Thanks for any help in advance.
My Nexus 5 device is unable to boot stock or recovery image. It's a locked bootloader, and stock ROM from my wireless carrier. I charged it with a 2 amp capable charger.
Symptoms: preceding the failure , there were strange slowdowns, apps crashing, and inability to charge the battery over the course of a day. When the battery finally died, that was the last I saw my Operating System. Now, when it's plugged in to power, it indicates full charge. If the power button is pressed it will show the Google logo, then cycle back to the battery charged icon. If the power button is held, the battery logo is skipped and Google logo displayed repeatedly. If the down volume button is pressed in addition to power, I get the screen where I can chose the recovery loader, but then the process of Google logo and reboots persist.
If nothing else, I'd like to grab built-in SD card memory contents and strip out a bitcoin key with about $40 on it that I didn't get to back up before it failed.
What have I tried so far: basically everything above to generate those symptoms. I also tried opening the back, and pulling one of the top cover and unplugging the battery entirely. No effect.
Cheers all. :good:
what happens when you connect it to your pc?
Possible power button issue? You could open the phone, remove the plastic power button from the phone housing, reconnect everything, and then try to boot the phone.
When I connect it to the PC, it goes through the same fully charged loop until I hit the power button for 2S, then it boots. If I hold power, it boot loops; if I leave it alone it fully charged loops (regardless of battery being attached or not). If I remove power button and depress it manually, I get the same loop.
This is a refurb from Google, about 8 months old.

So this is a weird problem I just started having today.
After putting my phone away during practice, I came back to find that it had only 1% battery.
It died en route to my room, and when I first plugged it in to my PC, it turned on and worked normally. After a while it turned off.
Now, when I try to turn it back on, the htc Raphael screen comes up, and it makes a short vibration, then goes to black for about 1 second, and then repeats. It has been doing this nonstop.
However, it only does so when it is plugged in to a power source. When it is not plugged in, it is completely unresponsive.
I have the elite RC2 ROM that I flashed back in November.
Any suggestions?
hard reset to start things off.
Hold down the volume down button, center button and then press the reset button with the stylus until you see a screen that says something like "this operation will delete all your personal data, and reset all settings to manufacturer default. Press VolUp to restore manufacturer default, or press other keys to cancel." then press volume up. Remember you will lose all data, phone numbers and anything else stored on the phone.
i know this problem
I have had several, i solve it taking press the power button long time during the boot.
Of course, the phone must be plugged in to a power source.
Problem solved.
I left it unplugged with the battery out overnight, and then plugged it in to charge, and it did not attempt to startup.
After letting it charge again it worked as normal.
I suppose the battery was so run down for some reason, that even plugged in, it did not get enough power to complete the boot.
It works now. About to flash Elite RC3 and a new radio.
Hello,
Hopefully I'm in the right place for posting something that seems to be this simple. The start of my problem is that the tablet will not stay off. When I try to shut it down, it shuts down normally, but then it starts to display the battery icons like it is plugged in and charging, but it is not connected to power. I can leave it in sleep mode and the charging thing will not happen, but turning it off displays the power charging screen and it further drains the battery. I figured something is screwy with the system so I would try to reset it to factory defaults. Now I have the other problem...
So I am trying to restore to factory defaults and I know to do this I have to start from off and hold down the up volume and the power button for a few seconds and as soon as the tablet starts to turn on release the power button but not the volume up button, and it should get me into the recovery/download screen. Unfortunately that is not working. I hold down the Volume up button and briefly hold the power button (3 or 4 sec or so) and I see the Samsung Galaxy Tab 2 7.0 startup screen and let go of the power button (still holding the Volume up button). Next I see the spinning blue circle around the Samsung logo and the tablet reboots. I can release the volume up button at any time after that and the results are the same, it just reboots. It's like it isn't seeing the volume button.
I have tried using the volume Down button instead of the volume up button but that too is just like I am not pushing any volume button at all. Once the tablet is on, the volume buttons function normally, so the switches are good.
Since I got this tablet used could someone have loaded something onto it preventing it from being rebooted into recovery/download mode? Maybe some custom firmware or something. I'm at a loss as to where to go next. Since I can't boot into recovery/download mode I can't get into Odin.
Any help is appreciated.

Hi. The tablet isn't rooted, is it? Can you try to boot it into download or recovery with the "quick boot" app from google play?
I don't think it is rooted, but I can't tell for sure since I can't connect to the Google play store. I tried downloading using the web browser, but my battery dies before if finished. I'll try swapping batteries and see what I can figure out. Thanks for the idea.
Rick
No, the device is not rooted. it also is not charging and I had a heck of a time getting it to connect to the play store. I think I need to try and reload the OS, but without being able to get into ODIN, or reboot into recovery, I'm not sure how to proceed. any suggestions?
When the battery thing appears do the power- volume up thing and hold it until the gtab logo appears.
I've tried that, and it just boots up as if I wasn't holding the volume button at all. Once the tab is booted, the volume buttons work as normal. I've even tried putting a different power/Volume/IR unit in (from a working tab with a broken screen) and that didn't make a difference.
I left the tablet all weekend and it just keeps showing that it is charging when not plugged in. By Monday the battery was 100% dead. It won't even charge. If I replace the battery with a battery from a working unit I'b back in the same place where I can't get it to boot to Recovery/download.
