IMAGE_ATTRIBUTE_RESET_REQUIRED
AttributesSupported | AttributesSetting | Meaning
--------------------+-------------------+--------------------
0 | 0 | state is unknown
0 | 1 | state is unknown
1 | 0 | reset is not needed
| | to complete upgrade
1 | 1 | reset is needed
| | to complete upgrade
IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED
AttributesSupported | AttributesSetting | Meaning
--------------------+-------------------+--------------------
0 | 0 | state is unknown
0 | 1 | state is unknown
1 | 0 | signed and unsigned
| | capsules are accepted
1 | 1 | capsules are only
| | accepted after
| | checking the signature
For both bits AttributesSupported=0 does not make much sense.
IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED is a property of the current
image and should only be deleted by installing a new capsule.
A vendor might send you a special firmware image for unlocking your
device after registering as a developer. Xiaomi handled it like this for
one of my routers.
Best regards
Heinrich
