These questions surprise me, it seemed to me that you were an expert in mass configuration…
I have understand bad…
If you netinstall device without flag “Apply default config” (with -r on linux) or using “Configure script” int never run defconf
so password (on sticker) and other things are never set…
How to retrieve the default passsword if the label is damaged?
Use netinstall with this custom script… try to guess where you can read the password…
/sys id set name=$defconfPassword
