Getting GetProp error that you don’t have the latest HHZ11k bootloader while installing a new custom ROM?

This is due to the fact that some of the latest custom ROMs require the latest bootloader. ¬†You can unroot your Nexus 5 to the latest firmware to get the HHZ11k bootloader OR there’s a simpler way, just use fastboot to upgrade your bootloader manually.

Step 1. To do this, simply put your Nexus 5 into bootloader mode (see video if you don’t know how).

Step 2. Download fastboot.zip and the HHZ11k bootloader zip file and unzip both files.

Download HHZ11k Bootloader

Step 3. Copy the bootloader image file into the fastboot folder.

Step 4. Open a command prompt for Windows or terminal for Mac/Linux.

Step 5.
For Windows, type:

cd Downloads
cd fastboot
fastboot flash bootloader bootloader-hammerhead-hhz11k.img

For Mac, type:

cd Downloads
cd fastboot
chmod 755 *
./fastboot-mac flash bootloader bootloader-hammerhead-hhz11k.img

For Linux, type:

cd Downloads
cd fastboot
chmod 755 *
./fastboot-linux flash bootloader bootloader-hammerhead-hhz11k.img

That’s it!
