Help! My Galaxy Note 3 N9005 Won't Turn On

Hi Everyone! I have a galaxy note 3 SM N9005 32GB. I've started facing a very weird problem recently that I cannot find described anywhere in quite the way I'm experiencing it.. My note 3 powered off by itself after running out of charge last night. Ever since then, the only thing that happens when I plug it in to charge is that the screen stays black and the phone only vibrates once. No charging LED indicator, nothing on the screen at all, just a black screen like when the phone is off. In order to get it to vibrate again, I have to do a power drain before connecting it back to a charger. There's nothing on the screen at all. Can't boot into recovery or download modes and it's not detected by a computer. Have tried multiple cables (USB 3.0 and 2) and have 2 batteries which were working fine till this happened.
Any idea of what's going on? And if I can back up any data from it like contacts and messages? Thankfully, I had transferred almost every app I could to the micro SD card (128GB Sandisk) and was able to at least recover my notes from colornote, but I digress. What is going on in my phone?
Additional info - the battery is probably still charging when I plug it in. I think this because the phone and the battery warm up after being plugged in for a little while just like they used to when the phone was working.
Even more additional info - I don't know if this is relevant, but I recently upgraded to the most recent OS version available. I think It's a 5.0 or something but I can't remember exactly. Also, the front camera stopped working some time after the upgrade. And 2 days before this, 2 apps refused to update for some reason. I don't know if this could be related.
TL;DR - Note 3 N9005 ran out of charge and is now almost dead with black screen and no LED but vibrates only once after plugging in or pushing the power button. To get it to vibrate again, a power drain needs to be done. The battery is still charging because it gets warm when plugged in.

I too had the same problem but when I connected the phone it would not even vibrate like completely dead.
Maybe try these:-
1)Connect it to the pc of it detects it then recovery would be easy.
2)Connect the charger properly.
3)remove battery for like 30 minutes and try the steps 1 and 2 again.
4) If still not working go to the dealer cause I had to go to him too. ?

I bought it off of amazon, any suggestions in such a case? Besides trying to send it back, I mean. Anything or tool I can try? I don't mind if it gets technical. Need to get my app data off the internal memory.

Though mine started with a different problem than yours, since today it seems like the problem is same like yours. Phone's display is totally black, yet I can go to download mode (cause phone is detected by Odin), I flashed the latest stock ROM of UK too, but now there is no change anyway. I want to be practical and think that this is a display problem, if not I will be more than happy. I have to send the phone to a local technician I know, lets see.
The only think I believe you can do is wait, for maybe 6-7 hours or so, with the battery detached, and then insert it back and see whether its booting with display on or not, if not its more likely a hardware issue, display possibly.

[SGH-I337 AT&T] Unmodified, Stock SGS4 boot loops, freezes, graphical bugs HELP!

