I/O Edition Won't Power On

Hi Guys,
I recently moved and just took my I/O edition Tab 10.1 out to play with but it won't power on, won't charge, won't do anything. Any ideas?????
I had updated it to 3.1 and it sat for approx. 1 month without use. I plugged it in to the AC Adapter and left it for about 5hrs, came back and still nothing.
Help will be greatly appreciated.
Jeff

Best bet is to call the Samsung number on the back if the tab above the serial number. They were really cool and even sent a prepaid postage I just had to provide a box to ship it in.

someone i know went through this recently (was retail).
do this:
hold power + both vol buttons for 30+ seconds.
now see if it will turn on.

Pershoot is a genius.. But, if that doesn't work, try this thread out for size. http://forum.xda-developers.com/showthread.php?t=1130574
If that sdoesn't work odin the european touchwix rom located in the developers section.. I was stuck on bootloader and that did it for me.. Good luck man... I know I felt like **** when I thought I had no hope...

It is not good for a device to leave it unused for a month. The battery might be dead for good. Best practice is to leave the battery charged at 50%. This is what I read.... I am not an expert, and and I hope that this is not your case.

Update:
No go on anything. The unit will not power on and is not recognized by the computer.
Any other suggestions? I don't want to have to send it in.

Damn homie, if that thread didn't work for you I'm out of ideas.. I'm sorry. Looks like you are going to have to contact samsung..

Place two finger tips on the glass and hold the power button until it turns on. This happened to me a few times on my retail tab 10.1. It works for me everytime.

Did you try holding the power button down for an inordinately long time? I started panicking this morning when my tab wouldn't turn on and so I held the power button down for maybe like a minute then it decided to turn back on.

Power button not working

Hi guys.
My Galaxy Note 3 power button has just completely stopped working. Is there a setting that turns off the power button functionality that I might have accidentally pressed?
Cheers.
Edit: I should elaborate here. The phone is switched on, everything works as normal but no matter how many times I try it, the power button just not do anything (holding it down, pressing different areas)

Did you try a battery reset? With the phone off, can you get into either Download or Recovery mode? That would eliminate the possibility of an OS issue.

I kind of scared to turn the thing off in case I can't switch it back on. I'll try it though.
Edit: It's dead. Taken the battery but can't switch back on now. What a joke.

I know I kind of expect this bad luck these days after having two faulty Nexus 7's. My Galaxy S2 power button is still going strong after 2 and a half years but the Note 3 lasts 7 hours

It's a dud mate. Faulty unit.
Just send it back and get it replaced.

Just send it for replacement. There's a reason phones come with a warranty that covers manufacturer defects. Whining about it to strangers in the forum is not going to fix it for you.

Yeah this is definitely the least friendly of all the Android forums. Sorry to hear you have a dud unit mate. Get it replaced.

My power button is not working to turn the screen off. Long press works to bring up the power down menu or to do a hard shut down. It works to turn back on though. Seems to happen after I plug it into the wall charger. Restoring a nandroid backup fixes the issue.
Not sure if it's related but my PC's USB crashed after trying to plug the phone in and use USB 3.0 to transfer files. I had to refresh my W8 PC to get the USB working again.
I have the Sprint version, rooted and running JellyBomb.

Hello bro...Me to facing same problem of power button issue.But my phone was able to get into recovery mode and it is also turning on.After doing hard reset also still the problem not solved.My phone is working perfectly but only problem is I'm unable to lock and power off the phone.Please help me dude.

I have the same problem. my power button is done for. whenever i need to start it. I plug it in and go into recovery and reboot from there. I also use this https://play.google.com/store/apps/details?id=com.plexnor.gravityscreenoffpro&hl=en for screen timeout and lock. And you can also get exposed and gravity box and there is a status bar tweak to double tap the status bar to lock screen (put phone to sleep).

I tried everything then found the solution on another website
My note 3 has been with me for almost 2 years now and it's power button stopped working about 2-3 months ago. Until now I avoided draining the battery below 2% and was fine but just today I dropped my phone and it shut down. I knew that my power button didn't work because of hardware problems so a soft reset didn't work for me. What I found however is that if your power button is dead you can just very quickly remove and re-insert your battery and your samsung device (I have no idea if this works on other brands) automatically boots itself. I'll give the link too incase I wasn't clear enough and I hope this helps people who shared my worries.

Phone Won't Turn On After Reboot

My phone has the 11-20 build of Gummy on it, I just updated the firmware to MJA (hoping to get data) and it was running well for the past hour. I rebooted to recovery to try installing the Euroskank rom and now my phone will not turn on, it had more than 90% battery when I rebooted so I know that is not the issue. When I plug or unplug it from my computer, it will acknowledge that something was plugged in (by making a sound) but not show what was plugged in. Any recommendations as far as what I can do to fix this?

