[HELP] Can't flash Shield Tablet - Stock Firmware 4.4.2 i think topic

Hey guys,
I have been trying to flash my Tablet for a few hours now. I would constantly get problems trying to flash. I'd reboot and go into fastboot again and then it would flash successfully. This works for everything (boot.img, recovery.img, system.img) however i can never get userdata.img to flash correctly. I am using the steps from nVidia to do this. Ill post the steps here as well as the exact error im getting.
Steps:

SHIELD TABLET RECOVERY IMAGE FLASHING INSTRUCTIONS

To follow the instructions in this guide, you will need adb and fastboot.
These tools are provided as part of the Android SDK:
http://developer.android.com/sdk/index.html

Before flashing this recovery image to your SHIELD TABLET, connect your SHIELD TABLET
via USB to the PC where you downloaded this recovery image.

Next, put your SHIELD TABLET into fastboot mode using one of the following methods:
SW method:
- Boot to android home screen
- Connect the device to linux/windows system
- Open terminal (on linux); command prompt (on windows).
- Type "adb reboot bootloader" in terminal/command prompt

HW method:
- Turn off the device
- Press "Volume Down" -> "Power", hold "Volume Down" and leave Power buttons till device boots

To flash this recovery image to your SHIELD TABLET, run the following commands from
the directory where you extracted the recovery image package. If this is the
first time you have done this procedure, you must unlock the bootloader (see
below):

fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash staging blob
fastboot flash dtb tegra124-tn8-p1761-1270-a04-e-battery.dtb

Unlocking the Bootloader
Your SHIELD TABLET may have shipped with a locked bootloader. To update the device,
you must unlock the bootloader using the following:
- fastboot oem unlock
- Press the "Volume Down" button to select "Unlock bootloader" option on device
- Press the "Power" button to confirm the unlock. Your device's bootloader is now unlocked.
