So I installed Greenify last night, I have no idea if it has caused this but it was the last thing I did before my phone went kaput so I am working on that theory now. Last thing my phone did was have the bar "Greenify has been granted SuperUser" or words to that effect and then hung. I tried a reboot at this point by holding down the power button for 10 seconds, screen turned off but phone did not reboot. From that point my phone has been completely unresponsive.
The phone registers as there when plugged into my PC, but doesn't show up to move files to/from. Also when plugging in a UTG cable the phone powers external devices. I am thinking at this point of running the battery down till the phone HAS to switch off and then plugging it in and seeing if anything different happens. Any other advice would be appreciated.
I have encountered this when I tried ART instead of Dalvik. if you use ART, I would suggest you try Dalvik.

My phone did the same after installing the Root companion for GSAM battery monitor. Like you said it at least responded when the usb cable was plugged in. So it was fortunate enough that I could just open the command prompt and reboot the device with adb commands.
adb reboot
You can restart your phone manually. Press the vol up and power button together and hold until the phone reboots. It will take a while so just wait.

I have been running ACS 1.2 for quiet a while now with no problems, Journaling on. Tonight I started experiencing force closes along with on my physical keyboard letter R,F, and C not working at all. So I decided to odin back to stock and start fresh. I have done this multiple times with not a hitch. Anyways my problem is I can not get into download mode no matter how many times I try, it just boots into the ROM. Also, has anyone else experienced their RFC keys just stop working?
Thanks.
Have you tried booting into download mode with your device battery removed and connected to your computer via USB?
Yes, it just shows the battery charing screen and flashes on and off.
Your suppose to KEEP battery OUT completely. plug in phone to usb via Computer. Then Hold the "1" and Power Button.
all this WITHOUT a battery. Once its in download mode. u can put bak battery
Make sure you press and hold the "1" key first then add the power button. If you booted into the ROM then you pressed the power key first.
I'm 100% sure I hit the "1" first then the power button. Not sure what the heck is going on. Tried with battery out and usb plugged in, tried with battery and usb unplugged and holding buttons, while putting the battery back in...nothing. I have done this many times before and never had this problem. =\

Damn...I have seen other users report similiar issues. Try keeping the battery out. Hold the power button for 30 seconds to discharge the circuit, then try plugging in to computer and get into download mode with the battery out. Try other USB ports and even another computer to verify it don't work. You said you had a good cable right?
you had usb plugged in, wheres the part where its plugged to a computer via usb?

I saw you said that you "hit" the 1 button. I assume you meant that you are holding it.
But what I really wanted to ask was- are you sure that your 1 button isn't broke as well?

So the other day I let my n7 die completely, which has happened in the past. Today I went to charge it with my computer and turn it on, so I plugged it into my laptop's USB port. For reference, I just installed Windows 8 and there are no android drivers on my laptop. Anyway, I plug it in and hold the power button and it shows me the google screen, then it goes to a black screen annnndddddddd.... Nothing. It stayed there until I did a hard kill. I can get to the bootloader as well as TWRP. Within TWRP I cleared the caches, and ran a fix permissions. Nothing. I've backed up in TWRP and have yet to wipe my data because that's a last resort for me at this point. Right now its sitting on the charger. When I plug it in I get the battery thing as well as the battery charging thing, however after the battery charging thing goes away I can't call it back up. (usually it'll go away but you can hit the power button and it will come back).
This appears to be a hard brick but I'm not sure. I was running 4.4.2 stock, rooted, bootloader unlocked, with Gravity Box, but that's it. Otherwise I've been running normal user stuff and it has been (up until now) just fine, normal battery life and everything.

I fixed it. Something happened between the battery draining completely and me trying to turn it on that was causing a /system mount failure, thus the black screen after the bootloader. Here's how I fixed it:
I downloaded the full restore zip from Google (Mine was KOT49H at the time of posting this).
Then I opened the package, and the second package within the first one. I extraced the system.img file to my desktop.
After extracting the system.img file, I used fastboot on my computer to flash the system in my bootloader, and now its back to normal. No data was lost, nothing broken. I re rooted and everything seems to be in working order.
Good job! I know none of my 1st gen N7's liked to be drained completely so I make a big effort not to. Phones don't seem to have issues like these tablets sometimes do.

