By the coincidence, is your batt serial no beginning with BD? If so, look on the battery. Is it swollen a bit? If so - call samsung, they will replace battery free of charge.
If not, try to connect phone to charger, insert battery, go to recovery and make full wipe.

it might be a power button issue

ok, this may be tricky.
while keeping volume down and home - slice battery in. If phone would boot in download mode (even just for a while) - then it will be power button issue.

it boots up on download mode for seconds and then powered off again....

Im digging up this post because this is the same problem i had.
I ended up removing the power button all together, carefully popped it off the motherboard. The phone no longer boots for a couple secs and powers off again so i think the power button was the issue. Now i have the problem of powering on the phone. I tried booting into download mode (to have the reboot option) by holding volume down+home while plugging it in but nothing happens, all i get is the battery charging icon. Ive been into download mode before i removed the button, but like the OP, it would only be a second or 2 before rebooting. Am i doing the correct procedure for download mode? Perhaps my timing is off? Any suggestions?
At least i do get the battery charge and it stays until i unplug the phone, no more boot loop!

Ok so i managed to get the phone to power up without going into download mode using this method i found on youtube. No boot loop and fully powered up now, the only thing is that im stuck on the lock screen. My friend cant remember his pin so i cant get in, the only option left now is to boot into recovery and do a factory reset yes? Well, how can i do that without a power button? Any suggestions?

Major issue with my N7

Ok everyone I am having a major problem with my N7. This morning I noticed it was out of power so plugged i tin like normal, then I went to turn it on got the Google logo then it went to the Nexus logo. And it kept cycling through the nexus logo for hours and will not turn off. Whenever I try to turn it off it just restarts from the beginning. Now I didn't buy my tablet from the play store so I would have to go through Asus for a warranty replacement. Has this happened to anyone else in the past?
Some info. Stock, unrooted, locked bootloader, stock 4.2
Well this never happened to me before. Did you try removing the battery?
Well, to start, unplug your N7 from the power source and hold the power button down for about 15 seconds, this should force it off. From there, turn it back on and let us know what happens.

I don't see that you have tried holding down the power and the volume down. This should get you a hard reset.
Here is a short topic where a power and vol down worked for someone where a straight power down did not:
http://rootzwiki.com/topic/30101-reboot-tip/
it's the last post (#6)
Rather than trying to run the battery down, which is not all the way down when it shuts off and would take a long time to discharge just sitting there, you could pull the battery if you feel comfortable opening the case. It's not glued or anything and the battery has a ribbon connector.
So its in a boot loop? Reflash the image with Mskips toolkit option 9 after booting into fast boot mode. If that isn't the problem then do a warranty return. Not sure why you're stuck in a loop.

Stuck on "Erasing..." after factory reset attempt

Hi, my parents N7 wasn't used for a long time and it was completely dead. It couldn't even stay on when plugged in.
I went into the shutdown mode to charge it for an hour or so and managed to get it on.
The battery was at 2%. I decided to do a factory reset while the device was plugged in but now it's become stuck on the Erasing screen. Its been there for a few hours now. I've tried restarting but it just goes back to the Erasing screen. I've also tried booting into recovery but it just goes straight to the "Erasing..." screen again.
When I press power and vol up on the Erasing screen it tells me "Formatting /data...." in small yellow writing but like I say its been like it for hours.
Any advice? device is completely stock, not rooted or anything.
Thanks
Make sure you are using the OEM 2.0A charger from Asus and leave it connected to charge overnight for at least 8 to 12 hours. Unplug it and wait a few minutes before attempting to get into Recovery Mode or Bootloader (hold Volume Down & Power to restart) - if that work, reconnect the power supply as you want it to get power while cycling.
Keep a close watch on any error or messages popping up on the screen as you do this - post them here.
What is your goal in doing a Factory Reset ?
If the battery is completely dead & remained in that state for a long time, it might not come back to life & a replacement battery is probably the answer for the long run - is it out of warranty ?

Hi the correct has been used. I left it charging over night and is now at 100%. I can tell this from the battery indicator in the middle of the screen when I power off.
When I try and boot into recovery (vol - & power) the device just goes back to the "Erasing..." screen where it stays indefinitely (to my knowledge). The screen is still animated (the robot with the blue rotating graphic inside him).
If the warranty is 1 year then I believe it has expired.
Thanks

Is there any way to clear the pending factory reset request? I can't believe an untouched, un rooted device has just bricked like this
I am putting a $20 reward via paypal for anyone who can supply the solution to this as a thank you for the time they put into it. Thanks.

