My phone won't turn on and when i connect it to the charger sometimes it shows the charging icon and then goes into a loop, and sometimes it shows the charging icon one time only and then it dies.
Also if i try to boot into download mode, it works but it stays for like 10 seconds and then reboots, so i guess maybe the power button is faulty and always pressed?
What do you think?

Today I picked up may Nexus 7 and noticed it will not turn on. I let it charge for an hour or so, but then when I tried to start it up, I saw just a black screen. The screen turns on (backlight turns on), but still just a black screen. I read something on the internet about pressing the power button for a full 30 seconds, so I tried that. This time, I got it to flash (for a fraction of a second) the word "Google", and then it was back to the black screen of nothing.
I've never rooted, never tried to do anything fancy with it. I've factory resetted it once after an update to the OS happened.
Is there anything I can do?
You sure it gets juice? Does your charger feel hot after charging some time?
I had this to once, but got it fixed by holding the power button...

Sounds like a charging /battery issue if the 30 sec power didnt work.Did you try a different charger?
Some people have reported weird issues like this that have been rectified by a prolonged charging.
Thanks
It acted strange, but it came back from the dead:
It said "google" for 10 seconds, then a few seconds of black screen, then another 10 seconds of "google", then it booted just enough to tell me that it was going to shut down because of low battery. I let it charge another hour and then it was fine!

Quirky little buggers aren't they? Mine did it once and not since.
I just goy my N7 today, plugged in the wall charger, and I'm stuck at black screen, I did the 30 secs hold power button but it's still and black screen. Also I tried this:
1. Plug-in your dead N7 to a wall charger. (Jump immediately to step 2.)
2. Immediately after plugging it in, press Volume Down and Power at the same time.
3. Once in the bootloader menu, use Volume Down until you see “Power Off Device.”
4. Choose that option with the Power button.
5. Once your device is off, unplug the charger and then plug it back into the device.
Still at black screen, any advice???
I'm sorry for posting in this old thread.

I just solved this, I opened my N7 to check the battery and it turns out it wasn't correctly connected... Just unplugged it and plug in again correctly to make it work!

Boom!
I was having the same problem. Plugged it into a power source, backlight would come on with a black screen. Got it to show the Google splash screen a few times, but it just wouldn't boot. Tried ADB, but it wouldn't even acknowledge the thing was connected to the PC. I tried a pile of stuffs. Then I read this post. I never thought to check if the thing was actually connected, it wasn't!
Fully functional device now. Thanks for the idea! :good:

EDIT: I got it working after using the phone to charge for a few minutes
not sure if this fixes or helps anyone else but i got bootloader working
Same thing is happening to me. Two days now. I have followed all the instructions i found online saying
Drain off all the juice from your Nexus 7.
Connect your dead Nexus 7 to the charger and press the Volume Down and Power Button simultaneously. By doing this, you’ll head over to the Bootloader menu of the Nexus 7.
Scroll down to the “Power Off Device” option with the help of Volume Down Button.
Select it by tapping the Power button and disconnect the device.
Quickly connect the device to the USB charger again.
You’ll now see the Battery picture on your screen making your device working again.

However when i get to the bootloader i cannot scroll through the options or select anything. It just says "Start" and none of the hardware buttons respond.
When i do let it boot as above poster said it saw connect to charger and shutting down
weirdest thing is that it says "Connect to charger" and if i jiggle the usb it changes to "Charging 0%" but shuts off
I've tried multiple cords and chargers so the issue seems to be with the nexus
i'm at a loss and i've had the device since launch so returning it isnt an option..
any suggestions or help is greatly appreciated
Hi all,
My TPT this morning for some weird reason stopped turning on. I plugged it into my dock. When it's in the off state it shows the charging logo. But when I go and turn it on, the screen stays black with no Lenovo bootup logo. The red dot in the back of the tablet however, is on when I switch it on. I initially thought that the power drained but I've been charging it for an hour and it still doesn't boot up. Any suggestions? Thanks
Press the tiny button next to the SD-card and then try and start the TPT. You might be in bootloader.
Otherwise, maybe your display cable became disconnected inside. Easy to do or fix if you've opened it up.

Tried resetting, no dice.
Also I don't think its a display problem. Since when its off and I plug it into my dock the charging logo does show up for 5 seconds. Also, when I turn it on, there's no vibrate that the TPT usually does. I noticed that the red light only stays on for maybe 10 seconds then goes dim again

Okay so this is definitely weird. I just plugged it into my PC and via USB and it actually started up! But when I unplug it from my PC it acts the same as before... battery indicates a full charge in android though...

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?
Hi
Suddenly when powered off, I saw that when I plug in the charger, the battery icon pops up in the middle (as expected) the charging icon comes and that's it. It just shows a empty battery with a lightning icon. The weird part here is that i'm unable to turn the phone on the normal way and if I unplug the charger (even for minutes) the empty battery icon stays on and still can't turn on.
The only way to turn the phone on is home+power+vol down and when in download mode, choose cancel then restart.
I'm rooted on a custom rom, but haven't really changed anything.. Tried formatting and reinstalling everything.. Not seem to fix it.
Any ideas?
No problems on mine. Turned it off, plugged it in, got the battery icon with the percent of charge and three dots moving up from the bottom of the screen to the battery image. Pressed the power button for a couple of seconds, and it powered up like normal. I'd raise it with your ROM developer.
