T-mobile Note4 N910T3 Weird issue - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

Hello to everyone
I have a very weird issue with my T-mobile Note 4 SM-910T3.
Ive had this phone for like 4 years now. I had many custom ROMS on it with the very last one being Project L N7 with Note 7 features by Lanc-City. Let me note that this ROM had many bugs nevertheless I liked it for its features.
Now let me get right to the point:
My battery is original and yes it is old, my phone would turn off/restart on about a 45% charge then about 20% again and 15% would be the lowest and I'd have to charge it.
I believe I had about 30-35% of battery left and I had my flashlight on (torch) and forgot about it being on in my pocket for like 10 minutes.
When I got back home I noticed the flashlight was still on so I tried to turn it off and immediately my phone went dead.
Since then my N910T3 only turns onwhen plugged into power through its usb port/charger.
When it's plugged in, the battery charging icon with the lightning bolt shows up after some time and either stays on with no percentage or the phone just keeps bootlooping on & off into the battery and it does not charge at all.
The phone will not boot into android at all.
Initially I tried a few different batteries but to no avail.
So I go into TWRP recovery, cleared dalvik cache, full factory reset and all other stuff and for a minute I thought my phone is back up and running with the choose your language screen of the Project L N7 but right when I tried to choose the language my phone turned off.
After this incident I'm unable to get into recovery, doesn't show "recovery booting.. "and it won't boot into recovery mode at all.
So now I try Download mode and it still works but not completely, phone does not show up in ODIN or in Samsung KIES or in device manager.
I did install fresh Samsung drivers, then did fresh KIES install but no luck
I'm unable to do emergency factory reset through KIES or any other way such as through recovery from micro SD card.
My mum has a T-mobile SM-N910T (take note; mine is the N910T3, so a little updated revision) and hers shows up immediately on ODIN & KIES with no problems.
I love this phone and in my opinion the new note8 isn't much of an upgrade but I still like it however I'll wait until the Note9 comes out and see how refined and updated it is because of the tick-tock upgrade cycle whereas the tock is a much more refined version of the tick (take for example Intel processors tick tock cycle and you know what I mean)
If you're able to help me, please do so.
Kind regards,
God bless.

I have the I9000 . Until this morning I haven't had any problems with my phone. I was on C-ROM KK 5.8 (not that it affects my problem) and last night I left my phone to recharge. This morning I've unplugged my phone from the wall charger and made a reboot (my morning routine). Strange thing happened. The phone went into the phone off connected to wall charger screen mode but showing that the battery is empty. I took my battery out and now every time I place it back in my phone, the screen goes on showing empty battery or it's checking for battery level, without even touching any buttons. If I try to go from that screen to make my phone boot using the power button it does not react. I can't go in recovery mode , only I can go into Download Mode from that screen. I went back to 2.3.6 JVU using Odin and rooted it, phone booted fine. Now the thing is : When I am turning off my phone the phone keeps doing that battery screen problem. It turns screen on, acts like it's in a wall charger or it's checking for battery level or something and keep showing me an empty battery for a second then the screen goes off and back on again and only way to make my phone usable is to flash using Odin , the 2.3.6 stock ROM again and not take my battery out. If I try to flash CM 11, it goes into a recovery loop (because it's changing partitions sizes and the recovery version) and I have to take my battery out and it does it again. If I turn my phone off, my phone does it again and only way to boot it is to flash something from Odin so it forces it to boot.
Please Help ! What could be the problem and it's there a way to fix it?
Edit: I've been using my phone for an hour with on the Stock 2.3.6 and the battery level dropped just a bit . So The battery is not draining completely, and that fast. Also I've tried with a different battery and the problem persists. And my battery works just fine on a friend's GT-I9000. I've also successfully flashed Mackay CM9 2014 1.7, the situation didn't change. Also tried with Samsung 2.3.6 JW4

Two questions for clarification:
-Do the symptoms differ depending on whether you run stock or custom ROM? Or symptoms are 100% identical?
-If you shutdown your phone, keep the battery in position and do not connect the phone to the charger, it still shows the battery-crazy stuff? Because that would lead me to believe it is a hardware thing....
If there is a difference between stock & custom:
Maybe the hardware is dealt with differently between stock & custom ROMs making it look different, but I am not sure about that. You could try whether CM7 has the problem as well, as that one had a kernel that was much closer to stock.

