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.

kindle fire refuses to boot.

I installed cyanogen and TWRP on my fire a couple days ago. It was working fine but today i was playing a game boy emulator and it shut off on me. the battery was completely dead at the time (i was playing plugged into a wall, and it had been totally dead for about half an hour) so i figured i just bumped the cable or something, the problem is it won't charge. when i plug it in to a wall, PC, what have you. it boots to the fire logo and asks me to press power to enter recovery (as it should) but then it just turns off and shows the same screen. i left it alone for an hour and it was still doing this. when i try to power on without being plugged in absolutely nothing happens. I've tried my usb cord and two different chargers, all of which work with my phone perfectly.
i think this is a hardware issue(please tell me otherwise) which would suck because I'm pretty sure everything i did voided my warranty. any suggestions or am i just boned?

well i contacted customer support and they didn't seem to care at all about the root, they told me it was a battery issue and are sending me a new one. good news for anyone wondering if rooting voided warranties, it doesn't.

That's great to hear that Amazon isn't going to be a **** about it. It is one thing if someone screws it up because they rooted but a hardware issue is a hardware issue and it is a good sign that they are not looking to screw you merely because you happened to have rooted coincidentally to having gotten a dud unit.

this same thing happened to me it seems. I was playing a game and my KF died. so I charged it for awhile but now its in the same type of weird loop, just like yours. Even after successfully issuing commands to change the bootmode etc, which I can only do like 1% of the time since it keeps rebooting. Hope its not a hardware issue though

it is a hardware issue, at least thats what amazon said. i fixed mine yesterday though, plug it in wait for the loop BS to start and hold the power button until it stops completely, then wait about 20 seconds release and press the power button again. I've had to do this twice today too, so definitely get a new one sent out, but it works for now.

I wonder how friendly Amazon will be after replacing a few thousand of these because people are screwing them up???
Seriously haven't seen this many "help I bricked my device" threads ever in a forum.

There are a lot of "I bricked my device" threads but the vast majority are having driver issues or stuck in the wrong boot mode. Almost everyone I have seen posting with a problem gets it sorted out and has their Kindle Fire working again.
The OP here appears to have a genuine hardware problem, according to Amazon, and didn't "screw anything up".

Hi,
For those who have problem with lag:
From Stweaks, change default gov to Lionheart, gpu gov to simple, I/O to fiops, disable android logger, enable zram, reboot.
These settings also give me great batt life

so i made the changes and it did make a big difference. i shut the phone down 2 hours after to charge it,, and thats when a odd thing happened.
its dead.
no life at all. even when its connected to my pc. if i plug the charger in it just gets hot.....thats it.
can i assume its bricked for some odd reason??

what happens if you pull the battery, plug it back in and try and reboot into recovery/download mode?

i did that + charger,and lead.
no responce and all. if i plug in the charger the top half of the phone gets quite hot in the main board area.
im sure some people come on hear with problems with out telling the full storey ( dropping it down the toilet,or just dropping it) but i literally shut it down to charge it quicker.
im still scratching my head over this.
if all else fails i may look into buying one with a smashed screen on ebay and replace the main board as my phone is in great condition,....gutted.

it does sound like a hardware issue - can you take it back to a samsung service center?

i could...... but it would cost much more than its worth.
iv had it from new, such a shame.

If you tried another working battery, tried connecting to a computer and cant get into Download Mode.... I say your phone is dead and it sounds like a hardware fault. I have seen soft bricked and hard bricked phones, they still show some form of life like the led turning on, pixel salad, black screen (as you can see the screen light up), white screen, cant get into recovery but can get into Download mode and etc.
Sounds like its dead but I am sure its got nothing to do with what you did and its just a coincident that it died.

Phone suddenly hard-bricked. No recent flashing.

Hi everybody,
What Happened:
My phone has suddenly become totally unresponsive. I have been using it most of the day, it was sitting at around 70% the time that it happened, but it is now a totally black screen. I had just taken it out of my pocket and it was suddenly like this.
The only idea I could come up with as to why this happened is that I charged it off of a JBL Charge 2 last night. I'm not sure if that may have messed with the battery, but I do find it odd that it's totally unresponsive while plugged in.
I was running android 7.1.1 DP2, with the ElementalX kernel 4.0 I believe. I was also rooted with SuperSU. What's really odd is that I hadn't done anything new recently besides install uTorrent and VLC media player. Otherwise, my routine has not changed one bit. Up to when the phone actually died, I hadn't even used either of these new apps the entire day.
What I've Tried:
I have tried plugging it in via AC, via USB, I've tried booting into recovery or fastboot, but there is zero response from the phone. No indicators on the screen, no LED blinks, no vibrations, nothing.
What I'll Try:
If anyone has any experience with this happening, I could use some advice. Otherwise I'm just going to wait it out, consider an RMA I guess. However, my device did have the bootloader unlocked and was rooted, so.... I hope it comes back by itself.

