[Q] My SM-T900 doesnt switch on - Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble

Hey there. I am new to XDA.
My tablet last night was just fine! Everything was working perfectly and i played a few games before i went to sleep. Anyhow, Today afternoon i trying to wake up the screen of my tablet and it doesn't even turn on the screen! I put it in to charge but nothing happens. The only thing that happens is that is getting warm at the back because of charging.
So overall, last night was working, today is not even turn on.
p.s: Few weeks back i try to root my tablet and i didn't make it. I had the problem "Firmware upgrade encountered and issue. Please select recovery mode in Kies and try again" But i managed to recover to fully factory settings all over again.
Thanks

Try this tool:
http://www.ebay.com/sch/i.html?_fro...&_nkw=usb+current+and+voltage+tester&_sacat=0
Make sure the current should be ~ 1,7 Amps, voltage should be ~ 5.2 Volts.
There are many unknowns: bad charger or bad USB cable or bad USB charging port.
You should use another known working USB cable or charger to test. Another micro USB cable can be used to charge or 5 Volts to 5.3 Volts charger.
If you tablet is charging, press the HOME button it should show a green battery icon.

The problem is not with the charger, its with the software I guess

Now you will enter download mode. Use the volume keys, and navigate to Reboot Device. Press the Power key to select
Now your device should reboot

I tried the power,home,down thing also the power,home,up nothing happens. As i told when i try to charge the tablet the back of the tablet was getting warmer, a sign that says its charging. BUT the screen does not open with the battery on it.. Basically it doesn't turn on at all.

Tried that
Also tried that too.. But i think the voltage its alright i think and also i use my 7 months old original charger that came with the tablet. So the chances are so few.

Another way if you cannot see anything, try of using HDMI adapter to connect to your TV. Signs of your tablet is running: vibration at start up, sounds of start screen or menu and back buttons light up. If you see these signs, probably the LCD cable is disconnected or loose. But how do you know your tablet is charging ? The charger or cable is working but the USB charging port doesn't work, you'll have a dead battery. There are too many unknowns you're even not sure, then others cannot guess what is wrong. First thing first, you need to know if your tablet is charging, then you will figure out what is next.

Nothing!

Hey there.. Thanks for the help!
I know that is charging because the back of the tablet is getting warmer when i charge it. Also no back keys or nothing is showing up. I tried everything. The only thing i didnt try is the HDMI thing. Plus the tablet is in full silence. no vibration or anything. i dont remember if the tablet was vibrating at the turn on. The only thing i got from the tablet since yesterday is nothing. not even a light of the screen or download mode or back light NOTHING so unexpectedly
Thanks!

When the tablet shows no sign of life, the only way to know first if the mainboard is working, is is taking charge ?
The back is warming cannot tell anything. If the battery is dead you cannot go troubleshooting further unless swapping another battery to see if the tablet can turn on. Even with a full charged battery, a defective power button could prevent the tablet turning on.
There are too many unknowns, that's why elimination method have to use to find the source of problem: software or hardware.
The USB current and voltage tester will help you without guessing the working status of your tablet. I have no clues, that's why I'm guessing too.

Not even a clue!

I don't even have a clue. I search the whole internet about this problem and nothing. I will take it back to the store and use the warranty. Thats the best way

Long shot but try this. Unplug the charger. Hold the power button down for a full 20 seconds. Even if the tablet is in a "frozen" state, that should turn it off. Then try turning it on again.

[Q] ATT LG3 Won't Turn On Completely Unresponsive

I have an ATT LG G3 yesterday it the phone suddenly won't turn on. It was on with mostly full battery and now won't turn on and is competley unresponsive. When I plug it in, no charging light comes on. Additionally I tried the hard reset by holding down power and down volume key; this gave me nothing.
Thinking that it might be a battery problem, I left it plugged in all night. But still nothing.
Any ideas?