I held down the power button long enough to watch a couple plays in the Ole Miss game, pulled the battery and put it back in, no luck. I plugged it in and did not get any battery notification. I did find that by holding the power button while it is plugged into my computer it seems to power on and off on some level because it would alternate plugged in and unplugged sounds, still with nothing else being shown like the option to view files or see anything on the phone screen. Is there anything else I can do?

Well all you can really do is make sure your USB cable charger is working, let it charge without touching it for several hours, could also be a battery problem /hardware problem? Any one else? Have any advice??
I have bricked my phone pretty bad a few times, but I have always at least had the battery icon on the front show up,, hopefully a full charge well cure it,, just Checking but by power you mean the top right botton if the phone is facing you?

Not from what I can tell. The screen doesn't show anything, the LED doesn't light up. Is there a trick where I could trigger it using ODIN or HEIMDAL?

Put battery in phone and charge for 2 to 3 hours without turning phone on.
Take battery out of phone and leave it out for 1/2 hour.
Then put battery back in and see if you can get into 'Download Mode' - Hold Home Button AND Volume Down Button at same time and while keeping them held Press the Power Button till you get screen asking if you want to go into Download mode by confirming with a Volume Up press.
If you can get there maybe you can use one of the Odin/heimdal methods to recover.
Or even more simply - Odin Philz recovery and flash an MJA ROM - That's something I'd try first if you can do that.

I just charged my phone over night, pulled the battery for an hour and still no response from my phone what so ever. I would be ok with a total wipe if at all possible at this point as it does not seem to be booting at all. Could this be a bootloader issue somehow? I updated the firmware not long before this issue occurred and it booted up from that for awhile and this issue started after trying to reboot.

At this point, your best bet is to take it to Sprint and get a warranty replacement. Not much you can do if it won't turn on

Ok...just curious does anyone here have Ting and have tips about doing this through them? I don't actually have Sprint directly but use Ting.
EDIT:
For anyone following this, potentially in a similar situation, I found this service which I hope to hear back from soon, it says they can fix hard bricked phones on their site:

My sister's S4, which is running stock unrooted 4.3 is going through the exact same thing. The Sprint corporate store told her that she needs to have it serviced by Samsung >.>

Why don't you make a usb jig and force it into download mode,I think I seen a video on you tube on how to make one,I haven't tried it myself but I heard they work
Sent from my SPH-L720 using XDA Premium HD app

Just checking, didn't see this confirmed. The screen is non responsive currently, but you said that using the power button yields USB acknowledgement..
Have you tried a complete power down and boot in to Download mode (Power + Volume Down + Home) and then plugging it in and seeing if ODIN recognizes it in Com? It is possible (although not super probable) that you are experience a flash screen/screen on issue that could potentially be repaired by a reflash.. I know a lot of the 4.3 updated were experiencing lack of flash screen but if left alone the phone would still boot.
Worth a try, if you haven't already.. Stranger things have worked for me in the past.

We did the first two steps you mentioned, got it to turn on, then it it did the same thing again after a little while. We repeated the two steps, factory reset, and all has been well for the past 24 hours. Thanks

Glad you got it working!

Yeah, I've been seeing other people having similar problems after updating even on other carriers. My guess would be that the problem is related to going from 4.2 to 4.3 coupled with user data/cache of system apps and Knox, but I really have no idea. Anyway, Thanks again

Well scratch that, it's back to its usual behaviour. Could flashing via odin fix this or could it be a hardware issue? I still feel like it's related to the 4.3 update.

Re-flaching Odin may fix it.
But it could very well be a hardware issue. I've had a couple of phone with batteries that were fairly new have this issue. Got new battery, charged and replace it and all worked.

Won't start up help needed

Okay about two weeks ago I updated to 4.4.2 from 4.2.2(I think that's the one?) on my s4 and I've hated the update. I decided to root my phone using muniz method and it worked perfectly. I even changed to the nc1.
So, after using my phone without issues for two weeks roughly I noticed last night it started to randomly turn off while texting. It would just auto restart but it happened every 5-10 minutes. After an hour it started happening more often so I plugged my phone in. Now my phone will not even turn on. When I insert the battery the samsung start screen appears for about a second and then goes black. I have to pull out the battery for the phone to do ANYTHING. If the phone is plugged in while trying this and I insert the battery I literately get NOTHING. No samsung screen or anything.
Things I've tried.
Swapped the battery.
boot into odin
boot into safemode
plugged it in while trying to boot
Swapped the usb cord
taken out sim card
Some things to note is that I did not install any new app before this had happened. It was working the same for about two weeks with no issues.
When plugging in my phone to charge or anything I never get an led light at the top of my phone.
I seriously need some help with this. Any suggestions are appreciated!