My advice is to keep it plugged in, or see if there is a response on the computer perhaps on fastboot, upon using the bootloader keys. I haven't had this, just a few suggestions. Good luck!
PS: A RMA will probably be needed, there are much more experienced people around here. Sure you may get replies later.

Good luck?problem all nexus 6p!!! Lg responds repay helps, hawuei what to do? problem arises with nogaut not be our fault, how to fix this? My phone now in service but to be fair this? warranty and having to wait ..

Is my Note 4 dead?

Hello dear community,
I'm posting there because I have some doubts about my phone and i'd like some answers from you.
1 month ago, I was charging my phone. When it reached 100% battery, It was fine but the problem is when I was trying to press "power" to turn it on but It didn't want to. So, I removed the battery because I couldn't even turn it off. When I tried to restart it again, it didn't want to. No reaction to the "power" button.
I followed EVERY tips on Google but none worked. I also tried to change my battery but nothing. I tried also to connect it to my computer, it was detected but my phone didn't turn on.
So, I guess my phone is dead unless if there is a solution to make it working? Also before that, my phone was becoming very laggy and when it had a small lag, it was turning off and was rebooting.
Thank you in advance for your answers.

I have mustered some conclusions about your phone based on what you typed:
1st claim: The power button no longer works anymore
•Reason: "... when I was trying to press "power" to turn it on... it didn't want to... When I tried to restart it again, it didn't want to. No reaction to the "power" button."
—Seems like you're gonna have to find another Note 4 and replace its motherboard with the Note 4 whose power button doesn't work anymore after 5 years.
But before spending, I would like you to try this method from a Youtube comment:
"... you'll just have to keep the charger [cable connected] on [your phone] while you take off the battery, and put it back after; then, remove the charger quickly..."
—————
2nd claim: The screen no longer works
•Reason: "I tried also to connect it to my computer, it was detected but my phone didn't turn on."
—If the phone is charged, seeing nothing but blackness, but you still see an emitting LED light on the top-left corner, that's a sign that it still works, just not the screen. So I would suggest that you buy a new screen and replace it with your old one. If you think you can't, then go to a phone repair shop and let others do the repairing.
—————
3rd claim: The motherboard is dead
•Reason: "... before that, my phone was becoming very laggy and when it had a small lag, it was turning off and was rebooting."
—The motherboard might be dead if these are happening, but I don't think this is the right reason unless the first two conclusions are proven to be true. If the first two conclusions are proven to be false, then the motherboard is dead, and you may either buy another Note 4 motherboard or get a new phone.

Thank you for your answer.
To answer you clearly about all the points you clarified, there is no led light appearing when putting it on charge and I also tried the "Youtube comment" but nothing.
So I think, the motherboard is dead as you mentioned. I just don't understand how it died after a charge but as I saw on Google, it's a general problem on Galaxy Note 4, so I think i'm not surprised at all. It's been since 2015 I had it.
Thank you for your time and to have solved my doubts about the death about my phone.

Put in cold fridge for 30 min without battery, then try to turn it on. If not, try the cardboard method under the emmc chip (search youtube)

Is this a serious thing ? (fridge)

I did the oven trick on my n910t. I left my phone stuck in the grill of my truck when I changed the brakes. I took it for a test drive and ended up running over the phone. Me being a noob at the time didn't know the AT&T Note 4 would not unlock Bootloader for custom roms or custom recoveries. I purchased the AT&T Note and was sorely disappointed there after. Flash 2019 I still have the motherboard for my note that I ran over. I can only get in to go into download mode and only when it was plugged in. I flash custom ROM or custom recovery and it would say would pass but it would just boot loop and boot loop. So I read somewhere where you can put it in the oven for around 5 to 6 minutes at about 200° and that it would settle any of the cracked solder that be around the emmc or anywhere else on the board. So I tried it. I stuck it in two different times at five minutes a piece, pull the board out and let it set for a day. I installed the board just a little while ago and she fired right up. It's amazing

I've recently replaced the motherboard on my N910F with a used one bought from AliExpress. As it's used I've no idea how long it will last but for £30 was worth a try.
It was pretty straightforward replacing the motherboard using one of the tear down guides on YouTube.
