Galaxy S5 not powering up after the "Samsung Galaxy s5" screen appears - Galaxy S 5 Q&A, Help & Troubleshooting

My perfectly working Galaxy S5 was put for charging at night and the phone wouldn't turn on in the morning. I tried restarting it and at times the "Samsung Galaxy S5 - powered by Android" flashes for a second or so and then the phone dies again.
I tried rebooting it, unplugged/replugged the battery, removed SIM and SD Card and tried to start the phone but nothing happens. On charging the phone, the screen does come up to show that the phone is being charged and as of now it is 100% but still won't power up.
I must add that the phone has had its share of falls during the 2 year usage and there is a small discoloration / crack like effect on the top left hand corner of the screen which however cannot be felt by hand by rolling my finger on the screen.
Samsung guys claim it a screen problem that needs to be replaced however an independent repairer is confident that screen is OK and it has something to do with some other hardware of the phone. He even removed the battery and connected a multi meter to the point on the phone which connects to the battery, tried starting the phone and the meter would show some current getting drawn and then come back to zero. He claims phone is not able to draw current from the battery.
Any clues what could be the problem and how to rectify it. I have loads of data I don't want to lose on the phone.

Can you boot into recovery? Have you tried flashing a new firmware on the phone?

Phone isn't responding at all. No matter what I do, at the most the Samsung screen flashes for like 30 seconds and then the phone dies again.
On connecting with a computer the computer begins to recognise the phone and starts installing drivers for the same however it never completes the job.
So not sure how to flash a new firmware if the phone isn't responding at all.

Bumping the thread.

Another reason for this behavior is that the battery has no charge. Battery can be damage and no have charge at all
I would in this order
do you have another S5 available?
exchange batteries and see behavior
do not have another S5 available?
try to charge with a universal wall charger.
or it seems you have a tester. Make sure your battery have charge

Checked battery too but that doesn't seem to have a problem. Tried with other batteries also.
A local repair shop told me there's a problem with the boot IC.
My follow up question is can I replace the mother board with another Galaxy S5 motherboard? Are all the motherboards of Galaxy S5 compatible with each other?

I'd be careful when changing the motherboard. You *DO* need to find a compatible board...In other words which ever variant you have should be the variant you look for to source the donor board.
Also, you say you have data you want to recover? Swapping out the motherboard will remove every possibility of recovering that data; as all the flash storage is contained on the motherboard.

All the information you need is on the sticker underneath the battery.

Interesting piece of information.
I took the phone out almost after 8-9 months today. Tried to power it on by pressing the ON/OFF button and the phone came back to life without a glitch. There was almost 52% charge, date and time were spot on. I couldn't recall the pattern, as a result I couldn't unlock the phone.
I decided to wait for a while for my partner to come back and put in the correct pattern password and left the phone unattended for a while. In between I kept checking and the phone remained ON all the time.
Unfortunately, I decided to charge the phone while my partner returned. After half an hour or so I pulled out the charging cable and checked the phone for 1 last time. Phone was still ON. I left it untouched for a few more minutes.
As soon as my partner came back I told her about the phone coming back to life. She pressed the ON/OFF button to bring up the screen and key in the pattern but the screen just didn't come up. I have tried number of times since then but nothing.
Phone is dead again atleast as of now. Thinking of keeping it back for few more months and will try again.
In the meantime any sort of help will be highly appreciated.
Please note more than the phone I am keen on the data inside it. Need to recover it.

[Q] I9505 died suddenly now wont charge

Hi all, tried searching for some help but couldn't find anything of any use, plenty of similar things only but not quite the same.
Basically, my phone had been in use today, as normal, nothing different, nothing new installed. I put it down on the table while I did some work around the house, an hour late I picked it up and it was off. It had around 70% power when I last looked at it, Not only had it turned off, it was so hot I couldn't hold it for more than a moment. After letting it cool down, I tried to turn it on and nothing at all happened. I decided to plug it in and leave it to charge a bit, but when I came back to it again half an hour later it was still dead and hot as hell again.
I have tried three different chargers and even a new battery that I bought in town just this morning, thinking the battery was the problem. Still exactly the same thing happening with new battery, wont charge, phone heating up within minutes to the point where I cant hold it. Heat seems to be building up underneath the memory card slot.
I did manage to boot it up briefly whilst it was plugged in before it got too hot but had to turn it off again to cool it down. It seemed to boot just fine on that occasion. Also managed to get it into recovery and did a cache wipe as well as a full factory wipe but no difference. Again I managed to boot it after the wipe, seemed to start up as you would expect a first boot to do, asking me to set up the phone, but again it was no gaining charge and was heating up very fast so had to turn it off again.
Any ideas what the hell has gone wrong with me phone?
I have a repair pack from Samsung on route as its only four months old, so they will do a warranty repair or a swap, but while I'm waiting, thought it best to ask here if anyone has any ideas.
Sorry for such a long post, if I need to post anything more specific feel free to ask.
Thanks in advance
I experienced such before...
Phone heats up a lot and shuts off when charging. I send the phone in for repair, the service center identify it as faulty motherboard and got a replacement handset...
It is just bad quality components in Galaxy S4. Go and change your phone at service center.
Thanks for that, I had a feeling it was motherboard, processor or USB board, Was kind of hoping I was wrong and there was something I could do at home to fix it but oh well...
Does it matter that I have the new German 4.3 firmware on a UK handset with multi-csc? Knox flag is still 0x0 if that matters to warranty lol. I cant flash anything stock if I cant turn the thing on lol.
Why is the S4 such a poor quality phone for a flagship, seems to be so many faults with the phone and battery. I've had both the cracked screen issue as well as this crash for no reason. My S2 on the other hand is still going strong and working perfectly despite being dropped a few times and having had no new parts or battery replaced. Its covered in marks and dents from prolonged use and still keeps going. Had that since launch. Back to using it while waiting for the four month old S4 to be fixed.
EDIT:
Strange new development, the original battery doest do anything any more. Nothing happening at all, no charging screen, no heating up, nothing. New battery still not charging and causing phone to heat up. Did manage to boot the phone up again for a few minutes last night and besides heat and not charging, it seemed to work. Making me think its not the motherboard at fault now or surely it wouldn't turn on. No idea what's going on now.