I had the same problem and pulling the battery wasn't cutting it. This worked for me:
1. Take out the battery
2. WITH THE BATTERY OUT OF THE PHONE AND NOT PLUGGED IN, press and hold the power button for about 15 seconds.
What this does is it drains all the power stored in the phone and takes the power source away so the phone can fully reboot and refresh the power cycle.
3. Replace he battery and plug in the phone to the OEM LG Charger that came with the phone.
4. Let the phone charge for about 15 minutes then try to turn it on.
This worked for me but some phones are DOA being the phones are still in early production. It takes a few months before they work out all the Kinks.
I figured I'd add my two cents. I had the same issue with my D851 (T-Mobile) version. I was copying a file over my from computer and halfway through the phone shut off. I thought the screen timed out, but it wouldn't turn back on. I pulled the battery, tried holding the power button without the battery for 60 seconds, putting the battery back in, charging without the battery... nothing. The LED would never light, and the phone would never turn on. I contacted LG and it's currently on its way back to them for replacement.
I work for a wireless service provider and not only sell this phone but own one. I also had the problem and unfortunately the battery out power combo did not work for me either and swapping the battery was to no avail. I have seen one other DOA as well. I have noticed the new LG models have had some significant flaws and lemons when they've first come out but I feel the specs and price you get are worth the risk so if this does happen to you I wouldn't throw in the towel on LG quite yet. However the way LG reacts to this will speak volumes to the company's overall success in the industry.

what would happen if I tried returning my phone with root and another rom on it and it won't turn on?
I tried manually going to twrp but went to recovery instead, restarted phone and now it won't turn on. I've tried the suggestions in this thread to no avail.
Won't turn on
My LG G3 D855 first had this problem of restarting on its own when I play with its camera and while restarting, the phone is getting warmer. And now, it wont turn on. I press the power button while it is off, it tried to turn on until the LG logo screen and then it shuts down on its own and restarting non-stop until that LG logo screen and turning off again. When I plugged in a charger, it manages to turn on but only to the pass code part and then it turns off again and the battery charging screen when phone is turn off, is displayed. The battery showed was higher than the battery showed when during the pass code stage. Is it the battery problem? I haven't send the phone to be check yet, I hope its the battery..
Clearing phone
My won't turn on either. I filed an insurance claim and am getting a new one. But I have to send my old phone in. I was wondering how I can get all my info off of the old phone before I turn it in. I don't want some one to get my info that is on that phone. How do I clear it all with it not turning on. Is there a hard drive from the phone I can remove?
yes for i have solution if u want to turn on your phone ...
First put phone on charging and then turn it on after 10sec (dont remove from chargning ) when its completelty on ... then remove from charger ...

The plan: Put the phone into recovery and then push " power on".
The method: To get into recovery, push power and volume down together until you see "system recovery" ( it will take a while- maybe more than a minute) and touch "continue power up" by depressing the power key.

h! i have rooted my G3 and insatll TWRP it works .. but when i press volume down+power button it wont boot to recovery. ? i can easilt boot to recovery using ADB .. but how can i boot to recvery using power and voulme keys ..
http://lgg3root.com/lg-g3-root-tutorials/how-to-manually-boot-into-cwmtwrp-recovery-on-lg-g3/ Said better than I can. Be sure that you are firmly pressing both on the power and volume down keys, at the same time, don't give up- To be sure I have constant pressure, I take off the case. I do this each time I restart the phone.
Oh awesome. I was browsing the web having the same problem and this totally fixed it for me. Cheers!

