Hello,
I am having an issue with my S 3. It is not booting up as it should. The model is SGH-1747M.
I have tried the following and have had the following results:
1) The phone is non-responsive when attempting to power it on with the power button.
2) If I remove the battery, with the phone not plugged in, and then put the battery back in, the phone begins to power on by itself. It vibrates once and then loads to the Samsung screen and then goes off.
3) If I plug the phone in without the battery, the phone vibrates once and the red charging light comes on but then goes off after a couple seconds.
4) If I plug the phone in without the battery, and then insert the battery as soon as the red light comes on, the charging screen comes on but then the phone goes off after a couple seconds.
5) If I put the battery in with the phone unplugged and hold Volume Down, Power and the Home Button, the phone boots to the screen where you can push up on volume to flash new firmware. If I stay on this screen without pressing anything, the phone turns off after a couple seconds. If I push up on the power button, it goes to the screen with the green android man but then turns off after a couple seconds.
6) If I put the battery in with the phone unplugged and hole Volume Up, Power and Home and then release them on the Samsung screen, blue writing pops up in the top left corner (I couldn’t read quick enough what it says) while still on the Samsung screen and then it loads to a screen saying Samsung Galaxy S III and then the phone turns off.
These problems started when I attempted to connect my phone to my laptop to transfer songs over to it. I connected the phone and the battery was charging, but it wasn’t showing up as connected on my laptop. So, I turned the phone off to restart it but when I went to turn it back on, these issues started.
The phone was rooted and has been for the last 7 months without any changes to the firmware or updates to the firmware in that time period and has not encountered any problems prior. I’m not sure what firmware the phone was on prior to this.
If anyone could offer any assistance with this it would be greatly appreciated.
Thank you in advance.
Hi,
I'm no expert, but it looks like a faulty/stuck power button. It's normal for the phone not to completely boot up when it is powered off and then plugged in to USB. But it is not normal for the phone to reboot itself when in recovery or in Android. That's why I think the power switch might be the cause.
Problems with my Samsung Galaxy Tab S 8.4 SM-T705:
1st: October 2014
2 weeks after buying, my tablet's battery drained overnight from 45% to zero. Next morning, I turned my tab on after charging to find out that the Tab starts but without any Samsung GAlaxy Tab S logo or Samsung Logo and the Screen has turned green, rendering it difficult to read in auto brightness mode or low brightness mode.
I restarted the device 2-3times and the device started working normally. This was my 1st device restart. I never used to power off the device before.
In 1st 6months, this greenish display problem n logo problem occured 2-3times, and i ignored it, because, it used to get resolved by itself with restart and I had no service centre in and around 50km to my work place.
2nd: January 2014
My device all of a sudden stopped working.. actually hanged.. I managed to turn it off but failed to restart it.
Later I realised that the device has restarted, but the screen was not responding when the screen blinked for a moment with the opening of book cover.. and the back cover of device was warm..
Googling taught me the way to access recovery screen n I opened recovery mode with "power+vol down+home key" and pressing vol down in recovery screen to restart tab.. again the tab started working fine..
3rd: Lollipop update: May 2015
I did Lollipop update. The device was smooth to operate at first. But gradually, i noticed that unlocking the tab failed to light up the display everytime, just the soft keys lighted up. But one day, the device freezed with no response from touch screen. I was unable to switch off the device also.. I had to drain the battery by playing music using S voice to turn the device off. "power+vol down+home key" too was not working.
On googling, I learned to reset device with "power+vol up+vol down" keys pressed together. finally the device restarted, but the device used to hang occassionally.
Googling let me know that i need to factory reset device upon firmware update for normal functioning, which i didn't do after update. so, I backed up my device, uninstalled many apps to make the device run a bit smooth and did a factory reset.. Resetting didn't improve the situation much, but now, the device display failed to light up on a regular basis on unlocking most of the time..
Now the situation is that, the device turns on, finger print scanner works, all apps n everything working, but display remains black, and touch screen is not responding.. using sidesync, everything on Tab can be accessed via laptop.
Tricks tried:
1) Factory reset
2) power+ vol up+vol down
3) power+ vol up+home key
4) power+ vol down + home key
5) Power off using sidesync and then restart
Results: All failure. Everything works but the display never lights up normally..
Plzz help....:crying::crying:
Bump. I'm starting to have similar problems with my SM-T800 running 5.0.2. I open the cover and the device fails to turn on. I press the power button and the screen stays black but the notification bar turns on. I can shake the crap out of the device and the screen stays black but I can see the notification bar flicker. Driving me batty.
If i had any problems like you guys, I would just return it to the place i bought it, for a refund or replacement or even a repair, post it to the service centre if it`s too far to travel too.
You problems sound like battery and or loose connector inside your tablet, it happens frequently on Samsung tablet for the connectors to come loose, if the tablet is dropped or twisted, no outside damage might be seen.

