hello everyone some time ago on my dm800hdsev2 I loaded openspa and now to return to openpli gives me bad sector ....and don't let me charge anything anymore what can I do?

10:57:14 box type: DM800SEv2
10:57:56 Calculating checksum...
10:57:57 Uploading file to box...
11:15:03 box is flashing from its memory...
11:15:06 Flashing failed (!!! 005 too much data (or bad sectors) in partition 1 (end: 00100000, pos: 00100000)), box will be unusable now!!


thank you all