Help, my tab won't turn on or charging

Hi guys,
This morning I powered on my tab, then, after reading some news, I closed the cover lid and when I came back after some minutes my tab won't turn on or charging. Battery is full (charged over night).
I tried power + vol + home: nothing.
My tab: 8.4 lte rooted with Odin, Samsung v2 Rom
What a strange coincidence! Mine too!
My Tab S 8.4 LTE turned off after a complete descharge. I've attached it to charger, without turning it on, and charge beguns.
After a couple of hours I've checked the tab but I've found it completely turned off, no charging animation on power button. I've tried to turn it on but without success.
I've a SuperSamsung V2 ROM also.
What's the f..k????
---------- Post added at 01:10 PM ---------- Previous post was at 01:01 PM ----------
Thanks God, I've resolved with this
http://forum.xda-developers.com/galaxy-tab-s/help/to-event-soft-brick-disaster-t2838473
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.
Now the tablet has rebooted and it works fine!
When I'll be at home I'll try...hope it will work for me also...have you some random reboots while in standby in the past days?
No chance for me...
My Tab S 10.5 Wifi running on stock rom is at reparation center because of the same problem...
Well...After two days...I think the problem is something wrong in battery. My tab was fully charged when this issue happens for the first time. After leaving it alone on the desktop for a day, this morning I connected the tab to my PC for around 30 minutes and the charging battery appears on the screen. I charged for 20 minutes and after I let the tablet discharging. This evening battery was 8% and my tab went to black unresponsive screen. Now I'll try charging to full and after clearing battery stats to see if something change. ..
@kraoc please let me know reparation center diagnosis
Mine has repeated this behaviour several times in the last few days, I've always solved with the procedure in the post #2, but now it keeps irritating. @kraok please let us know diagnosis. @davidebeatrice I don't think so since it has just happened to me while using the tablet with 70% battery.
I was 99% when it happens for the first time...now my tab seems T9 work fine. Let's see when battery will be down down down...?
After two charging-discharging process and finger crossing, I can say that clearing battery stats worked for me.
Hello, I've a similar problem. My rooted Tab S with TWRP doesn't boot anymore, it's stuck at the Samsung logo. However I can get into download mode or shut it down and the loading animation shows. Probably caused by some root stuff I installed because it worked fine before. Any way to fix it via Odin or some other ideas?
Thanks!

If you have access to download... just flash stock rom...
I've had a similar problem:
Screen shows a discharged battery and I can't do anything to it.
No button combination works, plugged or unplugged.
After a while (days) it shut off. I couldn't turn it back on until plugging it, and then the same battery discharged display shows up.
I took it to a service center and they blamed the motherboard, but I had a custom ROM (a version a Cyanogen found here). No fun.
EDIT: FIXED!
I retrieved the tablet before they serviced it, and attempted to repair it myself again with the button combination.
I used the home + vol down + power combo, and then I pugged it in. It went to download mode, then I pressed vol down to restart the tablet.
Method similar to this (but without the need to restore my backup or flash anything):
http://forum.xda-developers.com/galaxy-tab-s/help/to-event-soft-brick-disaster-t2838473
Hope this helps someone else stuck in the same situation.
I had teh same thing happen to my 10" Tab S as well. Took it back to Spring and they immediately replaced it since I had only had it for 7 days tat that point.
Glad you had a new one... And I'm a bit jalous about your issue
Had it for 2 month... Got 2 reply from Samsung: "rooted and can't use warranty" !
But: Flashing your device does not void your statutory warranty - FSFE Legal - http://j.mp/ZIPbWC !!!
Samsung keep to refuse to apply warranty !!!
Hello everybody,
I've sad news from my side...
I've had this problem a few times and I've everytime resolved with the home+vol down+power combo and restarting.
After that I've found evidence on another thread here in XDA that it should be related with battery stats.
After resetting the stats, the problem stopped, up to yesterday night.
I was watching a video on YouTube where the battery goes 0% and the tablet shutdown itself.
So I've attached it to charger and the charge begun (tablet was off, battery charging appears on screen).
This morning I've detached it from charger without checking if it was 100% charged but when I've tried to power it up, I don't get any reaction from the tablet.
The key combo doesn't function anymore. Attach to PC via USB doesn't make it to get recognized. No way out.
Completely dead.
Have you some suggestion/trick I can try before I'll launch it through the window???
Thanks
Antonio

But I can try your tip, if only I'll found a way to open the tablet.