Thank you for replying.
1. it's 100% identical on stock and custom ROMs only the battery icon shape is changed but the problem is the same.
2. The screen turns on by itself, without being plugged to anything.
3. Just tried CM7 and it's the same.
This is what is displayed when I put the battery and the phone is turned off, without being connected to anything. The picture is an example, found on the net, I don't have a camera to take a photo of my phone but the image shows exactly what I see for a second then it turns the screen off and back on forever, phone reacts only to download mode.

I'm afraid this may be hardware related if the symptoms occur on different types of ROMs. The charging animation with screen off is triggered by the charging hardware of the phone, which thus seems to give wrong signals...

Thank you for your help and clearing it for me that it is not a software issue. Guess you are right it's a hardware problem probably caused by the wall charger, after 2 years of usage I think it starts to break and "took something from the phone with it as a heads up" . I have to make a visit to the "phone doctor".

Galaxy S5 (AT&T) Won't Power On - Tried Multiple Good Batteries - Tried 3 Button

Asking for a second opinion before pronouncing the patient dead.
Last night my wife handed me her Galaxy S5 and said that it was hot to the touch (and it clearly was). I pulled the back and the battery to let it cool for about 30 minutes. After that, I tried to power it back on, but it was in a boot loop. I pulled the battery again, reinserted it and let it charge overnight. This morning she woke me to show me that her phone was at the OS download screen. She said that she had pressed Power and Home to boot it up and that it went to the OS download screen on its own. She denies having pressed VOL-Down (or VOL-Up) when she powered it on.
This was followed by it being an endless boot-loop. Anyway, after all this, I thought that I'd reflash the kernal and start over. However, after another battery pull, I can't get it to turn on. I swapped the battery in her S5 with a fully charged battery from our daughter's S5, but wife's S5 still wouldn't power on. I tried wife's battery (strangely only 52% charged after being on charger all night) in daughter's phone and it booted right up. So... battery is not the issue. Further troubleshooting this morning, I tried the three-button-salute (holding power, VOL-Down and Home button) until I thought I'd need finger surgery, but nothing. I installed Odin and connected wife's phone to my PC. For an instant Odin seemed to recognize the device, then nothing. Subsequent restarts of Odin never recognize that there's a phone connected. I installed KIES, but it doesn't see anything connected. My PC's USB "safe eject" thingy does not see a device connected.
Her phone seems (to me) well and truly dead. I'm out of ideas for troubleshooting (much less fixing) this device. Any suggestions before we have a memorial service and bury it in the backyard?
A Few Questions
The mention of odin's temporary recognition leads me to believe it isn't completely dead.
1. What was the version of android (4.4.4, 5.0, 5.1)?
2. Are the samsung drivers installed properly on your pc?
3. Did you use the oem cable or a good build quality data cable?

It was at least 5.x. It was whatever AT&T had given as far as OTA updates goes. It had never been rooted. It would have taken any OTAs that AT&T ever issued. Sorry, not my phone, so I'm not sure.

There were no error messages of any kind when installing KIES 3.2.16011_2 (which would have installed/updated Samsung drivers).

I used a high quality cable from MonoPrice. I've used the same cable countless times for flawless data transfers between my PC and various family Android devices.
Dupe, sorry.

Note 4 turned off and won't turn back on. Bricked?

I flashed CM 12.1 a while ago and it would sometimes freeze up so I would pull the battery if vol down + power didn't work (which it usually didn't) and then last night it just turned off and never came back on. Sometimes it would boot into download mode and say "failed to do normal boot mmc_read failure" and others it would boot back up no problem. Now I can't get it to boot into Recovery or Download, I've taken the battery out and help down power for a while, then put it back in and help power for a while, tried charging with two cables that both charge my tablet just fine and in two outlets. When I plug the phone into the computer it dings so the PC recognizes a device is being plugged in but it doesn't show up under the file browser. Am I hard bricked? Can I fix it? Should I try to get a new phone?
It's a T-Mobile Note 4 if that helps. I'm still making payments on it but I passed the year mark in February.

I looked up that error and there was multiple articles thatvsaid it could be a flash memory error of an EFS problem. Hopefully its something different, as both of those are tricky at best. Its a place to start though.
Install Kies and try the emergency firmware recovery.

