Won' t turn on! Tried all suggestions

Yes I have read all posts regarding "Screen Of Death" issue and i have tried all the suggestions. But still, my 10.1 won' t turn on. I have left it drain the bat for 2 days now.
Even if i plug it to the charger there is no sign of battery charging. Hence just blank black screen. any other idea before I have to go to the Service Center. Thanks. Any help would be appreciated.....

Connect the USB to a Windows computer and press Power + Volume Up for 30seconds. Do you hear a Windows "new hardware found" sound?

Thanks... Tried... Still fail. My PC only signaling found new hardware but fail the installation process. I guess because the tab is still not ON. Help....
It seems my PC recognizes the tab but can't find the driver. I can also feel "warm" near the power button area when i connect it to any electricity but still no TURN ON or BATTERY CHARGING INDICATION.

Have you tried to charge it with the wall charger for at least 2hrs and then unplug it and hold powerbutton 10 sec?

Actually, that is what I was expecting as result.
The Power + Volume Up enables the nvflash APX mode, the screen remains totally black. I simply wanted to know if the tablet works and the culprit is just the screen. From what you say, we get the expected results... Windows detects the new hardware so the tablet works.
Now try the opposite: Power + Volume Down, hold it for 30seconds.
If you don't see nothing on the screen, it is probably a screen contact that got lose... you need to service it by Samsung.

yes done that. Still not ON. When I plug it I can feel it is working since I can feel "the warm" but screen still is blank

Then you already know what to do.
No biggie, Samsung will send you a replacement for sure.

yes. In fact now the APX is still working trying to find " a new hardware ". Should I cancel it and try the POWER+VOL DOWN now?

Yes, go ahead.

DONE the Power + Volume Down still not ON. BTW the APX Could not find any driver? Is it normal. Before this happens in fact i can transfer any file with my PC through MTP. Thanks again for your help. Hopefully you still know any other solution.... Keep waiting

The APX driver is included into nvflash package, it does not matter if you install it or not at this point. The advantage of this test is that the APX mode keeps the screen off in purpose, while allowing you to flash the tablet through a CMD window (only if you have an unlocked bootloader). We used this trick to determine if the core of your tablet works... we wanted to isolate the problem related to your screen.
I recommend you to contact Samsung and have the tablet serviced. Some screens lose a contact point when you drop the tablet by accident or if a soldering point is weak... The heat generated inside is enough sometimes to sever a lose circuit connection. Either ways, you do NOT want to keep this tablet.
I hope you did not flashed the tablet with some custom ROM, or else Samsung might void your warranty.

OK. Then the only thing i can do is go to SC.......Hmmmmm I am still using stock rom but unfortunately i did root the tab already. Is it bad judgement??? Thanks anyway.
I really hope it is only the screen connection lose issue. But just for curiousity. If only the screen keeps OFF, does it mean I actually can still check that my gtalk on the tab still connects? How this thing works??? since i just check with my phone my gtalk on tab is off.

You ordered the tablet online from Samsung or you bought it from a retailer like Best Buy?

I bought it from retailer. BTW is there any kind of USB JIG for the tab similar to SGSII? I just thought maybe this can help solve the screen of death issue. Ha ha ha ....

Perfect, just go see the store and explain to them nicely the issue. I'm sure they will exchange it for you.
Forget about the JIG or anything else, your screen is gone wacko... What you do now is try to force a blind guy drive a car... Just go exchange the tablet.

Ok I' ll do that. Thanks for your info and help. Hopefully problem will be solved soon.

I had the same issue but I couldn't return to the store so I went through support. They don't have parts yet so they just send you a different unit. In total it took 2.5 weeks for me and I ended up with an unlocked unit

Damn, it took 2.5 weeks to get a new unit?

