The default system password is 707070. To change it, check the "Update Password" box and enter your old password (707070) directly.
Before upgrading, please read the upgrade instructions carefully and follow the steps.
Please note that, in addition to the initial power-off operation, do not press any buttons on the control panel during the process.
When upgrading, some cards would freeze; this was because I clicked too quickly. I turned off the power to the machine and restarted it, then reopened the software and tried again.
The boot image also updates automatically, otherwise the screen will be blank at startup.
