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 dont know if this is a brick but I cant get any button combos i have tried to work this is a friends phone I am trying to fix. THis post is a copy and pase of another I found on another forup but it pretty much sums up my issue. I cant do the KDZ thing because so far I havent gotten into recovery and I saw another sugestion on how to restore the default rom and settings but it requires having the phone booting properly.
For the last several hours, I've been trying to just get my phone to turn on past the white LG logo against a black screen. I don't know how to get the phone into any kind of recovery mode or emergency mode. I've looked at tutorials on similar phones, none of the suggestions worked. Among those suggestions were:
- Hold the down volume + home button while holding the power button
- Hold the up volume + return button while holding the power button
- Hold the up volume + home button while holding the power button
I've had to take the battery out of my phone and put it back in numerous times. I've tried removing the SD card and replacing the battery. I had my phone rooted and was attempting to install custom recovery via Android Terminal. The last thing I remember was typing "su" and then at the # typing "sh /sdcard/rf.sh". The phone rebooted to the LG and I've been trying to recover ever since.
The phone isn't even recognized by my computer when connected via USB, although when the phone is connected to the computer via USB it will turn on from off position -- ostensibly I think this means it is charging?
I've read at least 12 different fixes on 12 different forums, I've googled, searched, asked for help, and my head is about to explode. There is no example that tells me anything definitive such as:
a) If my phone is for sure bricked
b) How to tell if it is for sure bricked
c) What I can do short of returning the phone
Can anyone help me to figure out a way to at least get my phone to boot up?
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...)
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!
Please help me! I own a galaxy s6 (international model, official, not rooted) which is stuck in a boot loop from hell. The led is white (not the usual "boot-up blue") and won't change colour or even turn off. It was the last straw a few hours ago when it randomly restarted, got stuck halfway through the Samsung logo and started making the loudest noise I've ever heard it produce. It was NOT a vibration. Ever since then, it has just been stuck and keeps restarting. When it does get past the "Samsung Galaxy S6" screen it just says 'no command' with the android lying on its back. I'm at a complete and utter loss. It's actually done this a few times this week, but I've always been able to at least boot it into safe mode and uninstall snapchat - which I think is the cause of all this. I can't power off the device, and even when the battery drains completely, the same 'no command' screen appears as soon as it's plugged in. I can't boot it in recovery mode as I can't get it to switch off. I think it may be battery related or even motherboard related. I can't even seem to bypass the 'no command screen. It's just sitting on my floor, charging, overheating and looking all smug. Frankly, I'm pretty damn close to hurling it out of my window.
Also, does anyone know WHY the led is sometimes white or yellow during a boot loop on newer Samsung Phones?
Put the phone in download mode by holding Power + Home + Volume Down buttons. Plug in to Odin and Flash Official Firmware or use SmartSwitch

Thanks but I've tried this several times. The device seems to be completely unresponsive to all commands except a force restart (power key and volume down). I can't put it in download mode or even power it off
have u tried using smart switch emergency firmware recovery? power key and volume down should force it to power down, than enter download mode vol down + home + power key.

if you are not be able to take your phone to download mode then repair center is the only solution.