The good news is, it's recoverable. The bad news is, it's going to take a long time.
Keep it off the charger.
Hold down the power button to get it cycling through APX mode while plugged into your PC (can hear the USB connection sound in Windows).
Tape the power switch down, verify it's still going into APX mode after taped, then unplug it.
Leave the tablet alone for a few days. Think about puppies, chocolate, bouncing breasts, whatever makes you happy, and forget about the Tab.
Come back, plug it back into the PC, see if you still hear it connect. If so, walk away again, come back the next day.
When it finally stops going into APX mode, plug it into a wall charger and leave it alone for about an hour, it should start charging normally, and once it's got charge showing, it'll power up normally.
Rule of thumb is it'll take about a full day for every 10% of charge that was on the battery when it went down, if you keep the power button taped down.

Can anybody please try this

My power button just stopped working. It is all in and will not pop up, I tried to gently pick it up with a small tool but it won't come up. I am about 2 weeks out of warranty but still Ok as I have extended warranty from my AmEx. My problem is I am getting out of town for a week next week and will be dependent on the phone. It works fine except for the power button. So I am worried that if for some reason the phone powers down I won't be able to power it up without the power button. If I find a way to do that I should be good - I put a screen lock widget and can wake it up with the touch pad (hopefully it does not die on me too ). I found one post claiming that you can power up the phone with the wall charger and the home button but am afraid to try it - if it does not work I'll be stuck with a dead phone. So, can anybody please try this and write back whether it works:
if the mt4g is off, plug it into the wall charger, after you see the "charging" light and light in the optical pad, press and hold the "home" button for a few seconds (5-10) and the phone should boot into recovery just like that, at which point you can reboot from the recovery menu
Here's the link to the post - http://forum.xda-developers.com/showpost.php?p=11581315&postcount=17
I am unrooted on 2.3.4 with the latest OTA update (2.32.531.1) if that matters.
Thanks a lot!

I don't know, something might have broken or displaced inside, the key is down and seems stuck down. So, did you get to the bootloader? Could you restart from there? Thanks for the effort.

I tried it. I got nothing. Doesn't start with out the power button. You better get that out for repair or carry a charger and car charger at all times until then.

Darn, that's a bummer! Thanks.
I'm wondering could this be ROM dependent - work for some ROMs and not for others?

I also found one good MT4G to try it on and can confirm that it does not work.

Power button behaving funny on Focus ...

My samsung Focus is about 1.5 years old.. I plan to switch carriers at the end my of contract since AT&T is giving me lots of dropped call at the new place we moved to.. The phone is obviously out of warranty, so I am looking to see if I can fix it myself.
The power button on my Samsung focus is behaving very funny lately. When I hit the power button with the phone awake, it thinks I did a "long press" of the power button and shows me the shutdown pull-down image! If I pull-up the image, the phone still reboots...
If I press the power button when the phone screen is OFF, instead of turning on the phone, it again shows the pull-down image, and the same behavior ensues - regardless of what direction I pull the image in, it shuts down the phone.
Some things I have already tried:
I have tried a hard-reset (camera+volume+power, and format the device), but the behavior continues.
I have removed my SD Card (I am using the AT&T approved one), performed hard reset, and problem continues
I have tried a different battery (from my wife's focus), and problem continues
At this point, I am guessing that most likely, the power button connector is loose.. but I am not 100% sure.. Any suggestions on things to try?

Seems like the spring in the power button is gone. I suggest when you want to press it, lean the phone to the right (with the power button towards the ground) so when you press it, gravity helps popping it back.
Or replace the power button.

Any tips on where I can find a replacement power button and how I can replace it?

See my response here (and the thread referenced in my second reply). Seems to be one of the issues that appear in time... And in another case it was the battery...

I have ordered a new battery for now to see if it helps.. its a non-OEM battery off eBay.. Don't want to spend too much without knowing if that is indeed the problem..
I can't find a power button replacement part anywhere... I went over the video and the instructions to reach the power button housing does not seem very bad.. definitely do-able if I can find a replacement part..

The button itself is plastic (you can find some on ebay), and I don't know how it works, actually (If it's a spring or otherwise).
I suggest you watch a take apart guide and maybe, just maybe it's just dirt, which you can clean.
You'll know more and afterwards please share the result with us.

