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?

Thanks tazfanatic. I tried the backup procedure and it didn't seem to work, and I think I actually have CWM 5.5. Is the procedure any different?

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.

Broken Screen NEED pictures

Alright guys I give up trying to think of ways on my own to fix this but a couple weeks ago I had my phone in my lap while I was in my car. Got out. Screen shattered, not touch responsive what so ever. My phone isnt rooted (stupid move on my part). It is stuck on a lock screen. Im not sure if USB debugging is on or not. When I plug it into my computer (mac or windows (8) ) nothing pops up so I am assuming its on charge mode... It is connected to wifi when I turn it on if that helps any?? and I am also pretty sure it is still somehow connected to the play store if that helps any?? I need these photos I have alot of once in a life time moments on this phone.... and yes I now have a G+ automatticly uploading from my new phone any advice would be greatly appreciated!
Thanks for your help and time,
Tim

Because of the protection, yoi cant pull the photos with screen broken

If you press vol up + pwr the phone will enter service mode and media content can be pulled out. But it says service center only. So i don't know if you need a special software for it.
Another way would be to install Lg onscren and use the program to browse the content.
But this works only on stock rom.

The onscreen wont connect, because phone rejecting any connections with screen locked.
And you cannot unlock it with screen broken lol
I had a similiar situation, and i had everything turned on (adb,mtp etc). Still nothing of this worked
Why you dont just replace your screen?
They will not wipe your phone, in my case they just replaced the screen in front of me and thats it.

Have you tryed with "on screeen phone" from LG

Yah I have tried the onscreen and hes right it wont work because its locked. And I have thought about replacing the screen. About how much does it usually cost and would it be cheaper to do it myself?? is it hard? sounds scary to be honest.

Have you tried Moborobo and use its file manager USB debugging must be on. It worked for me with a cracked screen and no touch and locked Optimus G.
I'm sure my USB debugging is on.
I've also ordered a OEM LG Optimus G E975 LCD Screen and Digitizer Assembly with Front Housing from etrade supply.
There are videos on YouTube on how to pull the phone apart.
Hope this helps.

Ok second question and I swear I am done I got all my pictures off and then deleted everything that was possible to delete in that program. I saw there is a backup/restore functions. If I can find the original system file that came on the phone (which I havent researched it yet but) could I use that restore function to whip everything clean and do like a "factory reset" in order to get all my information off it to resell it as broken??

I cant remember where I got the program from. I think i installed from some firmware update folders for some android devices.
And it auto starts when a I connect my phone to my PC. So it was only by chance that i tried it.
Regarding the backup/restore function i cant help you there. If you have another device try it on that.

Hi,
I'm having the same issue, except I did not manage to have debug mode enabled. Is there any way to pull files off the phone via "Download Mode" or am I just out of luck on this one?
Thanks

I apologize for that last post. It's completely stock, not unlocked or rooted. Running most current software and firmware from LG. WiFi is still enabled on the phone and I can ping it from my desktop, but I cannot get MTP or usb debugging to turn on since I can't get the touch screen to work.
Let me know if you need any more info.

I have this problem without USB debugging enabled when plugged in to pc i cannot accept to make it accessible from the pc since my screen is broken. Anything i can do to take off these very important pictures please help. im on stock rom no root no bluetooth on.

Screen does not respond to touch

All of the sudden the screen of my new Nexus 7 does not respond to touch.
I was looking to my emails, then stopped using the tablet for 10 mins and, when I tried to use it again, the lock screen did not recognize my swipe motion. I then tried to reboot it: pressed the power button, touched the Power Off option and nothing, also here it did not register my touch.
I was able to enter into recovery mode (using power and volume keys) and perform a factory reset but that did not solve the problem.
I am stuck at the lock screen and I cannot unlock it.
Any suggestion?
Thanks!

i think its just a 4.3 software bug. i love the tablet but the new update isn't very good IMO. google needs to get this right.

Since it has to be new I'd recommend just trading it in for another if a reboot or reset didn't fix it. I'd hate to see a fellow get stuck with an unreliable device. It could be many things though such as a bad digitizer or loose LCD ribbon flex cable or just a software glitch. To check the flex cable you would have to disassemble the unit which of course could potentially cause problems when trading it in. I dropped a tab one time though and it Jared my charge flex cable loose and just reinserting it fixed it. Good luck

Wait for Google to release official image then return to stock to see if it fixes it.

I have a feeling it is a software problem. It was perfectly working and few minutes after it was not. Nothing, hardware-wise happened in the middle.
Software-wise, I noticed, on the top of the screen, the notification that a keyboard update was installed. Could have it broken something?
I thought a factory reset would have handled that possible problem but it did not.

[Q] Samsung Ace II will not turn on

Hello, new here and I know nothing about rooting nor have I rooted my phone but after looking all over the net I have come here in hopes of finding some tech wizards that can help me.
The Problem:
Turned phone off and a few hours later I tried turning it back on but it only shows the screen with model number and Samsung under it. It shows for a few seconds then the screen goes black and keeps looping like this. I have not rooted or anything. Not dropped in water ( water square is pink though). Phone shows no water damage or corrosion after opening.
What have I done?
I tried booting in recovery and download mode but i have never done it before and I was not successful at getting any other screen besides the model number Samsung screen.
I have tried a different battery after spending some time at the mall (no on carries it any more as it is no longer made) different battery did nothing. Repair guys suggested it may be the button sticking and said hey could clean it for $25. Instead I went home searched the web and disassembled my phone. I cleaned the button areas on the inside of the case and the contact on the inside attached to the circuit board. I have reassembled and it still does the same thing.
After more research I found a video saying to actually remove the internal button from the circuit board to stop the loop (which will leave me with no power button) I have not tried this as I am not that bold (yet).
I am wondering if it is a software problem that can be fixed by using Odin and installing the stock firmware but I just have not found a proper guide that makes enough sense for me to actually try. I don't want to waste my time with something I have never done and make things worse.
I have downloaded Odin and firmware from sammobile but that is about as far as I can go without some hand holding....
Thanks for reading my story any help would be much appreciated.

Thanks for the reply. I have tried this many times and tried again after reading your reply. This should work fairly fast from what I understand right?
My phone is a virgin mobile phone (Canada) is it possible they have locked out recovery / download modes?
When I try to start in recovery nothing happens at all. Screen does not light, phone does not vibrate. Again I have never tried this until now so I don't know if the phone ever booted into these special modes when it was working.

Hi I have a samsung s2 t989 which has broken volume buttons and I can not give you hard reset your phone starts but no longer leaves the samsung logo I want to know if it's something a sal odinul reset put something there?

Without volume buttons, you can't get into recovery or download mode. You can with an app, if your rooted... But of you can't get into your system, that's out too.
You need to fix the buttons, or shop for a new phone.

Sorry, never taken a phone apart.
Look for any damage or loose parts. Clean the contacts or whatever and see.
Otherwise a service depot would be best.
