[Q] Galaxy Tab S - LED Flashing - Won't turn on - Galaxy Tab S Q&A, Help & Troubleshooting

Hi, was wondering if anyone else has/had similar issues?
Got the Galaxy Tab S today and was spending time setting it up. Connected to the PC and charge was at about 57%. Suddenly the window displaying tablet contents on the PC disappeared and the screen went black.
The power button didn't turn the screen back on. I held it down, thinking that it required a hard reset but nothing happened. I disconnected the tablet from my pc and went to use it's dedicated charger. The battery icon came up, stating it was 57% charge, and shortly after the LED light on the back of the tablet started flashing rapidly. I quickly took out the cable.
I've tried holding down the home key, volume down, and power button and nothing happens. I then tried the same and having a finger on the screen. Then I repeated the process again with the cable connected to the charger, and then computer.
No matter what I try, the device won't turn on and the LED keeps flashing repeatedly when connected with usb charging cable. I also tried using another cable.
I'm thinking of phoning up where I got it from tomorrow and asking for a replacement, unless there's something I'm missing here?
Any thoughts would be great, thanks.

My guess would be, you are not pressing the buttons correctly.

You try just Power+Vol Down?

I tried that just now. Nothing happens.

How about pressing power, vol up and down, home huttons at the same time for 1 minute

That doesn't work either. The only response I get from the tablet is by plugging in the charging cable and then it goes on to display an epileptic inducing light show with the LED constantly flashing on and off

Never seen this problem before. Could be a bad partition making it not boot. Replacement may be your answer as its better to get a new one and be safe.

I've used various tablets before and never encountered any of them not booting at all. The led flashing business is very weird. I'll phone up the store I got it from and ask if I can get a replacement.
Thanks for the responses

[Q] [ION] Please help with possible hard brick, I've read other threads

Hi, today while I was browsing on Firefox, the app closed by itself and the home screen got distorted (the wallpaper got black and some icons started to show up in the background). Since it has happened before, twice in the last week, I tried to reset the phone. However this time the phone did not turn on. I put it in the charger and the LED is also not turning on. I've had it plugged in for about 9 hours now and the LED is still off and the phone is not even getting warm, like it usually does when it's charging. The charger is also not warming up, and when I tried to connect the phone to the computer USB port, Windows doesn't report any power consumption.
I've read some threads about bricking, so I know people mention longer times to get the LED turn red, but is it normal that it doesn't warm up and doesn't suck any power from a USB port?
For anyone familiar with AT&T operations, if I sent it as warranty replacement, would they bother running diagnostics? I have it with LT28i .68 firmware, rooted and with CWM.
Also, is there a way to retrieve the data from the internal SD card? I tried connecting it to the computer and nothing happened. Nothing happens when I press either volume button + power button. An nothing happens when I connect it to the computer pressing either volume button.
Any help will be much appreciated.
Have you tried the Hard reset?
Holding Power Button and Volume button together for at-least 3-5 seconds and you would feel 3 vibration.

Hold VolUP+VolDOWN at the same time, and then press Power button, holding it too, the 3 at same time for some secs...

Does ION has removable battery? If yes try to remove it for a while.
If not. Then try the buttons combo with the phone connect to charger...

The Ion doesn't have a removable battery. I already tried all combinations of power+volume buttons, while disconnected and connected to the charger, and nothing. Maybe the battery somehow got disconnected internally, I don't know if that's even possible.
I've called AT&T, they'll send another warranty replacement, the second replacement I get. Hopefully this one will last enough at least for an early renewal.
I don't know if AT&T still does this but back when I was in the states last year I had them give me an early upgrade because two of the handsets they gave me were faulty (original and one replacement). Try talking to CS Reps sometimes it pays off. You might be able to get an early upgrade if you tell them how this can't keep happening you have important data blah blah blah.
Anyways good luck!

