# Auto Flash Orins using SDK Manager:

#### Step 1: Install pre-requisites and enter force recovery mode from [here](https://docs.nvidia.com/jetson/archives/r35.2.1/DeveloperGuide/text/IN/QuickStart.html#to-flash-the-jetson-developer-kit-operating-software)

<!-- 1. Download the latest Jetson Linux release package and sample file system for your Jetson developer kit from https://developer.nvidia.com/linux-tegra

3. Enter the following commands to untar the files and assemble the rootfs:

tar xf ${L4T_RELEASE_PACKAGE}
sudo tar xpf ${SAMPLE_FS_PACKAGE} -C Linux_for_Tegra/rootfs/
cd Linux_for_Tegra/
sudo ./apply_binaries.sh
sudo ./tools/l4t_flash_prerequisites.sh

1. Put your Jetson developer kit into Force Recovery Mode.

For Jetson Xavier NX Developer Kit:

    1. Ensure that your Jetson Xavier NX Developer Kit is powered off, and a 64GB or larger microSD card is inserted in the SD card slot.
    2. Enable Force Recovery Mode by placing a jumper across pins 9 and 10 (FC REC and GND) of the button header (J14), located on the edge of the carrier board under the Jetson module.
    3. Connect the developer kit’s power adapter to J16. The developer kit powers on automatically and enters Force Recovery mode.
    4. Remove the jumper from pins 9 and 10 of the button header.

2. Confirm that the developer kit is in Force Recovery Mode by following the procedure [To determine whether the developer kit is in force recovery mode](https://docs.nvidia.com/jetson/archives/r35.2.1/DeveloperGuide/text/IN/QuickStart.html#to-determine-whether-the-developer-kit-is-in-force-recovery-mode).

Open a terminal window on your host computer and enter command `lsusb`. The Jetson module is in Force Recovery Mode if you see the message:

    Bus <bbb> Device <ddd>: ID 0955: <nnnn> Nvidia Corp.

#### Step 2: Get SDK Manager and reflash

1. Get [SDK Manager](https://developer.nvidia.com/sdk-manager)
2. Select board and Jetpack version: 
3. Change the local folder names: 
4. Finally, this should complete the process: 

This will firstly download all the things on host system and the flash the orin with the selected jetpack, then install all the downloaded items to orin.
