EXOS corrupted

[Njanyana_Buthel]

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.

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

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

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.

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.