How I "fixed" a "brick" on Xperia SL

Hello,
I'm a new user and this is my first post here. I felt the need to "contribute" with my somewhat of a unique case.
I bought the Xperia SL 48h ago, and managed to "brick" it. The phone just died on me during regular use, I was in astro manager at the moment of the brick, the screen gradually turned off, and the phone became unresponsive soon afterwards. It didn't react when I plugged in the charger or when I connected it to my pc, the LED was dead, power + vol up button combo was also useless, and the pc saw my device as "QHSUSB_DLOAD".
I managed to solve this issue by holding power + vol up button combination for four (4!) minutes. I didn't really have a stopwatch, but I was in the bus on road to the store to return the phone, and just thought I might give persistence and stubbornness a chance. Three bus stops later, the phone vibrates and just turns on normally, like nothing happened.
I don't know how bugs like this occur, nor do I know how to prevent them; I am going to pretend this was just a work of gremlins.
Bottom line - if power on + vol up button combo didn't work for you for a 5 second, 10 second or a 30 second time-span, hold them buttons for a couple of minutes and pray that it works. I hope this helps someone.
Best regards
Did it have enough charge?

Seems your phone got stuck and turned the screen off.
Holding power+volume Up forces it to shutdown without messing with the battery-removal.
So you might have been able to restart it successfully.

The battery was at 14% at the time of power+vol up wake up. I didn't charge it though, I plugged in the charger just to see if there was a LED on, but there wasn't any LED response whatsoever.

That must be it. At the moment of the brick, screen gradually turned off, with darker colors becoming instantly black, and brigther colors getting a yellow tint just before everything vanished from the screen. Thing is though, the phone didn't react to the power+vol up combo right away, but two hours later and almost four minutes of holding the buttons.
One more thing that I noticed was, when the phone was connected to my pc, if I held the power+vol up, the pc would add/remove my hardware in a cycle, or at least play the sound of a device connected/disconnected. The phone still remained dead, but returned later for a miraculous wake up.

I'm not an expert, but this is probably your phone entering fastboot mode and then being disconnected due to incorrect drivers on the PC.
Glad your phone came back though. Comatose phones are terrifying, no?

I tried several times.. nothing happens... any other suggestion please
Power+voldown+home.
If this does not boot, you could try with usb dongle.
Or full run down to empty battery.
Next chance would require to open it.

It's not bricked so calm down. It just had a cyber stroke. It will be fine just let the power run out and recharge the battery so u can turn it on again. Same thing happened within days for getting mine.
yes... I am waiting for the battery to be completely dead. so far its on...taking calls and sms..I don't howmuch % of batter is left cause I can't see it.
I had the exact same problem once....and i had a hunch that the screen was fine, it turned out it was thankfully....but....im aware that on 100 percent battery in standby it can last a good week or so....i was too impatient...so i ran my fingers around the edge of the backing and slowly was able to pull out the back of tge case and unclip the battery...worked straight away when turned on.
But also what i discovered does reset the tablet forcefully is holding power, vol down and the center button at the same time....try it a few times for a minute each time...if successful you might get a message about being in download mode but then just do the same thing again but imidiatly release your fingers once you see the screen go off from download mode or it will just go bavk into it...good luck m8
Have you tried holding down the power button for awhile, like 30 seconds? This should shut your device off....Then take it from there.

Seriously on my tab right now i just held vol down, power and center button whilst on and after 25 seconds screen went black then gave the "are you sure you want to enter download mode." Then i tapped vol up......t805 as well.
Battery completely empty.. tab S turned off, i plugged in the charging cable (1 ) battery meter does not appear (2) Power+vol does not work for me.. if it does.. i can't see because of the dead screen...
i have 2 options now..
(1) send it back in warranty.. this will take a lot of time and they will only fix not replace.. i guess
(2) open it and fix the display.

Hello,
Did you finally got some result?
I have exactly the same problem with a Samsung Galaxy Tab S 10.5. The screen suddenly went black although the light leds (home, back) were on.
I tried different combinations of buttons, usb charging and nothing. The only difference is that now the light leds are off.
---------- Post added at 08:46 PM ---------- Previous post was at 08:32 PM ----------
I have achieved to boot up the device because I have heard the start up sound and some notifications. However, the display doesn't work at all: the screen is black and there is no response when touching it. In addition, the light leds of the buttons are off now even when I push the home button.
Volume keys are working (I hear the sound then touching them).
Hard reset is VOLUME DOWN(left side on a 10.5) + POWER. Hold until it restarts.

