Hello User,

This means you changed the original password.

I will try again, but if you cannot unseal, you have to swap out the IC. There's no way to force unseal this part if the default keys do not work and you cannot unseal with the default keys.

Hello User,

On an unsealed pack, you can change the seal and unseal keys in the gg.csv file in the security section.

Have you changed the password by sending commands?
