It sounds like you have the new 4.93 software it may be a slightly different procedure than a straight recovery


DB Compatibility
- The database of V4.93 is not compatible with that of a previous version including the
V4.91 because of changing file system to YAFFS2/MTD.
- For changing file system, Boot S/W should be upgraded to V4.93.
- How to change file system refers to ‘OS7030 - How to change file system instructions’
- File extension of new package is changed from pkg to pkm.
- Download the database of the existing system before upgrading to V4.93 using DM.
- After upgrading to V4.93, upload the downloaded DB by DM.