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

Help! My Galaxy Note 3 N9005 Won't Turn On

Hi Everyone! I have a galaxy note 3 SM N9005 32GB. I've started facing a very weird problem recently that I cannot find described anywhere in quite the way I'm experiencing it.. My note 3 powered off by itself after running out of charge last night. Ever since then, the only thing that happens when I plug it in to charge is that the screen stays black and the phone only vibrates once. No charging LED indicator, nothing on the screen at all, just a black screen like when the phone is off. In order to get it to vibrate again, I have to do a power drain before connecting it back to a charger. There's nothing on the screen at all. Can't boot into recovery or download modes and it's not detected by a computer. Have tried multiple cables (USB 3.0 and 2) and have 2 batteries which were working fine till this happened.
Any idea of what's going on? And if I can back up any data from it like contacts and messages? Thankfully, I had transferred almost every app I could to the micro SD card (128GB Sandisk) and was able to at least recover my notes from colornote, but I digress. What is going on in my phone?
Additional info - the battery is probably still charging when I plug it in. I think this because the phone and the battery warm up after being plugged in for a little while just like they used to when the phone was working.
Even more additional info - I don't know if this is relevant, but I recently upgraded to the most recent OS version available. I think It's a 5.0 or something but I can't remember exactly. Also, the front camera stopped working some time after the upgrade. And 2 days before this, 2 apps refused to update for some reason. I don't know if this could be related.
TL;DR - Note 3 N9005 ran out of charge and is now almost dead with black screen and no LED but vibrates only once after plugging in or pushing the power button. To get it to vibrate again, a power drain needs to be done. The battery is still charging because it gets warm when plugged in.
I too had the same problem but when I connected the phone it would not even vibrate like completely dead.
Maybe try these:-
1)Connect it to the pc of it detects it then recovery would be easy.
2)Connect the charger properly.
3)remove battery for like 30 minutes and try the steps 1 and 2 again.
4) If still not working go to the dealer cause I had to go to him too. ?

I bought it off of amazon, any suggestions in such a case? Besides trying to send it back, I mean. Anything or tool I can try? I don't mind if it gets technical. Need to get my app data off the internal memory.
Though mine started with a different problem than yours, since today it seems like the problem is same like yours. Phone's display is totally black, yet I can go to download mode (cause phone is detected by Odin), I flashed the latest stock ROM of UK too, but now there is no change anyway. I want to be practical and think that this is a display problem, if not I will be more than happy. I have to send the phone to a local technician I know, lets see.
The only think I believe you can do is wait, for maybe 6-7 hours or so, with the battery detached, and then insert it back and see whether its booting with display on or not, if not its more likely a hardware issue, display possibly.

[SGH-I337 AT&T] Unmodified, Stock SGS4 boot loops, freezes, graphical bugs HELP!