Hello,
I flashed the latest LRX22C image on my nexus 5 today.Had flashed it clean,wiping data,cache and system etc except the Internal Storage.Then I flashed the SUPERSU 2.37 ZIP .Everything was fine for about 4 hours.Then suddenly when I pressed the power button to turn the screen off,it was not turning off and the "Switch off" mode was popping up instead .Then, when I got a call,it switched off.The phone won't turn on again.It starts,the Google Boot Splash appears and the bootanimation starts for like 2 seconds and it switches off.Same thing for bootloader mode.
Please Help me!
EDIT: Now its turning on by itself and switches off in 2 seconds!
Sounds like a bad power switch to me, but of course that is just my opinion. :good:
sounds like a mech issue.
legit isue
I have the same problem on mine now... Basically my phone powered down around 45%. Battery. At the time i thought it was dead... But it wasnt. When i would plug into external power, either usb or through wireless charging it would power cycle continuously at the android splash screen.... (1 to 2 second intervals - even if i booted into fastboot) Interestingly it would never go to the battery charging mode. But automatically boot on charge... It did this for about 6 hours then i gave up and left it unplugged for a day. I plugged it back in and it started power cycling again, however this time on its third boot it came back to life . thats when i discovered i still had 40% battery... I dont know what exactly made it boot but it did. Oddly also on boot, it started optimising apps and finishing install again. I checked the md5 before I installed the update so no issue there. Since it powered up i have powered the phone off using the power button long push and let the phone power down. After doing this when i plug the phone in to usb charge it goes to the charge screen. No issue. That said, if i try to power up while tethered and charging it will not allow it. It just stays at the charge screen. As soon as i unplug the usb the power button allows the phone to power up and work... When booted up it charges as normal when plugged in. Im convinced there is an issue with the power management drivers or drivers for the button controls. My phone worked fine until the 5.0.1 update was installed. On my nexus 5. Anyone else or just us two? Ive had a hard time finding people posting on this issue.
Just some minutes ago my S7 froze because of Focus Gallery App. I don't exactly know what it did but the phone did not respond any more.
So pressing the power button did not bring back the phone either. After searching for a bit I found a way to simulate a bettery disconnect by pressing Volume Down + Power Button.
The Phone came back up and displayed the initial boot logo. Also the blue LED is on. But nothing happens from here on. I do not come to the "Samsung" boot animation and the phone simply
does nothing. Retriying Volume Down + Power Button doesn't seem to help too. I tryed all button combinations but nothing brings the phone back.
I also cannot enter the recovery menu. So no chance to reset to default settings.
I am running a stock Android on the phone. Nothing was done by me. No custom ROM, no root, just plain Samsung Android.
Is there sill something I can do?
Edit: I just got into whats seems to be ODIN Mode??? Can I do something from here?
Oddly this happened to me last night although I may have inadvertently done it. But the only way I was able to get my phone functioning again was reflashing the OS to the phone.
How did you manage to get the phone into Odin mode? I'm having the same issue with the phone being totally unresponsive but the blue LED on.
if you can reboot your phone with the VOL Down/Power, when the screen goes black, quickly press and hold VOL Up, Home and Power. it should enter recovery. or hold Vol down, Home and Power to enter the download screen.
I have the S7 Edge (rooted, custom ROM) and it's running fine. My girlfriend's regular S7 is having the same issue though.
When she plugged it in to charge last night, she checked it a few minutes later at which point the phone had (started to) reboot. The blue notification LED was on and the screen had frozen at the 'SA' from the 'SAMSUNG' startup logo. Forced a reboot with down+power, resulting in just the blue LED (no logo this time). Phone was unresponsive (couldn't force a reboot again) so left the battery to drain overnight. The phone is completely dead today even after charging - no LED, no boot, no anything.
I'm not sure if she had the phone scheduled to perform an update overnight and it froze halfway through, but that would be my first guess. So far, no fix.
I have a 2nd Gen Moto G that was pretty much in mint condition & prior to yesterday it showed no signs of any potential problems. Then last night the screen completely froze & wouldn't allow any input. The phone then shut itself off & I figured it would just restart & be fine. Instead it went into a constant boot loop where it reaches the white "M" animation screen then shuts right back down. I played around with it for a few hours today & did a ton of searching on the internet with no results.
I also should state that the battery did not die when this happened. I mention that because there were some posts where people let their battery go completely dead then they couldn't get their Moto G to power back on, however that was not case for me as the battery had well over 50% charge when this happened.
Things I have tried in order to fix this:
Using a different charger (both wall and USB to the computer).
-Holding down the power button for 7-10 seconds while plugged in.
-Holding down the power button for 7-10 seconds while not plugged in.
-Holding down the power button for 2 minutes or more (while plugged in and while not plugged in).
-Holding down the power button and volume up buttons until the phone starts (while plugged in and while not plugged in).
-Holding down the power and volume down buttons for 2 minutes or more (while plugged in and while not plugged in).
Now this step does bring up the fastboot menu however selecting any option in this menu just causes the phone to back into the boot loop. And yes I know how to access options in this menu (down volume to scroll & up volume or power button to select).
So basically everything just sends the phone into boot loop. Is the phone toast? Also I should mention that all day today it would randomly try to start itself & get to the Moto animation screen & then shut down & that was while it was sitting on the desk & I hadn't even touched it.
If the phone is toast is there any way I can access files like pictures by plugging the phone into my computer while the fastboot screen is up?
Alright so seeing as no one has any suggestions (understandably) & based on the searching I've done I'm assuming that the phone is just DOA. However does anyone know a possible answer to my second question which is, if the phone is un-savable is there still any way I can access files like pictures by plugging the phone into my computer while the fastboot screen is up?