Google how to fix the screen or something of the like..... ifixit usually has a tutorial and the first couple steps will.be removing the batter

Thanks again for your response, blap017
I have good news, however.
Today I've reattached the tablet to the charger and it gets charging.
I've leaved it up to full charge, then I've turned it on and it now it functions well. Thanks God.
But I don't understand why this has happened. Perhaps the SuperSamsung v2 rom messed up battery stats...
Thxs everybody for the support, xda forums are ever a fantastic source of inspiration!!!

[Q] Phone does not turn-on upon "Restart"

Good Day,
Phone:
Asus Zenfone 2 ZE551ML (ASUS_Z00AD) - 1.8GHz, 4GB RAM, 32GB storage. (Not Rooted)

Problem:
My brother couldn't update an application in Google Play Store. He tried to restart the phone through Hold Power Button -> Restart but the phone does not turn-on anymore
Methods Tried:
1. Hold the power button around ten seconds. The phone slightly vibrates but still does not turn on.
2. Hold the Volume Up + power button for ten seconds. The phone slightly vibrates but still does not turn on.
3. Charge the phone using provided Asus charger and try to turn the phone on. Still, the phone slightly vibrates but still does not turn on.
4. Tried charging the phone for around 30mins and the phone gets warm. Tried turning the phone on but still, same results.
Please help advise for solutions or possible fixes. Thanks in advance.
Regards,
Ed
Please ensure to use the bundled AC power adapter and micro-USB cable to charge your device. This model may not come equipped with 18w Boostmaster adapter and will require longer charge. Please see http://www.asus.com/us/support/Sear...5-480F-AADA-FE49EDD81C01/?keyword=boostmaster

Thanks for the quick response. Yes, the bundled AC power adapter and micro-USB cable is used for charging. The AC power adapter output is 5.2V and 1.35A. Also tried to charge the phone for a few hours but still, the same problem is encountered.
Does the LED indicator light up when charging? Have you tried charging while being connected to a PC? (this will take longer to charge)

Sorry for the late reply, sir. Many thanks for the prompt responses. As advised by my brother, he tried charging it again using the AC charger for more than two hours and turned the phone on. Good news that the phone booted properly.
It seems that the problem is really about a drained battery. This issue can now be closed.
Thank you very much.

Hi Sir santhosh_kv,
My brother's phone couldn't be switched on before and we just sent the phone to the service center. After a month or two, they replaced the unit with a new one. I think my brother got a lemon unit before.
Thank you.

Maybe there's something wrong with the system. Try flash stock rom using adb sideload. While in that dead android symbol, press power+vol up to go to recovery.

Hi Sir, I have tried the procedure u said. But nothing seems to be working. Please help me with this. I have installed the ABD divers and updated it. But its not working after re-switching on.
After using the phone until the battery was completely drained, I tried to charge it. Initially the indicator showed orange (suggesting it was charging), but after attempting to turn the phone on, it vibrated once or twice and the indicator stopped glowing. The phone has since failed to turn on at all, and connecting the charger no longer shows any sign of charging (ie. no orange indicator or on-screen battery icon).
Has anyone eno****ered this issue, or know of a way to fix it? Let me know if I can provide any more information, and thanks
I have recently bought asus zenfone 2 ze550ml in september,when i connected my phone to laptop it suddenly got turned off and it is not at all restarting i tried many ways like i charged for an hour and tried to on it but i am not successful its not at all responding the light on the top is not even blinking.....and no vibration too
what to do...?
Hi I have the same problem. I have also tried to charge it for 2 hours. The phone vibrates when pressing the power button or the power and up arrow button simultaneously or when the charger is plugged in but does not show anything. The screen is black. The led indicator also does not show any light.
Hi Im having the same problem, I was charging my phone but it is not charging when i notice it was a bit warm what I did was I restartedmy phone and it did not turn on anymore. I tried the reboot process of holding the power button and volume but it wont start it just vibrates, have done the charging it for almost an hour but it still wont turn on. what to do about this, Asus Zenfone

Power button not working. How do i boot up?

