Nexus 5 is not passed on animation. No recovery mode starts

Question

Hello to everyone in the com, I have a big problem with my Nexus 5, the problem is not on, does not pass the boot animation turning green with red balls, yellow, and blue. It stays there infinitely or until the battery runs out and the same goes if I want to turn into recovery mode does not know what to do. 

This was after doing a wipe data, while in the process wipe data froze, then suddenly trailed off and restart was already with this problem. No longer started over. I do not know what to do if I can not even access recovery mode more 

Oh and whatever had not yet rooted or had a modified ROM. It was in KitKat 4.4.4 

Please it is urgent if they know that I can do. Thank you.

Answer 1

Follow these instructions: 

 

1-Download this: http://www.wugfresh.com/nrt/ 

2 Install it, I start it and configure it "Nexus 5 with 4.4.4." 

3 Connect the PC to the phone. 

4 Select "soft-bricked / bootloop" to the right and hit flash stock + unroot ". Wait. 

 

If it does not work, try this first mirate requirements: 

 

Having the development environment with the Android SDK installed. Failing that, we may have just the adb program 

Having unlocked bootloader on our device 

Having our drivers properly installed device. 

 

Leaving you to access the bootloader, this will serve you. 

 

ADB: http://cdn.androidcentral.com/sites/androidcentral.com/files/uploads/tools/android-tools.zip. Unzip after: 

 

INSTALLATION: 

 

1-Download this: https://developers.google.com/android/nexus/images and extract it. 

 

2 Copy the extracted to the folder where you unzipped the ADB file "which I have set before installation" file. 

 

3 With the device connected to pc with usb debugging and enters the bootloader mode "vol up + vol down + power". 

 

4 Open the "flash-all.bat" file on your pc and wait.
