24 Using the System
3.2 System Recovery
You will need a Linux host PC (Ubuntu is recommended) in order
to flash your client device with a new system image. Complete the
following steps on the client before performing the host PC steps.
Client (DLAP-301):
1. Connect the OTG cable to the USB 2.0 port.
2. Press the reset and recovery buttons at the same time.
3. Press the power switch.
4. Release the reset button.
5. Release the recovery button.
Host PC:
1. Install Python 2.7, python-minimal (or equivalent pack-
ages) and qemu-user-static on the host PC.
2. Connect the host PC to the client via OTG cable.
3. Open a terminal on the host PC and run this command:
# lsusb
4. Look for “NVidia Corp.” in the output (an example is cir-
cled in red in the screenshot below). If found, the host
PC recognizes the client and you may proceed. If not,
double-check the OTG cable connection and perform
troubleshooting as needed until the client is recognized.

5. Run the following command in the directory that contains
your downloaded L4T file:
# sudo ./nvmflash.sh
6. Allow the update to complete.
