[Nexus 5 General] kojak1989:
There is more than one way to flash these images. Each give the same results, but the first is for lazy users :D

Method 1

. Easy method.

★Power off your phone.

★Boot it in fastboot by pressing and holding Power Button + Volume Down at the same time.

★Connect your phone to your PC through your USB cable.

★Execute the flash-all.bat script (for Windows) or flash-all.sh(for MAC and LINUX) in the folder where you extracted the factory images.

**!!** For MAC: You'll have to edit the flash-all.sh, and add "./" before every fastboot command.

★Wait for everything to flash.

★After everything finished, select "Recovery" using the volume buttons.

★When a small dead Android appears, press Power Button + Volume UP.

★Select "Wipe data/factory data reset"

★Reboot. Your phone should be stock. :good:

Method 2

. Long method (Same thing actually, but I'll mention it, just in case)

★Extract the image-hammerhead-krt16m.zip somewhere easy to access (On C:\image-hammerhead-krt16m for example). You will have the following files:

★In the same folder, from the original archive, extract "bootloader-hammerhead-XXXXXX.img" (

rename it to bootloader.img

) and "radio-hammerhead-XXXXXX.img" (

rename it to radio.img

)

★Power off your phone.

★Boot it in fastboot by pressing and holding Power Button + Volume Down at the same time.

★Connect your phone to your PC through your USB cable.

★Open a CMD window.

★Type the following commands, in this order (If you have a different folder, change the path)

fastboot flash bootloader C:\image-hammerhead-krt16m\bootloader.img
fastboot reboot-bootloader
fastboot flash radio C:\image-hammerhead-krt16m\radio.img
fastboot reboot-bootloader
fastboot flash system C:\image-hammerhead-krt16m\system.img
fastboot flash userdata C:\image-hammerhead-krt16m\userdata.img
[B](Note: this command will wipe your device (including \sdcard), EVEN if your bootloader is already unlocked.)[/B]

fastboot flash boot C:\image-hammerhead-krt16m\boot.img
fastboot flash recovery C:\image-hammerhead-krt16m\recovery.img
fastboot erase cache
fastboot flash cache C:\androidimage\cache.img

★After everything finished, select "Recovery" using the volume buttons.

★When a small Android appears, press Power Button + Volume UP.

★Select "Wipe data/factory data reset"

★Reboot. Your phone should be stock. :good:
