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 !!!
thankx again guys 4 all ur help!

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.

New Issue about camera!!

i noticed a strange problem after i did the following:
1- Configure Face lock for the device and it's working normally
2- connect the device to PC.
3- after using the device normally for about 5 min restart it while connecting to the pc.
i'm not able to unlock it using the face lock anymore as the Front camera isn't working gives black screen even after restart!!! the back one as well!!!
i made data factory reset (twice) and the camera is back to normal.
has anybody been there or tried this before??
this happened to me 2 times after doing the same above steps.
can somebody help

in which mode do you connect your phone to the PC? If its harddrive, the issue might be that the camera cannot access the phone's memory and will not allow you to take picture.

of course not harddrive!
it's only in 'charge only' mode
also if it was like you said, after restart it should be back to normal but it doesn't
and its not about taking a photo, its about the camera itself doesn't work gives me black screen only.

This is the most similar thread I've found to my problem.
I noticed today that my camera isn't working anymore. When I'm starting any camera app the screen is black for a while(some ui elements are still visible). After ~10 sec the screen is covered in multicolored stripes. (cant link image since I'm a new user :/ )
The last time I remember it working was when using front facing camera in skype.
I have tried a couple of other apps, restarted and factory reset the phone with no results.

[Q] Screen's gone fuzzy and weird - Solved

My Captivate Glide's screen does this whenever I turn it on:
I didn't drop it or get it wet, it just started doing this randomly.
I live in the UK and ordered the phone unlocked over eBay so I can't take it into an AT&T store, sadly.
Do you guys know if there's anything I could do myself or anything someone more experienced in repairing mobile phones could do to fix the screen?
This is bearing in mind that not many people over here have seen one of these phones though.
Any help would be massively appreciated. Thanks guys.

you was using still GB right? just flash ics via odin, with one click or with a tar file
This is UCLH2 without one click
http://androidromupdate.com/2012/09/...ota-stock-rom/
And here is the latest version with bug fixes (like keyboard light)
http://androidromupdate.com/2012/11/...ptivate-glide/
and there is for one click
http://www.androidauthority.com/captivate-glide-sgh-i927-att-android-4-0-4-ics-uclg9-leak-110365/
i think that only one click wipe your internal storage. but is the bes (in my opinion). try it, dont have anything to lose

No, I already updated it to ICS. Should I reinstall it? Will that fix the screen? How will I manage to do it with the screen all messed up?

if you can put in download mode, then you can. Its weird because i only see that problem with GB. Put in download mode and then reinstall

I just tried putting it into download mode but I get the exact same thing.

Thats weird, the problem is weird because it never happen to me in download mode, maybe you can try it without battery, or let the phone without battery a couple of hours, etc.
Dont Know what you cand o, because if you cant enter in download mode, you will be no able to flash ICS

Hrm... that purple splotch in the bottom left of the screen doesn't look so good... Almost appears as if it had been dropped on that corner at some point in the phone's history. I am tempted to say that is a hardware issue, though. Reminds me of when the flex cable for my laptop's display started shorting out many years ago. Might be repairable, but, might be a costly repair depending on what all needs to be replaced. I can't imagine replacing the software on it will do much, though, sorry to say. You could give it a shot, you can verify if your phone made it into download mode without the display by loading up odin and seeing if it detects under that, and then running the one click install (or any other since you'd have odin running anyway) but I wouldn't expect much.

If you're not getting the Samsung/Rogers logo screen, you're done. Either the screen is physically damaged, or the bootloader is corrupt. There's no saving that one, sadly.

yes, try what Artemis-kun say. put in download mode and connect, and see if odin detected. Or maybe just turn on the phone and wait a little, then try to call to your phone, if the phone ring or appears to be on, then is a hardware problem.
But try what Artemis-kun, maybe you have luck
PD: now i see better the image and it seems little different from what it happens to me. if you turn on, inmediatly happen that? or screen banish slowly?

AW: [Q] Screen's gone fuzzy and weird - need help please
There should be a cable, connecting the hardware to the display. Maybe it loosened, you should check out the video of a guy tearing his glide apart, hopefully youll find something to repair there.

