[!] SGS3 Screen off, boots up, no recov

The TL;DR is - Running ROM fine. Phone boots up but screen does not turn on. Does not seem to boot into recovery/download mode. adb is attached aka works.
Phone was sitting on desk, untouched and not charging. Now the phone screen does not come on, but hardware keys light up and notifications come on. I then charged the phone for several hours. Hard reset with a battery pull, let it sit for 10 mins, try to reboot. The phone vibrates once, and 30 seconds later notifications come in, hardware lights come on, and led blinks. So the phone is booting fully, but no screen on.
If I try either of the recovery or download combinations, the same normal boot up happens. So I cannot seem to get into recov/download normally. Odin does not recognize the phone. Windows OS recognizes the internal and external storage as normal. "adb devices" returns nothing.
Is there anything you think may solve my screen-off predicament? .... Worst case its a hardware problem Other than that, I am friggin stuck here. Your assistance and suggestions are greatly appreciated!

Had a similar issue when a flashing went bad. My charger was plugged in and for some reason it just kept looping like you mentioned. No combination worked.
I disconnected charger and pulled battery. Waited a few seconds and did the recovery combination. That did the trick. Hope it helps

I am open to suggestions. Plan on opening and operating, as I suspect it's a hardware issue. Worst case, any have experience with replacements?
(Oye, now I'm reviving the OG Droid Incredible ...)

Take it into a pitch black room and look closely, does the backlight try to turn on? I had a very similar problem where my backlight just died, I could see the faint outline of my home screen (like my brightness was on -50% lol) and everything worked but the screen. Ended up being a hardware problem.

Thanks for the suggestion. I cannot see even the faintest of light, just pitch black screen.
It's peculiar though --- the hardware buttons are not vibrating. As if it's not recognizing any input other than the Power Button. And thus, maybe why its not recognizing the volume rocker to get into recovery.

Bump: adb now works and recognizes my device. Open to suggestions!!!
edit: Tried adb reboot recovery ... phone turned off, vibrated, then received no input whatsoever -- however still made the connection noise when plugging into USB. Only solution was a hard reset.

[Q] xperia z3 not respondig

hello,
I had left my phone to charge at night, then this morning it was not responding. Power button was not waking up the phone. Then i forced to reset by power and volume buttons. Vibrated 3 times and completely shut off. Now it is not opening.
I already tried, reset button in sim cards slot. It is not working also. Please help me.

Did you try connecting it to PC Suite or FLashtool? Check that once and also try charging another hour and then force reset the phone. Also I think there is a reset button somewhere under the sim card slot. Try that one too.

Hold volume up and press power. Wait for beep three times. Give it a few seconds and then press power alone, should boot.

Thanks guys, i tried both but still i have sudden death. reset button and power+volume buttons not working. Also flashtool could'nt find my device.

Thats not good, any led when plugged in?

I had a similar instance after flashing unofficial cm12. Phone was cooling down from taking a run through an obvious cpu bug that really killed my battery. I shut it off to cool down with 20 precent still left in the battery. And the phone started to act this way when I went to power it on. No led power indicator or anything even with usb connected. My computer did respond to the usb being connected as if a device was there though. I waited about 10 minutes with the phone in front of some cool air and then did the volume up power button reset which worked then. Still quite a scary incident.

Red flashing but cant turn on??

Hi, I have a Sony Experia Z3. Great phone Was loving it. However I woke up this morning To a frozen screen. The screen then went blank and I now can't seem to charge it or turn it on. I have tried all kinds of resets but nothing seems to work any ideas??
Please??

try this first -
a. plug your charger into a wall socket
b. connect your phone & leave it for a few minutes
c. hold the power button and the volume button down together for at least 1 minute
d. expect to see a red LED/no charge indicator
e. release both buttons
f. push volume up
g. expect to see an empty battery graphic onscreen
h. now press the power button and it should charge normally

Also try connecting via the magnetic charge port. That usually fixes mine when it won't turn on

Try a few hours charging (maybe a battery issue) and try turning it on or just exchange if that fails. A similar issue on my HTC One X was due to a motherboard failure, eventually it would not turn on at all and had to get mobo replaced.

