My Galaxy S5 won't start up... (black screen)

Hi everybody
I have a problem with my Galaxy S5 (no custom rom, official)
I normally used my phone, I locked it. But, after about 10 mins I tried to unlock my phone, but nothing happens
I tried to reboot, nothing happens. I tried take out and put the battery - nothing happens. So I searched on Google and tried some keys combinations, but nothing happens. My phone has about 80% battery. I tried to charge it in the charger, but nothing is happening (black screen, no notiffication light). Also I tried to put off my SIM and SD Card, but nothing happens
Do you have some skills in it? Can you help me?

Few days ago, I faced the same problem..
http://forum.xda-developers.com/showthread.php?t=2853472
Then I'd to take it to the Samsumg store.. And they return it back in 2 days and said me it was a software problem..

I wanted to do a recovery reset, but i can't boot my phone anymore, also the Kies doesn't see anything, so. Did you really think that is a software problem? Because my phone won't vibrate at boot. So maybe it can be a hardware prob :/
EDIT: Phone started blinking red light... (nottiffication), I tried to charge it, but nothing...

Mate as mentioned early, same problem I faced..
It'll be better, if you return it to Samsung customer care..

You seem to be saying that the problem occurred unexpectedly. So presumably this isn't subsequent to a flash error, newly installed app or a trauma (dropping the phone, etc).
First ensure that your battery is charged, plug in the phone to a charger as well and try turning it on. If at all possible, borrow a battery from a friend's S5 or go to a store and borrow a battery for 30 seconds to confirm that the battery isn't the issue.
If the problem persists, then remove the cable and battery. Then put the battery back into the phone and press and continue to hold in this order, the volume down key, then menu key, then power key. Hold all three until the screen powers up (about 5 seconds). If this doesn't work.. the most likely problem is a damaged power key - try pressing hard or "wiggling" it to see if that makes a difference.
If you still can't start the phone, then see if a local cellular repair shop has a "jtag jig" that you can borrow. Or you can buy one on Ebay for a few dollars. When this jig is plugged into the USB socket, the phone should automatically restart.
If all of the above fails (which is unlikely), you would seem to have a hardware problem or unknown origin. Which would be very unusual. If your phone is under warranty, make a claim. Otherwise get an estimate to repair it.

If I hold all 4 buttons at the same time and connect the phone to PC, PC recognises the phone for a few seconds. Well, maybe not recognises, I cant see it, but it plays the same sound as if connected flash drive to pc. However, everytime it disconnects within a few seconds...

I´m in the same case, but I was flashing the Galaxy S5 with the four files ROM and the pit file using Odin3.09. All the process ended well, but after rebooting there apeared one Screen sayin something like "Some files at this phone are encripted and there can´t be modified......." so I did a manual reboot and take off USB cable and from this moment the phone don´t do anything but giving a sound when I plug USB to computer cable and I can see new COM --> Qualcomm HS-USB QDLoader 9008, and there repeat a loop.
I´m still looking for a solution, but it gives me that there is time to change phone.

Possible Fix
This thread is old but idk if this was ever solved, so in case anyone else ever has an issue like this. My Gf is still rocking this phone so i've had a little experience with it. The phone wont turn on or charge. I got it to work by sticking a flat head screw driver and prying it fairly hard against the bottom of the battery (the side closest to the charge port) and forcing the battery harder against the metal contacts. While pushing the battery I turn on the phone and it starts right up and continues to run even after letting the pressure off. I've noticed this happens every few times i take the battery out, but this method has never failed for me turning the phone back on. Hope someone finds this helpful.

weird, youd think that bending the tabs out to force contact with the battery better would do the same trick fwif

