i did not install anything new, last thing i remember doing is just taking a picture. now i have a working phone with a black screen how do i fix this?

good luck

If on boot after pulling battery it is still black and download mode shows nothing, and you have tried Odin (it works but you see nothing still) I am afraid you need to head to the Sprint store.

try to odin to ec05 stock ... leave your phone again for a while and see when you get your screen back if you can get to download mode and odin that stock rom ... this will allow you to see if it is something up with a rom you're running.
if it does it then, you'll be at stock so when you go to the sprint store; it won't be an issue.

I agree Odin back to stock is your best option and if that dosn't work you probaly stuck with a black screen!

Yes, if you got it to come on once by leaving it you should be able to do it again and Odin before making any calls.

I had no choice but to take it to the sprint store
they fixed it !!!

Hey, I know this is an old post but I have an old Epic I'd like to see if I can trade into for credit towards a Galaxy S III but I'm having the exact same problem as described here:
Softkeys light up, screen hepatic feedback "buzz" can be felt, can swipe to unlock and answer a call based on blind-memory of what to swipe but other than that, the screen is completely black. Not black as in lit up but devoid of any other color except black, but gone dark.
If it weren't for the softkeys being lit, I would assume the screen were either broken or disconnected from the motherboard somehow. There are no cracks in the screen. Phone has seen better days for sure but the screen is intact and all functions were working perfectly before it simply...blipped off in front of my eyes.
I've tried doing as you did: charging it for 3+ hours and seeing if that worked at least temporarily. No go.
Assuming our two phones were experiencing exactly the same issue, can you tell me when you had it repaired, if the issue was a hardware or software issue? If hardware, did they have to replace the screen? or was it merely not connected properly somewhere?
If it was a software issue, how did they repair it? I'm assuming I can, in fact, get the phone into download mode, but without a visible screen, I can't boot off of a zip file or see if any of my actions are successful. Can't be sure I cleared the caches properly before I proceed, etc.
Phone was last running toadlife's CleanGB prior to the FC09 update and I'm pretty sure, prior to EL30 (I can't remember but I'm pretty sure it was).
Again, I know this is old but any feedback would be appreciated.

Hm, so you're saying download mode or recovery mode open up but with a black screen? But it still reads touches? My guess is it's hardware, a loose connection to the screen.

Yeeeeah, good luck towards funding your S3 purchase.

I'm having this issue have my phone was dropped yesterday, so I'm quite sure it's a hardware issue.
I have two questions: can somebody be so kind as to give me the button sequence for how to make a nandroid of my phone? I have CWM 5.0.2.7 without the 'one confirm' option. That would be awesome. Also, is anyone familiar with taking the phone apart and perhaps how to fix this issue?

Indeed. I'm running CM9 beta 2, and I'm pretty sure it came with 5.5. However Taz, I believe if you boot into recovery from ROM Manger or the power menu, it still takes you into your previous recovery version (such as 5.0.2.7). Or vice versa. I don't remember. To my knowledge, this is has something to with the switch to MTD, and the devs just have reroute that command.
But regardless, I'm not getting a new backup on my SD card, so I'm pretty sure I'm on 5.5. Kenny, do you know if there's a different button sequence for 5.5?

5.5 is the same. I would remove the battery to make sure it is powered off. Put the battery back in, hold camera, volume down and power in that order (making sure power is last) for 5 seconds. wait 20 seconds to make sure it booted into CWM 5.5. Then volume down 4 times then camera twice. Depending on how many apps you got I would wait 30 minutes before pulling the sd card to check in clockworkmod\backup directory for a new file with current date code.

Please help, Samsung Galaxy S II T989 keeps rebooting

About a month ago my phone randomly started rebooting out of nowhere. It was in my pocket and rebooted a few times and stayed on for a while. It kept getting worse and worse to the point where it would not even boot up. I updated the phone using Kies and it worked for a few hours, but then it went back to doing the same thing. The warranty already expired and I replaced the screen on the summer, so it doesn't have the sticker behind the battery.
Today I installed the original software using Odin and it turned on and booted and seemed to work fine for around 2 minutes, but then it restarted and kept rebooting again. I have also noticed that the menu at the beggining when you press Vol + and - and the power button is not the same one as factory. Please help me out here with any possible solutions and let me know if you need more details. Thanks.

