ATTENTION!

Recovering a gateway will clear all contents on the device's main storage memory (HDD,eMMC).

Before continuing make sure you saved all important informations on the gateway to somewhere else before.

USB stick preparation

Take an USB stick with a size larger > 500Mbyte which is the minimum estimated size of a firmware image
The stick can be either USB 2.0 or USB 3.0 compatible. The gateway offers both options.
The stick must be formatted FAT32 and named "RECOVERY". The correct name is most important for recognition later.
Sticks of sizes >=64GByte can't be formatted FAT32 under Windows and more. You need a tool such as "HP USB STICK FORMAT" to do so.

The firmware image comes as TAR compressed archive
Use a tool such as 7Zip to decompress the file
The image directory starts with a root folder "." where you find all the relevant files in
Extract the two folders "boot" and "EFI" and the firmware file to your the USB stick in a 1:1 copy
The stick then looks like

Make sure the gateway is switched offf by pushing the power button on the front panel . The green power LED indicator will go off.
Plug in a keyboard in any of the gateway's USB ports
Connect a monitor to the gateway's DVI-I display port. Just use a 1:1 DVI cable only (don’t use adapters DVI-I to VGA or so, they will not be recognized by the gateway and the screen remains black)
Plug in the firmware stick in any of the available USB ports (USB3.0 is much faster and marked in blue)
Power on the gateway
The time the gateway beeps with a sound press key DEL on your keyboard. That activates the BIOS configuration screen on your monitor. If you are too late pressing the DEL key the gateway will detect an invalid USB boot media stick. In this case reset the gateway and start from beginning.
Use the cursor to move to the “Boot” option and then move down to “Boot Option #1”. It should be set to “UEFI OS: (P1: xxxxxxxxxx)" which is the HDD
Press return to open other options. Choose “UEFI: <name of the stick> xxGB”. DO NOT choose the option "UEFI: Built-in EFI Shell".
Move the cursor up to “Save & Exit” and confirm saving with yes. The gateway will reboot automatically.
The gateway will now boot now from the USB stick

Insert the USB stick and power the gateway
Optionally you may connect a serial cable to the serial RS 232 port to monitor serial outputs at settings 11500,8,N,1 on a terminal program.

During the update procedure you see console outputs on either the display or serial port depending on the gateway model in use. They can be ignored if passed with OK.
Let the update progress bar run to the end. The gateway will automatically switch off.
Important is not to remove the USB stick from the gateway else the update procedure would be executed again.
Power on the gateway again. Since there is no USB stick connected any more, the boot order will be reordered back.
Again you will recognize console outputs and you see the update procedure finalizing.
In case the the console output stops, the recovery procedure is finished. Gateway with display will end up in a netIOT screen with login
Keyboard and optional serial cable ormonitor are no longer needed for further operations. You can remove them from the gateway finally.