Hello everyone!
My parents contacted me asking for help with some phone issues that I thought would be minor but this is now something I have to submit to you guys because I just don't know how to tackle this issue;
I've got an unmodified, completely stock AT&T Samsung Galaxy S4 that has been owned since launch. My parents were initially complaining about how the phone stopped charging and wouldn't turn on. I thought, "Easy, dead battery, it's been 3 years so how could it not? It might not be delivering enough voltage for the SoC..." but i'm not sure that's the full story which is why I want your guys' opinion since this place is a wealth of knowledge.
Things that are known:
When you charge the phone, the basic "battery charging indicator" that is shown when Android is not booted into or powered on freezes, or sometimes does not detect a battery so does not even turn on. Doing battery pulls seems to change how the phone responds. This is what my parents were experiencing. I thought, either dead battery, dead micro-USB cable, AC adapter, or charging circuit within the phone. Since this was obviously a big job, I took the phone back home for this weekend to play with and now this is what i'm experiencing.
So I got the phone to charge using one of my AC adapters for some reason, despite using the supposed broken charging cable to transfer data successfully without corruption using my own phone (LG G2) to confirm if it was just the cable. So now the SGS4 has a battery that is 100% charged, I turn on the phone and tried various methods to get the phone to boot successfully back into android. The first obvious one was to boot into safe mode using PWR, letting go of PWR, and then pressing VOL UP. It booted ONCE or TWICE successfully into safe mode into android, it shut off after 5 seconds being into the system due to low battery. This was BEFORE I was able to successfully charge the battery to 100% with my AC adapter but has failed to boot since.
Now since I've been failing to get into safe mode as when I boot the phone up, the phone freezes or has graphical glitches at the Samsung post/splash logo as seen here:
After some desperation, I considered using KIES/Odin to reflash, but mostly I tried going into download mode to see if the phone would even go into it by doing PWR + VOL DOWN. It did get into download mode but it froze/restarted forcing a battery pull and ever since then I keep getting occasional error messages such as "System software not authorized by AT&T has been found on your phone.", or this screen with a Samsung logo and an open padlock. I notice sometimes that when I'm at this open padlock screen, it sometimes begins to boot into the system but quickly freezes when it plays the boot jingle:
At any rate, I ordered a new battery but I fear this might be EMMC corruption or just something I don't quite understand. The phone has valuable information that I have to recover despite my parents CANCELLING a backup of the phone, they failed to heed my due diligence and are now freaking out about the data (photos, contacts, etc). I just need the phone to boot so I can make a nandroid backup, export the contacts, transfer media off the phone and wipe this thing and start anew. However i've already let them know that it might not be possible. The most important thing is to get this thing out of this soft-brick?
Please help because I have no idea where to steer this ship from here on out aside from waiting to receive that new battery and hope these instability issues are caused by low voltage. I had an SGS2 which had the crazy EMMC bug so I'm hoping its not EMMC corruption.
Thanks for your time everyone! I'll update this thread to reflect new information as I play around with the phone.
Edit: Here is a video, I go through a lot of the same information posted in this thread but here it is.

Possible loose connection inside the phone? Was the phone every bumped, dropped, or exposed to moisture?

Not that I know of. I'm going to check the water damage stickers if I can to ensure that's not the case but i've been told it was sudden. It had been dropped once before but had been working fine for quite some time up until recently.

Maybe the effects of the drop and manifesting themselves now?

Samsung S4 VE I9515 wont turn on

Hello,
So let me give you a brief so you'd know everything - a few days ago, I'm gonna call it day 1, I walked under light rain with the phone in my pocket, it worked until the night of
Day 2 - started to lag a bit, it was like I was running some heavy apps and like the ram was insufficient. Restarted the phone, everything seemed normal.
Day 3 - Phone went off while was browsing. So I have to make a note here. I was running cm13 with android m and twrp 2..something and there were occasional reboots by itself rarely prior to Day 1. Also, I was using a supercharger (or whatever it is called, it is a charger that charges faster) for about a month.
So when the phone went off while I was browsing, it started by itself and stuck on the android loading. I restarted, cleared dalvik and regular cache - still stuck on boot. Flashed many times, changed the recovery to twrp, and still was stuck on rebooting and occasionally it didn't turn on. There were random occurrences of errors on flashing roms, which never happened before (for example, "cant mount system or data"). Within the time passing by, the phone started not to turn on when I tried to. By this time rarely got stuck on the first boot screen saying with the text "Samsung S4". Yesterday, Day 4, the phone never turned on, except one time. I don't remember doing anything special. I just pressed and held the power button and it turned on, but went off shortly after the android boot animation appeared.
Also there was times on Day 3, when I was trying to boot into the system, it got stuck on the android booting animation.
On and prior to Day 3, while I was charging, whenever it is on or off - I had the indicator light for charging. Now when I plug it in to charge - nothing happens.
To skip any unnecessary questions, I will make a short QA.
Q: Did you tried to boot into recovery/bootloader?
A: yes, nothing happens
Q: Any sign of life on adb while connected to a pc??
A: no
Q: Is battery dead?
A: I don't think so, but actually I'm not that sure. When I connect a separate led light to it, the led lights up Whatever, if it was a faulty battery when I plug the phone on the charger, it should've worked fine.
Q: Why don't you just buy a new phone?
A: I was planning to buy a new one, but after just 4 months when I have to renew my contract. I don't want to buy a phone off contract.
Q: Are you stupid, if you can't manage to fix it by yourself, why don't you give it to a repair?
A: I truly believe that the professionalism of repairers doesn't exist in my country via old experiences with them.
So in the worst scenario I will loose time by trying to fixing it and for 4 months I will use my old android phone.
In the best scenario, my almost 2 years old phone will revive.
Also, I have a multimeter - I can check the electricity. Just tell me what to check.
Thanks.

