 '''NOTE:''' Use mmcblk1p1 for SDcard and mmcblk0p1 for emmc.
-'''NOTE:''' I also found this way to do it from the board, but it could cause errors (see [https://devtalk.nvidia.com/default/topic/1021660/is-there-any-other-method-in-l4t-r28-1-to-update-dtb-file-for-tx1-besides-flashing-the-dtb-partitio-/ here]):
+=== Flash DTB from the Jetson device itself ===
-*'''TX1'''
+You'll need to generate signed/encrypted dtb files through the flash scripts and then flash it to the kernel-dtb partition of the Jetson device.
+. To generate the signed/encrypted dtb file follow these steps (tested JP 4.2 TX2):
 <pre>
-sudo dd if=tegra210-jetson-tx1-p2597-2180-a01-devkit.dtb of=/dev/mmcblk0p13
+cd $DEVDIR
+sudo ./flash.sh --no-flash -r -k kernel-dtb jetson-tx2 mmcblk0p1
 </pre>
-*'''TX2'''
+The above command will generate the following encrypted dtb file:
+<pre>
+$DEVDIR/bootloader/tegra186-quill-p3310-1000-c03-00-base_sigheader.dtb.encrypt
+</pre>
+. Check the partition labels of your Jetson device:
+<pre>
+nvidia@nvidia-desktop:~$ ls -al /dev/disk/by-partlabel
