did a pull wipe and dalvik
formatted system
then i wanted to flash the files
and without purpose flashed the second one first!
NOW
my phone wont boot... no recovery.... no bootloader and not fastboot!!
its suck at the google logo!!!
but whats wierd ist that at that google logo the PC sees it and also does toolkits!!! but no ADB
please if anyone has any idea how to get this running again please help me out!

Hold Power until it turns off then release the power button and press "volume - " and power at the same time and keep holding both.
What happens then?

Try to download this toolkit:

And choose flash stock.
I don't know if it works but you can try.
Also, alot of people get stuck and can still can get into bootloader try every possible way to get there because if you can access bootloader you can fix it with ease.
Did adb work before? If not it might be your drivers so fix that if it worked before you don't can access your phone with adb while on the google screen.
Good luck!

Can you access download mode by doing volume up and down with power?

Your battery died.
You need to put it in the charger for some time, the red light will go away eventually. Or try ro charge it with your computer or car.
BUT before doing that I THINK you must let it completly drain, so just let it the way it is and try the above tommorrow.
I'm not sure though so another member here needs to confirm this!

battery died indeed (probably fully discharged)
Try this:
1. just leave it charging for +- 30 min and check if it 'running' again (battery icon on screen).
and/or
2. hold the power button and then plug it in to a power source. Be patient because it may take up to 30 seconds for it to boot.
If it's working again and battery is full but system is not booting, try booting with volume- + power buttons and flash everything again (e.g. android 4.3) with fastboot.

thanks but No Chance!! the batter is full!!! if i tun it on with vol + or vol - or vol + and - ! all i get is a blinking red LED

I got a red light, not flashing ubuntu, it was running antutu with less than 30% bat, and OC. its all about battery.
What i did....
Plug my N4 to the wall charger all night long. After that i plug off and there was the same red led. I went to my job, on my way, i plugged into the car charger and....woalaaa , suddenly the red light turn off, pressed the power button and it start normally.
Do the same,but when you try to power on, do it pressing VOL- and power button to start on bootloader cuz you dont have an android system mount on it. Then Flash factory image vía fastboot.
I got that red light thing twice already OCin. And that work for my in both cases
Good luck

Red blinking LED is a battery voltage problem, best way people have found to solve is to use a 3rd party charger for a day or so then try again even if you think it's full.

Tried going into boot loader tablet wont power on

I tried going into the booloader by pressing power keys and on button and nothing happened. Now the tablet wont respond to anything, and I cannot turn it back on. Any idea what happened?

Should be vol down + power keys. Also put it on a charger, perhaps it is just drained. If battery is too low, it won't boot.

Vol down + power key allowed me to turn it on. thanks.

If anyone else has this issue and the above does not resolve your issue. Charge... Then hold the power button for 60 seconds. Should boot.

Yea I tried this last night. Before 15Q it was the standard VolUp + VolDwn + Power. But it won't even turn on trying that now. I could turn it on, bootloop, and hold power to force a shutdown... but couldn't get into bootloader.
I kept screwing with mine and used just Power + one of the Volume buttons and it booted directly into my custom recovery.
Mine was fully charged. Mine was bootlooping and I could turn it on with no problems but couldn't get into the bootloader AT ALL. Luckily I had a custom recovery on there to ADB Push files over.

It VolUp+VolDown, it is Power+VolUp for recovery and Power+VolDown for bootloader
Has been that way since initial release, though sometimes you get lucky pressing both and it gets you one or the other.

Nexus 7 cant turn on. THE MOST IMPOSSIBLE PROBLEM EVER

Good evening!
My nexus 7 doesn't response. I installed the Ubuntu 13.04 desktop preinstalled version for nex7 and used for an hour (i dont know exactly)
In the ubuntu i get the gparted witha apt-get and created a new partition with 29gb storage because the system only saw 6gb. After this i clicked the reboot in the os and After shutdown the device cant turn on. No flashlight, no bootloader... NOTHING
I tried the all key combination but nothing. I took off the back of nexus7 and reconnected the touch screen and the battery but nothing.
The device is not responding to power button, not responding to charging (also nothing flashlight or something else)
What i should to do? Please help, this is the most difficult problem in this device history..

There r only 3 solutions
1) Charge your nexus 7 for at least an hour
2) take out the battery and push it back in
3) hard reset your nexus 7 or keep holding the power button for 60 seconds

[Q] Nexus 7 (2012) refuses to power on after battery drain and subsequent charging

I own a Nexus 7 2012. It got full discharged over the weekend. So i put it for charging and wait for several hours. The tablet won't boot and neither any big battery symbol would come on the screen. I kept it for charging for more than a day and still it doesn't power on.
Tried power + volume down combination and nothing.
I am using original charger and cable and they work with other android phone so they are not defective.
How do I revive my nexus 7 ? Any suggestions ?
The tablet is not rooted, if it helps in any way.

Hello,
Below is listed a few troubleshooting steps that can power on a Nexus 7 when the battery has been completely discharged:
1. Charge the tablet from a wall outlet for one hour > Unplug your Nexus 7 > plug your Nexus 7 back in within 10 seconds > Hold the power button for 15 seconds.
2. Connect your Nexus device to a computer’s USB port while the computer is on. > After 10-15 minutes, disconnect the USB cable from your Nexus device and reconnect it within 10 seconds. > After 1 minute, check to see if a battery icon appears on the screen. > Press & hold the Power button for at least 15 seconds to see if your device turns on.
3. Press & hold the Volume down button. At the same time, press & hold the Power button for at least 10 seconds until you see an Android robot and the word Start on the screen. > Press the Volume down button until the screen shows the option to Power off. Press the Power button to select that option. > Disconnect the charger and reconnect it within 10 seconds. A battery icon should appear on your screen. > Once the battery icon appears on the screen, allow your device to charge for at least 1 hour before turning it back on.
I hope one of the steps listed above helps you power on your Nexus 7. If you need any further assistance please email me and place case number N140904697 in the subject line for reference.

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.
