[Q] Nexus won't turn on.

I have just received my new phone from the insurance company as my last one got stolen. At first it seemed fine, I put it on charge, reset the phone and logged into Google. After a few minutes I went to check on it and I cant get it to turn on (or maybe its turned on but the screen isn't).
What should I do? Is this a common thing? Thanks.

Did you pull the battery, reinsert it and hold the power button down for a few seconds?
Also, when you were charging with the phone off did you get the charging graphic on the screen?

Thanks for the reply, i think i have fixed it now.
A better explanation of the problem I was having:
After a small amount of time the phone would freeze and very slowly the screen would fade to black, like the power to the screen had been taken away.
Even after pulling the battery, it wouldn't turn back on unless I waited without-battery for a while.
How i think i fixed it:
Waited a while with the battery out and turned back on, when i managed to turn it back on it had a half downloaded 4.0.4 update (could this have caused it?)
I kept trying to make it last long enough to download the whole update file, luckily it resumed from where it was last.
After installing the update it's been fine.

Sounds like a case of 4.0.2-itis.
4.0.4 is the wonder cure for all phone problems!

[Q] ATT LG3 Won't Turn On Completely Unresponsive

I have an ATT LG G3 yesterday it the phone suddenly won't turn on. It was on with mostly full battery and now won't turn on and is competley unresponsive. When I plug it in, no charging light comes on. Additionally I tried the hard reset by holding down power and down volume key; this gave me nothing.
Thinking that it might be a battery problem, I left it plugged in all night. But still nothing.
Any ideas?

Had the same problem

I had the same problem and pulling the battery wasn't cutting it. This worked for me:
1. Take out the battery
2. WITH THE BATTERY OUT OF THE PHONE AND NOT PLUGGED IN, press and hold the power button for about 15 seconds.
What this does is it drains all the power stored in the phone and takes the power source away so the phone can fully reboot and refresh the power cycle.
3. Replace he battery and plug in the phone to the OEM LG Charger that came with the phone.
4. Let the phone charge for about 15 minutes then try to turn it on.
This worked for me but some phones are DOA being the phones are still in early production. It takes a few months before they work out all the Kinks.

I figured I'd add my two cents. I had the same issue with my D851 (T-Mobile) version. I was copying a file over my from computer and halfway through the phone shut off. I thought the screen timed out, but it wouldn't turn back on. I pulled the battery, tried holding the power button without the battery for 60 seconds, putting the battery back in, charging without the battery... nothing. The LED would never light, and the phone would never turn on. I contacted LG and it's currently on its way back to them for replacement.

I work for a wireless service provider and not only sell this phone but own one. I also had the problem and unfortunately the battery out power combo did not work for me either and swapping the battery was to no avail. I have seen one other DOA as well. I have noticed the new LG models have had some significant flaws and lemons when they've first come out but I feel the specs and price you get are worth the risk so if this does happen to you I wouldn't throw in the towel on LG quite yet. However the way LG reacts to this will speak volumes to the company's overall success in the industry.

what would happen if I tried returning my phone with root and another rom on it and it won't turn on?
I tried manually going to twrp but went to recovery instead, restarted phone and now it won't turn on. I've tried the suggestions in this thread to no avail.

Won't turn on
My LG G3 D855 first had this problem of restarting on its own when I play with its camera and while restarting, the phone is getting warmer. And now, it wont turn on. I press the power button while it is off, it tried to turn on until the LG logo screen and then it shuts down on its own and restarting non-stop until that LG logo screen and turning off again. When I plugged in a charger, it manages to turn on but only to the pass code part and then it turns off again and the battery charging screen when phone is turn off, is displayed. The battery showed was higher than the battery showed when during the pass code stage. Is it the battery problem? I haven't send the phone to be check yet, I hope its the battery..

Clearing phone
My won't turn on either. I filed an insurance claim and am getting a new one. But I have to send my old phone in. I was wondering how I can get all my info off of the old phone before I turn it in. I don't want some one to get my info that is on that phone. How do I clear it all with it not turning on. Is there a hard drive from the phone I can remove?

yes for i have solution if u want to turn on your phone ...
First put phone on charging and then turn it on after 10sec (dont remove from chargning ) when its completelty on ... then remove from charger ...