Probabily the rain damaged a part of your hardware. Did you solve?

If the battery is dead, the phone won't work.
The battery needs to have at least a bit of charge in order for the device to work, even if it is plugged in.
If the battery can't hold the charge, and the device uses more power than it gets, it turns off. I speak from experience.
These devices don't seem to work without a battery. Power goes to the battery, and the phone takes the power from there. Power doesn't go straight to the phone.
Anyway, I don't think a bit of light rain hurts the devices, especially if it was in your pocket. I walked through rain with my device in the pocket many times and no problem.
It looks to me that the hardware is failing. I don't believe that a faulty battery can cause a bootloop. I also don't believe that the power button causes a bootloop.
What I suggest would be:
1) Try going back to stock ROM.
2) Maybe try to get an S4 with a broken screen and switch the motherboards.

Samsung Galaxy S7 Edge Not Turning On

Hi people.
So i'm having a problem with my S7 Edge and i don't think it is common. A few weeks back I was using my phone and it would suddenly turn off and the battery would be drained too. After this first incident with the problem it happened more often, and the phone would start doing boot loops to the point where the phone just froze and turned off. When these problems occured it will usually need to be a problem where I do a safe boot (Volume up, Home button and power key), and everything will be fine (or to charge it if the battery drained), but recently, the phone just didn't work at all, to the point I waited for the battery to drain (10 hours), and try charging it, nothing happens.
So firstly I was watching a video and checking my CPU/Battery tempretures to see if that was the problem (the tempretures at the time were around 31 degrees), and mid way through the video it bugged out through the audio in a high screech and turned itself off.
I tried turning it on again but no response to the screen, i tried safe booting it, or every alternative booting option, it did not work at all.
Here is all the diagnostics and repairs I did, but no luck:
- Tried turning it on
- Different boot options (Volume up/down, Home button & power key)
- Cleaning the port for moisture detection
- Replacing the battery for a new one (Genuine one)
- Doing all of the above, with it on charge
- Connecting to a PC, but no detection
One positive I found was that when i put the phone on a wireless station, it would change colour to show that the phone is charging. I have however took the wireless out of the phone as it was in the way of the battery, and safely in my draw.
Before this final fault happened, I did do a recovery to a previous Android version, just incase if it was a software fault, but it wasn't. The phone is not rooted and I had it since September of 2016.
Is there any alternative options to do? As i'm running out of ideas to do as every solution on the internet is to turn it on, which i can't whatsoever.
The warranty is voided also as there is a crack on the screen lens, and it's way too much to pay for a repair.
I need some explination of why this is happening, so I can go in the right direction and not to waste money if i was going to a repair service, or purchasing the parts for myself.
Any help would be highly appericiated.

Check your installed apps to see if there any viruses on your phone. All you said are signs that your phone might have a virus (check how to remove it here: https://www.unlockunit.com/blog/how-to-tell-if-your-phone-has-a-virus/
However, there is a chance that you do not have any viruses on your phone, but at least you have to isolate this possibility.
Did you recall installing any app prior to this behavior?

