    I was upgrading BD8806 from 12.3 to 12.5 then 15.7 but unfortunately my EXOS got corrupted on both partition. If I try to install EXOS from bootrom it failed with the following error :

    download: The image you attempted to load is either not a recovery image or it may be corrupted. Please try again.

    Running image boot...

    Where can I get recovery image or how to recover my MSM to boot properly.

    OK.. To get a recovery image you need to get a non-patched version of XOS. So if you are going to go to 15.7, go get BD8800-15.7.1.xos - To complete the rebuild of the image you need to boot into the bootrom and do the following:

    From bootrom:
    "configip ipaddres [i] gateway

    Thanks a lot, I manage to recover reinstalled the EXOS. The error message "download: The image you attempted to load is either not a recovery image or it may be corrupted. Please try again." was related to my TFTP server which was failing due to block-size, even after increasing/decreasing the size on the application. After changing the TFTP server, download was possible.

    So glad that worked out! The problem you ran into with the TFTP server I have had that in the past too... should have remembered it. I sometimes use PUMKIN tftp which will not work and had to end up using another free one from another MFG.

    This is a usual issue with some old tftp server. I personally use tftpd32/64 to avoid such painful problems.
