Issue/Symptom
1. Firmware got locked
2. All data is not allowed for access.
Solution
Following steps were performed for this case:
1. Back up ROM: this should be the first and universal step for all Seagate cases.
2. Unlock SA: generate unlock ROM - write unlock ROM - power off and on - send unlock key.
Pls note that this model come with the LM structure, so we need to select LM series to read ROM. And
the Unlock ROM can only be created manually at present. The program will be able to generate it
automatically in next update.