Galaxy Nexus freeze after unlock **UNROOTED** troubleshooting

Alright, so here is what's going on.
I had my alarm go off earlier today, got up, unplugged my phone like normal. I swiped off the notifications I didn't care about like a tapatalk message etc. I noticed that Google Current's automatically updated. I'm sure that's no huge deal.
I locked the screen and went about my day. I tried to swipe to unlock, and the phone freezes and reboots. The phone is responsive until you unlock it, then it just freezes and reboots.
Tried safe mode once, and it worked fine. I then turned it off, and tried normally booting again, same freezing and rebooting. So I went to go back to safe mode, and now safe mode is doing the same thing, which means that a factory reset is now out of the question.
What the hell man.
Specs:
- Samsung Galaxy Nexus
- All stock apps except added Facebook and Tapatalk
- Jellybean 4.2.2 software I believe. I'd double check if I could.
- Still locked and unrooted
Any ideas on where to go from here? No warranty, so any ideas would help
It turns on, goes to lock screen. Then freezes when I try to get anywhere from that lock screen. Even on safe mode.
Then it will reboot automatically after about 30 seconds.
I should note I received a text in this time, and thought maybe just pulling the notification bar down and going straight to the text would work. The notification bar works, but when I hit the text, it froze the same way.
This must be some sort of self check or some Android process crashing. But I can't utilize safe mode to fix it.
Any ideas on what to do? I know there are threads with this problem, but this involves an unrooted phone, of which I have seen no threads, or threads with answers. I am not experienced with getting too far into Android, so just a direction to go, or something to try when I get home would be awesome. (At work currently)
The only options I have right now are the options upon booting with the volume down, which are Start - Restart bootloader - Recovery Mode and Turn off. In this screen, here is my info:
FASTBOOT MODE
PRODUCT NAME - tuna
VARIANT - maguro 16GB
HW VERSION - 9
BOOTLOADER VERSION - PRIMELA03
BASEBAND VERSION I9250UGLL1
CARRIER INFO - NONE
SERIAL NUMBER - xxxxxxx
SIGNING - production
LOCK STATE - LOCKED
In recovery mode, I see a dead android guy with a red triangle and an exclamation mark in it.
I realize you guys probably get a lot of dumb questions so I tried unloading all the information I could. My replies will be 5 minutes apart, as I'm new and I see that's a restriction on being here.
Thanks in advance

You can try unlock the bootloader (it'll erase your data so be careful) and then try flashing the oficial google image via fastboot and see if it solves it.
EDIT: in that screen of red triangle press up and power at the same time to show the options. There you can do a factory reset to see if it solves it. No need to unlock the bootloader that way.

Got it. It works now, but curious, is this a common occurrance? I have no idea what caused it, which worries me. But it seems to be working fine.
Wasn't worried about data loss, I haven't had the phone for too long yet. I plan on just installing the minimum apps. The point of me not unlocking it was to avoid issues, but I had more luck with unlocking it than leaving it locked.
That said, I wasn't aware you had to hold the vol up and power button to get to the options from the dead Android screen. That was an oversight on my part when I was looking up for data.
Words cannot explain how thankful I am, so thank you

No problem everything should work as intended now. What happened was a bit strange indeed. It it happens again with everything in stock then there is a possibility that it is faulty hardware and you should replace it. Maybe it was some configuration bug and nothing extreme

Fauly hardware can cause this issue? I baby this phone, has yet to be dropped (let's admit, it's inevitable), the only thing it's seen is three drops of water that fell off my sunroof onto it. I immediately grabbed my phone and wiped it off, but it was all on the screen, not in the speaker or anything.
Either way, I'll keep an eye on it. Thanks again

[Q] Black Screen... PLEASE Help!

If This has Already been Posted I'm Sorry, I couldn't Find anything that fit..
I have a Samsung Note 2 Unlocked on 4.1.2 stock. I have a recovery on it..
This is what is going on and I Really Could USE Some HELP..
I tried to download an App last week but it wouldn't download. Then Friday the App just started downloading. It was just a simple Pic App. Friday Night, My phone died, so I charged it about an hour or so and Tried to turn it on. When it comes up with the Samsung screen then All of a Sudden the word Samsung starts jumping up and down and gets lines through it. The phone boots on up but the screen Stay Black. The lights come on where the buttons are and it makes the sounds from my text messages and things like that.. It also makes the sound and vib when I Unlock the screen but Still can't see Anything.. I can put it into Download Mode and see the Screen Fine but when trying Recovery Mode or Anything like that then the screen goes back to moving with lines and looks like static y.
What can I do??
I've went through all the files on my phone and SD card though my computer and Removed that APP but it Still didn't help... I'm Not Sure but I was thinking I could use the Factory Image to redo it but I'm not sure how to go about it. Also Will I have to re unlock my phone and I would like to upgrade so do I Need to 1st put what was on my phone then upgrade from there or just use the new one??
THANK YOU for Any and All the Help..

I have now Tried to re load the Stock Software 4.1.2. It was Successful and after it rebooted then it did the same thing with the Samsung Note screen. Then it showed some lines and lights kind of like it was going to come up but Never did, Just went back to the BLACK Screen... PLEASE SOMEONE HELP! Is there a way to Wipe Clean and Start Fresh by using the Computer..
Thanks for Any Help...

All I can think of is use Odin to flash the latest factory Rom, and see if that fixes it.