S5 Strange USB/Power Issues

The other morning I woke up and my phone would not turn on after being on the charger overnight on the night stand.
I removed the battery, power drained the device and still the device would not post.
So I grabbed my spare battery and tried that, still no post.
I plugged in my device and noticed the charging light was not coming on, so i tried a different adapter and yet again no change.
I disassembled the phone and swapped out the USB flex cable with a new one, still no change.
So I plugged the device into my computer and I received a battery gray battery image that flashes away almost immediately.
I unplugged the phone held the power button down and plugged the phone back in. I received the Samsung writing with the model number but the device just goes back to the grey battery and flash away,
I attempted to boot the device to recovery mode but it just loops back to the grey battery,
I had then decided to try download mode with odin and restore the stock ROM. I can get the device into download mode but no computer recognizes the device in device manager or odin.
I have removed and re-installed the battery while in download mode and any computer will still not recognize the device.
I noticed one strange thing. If i remove the USB cable from the phone while it is plugged in the phone powers off and will not turn on until it is plugged into a power source.
It is almost as if the phone does not recognize that the battery is even plugged in!
If anyone has any ideas or could possibly point me in the right direction that would be greatly appreciated!
Thanks guys in advanced if anyone can offer any information on this issue!
Also, the phone is out of warranty!

OPT took a blow to its back, now wont turn on w/o USB & Boot Loops when USB plugged

OPT took a blow to its back, now wont turn on w/o USB & Boot Loops when USB plugged
FML ... ok so my OnePlus Two (A2001) slipped out of my hand while I was using it and the area right under the camera took a hit (not too hard) to the side of a nearby table (Battery was at around 50% last time I checked). Now the bloody thing wont respond, UNLESS i have it plugged in.
While it is plugged in, It either boot loops, with the boot screen being off center (the Word Android is on the bottom left of the screen and the OnePlus logo is on the Center-Left of the Screen, OR it boot loops with the screen perfectly justified when +V and Power is pressed. I had the newest official oxygen 2.2.1 installed on it. At this point I can only get it into fastboot mode using +V and Power. When plugged in and left on it's own, it boot loops with occasional "Low Battery" (with charging light on) but then it reboots again (disabling charging light an charging)
I've had the original OnePlus usb drivers installed on my PC before but plugging it in does nothing. Ive tried the Qualicomm Driver + MSM8994 method (http://forum.xda-developers.com/oneplus-2/general/oneplus-solution-hard-bricked-device-t3183449) with no avail. Installing the Drivers manually the OnePlus Two still shows up as "Unknown USB Device (Device Descriptor Request Failed)"
I've also taken it apart to see if there's anything loose/broken. I dont see anything wrong with it. Ive also pryed the battery from the back and detached the battery connector from the motherboard. Then plugged it back in, but it still does everything described above.
Fastboot commands to not work as it just looks for device. Fastboot Continue does not work.
Im running out of ideas..... =( Anyone have any new ones?

Seems like the OnePlus Two doesn't respond well to impact. Mine slid off my desk a few times onto a wood floor and now won't respond at all.

Mi A1 dead, LED blinks on charger, how to revive?

Hi! Similar problems have been posted on the forum before, but none of the solutions worked for me.
Stock Mi A1 with vanilla Oreo (latest official patch), everything stock & vanilla, no hacking, no rooting, no modifications etc whatsoever. All apps installed through google store, nothing fancy.
In short: put my phone into airplane mode about a week ago (battery at 90%), then a few hours into the flight the phone blacked out. Won't react to power button, power+volume up, power+volume down, all buttons, no buttons, any combination of buttons for any length of time. Phone was in my pocket, no physical impact or anything, just "died".
There are 2 signs of life:
- If i plug it to charge the notification LED blinks about 1 / sec
- If I connect it to a computer, it recognizes it as Qualcomm 9008 blabla device.
What I have tried so far and didn't work:
- All imaginable button combinations: no reaction
- Fully charging phone: doesn't help
- Letting battery deplete: doesn't help
- Disassembled the phone, disconnected the battery, put it in charger, reconnected the battery: this fixed the issue for some, didn't work for me.
I GUESS that since the computer recognizes it I could try to "flash" it or whatever, although 1) there are a lot of negative posts about it 2) I have no idea how to do it (which exact ROM, using which exact tool, etc).
I wouldn't mind not losing the data on the phone though, if that is an option: I was about to back up my photos on the flight, but it died before I could have done it.
There is no official Xiaomi support / service where I live, bought the phone while visiting a country which sold it.
Any suggestions?