So my power button hasnt been working for some time and i cant boot up. It wasn't that big of a problem for some time since i managed to double tap to wake and to put it on a charger and it would boot up after going over 5%. I've just installed a new ROM and it won't boot up its at 25%. Is there a way to boot it up somehow using a pc or something? I have usb debugging enabled and tried starting it up using adb but it doesn't recognize the phone.
When phone is turned off, hold volume up to go to download mode, then press volume down to abort it, he should reset and turn on then.
Or connect cable with volume - pressed to enter download mode.
If your power button is not working, try removing it, cleaning the dust, repairing it, if necressary, it will be easier to boot that way.
PS: If you try it, make a video, or photos, cause you need everything in its place.

In all seriousness though
I'm not sure if the power button is yourissue, you need to make your post a little clearer
My phone has a wearing button, so every time I press it it doesn't always work
You are saying your phone isn't recognized? Did it work before? Did this start happening recently?
I don't think your issue is power button related.
make sure USB debugging is turned on in developer options. That is necessary for adb to connect to device. Try that before the battery....your device should be listed when u type adb devices with USB debugging on. If not what does it list?
It sounds more like the battery. If the phone keeps looping and takes time to sit on charger to power up and battery percentages seem off......then you need to get a replacement battery. I suggest getting an extended battery, there are a lot of knockoff LG batteries online. I've bought one myself and yes its almost identical...but the ink is faded and the top plastic is slightly different. It just did the same thing you are describing
Powerbear, zerolemon are good. You get what u pay for.
Tip: heavier the battery the better quality it is. Your replacement battery should weigh same as the one you currently have if your going to get the LG one

Model G3223 - Charging Issues and Black Screen/Flashing White Light at Boot

Hey everyone,
So, I got a new Xperia XA1 Ultra (G3223) through a trade running stock Android 7.0. Checked everything and initially it looked fine.
Over the last few days, things have been acting weird. Every time I start the device, it gives me a blank (black) screen with a blinking white notification light - it doesn't even show me the boot screen at times when it boots. Just yesterday, I got it to boot by pressing VOLUME UP + POWER after being in that state - but, that's not normal. Does anyone know why in the world my phone does that?
Furthermore, when using the Sony charger that came with the device, it takes over 6 hours to charge and doesn't even show the charging sign while charging. Could this be an Android 7.0 bug or is something seriously wrong with my phone? Only one time since I got it, did I get it to charge normal with the charging sign and everything; it actually charged quite rapidly at that point.
Any help would be appreciated with this, guys, because I'm at a loss. I do want to mention that the device doesn't seem to be recognized by the computer, so I'm not even sure that the cable is original.

Try a new cable and/or charger. (I found I had a bad charger once)
Since you had computer issues, I'd start with the cable. Also check the charging port on the phone for debris/damage.

Okay, I'll do that - but, do you have any idea regarding the blank screen issue, my friend?

How is your phone turning on? Power button or inserting the USB cable?
Only thing I can think of is perhaps a stuck volume key placing the phone into recovery or flash mode.
Try turning on the phone with no USB cable attached. Before you turn it on, press the volume keys a few times to make sure they aren't stuck and then power on.

The thing is that it's weird.... For one, sometimes when I use the touch reset/turn off button, it takes at least two minutes to reset, or it doesn't even reset. Then, when I turn the phone on while it's off, the phone sometimes enters into this weird state with the flashing white notification light. I never power on the phone via USB cable, so I don't know, really. Yesterday, I shut the phone off to test it, plugged the phone in to charge it, it wouldn't charge while off, but then hit power on, and then it wouldn't turn on, so I used VOLUME UP + POWER, and then it turned on just fine.
Hi
Happened also to be with my older Xperia J.
Backup your phone (cause you'll lose your data), connect it to a PC (or Mac) and install Xperia companion, then select "repair phone" or something similar (I know the written in Italian version ).
Wait and it will be all fine.