What does the recovery say when you press the volume keys and power button? Have you rooted it since you Odin'd back to stock?
Sounds similar to others who have had the power button go bad on them, search the general section and you can read up on that issue. Since you were able to replace the screen it shouldn't be a problem for you to replace the button actuator too!

Yeah I researched and tested the phone and the power button seems to be the issue. When I put the battery in the phone, it automatically turns on, so I guess it needs to be replaced. I will look into replacing it. Thanks. If you know how to do it, please help me out.

I'm having this issue too but i cleaned the power button with a straw(Capri sun)..i just made it pointy and cleaned around....been working fine for a whole day. I avoid pressing it so i use volume to wake phone up. I hope it helps, i was all crazy about my phone like 2 days ago because i didn't know what was the problem. If anything PM me.

Quite a few members here have used that service so yes it's safe. I wasn't happy with the amount of time it took, but it's a good service otherwise.

[Q] My TMO S3 (T-999) will not turn on.

I didn't have luck finding an answer to this on the forums so I figured I'd make a new post. I have been running a version (not sure which) of Liquid Smooth for a few months. Yesterday, I noticed my phone was on a boot loop. It would vibrate, show the Samsung Galaxy S3 screen and then turn off. I pulled the battery and memory card and tried again. It still wouldn't come on. I pulled the battery and then rebooted to recovery mode. I went there to wipe and reboot. When I tried to do that it said something like, "what you are looking for can't be found". I pulled the battery again but this time when I tried to turn it back on it did nothing. I have no vibrations, I have nothing on my screen. I'm not sure what could have happened because I haven't made a change to my phone for quite some time. Any ideas?

You don't have a spare battery do you? If not, you should see if you can find someone you know that has one. It could be that you battery just went bad.

I tried all of this but did not have any luck. The phone doesn't do anything. It doesn't make any sense how it can just stop working out of nowhere like this. Wouldn't it mess up immediately after I rooted/added a custom ROM if I did something wrong rather than a few months later? I'm afraid that the phone may be done for. : (

I hate to say it, but usually when something like this happens it's most likely to be hardware related. If you don't have access to a spare, go to a T-Mobile store and ask to borrow a battery to see if it'll power up with a known good one. Batteries usually don't just die like that, but it can happen.
So you don't get a short vibe or anything out of it? What about when you hold the power button for about 10seconds? If you remove the battery and plug it in, do you get an led lit up? How about with the battery in?
If the battery turns out to be good, you could attempt the debrick method by KAsp3rd stickies in development. I don't see why it would be a brick, but at this point I'd try anything available just to be positive.
If you have insurance on it, it may be time to consider using it.
Sorry to hear this is happening to you man. These S3's are starting to get a little old though, and no matter how careful we are, they do suffer more abuse than any other electronics we may use. I'm seeing more and more posts like yours recently, I'm sorry to say.
Keep us updated on it, and good luck with it!

Verizon G3 won't power up

Hey there. Hoping someone can help me out here. Long time lurker, and I used the search button, but similar threads did not help me out...
I was out and about yesterday, phone was fully charged, and working just fine. I had used my phone and place it back into my pocket. A couple hours later, I pull the phone out to check the time, and it won't turn on. I assumed the phone had shut itself off like it has in the past randomly. So I press and held the power button. Nothing comes on at all. Screen does not turn on, there is no boot sequence, no LED light, NOTHING. I proceeded to remove the battery and replace it, still no power. I press and held the power and volume down, NOTHING. I read on here about removing the battery and holding the power button for 15 seconds to clear any power in the phone, put the battery back in and on the stock charger for 15 minutes, then trying to power the phone up. NOTHING. I took the phone to Verizon, and they were no help, they could not power the phone up either. We even tried a different battery. I am not awaiting a refurbished phone... only problem is I have loads of pictures saved to the phone (I don't use an SD card).
I am creating this to reach out and see if any of you know of a method I can try to get this phone to begin working?
At the very least, I would like to pull the pictures and files I have downloaded onto the phone... and I am really hoping that there is a way! (I have my serious doubts since the phone doesn't power up... but still I want to ask).
Any help would be GREATLY appreciated!
And thanks in advance for anything that may be provided!