It's strange indeed. Make sure you keep holding volume down until you (in theory should) get to the bootloader menu.
I have the same problem. Whenever I turn the device on, it goes straight to Erasing... screen, no way out. If I try to do Power+Volume Down thing, it turns off the device, then it'll start again and back to Erasing... screen. Help! :crying:

VZW Note 3 Plug in power issue

Hello,
First I've looked everywhere for the last three days on something about this and I can find nothing so I come to you in a new thread for help.
I have a Verizon Note 3
SM-N900VZKEVZW
I'm having an issue where if I take the battery out and put a new one in I need to plug the phone in before I can power it on. I was running Hyperdrive but I reverted back to stock.
Here is an example of the issue.
If I shut down the phone and don't remove the battery I can press the power button and it will power on just fine; however, if I shut down the phone to put in my second battery that is fully charged or just take out the original battery and put it back in the power button does nothing until the phone is plugged in. When I plug the phone it the battery icon will come on.... the screen will freeze with a snow screen and then go to the stock battery changing screen at which point I can use the power button to power on the phone.
Another weird thing is I cannot boot in to recovery with by holding the power button and down on the volume button if I do this the phone will just keep looping at the Samsung screen with a lock on it; however if I boot in to recovery through safe strap I can get there.
I've done a factory reset and reinstalled the rom and recovery and I still have this issue.
Attached Images are the snowy screen and the screen that will keep rebooting if I try to get to recovery with power and volume down. (now the snowy screen has changed to a battery screen superimposed with the safe strap screen it only shows up for a second before going to the battery charging screen)
Please someone help!
Second question what should I do if I need to send the phone back to samsung? Or should I just deal with the battery thing? Other than that the phone works fine.
Thank you.

[Q] S4 in Bootloop after Lollipop Update

Dont know if any one is facing the same problem.
Installed Lollipop in my S4 over the air, 2 weeks ago.
A week back, my phone entered into BootLoop mode. Phone gets re-started. I can see Samsung logo and it gets restarted again. I tried removing the battery and kept it back. Started working fine then.
Since today after noon, my S4 is in complete boot loop. Tried removing the battery and kept it back. Yet it is in bootloop.
Unable to enter into Developer options also. Please help
I hit the Power Button against a Flat Surface. It Vibrates and shows the Samsung Logo. But then it turns off.
Is the battery empty maybe?
My guess is that your power button is faulty. Either try to wiggle it lose or replace it. It's really cheap
If it reboots in download mode and/or your recovery then it's your power button.

phone won't boot/start up

I have a at&t S4 that all of a sudden today stopped working. When I restart the phone by taking the battery out and putting back in, it gets stuck on the Samsung Galaxy S4 logo and then a black screen. I tried going to recovery mode(volume up + home + power button), and it shows recovery booting in blue for a sec then goes black. I tried for download mode the warning comes up but after pressing volume up it goes black. I really don't know what to do at this point.
Tried using kies or smart switch to perform a firmware recovery?
Yes, the computer doesn't recognize that the phone is connected. It's as if when the phone goes to the black screen its actually powered off. The only time I get anything from the phone is when I pull the battery and reinsert it.

When the phone battery are too low, the phone could behave like that too.
Do you know that battery is fully charged or has more than 60%?
If not charge the phone first.
Plug the charger. If you did not see any sign showing that you phone is charging, press and hold the power button for 10 sec and release it. You should see the phone charging image.
Let me know whether your phone has enough battery power left but showing the above mentioned problems.

Yes, the battery is fully charged. I have another S4 Active that I've swapped the batteries with, along with a spare official Samsung battery and charger. It doesn't matter which battery I use, the phone acts the same with any of the 3.

If you have enough battery power left but the phone was behaved like that, you might need to flash the firmware.
Are you in lollipop or kitkat? For the time being, the only firmware available for kit-kat and lollipop is NB1 firmware cooked by muniz_ri . You can get it from here.
You mentioned that you can go to download mode but the phone shut off when you press volume up to go to the download mode after the warning.
Try the 10 sec method. Go to the download mode (power+home+volume-down) but keep holding the power button for 10 sec even though you see the warning message appear. Then you press volume up to go the download mode. Try this way and let me know.

It was on Kitkat. I can press the volume up and get it to show the download android screen but it immediately shuts off. Holding the power button for 10 secs. and then the volume up didn't do anything. The phone shuts off after 1-2 secs. of doing anything.

That is strange. The same thing happened to me. But I avoided the phone shut down by 10 sec methods.
Just hold the power+home+volume down for 10 sec, even though the warning sign show up, and then let it go all of them. Plug the phone to the computer and then press the volume-down to go into download mode. It works for me. Not on the first try though.
Try doing that with batter charger plug in too.

Thanks for your help. I figured out whats wrong, its got a faulty power button. I took the phone apart, put it back together, and was able to get it to boot completely. The slightest touch of the power button causes it to reboot though, so I'm going to need to replace it.

Glad you found the problem. I was trouble shooting for the software error.
Yes, power bottom could give you a problem too. I use screen off app so I do not have to use power button to turn off the screen.
