Connect over ssh
NEOS uses private/public keys for authentication. The first step is to download the keys. They can be found in the neos release zip: https://github.com/commaai/neo/releases/tag/swag.
SSH on NEOS runs at port 8022. So after you downloaded the key you can connect with the following ssh command:
ssh -i /path/to/id_rsa -p 8022 root@<ip of eon or neo>
OTA Update Procedure
Having issues updating NEOS to v4? The following instructions may help you along. At this time, a locked bootloader causes a reboot loop. Unlocking solves the issue.