Two options I would try:
-leave the phone plugged in a whole night/day (original charger)
-try a spare battery (if you didn't already)
-clean all contacts

Definitely try leaving it plugged in for a while. Also, have you tried hooking it up to your PC? Does the computer recognize the device?

Hi all, stumbled upon this thread while google searching. I'm also having similar problem as op. one moment the phone was working, next moment cant power it on no matter what buttons I press.
To answer this question, at least for me, when I hook it up to my PC it just shows QHSUSB_BULK, which according to my research means its been hard bricked.
I'm probably going to send it in for repairs

Wow, that's terrible. What module? I know messaging with the build prop can are you up, but I've been tinkering with various Xposed mods for a while and never had an issue. And I'd think if it was a bad module you'd have seen the issue immediately, not after a random text message. That's just bizarre.

Sleep of death issues

I have had sleep of death issues infrequently with the Note 3 in the past. I have been having to do a battery pull every month or so. Of late , the issue seems to have become worse. I have had three battery pulls in the last 2 weeks. It has happened both while the phone was charging and also while not charging. I'm thinking long of doing a factory reset.
Any thoughts or ideas before I go do the factory reset?
Edit- I am on the stock rom.

A lot of times this will be caused by an app not working correctly. You can test this theory by booting your phone to "Safe Mode" and let it stay in that mode for a while. Before booting to "Safe Mode" check your running apps and make a note of them. If you do this and it resolves the issue, you'll need to track down the app that's causing it. Remove the latest apps that you've installed one by one until you find the culprit.
To boot "Safe Mode" turn off the phone normally. Now hold the power button to boot the phone, and while holding it, continue tapping the left menu key continuously until you get to the Lock screen. You should now be in "Safe Mode"
If you do this and the problem continues, try clearing the cache partition with recovery.
To boot recovery, turn off the phone normally. Now hold volume up, home, and power together until you see the Samsung logo. It will tell you it's booting to recovery in the upper left hand corner.
I hope this helps.

Thanks for the response. I went ahead and did a factory reset. I'll try your method if I run into issues again.

I am still not sure what sleep of death means, I see people complaining that the display doesnt turn on but the soft keys illuminate. In My case nothing works it looks like a phone with dead battery and to make it work I have to pull the battery. Today I had another weird issue. I sent a message using FB and the screen froze I was able to turn of the display using power button but unable to restart it. Again another battery pull to fix it. So can some one please explain what exactly is a sleep of death.

A factory reset is always the quickest way to resolve issues. I just learn how to do this stuff so I can help out when people have problems. And if you're like me at all, completely setting things back up is very annoying, especially when you do as much testing and flashing the number of ROM's that I do.

A lot of times the "sleep of death" is caused by what's known as a kernel panic. It's when the kernel isn't functioning right and won't let certain aspects of the Android OS function properly, that being the part that tells the hardware keys what to do, or something that affects things in other parts of the OS. But kernel panics can be caused by a rouge app like I explained, or even a bad OTA update. It's just like a computer will have a brain fart at random times for unexplained reasons.

Thanks for explaining all The info. would a Kernel Panic cause the hardware buttons also not to respond. I have hardware buttons also failing to respond and that leads me to beleive it is a HW issue.
Thanks!

Yes a kernel panic can cause anything not to respond. The OS determines what to do when a hard or soft key is pressed, even the power button. With the kernel ultimately controlling all of that, it could be the problem. It also very well could be an actual hardware issue though. The only way to tell for sure is do a full wipe and factory reset. And if that doesn't work, use Odin to flash a complete stock image. If either of those procedures fixes the problem, then it was a software issue, whether that be an app or the OS itself. I will be back on here in just a little bit if you need any guidance in doing any of that.