Hey guys,
Appreciate it if you could spare me some advice on how to proceed.
So I was watching a twitch stream and all of the sudden tablet froze, and the audio froze as well causing a large super high pitch noise, I hard-reset the tablet but instead of resetting it just turned off, I started to browse the forums and found that a combination of (POWER + VOL UP & DOWN + HOME) would reset the tablet,now what this did for me is turn the tablet on but it was stuck in SD CARD Mode, back again to the forums, read that letting it discharge fully and then it will be able to be charged and turned on, that worked tablet was back doing some various tasks no video again and then boom freezes again same symptoms except this time I couldn't get it to go to SD CARD Mode its very finicky after trying at various times in the day I finally got it to work, same process except this time as soon as it turned on I went into recovery factory reset it to stock, worked a bit longer this time only installed chrome, and it froze again (don't think it was chrome) , rinse repeat and I flashed the latest firmware with ODIN worked fine, I've gotten to the home screen ran through the "factory new" set up and it turned off of me again.
I plugged it in let it charge, came up with battery icon 5% 10% ect, then I left it for a while, I came back and I cant even get it to show the battery percentage(tap power) let alone turn on.
I'm fairly sure that eventually I can get it turn back on but from there I don't know what to do.
TL;DR - Tablet Froze, Hard Reset, Froze again - Rinse Repeat, ODIN to latest STOCK firmware, tablet worked for 5 min before turning off again (plugged in), present situation
Any ideas as what to be causing the freezing and how I could remedy it?
Also sometimes when it froze it turned itself off without me hard resetting it.
Thanks its been driving me insane,
Please do not hesitate to ask me to clarify or provide more information so I can help you help me.
Maybe youve got the loose battery connector problem?

What would you suggest I do, submit it to warranty ? Will they disregard the fact that knox has been tripped if its a hardware issue ?

I had the loose battery connector problem, but the symptoms do not sound the same as mine. I could get mine to boot up, but the screen would flicker and a few white lines would appear before it would reboot itself. I actually started a ticket with Samsung and got the packaging label but, upon further reading, realized that I was pretty much SOL after tripping knox, and didn't want to risk the chance of getting charged for just sending it in. If it is indeed the loose battery connector, you should be able to remove the back cover yourself and fiddle with it. Ultimately, mine needed re-soldering, and I was able to find a local electronic repair shop to do it for me for cheap.
Good luck!
UPDATE: I've managed to get into SDCARD MODE yet again, except discharging seems to get out of it, but once I plug it back in it doesn't come up charging it just black screen, until I hold some buttons and arrive back at sdcard mode. Good times.
Trying various things to get it to boot..
EDIT: Appreciate the insight Squez, I want to exhaust all the other options before opening it myself, if Knox didn't void the warranty to some degree, opening it up should put the final nail in the coffin.
EDIT2: Good news, sort of, tablet isn't dead! after numerous attempts with charge SDCARD mode, discharge, It finally start to charge properly and I managed to get it to boot, worked for a few hours then I left it to charge, and went to sleep, woke up and wont turn on again, but I am in SDCARD Mode again but need wait for it to discharge from presumably 100% ....
[What do you mean Sd card mode? DOWNLOAD mode?
Also no need to let the battery drain.
Just press VOLUME DOWN(not volume up) and POWER together then hold until it restarts.
This is a hard reset and will ALWAYS work unless the device is hard bricked. It is the equivalent of a battery pull.
I continually see here and there incorrect information regarding key combinations, even in so called guides, this forum is even guilty!
Here is what works on the 10.5lte, as far as I'm aware its the same for all versions, indeed pretty much any Samsung device.
HARD RESET:
VOLUME DOWN - POWER.
Hold until the device restarts.
DOWNLOAD MODE:
HOME - VOLUME DOWN - POWER.
Hold until the device boots.
RECOVERY MODE:
HOME - VOLUME UP - POWER.
Hold until the device boots.

I should of posted a photo earlier but here is one I found on google of same screen: (check attachments)
Except UP KEY and DOWN KEY don't do anything, its just this screen, if you attempt to hard reset ect, it will just reload this screen, hence the discharge, then plug it back in and hope it begins to charge "battery icon appears". I have gotten it to boot like this a few times.

How did you get to that mode? Looks like its trying to flash from the sd card. Ive seen safe mode but not that.

Yeah its strange as.
I'll have a look at that, thanks.
EDIT: It just finished discharging and now I am on the battery screen.. Usually once it charges here I can get it to boot, what I'm curious is what on earth keeps causing it to freeze up, because in download mode and twrp (gone since i flashed stock via odin) it wouldn't freeze at all, only have issues with it once its booted or charging. I installed a logcat earlier hopefully that should shed some light on the situation,
EDIT2: Well another very interesting thing, the official Samsung charger wont charge it, only works if I plug it into pc or use a non-official charger, strange thing is nothing is wrong with the samsung charger or cable since I can charge my phone fully from it. These have to be some of the strangest symptoms.
EDIT3: Only works through USB port on PC for now, non official charger comes with red X on battery once booted. I assume you can work around this once rooted but that's for another time..
EDIT4: Charge through pc to around 2-3%, boot device, plug into official samsung wall charger and it begins to charge properly.
EDIT5: Hooray back to step one, trying get into SDCARD Mode, same thing happened left it overnight and it wont turn on or charge anymore.