And now its completely gone... the power button won't respond at all.. the phone has been shut all day. If I take the battery out and put it back in, the SAMSUNG logo shows up for a few seconds and then the phone turns off again.. No way to turn it back ON using the power key..
I sat down to open the circuit yesterday only to realize that I don't have a #000 screwdriver... the smallest one I have is #00 which is too big for the 7 screws that hold the back panel
Off to Grainger today to see if I can find a 000 driver.. It can't get any worse now, so might as well open the phone!
Sure thing - I will update the post later with what I find...

You didn't say if the same happens with the wall charger connected.
Now, If you're going out, try and drop near a phone shop. Ask them if they can help you test with one of their batteries, either for a Focus i917 or from a Galaxy S i9000
Good luck mate.

Dang i thought i was the only one with this issue...
Mine started acting up about 3 weeks ago and it was seriously annoying especially when driving. I would press the lock button to change songs, but it thinks i did a long-press and does the "slide down to power off" thing. Even if i swipe up, the phone would switch off.
Then today, i take my phone out my pocket to send a text and find it's powered off. Won't even switch on now
Ender:
Plugging the phone in does NOTHING. The screen remains black.
Reinserting the battery causes the SAMSUNG logo to appear on-screen but again, goes black after 4-5 seconds.
Holding down the power/lock button has no effect, it's unresponsive.
I'm so pissed off this is happening 6 months before my contract is up. -_-

Don't know what else to say... I hope you still have warranty?

I've managed to get it into "download mode" now though, and my laptop recognises it as "SAMSUNG CDMA Technologies"... Huh?
---------- Post added at 05:02 PM ---------- Previous post was at 04:45 PM ----------
If i have it plugged into my laptop,
hold vol down, power, and camera while inserting the battery i get to the hard reset screen. But then that disappears in the same 4-5 second window.

Ok, it's working again... I left the battery out for a few hours (literaly about 3), then pressed hard on the power button, and placed it (the battery) back in the phone.
Let it turn on and then back off by itself, then pressed hard on the power button.
pressed the button normally, and it booted up no issues. So far works fine.
I expect this issue is partly the power button, and something else unknown

Yes' same thing with wall power. New battery arrived and did not help. Went to a local cellphone repair and the guy said main board needs replacement.. he suggested to buy another phone since repair will be more expensive.. he said that he needs to remove soldering on the board reinforce an auxillary power button battery and resolder it in.. no guarantees and will cost atleast $150

Lucky you!! This seems like a common problem with several Samsung phones based on a quick google search
Also bummed that this happened with 6 months remaining ...Now I am somewhat stuck since I want to switch from AT&T due to call issues with several months remaining.. and dont want to buy one till wp8 is out...

Just for fun... I am going to find a 000 screwdriver and try to re-jig the power button.. nothing to loose with the phone refusing to start anyway!

For what it's worth, my power button had been getting increasingly creaky over the course of the last few months, and although not sticking, was requiring ever more pressure to operate. Also, the sound of rusty bedsprings every time I went to use my phone was getting somewhat embarrassing.
I found the sturdiest piece of paper that I could wedge in between the button and the rest of the phone, put a bit of PB Blaster on the paper, and wedged the paper in. The button has since been as good as the day I took the phone out of the box for a couple of months now.
*Edit: Should probably mention that the paper isn't supposed to stay in there - it was just used to apply the lube without soaking the phone.

So its working completely fine now? No issues? I'll try that but im not hopeful.
I've been having the same issue, started yesterday. There appears to be no issues with the actual button itself, it doesnt appear to get stuck or anything to cause this, even without the external shell and just compressing the sensor itself.
walletless, you said that you tried reformatting it and everything? Damn. I was expecting it to be a software issue. I'll mess with the button mechanism a bit and see if theres anything weird with it

Phone is dead
re-jigging and cleaning around power button did not help.. I ended up ordering a chinese knock-off of HTC Note instead

Does any have this problem, but on a normal stock rom?
I was thinking it might be just custom roms, I don't think that would have anything to do with it
Its worth a shot though

My phone died last month. I only installed updates that came through Zune up to 7.5. I went into AT&T and they told me too bad because it was out of warranty. I called Samsung, and they wanted me to 'volume down, camera, power' reset my phone, which didn't work. Samsung told me to send it to them for $70 because I was out of warranty.
Instead I entered a developer competition for a Lumia 800 and won. Now I just have a dead focus, and a new 800. I'd still be interested if anyone finds out a way to fix the focus problem.