Hello everyone!
My parents contacted me asking for help with some phone issues that I thought would be minor but this is now something I have to submit to you guys because I just don't know how to tackle this issue;
I've got an unmodified, completely stock AT&T Samsung Galaxy S4 that has been owned since launch. My parents were initially complaining about how the phone stopped charging and wouldn't turn on. I thought, "Easy, dead battery, it's been 3 years so how could it not? It might not be delivering enough voltage for the SoC..." but i'm not sure that's the full story which is why I want your guys' opinion since this place is a wealth of knowledge.
Things that are known:
When you charge the phone, the basic "battery charging indicator" that is shown when Android is not booted into or powered on freezes, or sometimes does not detect a battery so does not even turn on. Doing battery pulls seems to change how the phone responds. This is what my parents were experiencing. I thought, either dead battery, dead micro-USB cable, AC adapter, or charging circuit within the phone. Since this was obviously a big job, I took the phone back home for this weekend to play with and now this is what i'm experiencing.
So I got the phone to charge using one of my AC adapters for some reason, despite using the supposed broken charging cable to transfer data successfully without corruption using my own phone (LG G2) to confirm if it was just the cable. So now the SGS4 has a battery that is 100% charged, I turn on the phone and tried various methods to get the phone to boot successfully back into android. The first obvious one was to boot into safe mode using PWR, letting go of PWR, and then pressing VOL UP. It booted ONCE or TWICE successfully into safe mode into android, it shut off after 5 seconds being into the system due to low battery. This was BEFORE I was able to successfully charge the battery to 100% with my AC adapter but has failed to boot since.
Now since I've been failing to get into safe mode as when I boot the phone up, the phone freezes or has graphical glitches at the Samsung post/splash logo as seen here:
After some desperation, I considered using KIES/Odin to reflash, but mostly I tried going into download mode to see if the phone would even go into it by doing PWR + VOL DOWN. It did get into download mode but it froze/restarted forcing a battery pull and ever since then I keep getting occasional error messages such as "System software not authorized by AT&T has been found on your phone.", or this screen with a Samsung logo and an open padlock. I notice sometimes that when I'm at this open padlock screen, it sometimes begins to boot into the system but quickly freezes when it plays the boot jingle:
At any rate, I ordered a new battery but I fear this might be EMMC corruption or just something I don't quite understand. The phone has valuable information that I have to recover despite my parents CANCELLING a backup of the phone, they failed to heed my due diligence and are now freaking out about the data (photos, contacts, etc). I just need the phone to boot so I can make a nandroid backup, export the contacts, transfer media off the phone and wipe this thing and start anew. However i've already let them know that it might not be possible. The most important thing is to get this thing out of this soft-brick?
Please help because I have no idea where to steer this ship from here on out aside from waiting to receive that new battery and hope these instability issues are caused by low voltage. I had an SGS2 which had the crazy EMMC bug so I'm hoping its not EMMC corruption.
Thanks for your time everyone! I'll update this thread to reflect new information as I play around with the phone.
Edit: Here is a video, I go through a lot of the same information posted in this thread but here it is.

Not that I know of. I'm going to check the water damage stickers if I can to ensure that's not the case but i've been told it was sudden. It had been dropped once before but had been working fine for quite some time up until recently.
Maybe the effects of the drop and manifesting themselves now?

Samsung Galaxy S7 Edge Not Turning On

Hi people.
So i'm having a problem with my S7 Edge and i don't think it is common. A few weeks back I was using my phone and it would suddenly turn off and the battery would be drained too. After this first incident with the problem it happened more often, and the phone would start doing boot loops to the point where the phone just froze and turned off. When these problems occured it will usually need to be a problem where I do a safe boot (Volume up, Home button and power key), and everything will be fine (or to charge it if the battery drained), but recently, the phone just didn't work at all, to the point I waited for the battery to drain (10 hours), and try charging it, nothing happens.
So firstly I was watching a video and checking my CPU/Battery tempretures to see if that was the problem (the tempretures at the time were around 31 degrees), and mid way through the video it bugged out through the audio in a high screech and turned itself off.
I tried turning it on again but no response to the screen, i tried safe booting it, or every alternative booting option, it did not work at all.
Here is all the diagnostics and repairs I did, but no luck:
- Tried turning it on
- Different boot options (Volume up/down, Home button & power key)
- Cleaning the port for moisture detection
- Replacing the battery for a new one (Genuine one)
- Doing all of the above, with it on charge
- Connecting to a PC, but no detection
One positive I found was that when i put the phone on a wireless station, it would change colour to show that the phone is charging. I have however took the wireless out of the phone as it was in the way of the battery, and safely in my draw.
Before this final fault happened, I did do a recovery to a previous Android version, just incase if it was a software fault, but it wasn't. The phone is not rooted and I had it since September of 2016.
Is there any alternative options to do? As i'm running out of ideas to do as every solution on the internet is to turn it on, which i can't whatsoever.
The warranty is voided also as there is a crack on the screen lens, and it's way too much to pay for a repair.
I need some explination of why this is happening, so I can go in the right direction and not to waste money if i was going to a repair service, or purchasing the parts for myself.
Any help would be highly appericiated.
Check your installed apps to see if there any viruses on your phone. All you said are signs that your phone might have a virus (check how to remove it here: https://www.unlockunit.com/blog/how-to-tell-if-your-phone-has-a-virus/
However, there is a chance that you do not have any viruses on your phone, but at least you have to isolate this possibility.
Did you recall installing any app prior to this behavior?
This may be the case, however i can't turn on the phone at all. I tried every possible reboot possible, download mode, bios mode, safe boot, reboot, but nothing happens unfortunately. Unless i can do it whilst it is turned off, i can do something. I have a PC if i can do anything else with it.
I don't think I have installed any weird apps on the phone.
sounds like a brick to me. Not a lot I can thing of you can do.
If you place the wireless card back in does it boot?
IT sounds like you've messed with the internals, so possible you damaged something?
I don't particularly think that I broke it from the inside as it was behaving the same before i opened it. And when i used the wireless charging, it will only indicate it was charging or getting detected on that charging pad and not on the phone regarding a red led, or the charging icon
Have you tried holding volume down + home + power for 15 seconds and try turning on the phone again?
As mentioned in the description, I have unfortunately