i am pretty sure the HOME - VOLUME DOWN - POWER. puts the 10.5 into the sdcard mode.
my tablet is doing very similar to sunb3ar findings.
have had it come back to me once from sdcardmode.. (let if go flat and starting charging then it would start via normal buttons)
it crashed not long after that. it got stuck in sdcard mode again, but this time none of the drain flat, put on charge has worked.. just blank..
fyi- we try to put it in RECOVERY MODE, but it does not work when in this crashed / sdcard mode state
i even disconnected the battery and then plugged back on charge.. nothing..
today i tested the battery volts, 2.8v , for a 3.8v i thought that was ok. i attached my RC lipo multi charger set to 1amp 3.7volt charge, direct to the - + on the battery- got it up to 3.5v, plugged back in, put the charger on- the sdcard mode (most life it has shown in a week).
still not coming up with 'battery' display to say its 'turn-off and being charged'. just the sdcardmode might disappear and return..
i am currently adding mode charge to battery... will try to HARD RESET next.. since i have not tried that combo yet..
HARD RESET:
VOLUME DOWN - POWER.
Hold until the device restarts.
edit: i took it off 'direct' charge, battery at 3.7volts.. then plugged in normal charger, i got a 'battery symbol' but it had the lightening bolt, not a %.. so i unplugged and reconnected to my direct charge to give the battery more volts. i am surprised that the unit seems to think a battery with 3.8volt as it specs seems to not be like with volts not much lower than 3.8.. could be time for a new battery if we can get this thing to restart
Months ago I rooted and flashed a lollipop stock ROM. It's worked flawlessly ever since, so I doubt it's the cause of this problem.
Suddenly my (international) G3 has started doing a cycle of freezing, rebooting, staying awake for a few seconds and then freezing and rebooting again. This started happening this morning, while using the "reddit news" app. I don't think it's related to the issue. Now, after a few hours, it's stopping the boot cycle at the LG logo, and it doesn't seem to go anywhere from there.
Previously, when it did boot and stayed awake for like 10 seconds, it showed some strange behaviour. Wifi didn't turn on, the phone got pretty warm, and whatever mode of USB connection I chose, USB debugging never turned on despite being enabled in the developer options.
"adb devices" in windows cmd doesn't show anything in any part of the cycle, so I can't take a logcat. The phone isn't awake for long enough to do it on the phone either. How can I find out what's suddenly causing this? Has anyone else experienced it? Trying a hard reset via pwr + vol down just shows me the LG logo again.
Does it still go into download mode when you press volume up and plug in usb cable?

I assume so. I've never used it before so I'm not sure what it looks like - but I do see a little box in the middle of the screen saying "Download Mode", with a little graphic underneath.
Cross-posting this from r/NextbitRobin
So Tuesday night before bed I went to check my phone (which had been on the charger for the last couple hours and so was at >95%) and noticed the volume button was not responding. I figured something buggy was going on, sometimes I need to reboot my phone every couple of days to get it to work properly (especially if it had run down into low power mode before recharging), so after unplugging it from the charger, I held down the power button, selected reboot, and clicked okay. The phone then proceeded to shut down, but not start back up.
When I tried to start it up again by holding the power button, I got no response initially. Then I was able to get it to buzz/vibrate, but the screen never came on.
I tried holding down the Vol- button and the power button together for 20 seconds to force a reset, and it vibrates a couple of times, but nothing happens.
If I plug it into a charger, I don't see any LEDs illuminate, and it just vibrates approximately every 3 seconds (not continuously, it seems to have some semi-random pattern). If I unplug it, the vibrating stops, but I still can't get it to turn on. It does not seem to make a difference if I am using a wall charger or trying to charge it off my laptop.
I have not rooted the phone or installed any custom ROMS, and have had it since I bought it on Amazon in June of 2017.
Any ideas what might be the issue? Any tips for reviving my phone?
This doesn't seem to match anything I have been able to find with some basic google searching.
Edited to add that I also tried removing the sim card and starting it up without one, but that did not appear to make a difference.
Update: I left it plugged into a wall charger for about 18 hrs and when I came back there was no change in behavior.
This many sound repetitive but lets first get the obvious out of the way so that we are sure you tried the most basic things for sure.
Is there an issue with the cable not able to charge the device? Can you try changing the cable?
Power + volume down for 30 secs / 1 minute / few minutes. This usually helps, sometimes more than 30 seconds for some reason. Try doing it while plugged in.
When you connect to the laptop what happens? Does it power on for a minute or vibrate?
Do you have adb installed on your computer? does you device get detected on your laptop?

Tried charging it with both the OEM cable as well as an amazon basics USB-c cable (both of which had been used to charge the phone successfully in the 24 hrs before it went wonky), no noticeable difference in behavior.
Held the power + volume down buttons for 180 seconds, did not boot. Repeated this with it plugged in (wall charger) and it still did not boot.
When I connect it to my laptop, I get the same behavior of vibrating as when plugged into a wall charger, but it does not boot or power on, nor does the laptop detect the phone in any fashion. I do not have adb installed on my laptop.
Anything else I can try, or is the phone a write-off at this point?
First step to solving any device issue is to somehow boot it and get in any mode possible. Since you can't do that I can't think of any other way to get it working.
I'm having the same issue, phone is not giving me any signs of life...frustrated at the moment
It's a total long shot, but try carefully cleaning out your charge port with a needle or a small pin and a little bit of alcohol. I pulled quite a bit of pocket lint out of mine and it works fine now. It didn't look like it was that dirty, but I pulled out a large ball bearing sized amount.
Other than that the only other thing I can think of is that your battery might be shot. It might have been taking enough of a charge to try and turn on, but not enough to do so.
