Fix the power button
You could attempt just plugging it in and unplugging it a bunch, I have had some phones in the past that this works for, but if you are rooted I know at least one version of twrp recovery caused my phone to power on when plugged in and it would boot to recovery, from there you could just boot to os. Of course you would still need to get it to power on at least once first, so my guess is you need to fix the power button

Have you tried holding the button down for awhile? Like 15-30 seconds?

open phone, remove the power button board(its connected to the mobo with 2 golden pins, they just contact with mobo, so you can just lift away), and do a little short on 2 golden contacts on the mobo till phone turns on

Yes, i tried to hold it about 2 min, i'm sure this is hardware problem

n7 just died, how can i wipe data before exchanging??

My N7 just randomly died. It's been working great for a month and now suddenly won't turn on. The battery was very low and it probably shut down from that. But after plugging in to recharge, nothing!! No power, won't turn on, has no indication it's charging ... totally dead. I bought retail but if i return it now, my data is not wiped. I'm afraid that after i exchange it, anyone either at the store or at google/asus that gets it back and gets it turned on will have access to all my accounts.
any suggestions?
does it connect when you plug it via usb?

It's 100% dead so it doesn't connect at all, not power not usb. Very weird, it's had zero issues until now and it just randomly died ... no trigger
Since you didn't provide info on how you were trying to charge it...
o are you using the OEM charger and cable?
o how long did you let it charge (let it go a couple hours)
o When you try to start it up after letting it charge for a while, press and hold the power button for a long time 30+ seconds
If you can't get it to ever power on, you will never get the data off since that is the only way to access the memory on the device.
I'll just leave this here...

Nexus 7 won't boot

I noticed my nexus 7 battery have drained out quicker today and when I got home it could not turn on and is stuck on the black screen. It is rooted. I didn't do anything except restore an app with titanium backup. Please help

Try plugging it into a different charger and see if it powers on, or into a computer and see if it is recognized and just acting weird.
Try holding power and volume down and maybe itll go into the boot loader... if not might have to take it back
Check this post. May help.

Not really actually. I helped my friend with hardware issues..he had to send his 7 in so we used wug fresh toolkit to flash stock and unroot then OEM lock the boot loader... google/Asus had no idea. I have also heard that if its bad enough shape(like won't EVER turn on) then they don't know I assume they somehow get the boot loader back on there and just reflash firmware.

Charge it for 2 hours then boot it up by holding the power button down for exactly 30 seconds.

[Q] Help: Bricked Phone

Hi
I managed to bricked my N4 after running antutu. Is there any way to revive the phone?
I can't start the phone. If I plug the phone into my wall plug, I see constant red LED light.
I've tried the following
1) Press vol down + power button - Didn't work
2) Press vol down and up + power button - Didn't work
Is there any other way methods?

I am afraid that RMA is your only option
Sent from my Nexus 4 using xda app-developers app
Hmmmm and you just needed to make new thread without searching as there was someone yesterday with exactly the same problem and of course there were million more before you. You have 3 options:
1. Leave it to charge for maybe a day or leave it for say a day and then charge and see if that helps and then charge.
2. Open the phone and disconnect and reconnect battery terminal. There should be YouTube video from one of the members.
3. RMA

Seems you have the red light of death ( RLOD) . Can you get into the boot loader?
Plug in the charger, hold power button and volume down button. If you can get into bootloader then use the volume key to select "power down" and use power button to choose that option. Then just leave the phone plugged in for a while.
I've had it only take maybe 5 minutes and other times take an hour. Try turning it on, if it just vibrates then shows the Google screen and reboots then redo the steps and leave it plugged in and let it sit for longer

Check the file you flashed. Sounds like you flashed a ROM not meant for the nexus 4 like a nexus 7 ROM.
If that's the case you are bricked and only a JTAG will save it.
Sent from my Nexus 7 using xda premium
If you can get in bootloader:
download the ROM from computer (correct one)
get into recovery
mount usb storage
put ROM in phone
flash rom
wipe
reboot
you might have to hold power and volume down for awhile.. 10+ seconds
You posted this in the wrong forum btw.. next time Q&A would be appropriate

Looks like that is a gs2 ROM. Only way to save it is JTAG.
For future reference only flash Roms made for the device you are using.

See if you can power it on in the download mode. I forgot the button combo, but it's volume up or down (or both) and power.

[Q] Lg G2 won't turn on

First thing you should probably do is let charge up then see what works and what doesn't......then the help can come
Its been plugged in for about 8 hours. The phone gets a little warm so I thinks its charging but I can't tell. The screen was working yesterday so I don't think the LCD is broken. Plugging it into the computer gets no reaction.

No the PC doesn't recognize the phone at all. I tried installing the Lg Mobile support tool and the drivers but none of those can detect it either.