Power,Volume and camera buttons have all stopped working... and now the phone is off

The title is pretty self explanatory. Noticed when i woke up that neither the power, volume or the camera buttons work. They still clicked when pushed but no function beyond that. The phone its self still worked before i pressed the yellow reset button next to the sim card slot. when i pressed the yellow reset button the phone vibrated and turned off, never to come back on. When i plug it into a charger it still has the LED light except its off so i cant just press the power button to turn it back on. When plugged into the computer, then computer recognises that a device has been plugged in (makes the dun-duh! sound) but the phone is not recognised by either the PC companion or Sony EMMA. Same deal with pulling it into a mac. The Sony mac companion program pops up automatically , it says it does not have any device connected, despite it popping up when i plug my phone in...Ive put adb on my computer and tried adb reboot but again it does not recognise the phone while its off. Is there anything i can do to fix this phone or at least turn it back on? I've spent enough on getting this phone prepared as it is so a DIY fix would be great.any help at all would be much appreciated, thanks

I too am having issues while restarting my z3 after switching power key does not works.
It boots only when I connect it too my pc (still dead) and then press the yellow button(try the yellow button before connecting the pc too),but all the hardware keys works perfectly except the power which is just functinal.

No luck unfortunately. When i plug it into the computer the Sony logo pops up and goes to the charging screen. When i press the yellow button just after plugging it in it just restarts and does the same thing. Thanks anyway

That's exactly what happened to my phone last time,managed to get it started after some random trials ( it started using the normal power key after removing it from pc & letting it rest for some time)
Keep me posted if u manage to solve it.

Will do, I've gotten in contact with the sellers and they are happy to inspect the phone for warranty claims to see if I've done anything to it to trigger the breakage, so ill be sending it off tomorrow . You may not be able to answer this but i might as well ask, I got a whole screen replacement for the phone a few months ago as i had dropped it and the screen had smashed etc. The screen replacement all went well. Do you think the re sellers will know/care that the screen has been replaced? Will it impact upon my warranty claim? I don't plan on telling them I've gotten the screen replaced but I'm just worried they'll find out and say my warranty has been voided.

I replaced my phone's speaker from 3rd party,right after that I am having problem to restart the device.
I think Your warranty is probably gone.
Try to flash Ftf file,i didn't cause I don't wanna loose my root.(changing between roms help a bit)

when you open the phone and remove the battery, you can see like some flat wires. those connect all your buttons, screen, loudspeaker and other things to the motherboard. I'd say that the problem is in this flat wires if the buttons do not work. It can be changed but don't try it if you do not have some practical skill since the z3 is not really an easy phone to repair, it's all glued >.<
ps.
this is what i'm talking about, to be clear: http://www.ebay.it/itm/FLAT-FLEX-TA...008493?hash=item2c9efe04ad:g:4QkAAOSwyQtVt5MY

Samsung S8+ suddenly died

hey,
all the sudden, my S8+ died but I'm not sure if it's bricked or the screen is dead. Please chip in your ideas.
Everything was fine and the screen got black, the phone was still working but the display didn't have anything on it. Top LED was OK.
I tried to restart the device from my memory thinking that it's a system bug and did it.
The phone didn't wake up after that, or maybe it did but I cannot see the screen.
Now, when I hold down the power and vol - key the phone vibrates but no LED or display
if I only hold the power key nothing happens, no led or vibrations.
the phone used to vibrate randomly when untouched with a blinking blue LED. I'm not sure if it still does.
my screen has a crack on top, what I'm thinking is that water got in and did stuff
I need to access my google authorization app, and that is the only reason why I want it to be repaired. But, if it's going to be formatted during the repair work, it just doesn't worth it anymore.

Hi there,
That happened to me too exactly the way it happened with you. I just had to change the display with digitizer that i bought online and now everything is working fine.