But I can't figure how could this happen in a new (2 month) high-end product... I think that I will have to use the product warranty with the cost in time it involves.
This has happened to me twice during the last year. The last time was just ten minutes ago. I tried everything mentioned in this thread. VolUp+Home+Pwr for a looong time. Just PWR for a long time. I saw on my Wifi Router that the tablet was connected, but no screen. What helped me was to do a combination of everything mentioned here. What eventually got the screen on was 1. I turned of my router and 2. Home+VolDOWN+PWR for (what I believe was) 10-15 seconds. Then I got the choice to do a normal restart or a device reset. If you come this far, be sure to press VOL DN when asked. Otherwise your data will be lost. Obviously, I can't say if the router pwr off was necessary or not.
What's really weird is that my LG G3 went into a boot loop at about the same time (less than five minutes apart). They are not connected other than using the same router. I've had my LG G3 for exactly one year without ever experiencing a boot loop. The LG G3 is rooted, but my SM-T805 is not.

It's easy fix, most of the time due to loose LCD cable. If you can hear anything on the background but blank screen, 99% is loose cable.
Remove the back cover, disconnect and reconnect LCD cable, make sure it's fully inserted, then secure the connector with tapes. Test by plugin to charger, press the HOME button.
If you do correctly, the battery icon should show up on the screen. Then put back the cover, you're done.

Tablet won't turn on / charge

Hi,
I've only had my Samsung Galaxy Tab S for a few weeks. Whilst on a plane the battery went to 0%.. no problem I thought as I'd simply charge it when I got to a power source.
However, when plugged in, nothing happens. No LED light, nothing on the screen. I've plugged it into a wall socket and via USB into a PC. I have held down the power button, home and volume down for a period of time, as well as just the power button and volume down.
Has my tablet gone kaput?
Cheers,
Titanium
I'd just let it charge for a while. It'll take a bit before it comes back to life if it was completely drained.
If you still don't get any response hold POWER + VOL DOWN.

I had this problem.
You'll have to pry off the back cover, remove the wire that connects the battery to the motherboard. (A battery pull, basically).
Keep it off for 30 seconds. Then plug back in.
Use ifixit for details about opening. Feel free to ask for more help.
Try this one.
1) connect the tab to PC
2) press Home, Vol Down and Power simultaneously up to a screen appears;
3) press Vol Down to cancel and reboot the tablet.
John.
Now there are a few things you can try...
First check your charging port for any dust or any foreign particle. There has to be a small gap between the base of the charging port, and the small slab above it. Carefully, using a board pin, try and push that slab a bit up, don't apply too much pressure, just enough to make it move slightly!
This can happen sometimes if you drop your phone.
Next, make sure your charger, and the USB cable are working fine.
Also tell me if you have any Xposed module for your battery installed on your phone!

Thanks so much for that.
This morning, I plugged my tablet in to AC charge before leaving for the day -- battery was at ~30% and all was well. This evening, I came home and the tab was stuck at a weird Samsung logo -- not the normal boot with colored ovals, but the logo surrounded by a moving star field, never seen before, and could not get the tab to respond, turn off, do anything. Tried many wacky suggestions found on the intertubes to stop/start it, including holding power plus touching the screen for > 30 seconds, none of which worked. Never would have thought your suggestion for download mode would work, but it did on the very first try.
I'd like to know how the tab got into that state, and what that star field logo is about. But at least it's working again, for now.
Thank you.
That's the normal lollipop boot screen.

HTC 10 Unresponsive & Can't Restart But Alive

I hope I'm posting this in the right place but I'm desperate for help.
My phone, HTC 10, froze and then the screen turned off while I was taking a picture.
The charge should have been around 80%.
Symptoms:
The screen is unresponsive.
Couldn't get the home button/finger print sensor to turn the screen on.
Couldn't get the power button to turn the screen on.
A call to my phone could not reach my number as well.
When plugged in to a wall charger or laptop no indicator light turns on.
When connected to a laptop, the laptop makes that connection noise and a long name with QualComm in it shows up.
Tried Power Button + Volume Up for 10 seconds but didn't get any result.
Side note:
The power button was a little faulty before as well.
You have to squeeze it a certain way to make it work.
I need to somehow restart my phone. Any ideas?

Try to clean all buttons really well, if it keeps failing to boot and the phone is still recognized as Qualcomm it's probably bricked.
Simple explanation of the word bricked :
When the phone doesn't boot, when you can't access the bootloader, download mode or recovery it's bricked!

Strange turn of events: I plugged the phone to my laptop because I read somewhere that it drains the battery. Just for the kicks, after a few hours, I unplugged and re-plugged my phone. Suddenly, there was light. The battery light came back. I immediately switched to the wall charger and once I did that the battery icon appeared showing 1%. Now, it's peacefully charging away. Will see if it actually turns on later on once it's charged about half an hour.