Small update.
- adb doesn't see the device.
- Miflash sees the device, but dies at "ping via firehose" stage.
-A1 low level backup tool doesn't see the device.
After 2 weeks of googling I have found around 50 forum threads around The Internet with similar issues, but no solution as of yet. Sounds promising!

I had this problem 2 hours ago and fixed with the Disconnect battery, connect charger, reconnect battery (while charger is still connected just to clarify). you tried this fix like this? reconnecting battery while charger is still connected?

Maybe try getting a different battery and connect it, and/or maybe let the battery discharge itself.

Thanks for the replies fellas. I have tried this before. Now I have tried this again just to be sure. Did it multiple times. Disconnect battery, connect charger, reconnect battery. It doesn't alter the phone's state in any way. Doesn't react to buttons, flashes led on charger, shows up as qualcomm 9008 device on PC, but doesn't let me flash anything. Sad.

Qualcomm 9008 is sigh of faulty emmc chip. Bad soldering i guess. Take the device to the service center. My 1 cent op. Regards

Its very simple the solution. The problem is the cable. Try to change the cable, charging the phone and turn it on. I my case works

Have you had any progress? I'm having similar issues with my mi mix 2s.

The answer is to replace the battery. I have two dead batteries for my Mi A1. Both batteries were left in the drawer for several months and upon connecting them to my Mi A1 they showed the dreaded blinking light. After trying to fix this for a day I gave up. I disconnected the battery, the phone booted up right away. Bought a new battery and everything is working again. Hope this helps!

I too had numerous kind of hard bricks with my previous smartphones.
Here are the links that will save your life:

Try the ones that you think fit the most.

I had the same issue just today
removed the battery connector and connected it back without touch any other component
phones working fine now

its bricked and get into edl mode just try to flash with MiFlash tool i have faced this problem some time ago when i flashed an ota with twrp recovery then my phone went dead and when i connect it to pc led blinks and phone recognise in ports as "diagnostic port 9008d" something like that then i install the drivers and flash stock pie rom with MiFlash tool but after successful flashing phone wont boot but after pressing power button for 10 to 15 second phone starts. i have unlocked bootloader so it works for me but i'm not sure it works on locked device try it or use QFIL flash tool from QPST

This happened to me but all i did was charge the phone the whole time.

My Xiaomi A1 had the same issue, I think I have tried all available solution but unfortunately mine still dead, and when I connect the charger it blink.
I guess the ultimate solution is to throw it to a recycle bin.

Phone won't power on after removing usbc cable from desktop

Last night I had my phone connected to my computer to charger it per my normal routine before going to bed. I removed the USBC cable and the phone's screen instantly went black. Would not power on with holding the power button, power button and Volume + button together. None of the tricks I knew to try would work.
I laid down for the night and plugged it into the original charger and cable from OP, and the phone vibrated, showed the bootloader unlocked message, then back to black screen, never showed the boot animation. Intrigued, I then was able to get into the fast boot screen, I got excited and thought maybe by some chance there was a software/kernel issue and I could push the image from my desktop. So I unplugged the power cable and as soon as I did the phone instantly powered off.
Now prior to connecting the phone to the computer, the phone was at roughly 35% battery, so there was no way at any point that the battery was dead.
I left the phone connected to the oem charger and cable overnight, and upon waking up today the phone will still not turn on. I tried holding power and volume + for at least a minute and no signs of life.
I'm really at a loss here, I've had the phone less than 3 weeks, it's never been dropped or exposed to water.
I opened up a ticket for repair from OP but now I'm concerned that the phone is rooted and has TWRP, if they'll deny repair, even if it appears to be a hardware issue not software?
Are there any other tricks I can try?

Well as an update, I now know why I've seen many people say OP has horrible customer support. It took longer than it should have, but the repair facility says that replacing the mainboard fixed the problem. And sure enough my phone is charging and working as expected. Already updated, bootloader unlocked, twrp installed and magisk. Life is good. ?
