s5 has black screen, lcds lights up on boot then goes black
the touchscreen is responsive after boot. I can hear sound when pressing the screen
does anyone have any suggestions to fix this?
I tried some fixes I found, held power 1min unplugged battery 5min, not working
bang power button a few times - not working
updated firmware and rom - not working
the lcd comes on for a seconds but turns off. the phone fully powers up and i can access by PC
Are you on a custom recovery? You should do a full wipe and Odin the factory rom from a powered off state first.

Also try booting up without the sd and sim cards installed.

Hey everyone, for some reason my S3 decided to take its last breath (hopefully not) today.. I had flashed Mastamoon's CM12 build for my Straight Talk S3 (SCH-S968C) today and got all successful messages as it was flashing but when I restarted it my screen did not want to come on for some reason. I have left it on the charger for the past 8 hours and there is no LED lit up to show that it is charging, the screen will still not come on or anything. I have tried to put it into download mode, recovery, and safe mode to no avail.. Connected it to my laptop to try and use ODIN to go back to factory defaults: no luck. Tried Kies and the Emergency Recovery: still no luck. Does anyone know of a potential fix or atleast a way that i can get the screen to turn itself on so i can attempt at ODIN again?

(For ****s and giggles I also pulled the battery and held down the power button to drain the power remaining in the phone and that has not done anything either when i reinserted the battery) :crying:
Edit: Sorry forgot a couple things. When I connect it to my laptop, my laptop will ding at me saying that it is connected. but it will not show up in my computer or disk management. It also went through the initial driver setup and still wouldnt show up.
I know that this is the Verizon S3 forum, but for this phone only the verizon roms have been working..
Take out the battery for like 20 sec hold down power and volume down until another screen pops up then press volume up
Or plug it in your laptop hold the buttons I told u until ding let off buttons and really quick press and hold them again

I just went on a trip to China and had my phone turned on airplane mode for the entire trip. On the third week I took my phone out of the charger to turn on in the morning and the only thing that turned on was a flashing blue light. It flashes from light blue to dark blue. I read that it is frozen, however, I tried everything that they recommended to try, different combinations of buttons and such. Verizon said they will replace the phone but I want the pictures from my trip in China off of it. I don't know what else to try. I called 1-800-SAMSUNG and they said they could do nothing for me. If I send it to them they will wipe the phone of any information. I went to Best Buy as well and they could not get in the phone. Please tell me if you have any ideas!!!!

What firmware are you on? So, you can't even turn it off?

I am not sure which firmware. I know there was an update during the time I was out of the country but I don't think my phone was updated. I can't turn it off. I just can turn it on, it goes to the blue blinking light and black screen and then the battery eventually dies and the blue light goes off until it is charged.

You do know that to enter maintenance mode, you have to hold the key combination for several seconds, don't you?

Another question. After it completely dies (completely), try charging it to 100%. Don't try to turn it on after that, though. Try to enter download mode. Volume down-power-home buttun. Hold them down, don't let them up. See if the option of download mode comes up.

I have made it to the maintenance screen with the normal reboot and a few other options but when I chose those the screen goes back to black. I have made it to the download mode as well but after I wait for it to download the screen also goes black.

Doesn't matter about the screen. Does odin see your phone? Have you ever used odin and do you have the Samsung USB drivers installed on your computer? Have you tried Smart Switch?
Edit: smart switch might wipe SD card. The "Home" .tar files are supposed to leave the SD card intact.
Both odin and smartswitch can be located here.

If you can do a factory reset from the menu, I believe it leaves the emulated SD card intact which is where your pictures are. Research it first of course but I would definitely try that before you ODIN.
Hi,
Hope you guys can help.
I've had my Nexus 5 phone for 16 months now - generally worked great. Occasionally it dies and wont power up, but tends to be fine once you leave it charged for 10 minutes and give it a go a few times.
However, now, it wont boot up at all. It has a mind of its own of turning on and off every few seconds, and then just staying on the Google logo before switching off again.
Very occasionally it gets to the 4 circles but again shut offs after a few seconds.
I've read a few threads that suggest pressing Vol button and power on button. I've tried that and get to the android robot screen, but it switches off like 1 second after, so im unable to select any options.
Any ideas very welcome?
When I have connected to a charger, it constantly boots up and switches off the google logo after couple of seconds all by itself.
but if not connected to a charger, then it remains off unless I press power button or give it a little knock.
Thanks a lot
I had the same problem and what I found is that it is a power button that is stuck. What I did to get the phone back on is to continuous press the power button until the phone fully finishes booting. After that it should be OK, if not a good smack to s table can also help, no joke. I set my volume button to power on screen and use an on screen button to turn of because its hit or miss with the power button for me. Thought about getting it fixed but have no time.

I have this problem to. I sent it to service, but since its rooted, the wont repair it if I don't pay. It's baught from dustin.no, not Google Store
They say the motherbord is broken because of overload, because the rooting..... I have ordered a new powerbutton from Ebay, and will try to replace it if this solution doesn't work.
Can this be true, that the motherboard got broken because a rooted the phone?? I have never did anything else that rooting......
Hello.
I installed (via apk) a new Google Play Services version on my N5, the Google Play Services kept crashing every 10 seconds. I tried to reboot it to bootloader by holding down all 3 physical buttons but I let go of one to soon. The device turned on immediately and I immediately repress the button I had released just after the device turned on. Now my N5 is off and won't turn on. Please help!
Does it not even reboot into bootloader, from where you can restart? It might jog it into action.
Presumably it has enough battery? Have you tried charging for a while just to be sure and then trying to restart?
Clutching at straws here, but I know how frustrating no answers at all can be.

In fact I've just booted my N5 into bootloader from off, using only the power and volume down. No 3 buttons needed. Give it a go.
Press power off for 8-10 seconds till it reboots. Then all u need to do is hold the power button down and your BL will be up

Why would you do that for op lmao
My S7 was on the charger last night and worked fine. When I woke up, the screen is black, and the only sign of activity is a flashing blue LED. I've tried all the hardware keys to reset the phone, and nothing changes. Plugging the phone into my computer, no device shows up at all.
Any ideas to try and fix? This phone was stock, and not modded in any way.

I've had this issue when my phone was in a deep sleep state and wasn't able to wakup, but a simple reboot fixed it... So I'm hoping you have the same issue

If nothing else works like pressing power button home button and volume down and then waiting for your phone to vibrate twice, if you don't see anything you have damaged the display... If it works then good news screen isn't damaged

Worst case scenario is the systemui was modified and now keeps force closing, you'd have to reflash the stock rom through Odin. I found a wipe data factory reset in recoery doesn't work.
thanks for the reply, unfortunately no matter what i do, the device will not reset. the display remains blank, and the blue light remains flashing. I am familiar with using Odin, and my PC does not recognize that anything is being plugged into the USB ports. Right now I have the phone in the freezer trying to drain the battery to see if it will start up upon being recharged.

Try connecting the MicroUSB > USB adapter that came with the phone to a power hungry USB device such as a USB fan, see if it is working enough to power the fan or whatever you connect, which will drain the battery quickly
