Unable to unlock simulink library blocks

40 views (last 30 days)
Simulink library block stuck as locked read only. When block is used elsewhere link has black box around it and can't be disabled for editing. Have tried unlocking and resaving library but won't "stick" have also gone into "Library Properties" and in history unchecked "read only". Still shows up as locked.

Had this happen to me recently.
1) Open the Library
2) Unlock it
3) Click on Diagram -> Unlock Links to Library
4) Save the Library
You should no longer have the black boxes in your model.

Thanks Moe, it took me a while but I finally figured it out. There is a difference between unlocking the library and unlocking the library links.

No problem man! Glad you were able to figure it out on your own