[Bug] Phone crashes during loading

I do not even have my S4 mini for two weeks, and I've allready problems with bugs
The problem is that sometimes (tonight it happened the second time), when my phone charges overnight (~7-8 hrs.), at the morning the LED lights green, and the phone does not respond to anything. I've tried to press every button, the emergency power off combination, wait for 10 mins... but the LED is still green and nothing happens.
After taking out the battery it works again.
Only thing I did was taking out the Battery in order to be able to take out my SD-Card and copying some music to it.
Is anybody else facing this issue too?
PS: I haven't installed the latest firmware update, since I always wait 1-2 weeks before I install it
Lets check a few things first:
1. It's the S5 mini forum, so I assume you have one and not S4 mini;
2. Are the battery, charger and USB cable originals? If not, try different one, Samsung preferably;
3. Did you try removing the SD and/or SIMs for charging?
I would update the firmware as it may fix the bug that may cause the problem, if system related. To make sure it's not hardware, back up your days and do a factory reset, and if you are not on stock firmware then revert to stock first.

1. Yes, I do have a S5 mini now, my old S4 mini has died (hardware)
2. I mostly use the orginal charger or the one of my S4 mini. But yesterday, when it happened again, I'm 100% sure that I used the S5 mini charger
3. I will try this tonight
As I found out after my first post, this does not only happen during loading, but also when just having the screen off in your bag.
Upgraded Firmware yesterday, my brother plugged it in (I don't know which charger he used), and BOOM it happened AGAIN. Just like one day before I took out the battery, this time to copy maps to my extSDCard. And later, when sitting in the sun, it happened again, the battery was warm but not hot (I have an App that calles my at 41°C, but it seems like this has not been reached and the phone also didn't powered off when it had 44°C)
I will try to charce without SIM and SD-Card today, even if I don't think that it'll change anything.
PS: The emergency power off seems to work, I probably just waited not long enough

Note 4 from ebay: sometimes doesn't recognise charger/won't boot ; mmc_read failed

So i bought this note 4 off ebay. My other note 4 is busted (screen popping out, turns on and off) and i didn't want all the stuff i had for it to go to waste, i have a newer S8 too but i need a spare phone.
And off the box it would not turn on! This was fine you know because i was used to my old note 4 needing to be perpetually charging to stay on. That's just how it is i guess.
But to my surprise the real issue came up.... It wouldn't recognise charging! I put its battery on my old phone it had like 78% charge and was able to charge. I tried my old battery on it and it also wouldn't charge or turn on. So... i took the phone to a shop and was turned away cause they gave up and the other offered to replace the charging port for $150AUD then $120AUD (seemed like a an obvious scam).
They were able to boot the phone! Just from messing around with the battery more. And it seems if the phone is able to boot it can charge. I also did rigorous tests at a local food court like fingerprint, nfc tap and pay and flash photography is fine. However.... even though it was plugged into a power bank and was at 70% battery the phone died... And guess what it wouldn't boot and it wouldn't charge again.
I took it home.... My friend lent me his note 4 on the way with a newer battery. Over the night i got down a method of mitigating the issue... It seems the phone has an inability to initiate the battery to charge when it dies. By that i mean 100% of the time if i can replicate the issue by letting the battery die from there it won't charge the battery or boot. So the most reliable way to restart it is that you need another note to initiate the battery any note 4 even my busted Note 4 would do and you charge it for like 5 seconds then you plug that battery onto this note 4. I made an imgur post about it imgur.com/a/wxVj4AE
This makes sense of why the phone booted at the repair shops as i had initiated the phone on my old phone on the way back by chance. The weird screen also confuses me. Odin i recognise as custom rom thing perhaps it was previously rooted then improperly installed with stock samsung rom.
30% of the time there is this bootloader screen that comes up. "Could not do normal boot", "ddi: mmc_read failed", "Odin mode (high speed)", "system status: custom". The appearance of odin mode and system status = custom leads me to the idea that this once was rooted then rooted back to stock android. With further research i have also discovered that "ddi: mmc_read failed" is a system wide issue which i can maybe fix by 1) re-flashing with stock android and hope that fixes it 2) sending it to samsung to repair or replace for like $70 US 3) have some app to keep it awake almost all of the time in some form.
However i haven't seen this mmc issue be connected with ignoring chargers and not booting.