The plan: Put the phone into recovery and then push " power on".
The method: To get into recovery, push power and volume down together until you see "system recovery" ( it will take a while- maybe more than a minute) and touch "continue power up" by depressing the power key.

h! i have rooted my G3 and insatll TWRP it works .. but when i press volume down+power button it wont boot to recovery. ? i can easilt boot to recovery using ADB .. but how can i boot to recvery using power and voulme keys ..

http://lgg3root.com/lg-g3-root-tutorials/how-to-manually-boot-into-cwmtwrp-recovery-on-lg-g3/ Said better than I can. Be sure that you are firmly pressing both on the power and volume down keys, at the same time, don't give up- To be sure I have constant pressure, I take off the case. I do this each time I restart the phone.

Oh awesome. I was browsing the web having the same problem and this totally fixed it for me. Cheers!

Stuck in downloadmode, Screen off, tablet won't respond, explanation inside

So, after flashing the latest firmware from sammobile for the Galaxy Tab S 10.5 with Odin, I am now the not-so-proud owner of a what seems to be unresponsive - working - device.
Let me explain:
I just downloaded the latest firmware from sammobile.
I followed the instructions from sammobile, which basically says normal flash with Odin.
Plugged it in, started Odin, put the file in the right place and started the flash.
Odin does its thing, everything goes well, device is showing me a nice blue dotted bar which is filling up slowly, good.
And then suddenly Odin reports "FAILED" after is was done with /system.
Device has stopped working, blue bar not filling anymore.
I reset Odin with hope to restart the flash, with no result.
The device is not being recognized anymore by USB, and it's now stuck in the "odin mode" screen.
After seeking some advice on IRC I found that the only way to get the power off is to unplug the battery, which is harder that it sounds.
So after a good 30 minutes of carefully prying and making my way around the tablet I managed to get the cover of.
As I'm looking at the naked device and wondering "how the hell do i get this battery out". This is not like a normal phone or laptop or any kind.
I found a couple of little screws, 4 of them, around the battery so I unscrewed these and the battery came 'loose' but was held in place by 2 flat cables which I couldn't remove.
Put them back in, and all of a sudden my tablet's sceen was 'off', but I'm not sure it's really powered off because the powerbutton has no response.
I'm stuck and it the thought of just binning the tablet is frustrating me.
Anybody got any ideas of what this might be and how to fix it?
[edit]
I found out it wasn't powered off, it was just the screen. I could feel the CPU was still emitting heat.
So I unplugged the battery, let it cool down for a couple of minutes, plugged it back in, and now there is nothing.
No screen, no usb recognition, no power.
Any suggestions are appreciated.

You didnt need to take out the battery. Your should have exit download mode by doing power, home, vol down buttons for 30 seconds and it should reboot and you could of tryed again. If that didnt work you could have let it drain. Im not sure about helping with the battery part as i never opened it.

easy fix - check http://forum.xda-developers.com/showpost.php?p=50412284&postcount=8
no need for draining the battery. tested and it works. happens once to me, use above method and problem solved.
can use my modded version attached, but, please be aware, it's ONLY FOR RESETTING THE STUCK DOWNLOAD MODE !

I tried that, but didn't work. The tablet was/is unresponsive. Draining wasn't an option, battery was just fully charged.

Thanks for this! Am going to try this once my screen works again.
At this point it goes 'on' but the screen doesn't, and there is still no USB recognition so I guess I got a nice expensive paperweight

[Q] HOX wont start up after new battery replacement.

Hi.
I had a HOX which I wanted my daughter to use, which was running android Revolution custom ROM, but the battery was on the way out. So I purchased a new battery, dismantled the phone with no issues, changed out the battery and put it back together. I then gave it a full charge, till the charge light was green. But now the phone will not switch on at all. I have tried the usual button tricks, power + Vol Up & Down, Power + Vol Down to try and reset the battery status or boot it into recovery, but nothing works. I just get a Green double flashing light after about ten seconds, and this only goes on while you hold the power button down. The phone is recognised when you plug it onto the PC. I tried updating the drivers in the PC to see if this woudl help, as I read this as a suggestion as well, but nothing seems to be able to get it to start up again.
Took it apart again today, put the old battery back in, checked no cables had come out. All well but it still will not power up.
I am at a loss as to why this is the case. Spent the last week on and off online looking for a solution, but have found nothing that works.
I can't find anything about a double flashing green light when you try to power up the phone.
If anyone has any idea how to get it at least booting back into recovery that would be great!
TIA.

[Q] SM-T700 Froze, Powered off - Soft bricked?

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