Yeah using stock wall charger from a wall, computer, and even a different charger.
Is download mode the one where you hold vol down + power + home?
If so it brings up the screen that asks you to press the volume up but it dies before it can ever make it to the downloading screen...

I couldn't do factory reset because the phone wouldn't stay on long enough to do ANYTHING.
So as an update to this...
I was on my way to the closest store with samsung experience which is about an hour away from me and when I almost get there my phone RANDOMLY turns on...
I couldn't be more pissed and happy at the same time. So, obviously I try messing with it a bit and it shuts off again. This time I can get it to turn on after about 15 tries. Long enough for me to do a factory reset!
It lasted a good 30 minutes to an hour and it shut off again.
Hardware issue or is anyone else having this issue with 4.4.2 nc1?

Okay so I brought it by best buy and the guys couldn't flash it or do anything to it because it wouldn't turn on at all. They tried several batteries etc.
So, I decided to try the phone doctors and the guy thought it could be a malfunction in the power button because the phone tries to boot up any time you put the battery in. You don't have to hit any buttons and you can't insert the battery without it trying to power on.
I'll cross my fingers that's the problem and they phone doctor guy told me he has never seen this issue with an s4 but it was really common in s3's.
I go back in two hours to see if they have fixed it!

The s2 had this problem too and one way to confirm it was to pull the battery and put it back in. If it booted right away it was the power button. So it sounds like you're on to something.

My A1 "died" and i dont know why

Hello folks.
So I left my A1 charging at night, the alarm woke me up as usual in the morning. Just before leaving home I took it to check the time and then it was already "dead".
PS: The phone was never been knocked over, wet etc...
Symptoms:
- Black screen, as if was turned off / without battery;
- Buttons do not work;
- Doesn't react to any connections.
- Doesn't enters fastboot mod;
- It's not recognized by the computer;
- Also not charging.
Any help is welcome, best regards.

happened to me the other day on AEX, after flashing a kernel, turns out it does switch on but I had to press the power button for quite some time and then it switched off again upon minutes from switching on. I entered the recovery with the same method and installed another kernel, it works fine now

It's a possibility, but it's strange the phone has like 4 months of use, never had any problem.
I'm willing to try some stuff first, even open the phone to unplug and replug the battery on the mb.
Otherwise at my country (Brazil) Xiaomi has no warranty

I had this problem and it was just due to an loose flex cable. Try opening and reattaching them :good:

No problem, just two screws att the bortom and use the nails around the edge. Be careful not to break the plastic frame around the screen, it can be quite weak.

So yesterday a oppened the phone, disatached the flats and atatched then again, unfortunatelly didn't help =[.
We also made some tests and seems like it could be an issue with the battery seems like it's not charging nor receiving any charge.
Seems like the "regulator" of the battery or something like that is not working as it should.
I'm gonna try to test this a in a more acurate way, at least to be sure that it's the battery.

Probably on EDL mode. Try reflashing stock with MiFlash. Helped me once.

You can try make edl usb cable first, if not work then search mi a1 test point, you'll need to jump 2 point on motherboard with wire/pin.

The phone will power on without any battery attached at all, so remove it and see if you get life. If not, then it's not the battery.

So yesterday i tryed to make the phone enter at the EDL mode, by jumping the 2 points on the motherboard. Unfortunately the computer didn't recognized the phone at all, i'v tryed several times.
I'm starting to think that something related to the the motherboard just died.
I'll lend it to a tecnical that can fix it or at least confirm the death of the phone to me.

Just tested it yesterday, without success.
Even with the battery disconnected and ubs at computer or charger, the phone still not giving any signal of life.
Does it mean that it must be a serious problem?

Hello mate.
I'm sry for you phone, at my case i'm starting to believe that the mb/cpu died.
I was thinking that it could be the board at the bottom (ubs, mic jac) but i have been told that it's really rare this to happen.
Yesterday i tested the battery and it's fully charged, (so the battery isn't the problem)
I'm weeling to take it at the end of the week into a tec who can test all the hardware stuff in order to know what actually have failed.
Have u also tryed to engage ur phone at EDL Mode?

Hi.
Yep also tried shorting the test points, it does not respond to anything. Just totally dead.
Its sad cause i really loved that phone. I might buy a used cheap one with a broken screen and use its main board or other parts.
Thanks Knievel