This may be the case, however i can't turn on the phone at all. I tried every possible reboot possible, download mode, bios mode, safe boot, reboot, but nothing happens unfortunately. Unless i can do it whilst it is turned off, i can do something. I have a PC if i can do anything else with it.
I don't think I have installed any weird apps on the phone.

sounds like a brick to me. Not a lot I can thing of you can do.
If you place the wireless card back in does it boot?
IT sounds like you've messed with the internals, so possible you damaged something?

I don't particularly think that I broke it from the inside as it was behaving the same before i opened it. And when i used the wireless charging, it will only indicate it was charging or getting detected on that charging pad and not on the phone regarding a red led, or the charging icon

Have you tried holding volume down + home + power for 15 seconds and try turning on the phone again?

As mentioned in the description, I have unfortunately

Essential Phone keeps powering off

Hello everyone my brother's Ph-1 keeps shutting down right after powering up, I have tried everything from factory resetting to trying a different charger, nothing seems to work. This happened after he didn't use the phone for almost a month, it worked perfectly before.
It powers off even when on charge or connected to the laptop.
The phone doesn't stay on for more than a minute or two which means i cannot use ADB to side load an update
The phone is running Android P and the April security update patch.
Please do help me out
Thanking you

It could be corrupted though it sounds a bit like a battery issue, to me. If battery discharges too much eg it didn't shut down itself properly when battery was at a low level (they retain more charge than shown to user so it can shut down with proper procedure) & the battery ran down past it's reserve the battery may not be able to be recharged with a normal charger even though you charge it. (Thought a battery specialist could possibly revive it with a boost charge, though I've only seen these used with industrial batteries)
with a "dead battery bootloop" sometimes you can get it going by booting when connected to the charger, but you'll probably need a new battery. Maybe also try boot into safe or recovery mode when connected to Essential charger. (I'm assuming your phone not corrupted, though as you haven't given us much info about exactly what happens & what you are seeing)

The phone shuts down even when in recovery or safe mode whilst connected to the charger.
It does sometimes fully boot up and then shutdowns, but mostly shuts down while still on the essential logo.
If I may ask what do you mean by the phone might be corrupt?
Can one month of non usage cause the battery to die out?

by corrupt I mean some data that is part of the boot process causes bootloop so it shuts down, but as your phone is shutting down at different points in boot cycle I think it's probably battery
Leaving the phone turned off unused for longish periods should not be a problem normally even with a few % left in battery. And even if left turned on it should shut itself down when battery low & be able to boot up again after a month due to the battery "reserve" capacity (but possibly a month was too long). And if it was not recharged straight away and/or rebooted multiple times the battery "reserve" could fall too low and not have enough power to start/shutdown properly (possibly causing data corruption ... though l don't know if there is some sort of fail-safe boot procedure ) Then there is a possibility there is a hardware fault with battery/phone that meant battery lost too much power.
There were some tricks ie "boost charge" you could do with removable batteries that were in "deep sleep" as shown here for example
https://m.youtube.com/watch?v=TEXA7qIJ968
But they don't really work without taking your battery out (for us we might as well get a new battery when opening phone up, & there would be some risk that you damage battery as we do not know the exact charge to apply on this battery, which could cause unsafe battery) I wouldn't want to freeze my phone even though it should survive OK, as I'd be alittle concerned about long term effect on our screens small pixels (I remember the guys at popular mechanics put an old flip phone with little LCD screen in liquid nitrogen & it still worked after being warmed up!).
See https://batteryuniversity.com/learn/article/low_voltage_cut_off
for more tech details

firmware issues do not cause the issue you are describing
you have a hardware problem
sounds like a bad battery to me
good news is the battery is not difficult to replace (don't listen to ifixit I am not sure what they where smoking when they did there tear down)
https://www.youtube.com/watch?v=BCKxAQXdTJ8
don't bother with silly and wrong tricks like trying to hack the battery back to life its the wrong way todo
if the battery ever gets to that point then the battery is bad enough said

So true! )) As much as I respect the guys from iFixit, they screwed this one up pretty badly - basically, made a tutorial on how to destroy your phone. Fixez.com did much better.
