. Hold volume up + volume down + power buttons
7. While still holding the volumes insert battery
8. Should now be in download mode

Thank you. I just tried it a couple of times, without success. I have to go out now, but I'll give it another few tries later.
If I have to get a jig, should the Samsung Galaxy S be compatible? I'd think so, but I don't know for sure.
This is a slight variation of what everyone is suggesting...I was also getting vibrations when trying other methods.
Turn off phone
Unplug battery
hold volume rocker, make sure you're holding down both up and down
Insert battery
Hold power button until the warning comes up...only takes a few seconds
I said three buttons, because it seemed (at least to me) that you need to hold sides of the volume button down at the same time. It does not seem to be just a up/down button.

Thanks for this suggestion, but it also didn't work.
This method, like some of the others, takes me into what I think is Recovery Mode. I'm not sure, because I don't really know what I'm doing. The message that flashes on the screen isn't really a warning. Doing it this way, i.e., releasing the power button but not the volume button after the phone starts, takes me to a screen that says,
Android system recovery <3e>
at the top. Then there are some options: reboot system now, apply update from sdcard, wipe data/factory reset, wipe cache partititon. I can use the volume button to select an option, and the "OK Key", whatever that is, to select.
Near the bottom of the screen, in yellow, is the text that I couldn't read before:
-- Verifying internal MMC block...
checksum confirmation -> check(0)
Not need checksum confirmation
already executed!!...
# MANUAL MODE #
And that's it. In the background of this screen, grayed out, there's a white triangle with a yellow exclamation mark in it and a little green android.
Is there a way to get from this screen to Download Mode?

I guess it might if I could get ADB to work. So far, no luck; but that's a whole different problem. There are pages upon pages of posts here from people having difficulties getting ADB to work, so it'll take days or weeks to sift through all that and figure out what I'm doing wrong.
I thought the actual rooting process would be fairly simple, and it would only get complicated when trying to install custom ROMS and that sort of thing, which I'm not trying to do. It appears that I was wrong. I think I just don't have the knowledge to do this.

Make sure you have Kies Air turned on when you try to connect. You can use USB or wireless mode then. I tried and without Kies, it would not connect.

So I should have debugging mode and Kies Air turned on, and then ADB should be able to find the Blaze? I'll try it tomorrow.
Thank you.

black screen after downloading custom os from odin due to update

Okay, here is the problem. I have looked around, and this thread seems to be close to what I initially ran into.
http://forum.xda-developers.com/showthread.php?t=2199042
What seemed to cause this was some sort of update verizon was telling me to download, and I kept deferring it until I accidently hit yes. After hitting yes and the update going through, the phone booted to "System software not authorized by Verizon Wireless has been found on your phone.”, which would force me to restart.
If I used odin's button patterns, I would come across the mentioned route in the thread.
But the route I went (because I assumed it would work) is download what was prompted as a "custom os" as opposed to denying it and (I'm assumed based off the thread just posted) starting the phone up. After an hour long car ride, leaving the phone alone and apparently "downloading" the custom os, my phone turned off.
Now what I am facing is only a red led when charging (which is normal when charging while off), but when using any odin button pattern, my phone simply vibrates and nothing more. Nothing on the screen, even when pressing the power button itself. It just stays pitch black. I have no clue what has happened. Any possible suggestions? I tried with battery out, charger in as well as battery in, charger out, and charger in, battery in.
If you plug the phone into your computer and power it on/attempt to enter Odin, does your PC recognize it?

Actually, plugging it into my computer just keeps making it vibrate as if it is starting to power on. I can't even get into odin or even a screen coming up for that matter.
Hey thanks for the help! I figured it out. I guess the battery was incredibly depleted from leaving it in download mode in odin. I charged it up and after a few hours, the power came on. I followed the guide in the thread I posted and it worked like a charm. Sorry about the confusion and I greatly appreciate the help. Thank you!
