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.
I decided to install VooDoo lagfix on my new captivate when it still didn't have anything on it to minimize potential loss of information. I downloaded the lagfix, got it started, then the damn battery popped out when I got off my bed a few min into the mod. Immediately I felt like an idiot. Now, when I start my phone I get this sequence: ATT world phone screen, then a GALAXY S / GT-I9000 / SAMSUNG screen which it freezes on.
I have odin3 v1.7, but I'm unable to get it to Download Mode with any of the methods I've found (I don't know what I need for adb or what it is though...).
If I attempt to go go into download mode with Vol + & Power it shows a circle of radial lines, then it goes to a battery with the circle of radial lines (and I'm still holding both Vol + & power), then a black screen, then repeats what seems an indefinite amount of times. If I release the Power or Vol buttons it stays black for a couple seconds then it goes to the charging battery screen.
If I plug it in and turn it on with odin3 running, the phone stays on the frozen GALAXY S screen, odin3 recognizes it as COM6 but wont allow Start.
Any help would be great. My intuition says it has to be fixable if it's software.
Not sure if this will help, but earlier today I installed a theme on my phone that wasn't supported by my kernel by accident. The phone went to the AT&T World Phone screen then hit the Samsung Galaxy S screen and froze. I pulled the battery out to unfreeze the phone and then I put it back in after a few seconds and turned the phone on. I immediatly did the three button method and held it down so the phone did the AT&T World Phone/Samsung Galaxy S thing. I kept my fingers on them and the phone rebooted again (which is supposed to happen) and I kept the three buttons held down so again, it rebooted. After the second reboot I immediately took my fingers off the buttons when the AT&T World Phone screen popped up and I got into recovery. Now, this is a theme so it's totally different, but it's worth a shot and hopefully it works for you.
But if that doesn't work I still wouldn't worry as you most likely didn't brick your phone. If it was bricked it wouldn't be turning on at all and Odin is reading it at least so I'm sure with the right help if my method doesn't work, you can fix it.
Hopes this helps you man!
No power, just volume up and down plus in usb
Get a Jig. I was in the same boat. Worked like a charm.. You can make one (I did)
http://forum.xda-developers.com/showthread.php?t=841512
or you can buy a jig. Will surely work. Good luck
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...)
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?
adb reboot download
should get ya

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.
A friend of mine tried to root his S8+ from T-Mobile while following random instructions on the Internet and got his phone into this weird boot screen, which I must say I have never seen before.
Note: I have tried many times to enter to download mode by using the power button, bixy, vol- combination to no avail. When I turn the phone off and plug it in into the computer it gets recognized as QUSB_BULK.

I was wondering if any of you have had similar experiencies or perhaps even help me find a solution. Thank you in advance for your assistance.
This isn't anything out of the norm and has been covered more times to count. Get back into Download mode and finish the process.
Thank you for your answer and thank you for pointing out that I should have said that I've tried countless times to enter download mode by pressing vol- + power button and then power + vol- + bixby to no avail.
The only way to get the phone to boot into something is to press all buttons together while waiting around 10 seconds which, gets me to the screen in the picture.
Is there another way to enter download mode apart from using the regular bixy + vol - + power button combination?
hold down vol- and power only. when it resets, immediately keep trying bixby vol- and power. also if the phone is in a case take it out.
i think you have a fake s8+
It doesn't work, it gets detected as QUSB_BULK every time, only if I press all buttons does it give me a screen which is the one posted.
This is a genuine S8+ from T-mobile, I've made sure of it!
This happened to me
This is the worst, after giving up thinking my phone was bricked I just let it run out of battery. After it was dead i held volume down + power + bixby while plugging in a charger and to my suprise it went into download mode. I tried again and again to confirm it worked and it worked every time. So you just have to wait till the phones completely dead, and hold those 3 buttons while plugging it in to a charger.
Thank you for your answer, I did try that but it didn't work for me... no download mode, just that upload mode - unknown error...
I have the same issue plz help
Yup I've seen that same screen you're referring to on my S8+ Tmobile. It's tricky but you can make it work. Change the way you try to hold that combination of buttons. As previous answers mentioned, you have to be quick.
Here is what worked for me:
I plugged the phone into the computer, using the original USB cable.
Hold "PWR"+"BXB"+"VOLUP" until you see the phone's screen blacking out completely. Then IMMEDIATELY hold "PWR"+"VOLDN" and keep holding. That should put you back into Download Mode.
Again, it'a bit tricky so keep trying and checking your technique but you should eventually get it.
I've seen that issue before where no button combination gets you out the QUSB_BULK mode. I'm afraid it's a corrupted bootloader (aboot), which can only be fixed using a special "Dead-Boot" package, which uses a QComm low level loader (not download mode). You can search for it, but it's pretty hard to get since it's specifically written for each model. Here's a package available on a pay site https://combinefile.com/index.php?a=downloads&b=file&id=32731
