[Q] device won't turn on - Nexus 7 Q&A, Help & Troubleshooting

Hi all,
My Nexus 7 has had slight issues with the power button since day one in August but now I can't turn it on. Hard reset doesn't work and when I plug it in to charge it will show the battery charging icon but screen will go black if I hold the power button in attempt to turn it on. While plugging it in to my computer I get horizontal lines.. I have not dropped or hit my device in any way to damage it. I'm also rooted / unlocked but was done back in September so I'm not stuck in a boot loop. Please let me know if you guys have any advice. Thanks

[Q] Bricked or jusr dead?

Hi all,
I got a Samsung Galaxy S (i9000) from a friend who wanted to toss it away since he says it is broken.
I want to see if it is or not.
When I try to turn it on, complely nothing happens. When I put the charger in (or the USB cable fot that matter) a battery sign appears with 5 dots under it which move from left to right. When I try to switch the phone on nothing happens
When I wait a while, the screen goes black. When I try to switch on, nothing happens.
When I push the home button, the green charging battery appears again and the back an menu button light up.
A factory reset is not working at all. Can it be that the power button is broken??
Any help would be greatly appreciated!
Regards,
Vincent
Fixed it!
Hi,
I was able to fix it.
Thanks to this sticky: http://forum.xda-developers.com/showthread.php?t=1134975
This is what happened:
I tried just about anything, nothing worked. Then I saw a reply in this thread someone mentioning you should plug in the usb cable, push both volume keys and then maybe it could work. But of course, mine didn't.
Then I started experimenting, what did work was this
- take out battery
- connect usb cable to laptop
- push volume down + home simultaniously and then put battery in
Now i got into download mode (yellow robot and triangle + warning not to turn off target) and with Odin I was able to start the phone.
I then found out that the power button was indeed broken!
Phone works like a charm. Only thing is when I have a dead battery that I have to use Odin to start the phone. I will seek for a way to fix the defective power button.
Hopefully it will help other people with this problem!
BTW, thanks all for all the help

[Q] Wont stop shutting down

after receiving my tablet for Christmas everything was working great all day the battery got low so i put it on the charger and then went to see a movie. After returning from the movie i picked my tablet up and saw that it was at 99% charged and a new update was available. so i started updating it and the progress bar got about 3/4ths through when it froze, so i powered down and restarted it. After restarting it i noticed that my battery was at 15% and the screen kept freezing on the lock screen. when ever i get it unlocked a message will pop up in the middle of the screen saying powering off immediately. can anybody here help me?
below the USB port is a reset pen hole. Try to reset the device by pushing a paperclip into the hole.you have to push hard holdit in firmly and then power on device.this should run recovery.
If not because its new I would call acer.
now it wont get to the lock screen, it just goes to a black screen and says power off, shutting down but still wont shut down
its defective take it back to the store.
If the pin hole will not reset it.
Make sure the power button shows being charged or charging.

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] My Aquos Crystal appears to be bricked after complete discharge

Hey everyone,
I don't know what happened wrong with my interaction with AQUOS, but the phone appears to be bricked.
Here's what happened.
Bought my phone from Boost, successfully switched carrier to Ting
Have been using the phone for more than a month without any problems at all
Yesterday, I left the phone without charging and it fully discharged
I plugged it to charge and came back to turn it on after a few hours later. This is when I noticed it wouldn't turn on.
I tried a couple things: holding the power button for a long time, and a hard reset (volume down button + power button). But the results were the same.
The screen doesn't turn on. While holding the power button or power + volume button, the only feedback from the phone is a series of prolonged vibrations (~10 seconds) separated by a brief pause (~1 second).
Have anyone experienced this problem?
Any advice/insight into this problem would be greatly appreciated.
I've had similiar issues with tablets where it completely drained and wouldn't charge via USB. At most it'd just give off a single vibrate and then die before even flicking on the screen. Try this, plug a USB cable in for a full 24hours before you hit the power button. Then give it a try. If it pops on to the screen where its charging after that let it get a full charge before fully powering on. Hope this helps and also hope its not due to the switch to ting.
Best of luck
PHONE OFF
This could be due to a bad usb connection. some usb when broke will actually discharge your phone or tablet so try to use a different usb. PLZ POST BACK IF THAT DIDNT WORK I HAVE MORE SOLUTIONS