Hello everybody,
2 days ago, my Google Pixel XL received the January patch and downloaded it. It installed the first step flawlessly, but the second phase took a lot of time (the progress bar was staying around 50% for at least 60 minutes). Since I was not watching my phone during the rest of the process, I cannot say precisely what happened, but as I wanted to look how far the progress bar is, the phone did not respond anymore.
here is a summary of the situation:
- it is the pixel XL with 128GB of memory directly bought on the Google store
- the battery was fully charged before the update began, an it was approximately around 85% as I looked at the progress bar for the last time
- the phone was not hot during or after the update
- the screen is now black and does not display anything (I have tried everything I thought about: it is definitely black and nothing happens anymore, even when plugged for charging, or when connected to a PC (the USB communication with the PC is not building up anymore))
- the phone react only when the power button is maintained pressed for several seconds: it vibrates briefly, but nothing more happens
- the phone was never rooted, there was no "unknown sources" app installed (I had Cerberus installed but have uninstalled it 2 days before the Android patch was installed), and the USB debugging is not activated
- I called the Google support and they immediately proposed to ship a replacement device (they did not ask me to do some tries)
I have tried to discharge the battery by maintaining the power-on button pressed during hours: the red led then turns on when the charger is plugged in, but the screen stays black.
If somebody has an idea of a test I could make, I would appreciate the held.
Thanks a lot in advance for your suggestions.
Best regards
Vincent
Have you held power and volume down for 14 seconds?

How long have you had it plugged in? It sounds like the battery is empty.
Try to leave it on the charger for a couple of hours.
If it does not boot by pressing the power button, you can try to boot bootloader by pressing volume down and power at the same time.
The battery has been fully charged, so I am pretty sure that it is not the battery (the phone has been plugged in for more than 12 hours to recharge it).
I have also tried every button combination that I know and that I found on the web: there is nothing else than a short vibration when the power button is pressed, but no reboot and nothing is displayed.

I would try pressing and holding the power and volume down buttons until you get the short vibration. Hopefully after vibration you will be in bootloader. Then connect to a PC and try and flash-all the factory image.

Thanks for your response. Unfortunately, after the vibrations, I do not get anything on the screen. In my previous phones, I was used to flash ROMs and so on. I never bricked a phone. But with the Google Pixel XL, I must admit that I do not have anymore ideas how to rescue it. I have tried the following:
- holding only the power button for several seconds --> short vibrations after several seconds, but nothing else
- holding the power button and the volume down button for several seconds --> short vibrations after several seconds, but nothing else
- holding the power button and the volume up button for several seconds --> short vibrations after several seconds, but nothing else
- holding the power button and the volume down + up buttons for several seconds --> short vibrations after several seconds, but nothing else
I have made these tries with the charger plugged in, plugged out, and removed at different instants. Nothing more than just the short vibrations.

Your screen may be black, but there is a small chance your still in the bootloader. I have read that other people have recovered from a black screen. I still think its worth a try to connect to a PC and see if the factory image flashes after holding power and volume down and after vibration. Those vibrations have meaning.
Thank you, I gave it a try: the PC does not even ask to install a driver, when the phone is connected. I made several tests, exactly as it is required to flash it, but there is no communication with the PC. :crying:

I thought there might be a small chance. At least you will get a new phone. Best of luck.
I hate to tell you this but I had the same issue with a 32 GB 5 inch pixel...It was dead...Everything you have said is what happened with mine.
What happened was the slot the phone was trying to boot into had no bootloader or it was a bad flash...Either way, the slot didn't have a bootloader on it when it tried to boot and that black screen is the result...Google sent me a new one and all was well and they will do the same for you.
This is why I don't trust OTA updates...I manually flash everything and I'm sure to flash the bootloader to both slots anytime I update my phone...Good way to keep this from happening again....Best of luck man
You keep saying several seconds. You gotta hold the power and volume down for a pretty long while. Just saying.
Probably a bad boot partition though..
Thank you very much for your kind support, guys.
Your explanations is very interesting. This means that the strategy implemented for the bootloader itself is not very safe. I would be interested in knowing how such a faulty flash can happen and what are the possible reasons behind. Is there a procedure that can increase the chances for a successful flash by doing some things before the OTA update is allowed to be installed?

Believe me, I pressed the button for a very long while also (hours) by blocking the button in such a was that the phone boots up until the battery is discharged. So also such an extreme tray was made. The only consequence was the red light flashing.
Iam having similar(exactly) situation as stated by OP. Phone dead, only short vibration, no boot loader, no dshub qualcomm either detected while plugging USB to pc. Charging still ok.
update: now phone can be detected as Qualcomm HS-USB QDLoader 9008 in Device Manager.

Phone is in Qualcomm Emergency Download mode. What happened? Also a bad OTA flash?
You only have two options:
Press power button for ~ 30 seconds to get out of EDL. If it's completly bricked then RMA. You're under warranty yeah?!

RMA is your only option so
I was getting a notice on boot that said "Your device is corrupted and cannot be trusted," so I held down the power and volume down buttons to get it to fastboot mode. However, I couldn't get it to be recognized in fastboot on my laptop. At one point I selected "reboot bootloader" and the phone promptly shut off, black screen and completely unresponsive.
From that point on, I can't get it to do anything. I've tried holding power + volume down for 20 seconds and then plugging it in (as noted in another thread) as well as taking it apart and disconnecting the battery to see if that would reset it somehow. No dice.
Any other suggestions before I give up? Thanks very much in advance...

my device is for the most part of the time in qualcomm mode, but I managed to have access to the phone 3 days ago, installing apps & stuff, worked perfectly well until I had
the bad idea to try to charge it through the charger instead of charging it through my computer...
how I've done it?
I used the power reboot technic :
1) pressing the power button for 1 minute
2) doing nothing for some seconds
3) pressing the power button again for 1 minute
4) connecting the phone to the charger, the red light flashed
5) the battery icon appeared soon after
6) waiting for complete charge, phone rebooting
it worked once, so I suppose it can work again. fingers crossed.