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.

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.

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.

Bricked Le Pro 3 727 (Blue Screen of Death)

Hello friends,
My LeEco Le Pro3 (727) bricked two days ago and I haven't had any luck turning it back on. It was running LineageOS 8.1 latest official build with an unlocked bootloader, Magisk 16.0, TWRP 3.2.1, and OpenGapps ARM64 8.1 nano. Immediately prior to bricking I was setting it up for bluetooth with my car and was trying to run Google Maps through voice command. As I directed Google Maps to take me to a location, the phone froze, the screen got all "fuzzy" and I got the dreaded blue screen of death.
From that point on I have not been able to turn the phone back on. When I press the power button it will vibrate every 5-10 seconds as though it will turn on but it never does. Ive tried everything I can think of to get to work again including:
- Pressing power button for 2 min, 5 mins, 10 mins
- Pressing power button + vol up (recovery) for 2 min, 5 mins, 10 mins
- Pressing power button + vol down (fastboot) for 2 min, 5 mins, 10 mins
- Pressing power button + vol up + vol down (QFIL MODE) -> Installing Qualcomm driver, downloading "FlashOne2.0", flashing all versions of "qfil files" that I could find but still unable to boot up
- Pressing all different button combinations while plugged in to computer/charger
- Using different cords/chargers/usb ports
- Leaving it to charge overnight/full day then trying to boot up
- Leaving it sitting not charging for a full day then trying to boot up
At this point I'm starting to think it might be a hardware issue but who knows..
Any advice/suggestions would be greatly appreciated.
Thank you.

Where did you buy it from.
I don't have much to add here it seems like you have done everything that you could
Let's clear this up no fashboot right.
Only one thing to try hold power down then plug in USB.

Thank you for the reply.
It was purchased from a local retailer here in the United States through Google Express. Fortunately I should still be able to return it for a full refund but I would rather have a working phone than my money back.
No flashboot either. It's like the phone just decided to quit working one day. Tried holding power while plugging in USB as well and no change.

The conclusion I'm reaching at this point too. I'll see what the return policy.

Well if it will not turn on it is hardware issue you should be able to return it.

That is so strange. The screen going fuzzy like that is indicative of a hardware issue, IMO. I saw that on my laptop once, but that was because I hit the screen too hard. Never seen a BSOD on an Android device before. TIL.
I assume you've already tried an adb logcat. Were you using the original LeEco cable? I heard it has issues since it's not up to spec. 99% hardware failure, but I can't help but think it has something to do with driver communication confusing the device and causing hardware failure (?) if that's even possible.

Just a final update for those curious.
After leaving the phone alone for two days I plugged it into the charger and low and behold it started vibrating and booted up by itself. It was running a Chinese developers editions 720 rom due to the QFIL File I had flashed in my earlier in my attempt to fix it. Battery was drained so I let it charge for a while and everything was fine until I attempted to restart the phone. As the boot animation was loading, I got the blue screen of death for a second time.
I took a quick picture, the phone shut off itself off, and same as before it wouldn't boot again. As other users have suggested it appears to be a hardware issue, likely with the motherboard. Fortunately I was still able to return the phone (purchased through Google Express via a local retailer) and received a full refund. I've since bought another Le Pro3 (727) and hopefully when that one comes in, it won't have any issues.
Thanks to all the users who left suggestions/tips.

You bought the same phone again? :good: You're courageous, lol.

i been experiencing the exact problem like your on my x720, as i boot up the system or enterting the recovery mode the screen go fuzzy on loading screen and shut itself off completly, i can still able access fastboot. As i left it for a while the phone will be able to almost finish the boot then ending it all with a blue screen.
Have anyone found a way to fix this DIY since my phone has past the guarantee plan ?
