After the wipe process, the device showed BB-0015 error, after whichI tried on looking on solution which was given on Blackberry Knowledge Base (KB-34545), I followed the steps correctly bu in the end after extracting the device software, the link software showed that An Unspecified error has occured (A:0x00000049).
