Hello
I believe for the ME9210 the only supported carrier board is the "new" one, but I just need to check first. On the carrier board there is either one large off-white block of switches or there are two. Also down by the power plug, is there a MFG P9 block of four pins or not?
Where I am going here is that there is a documented method for recovering a board but it is different for the old VS new carrier board. So I want to ensure I know which one you have.
See the following:

The only thing I believe there may be a mistake. On the new board, on header P3, I believe you want to jumper 18 and 20, not 16 and 20 as described in this document.
Also you'll need to have the stdout serial port connected to a terminal emulater such as hyperterm, so you can see the output. I use serial recovery. It is a little slow but does work. Whatever you do, do not remove power until you are sure that recovery completed.
Also you may want to ensure that whatever you are uploading includes an FTP server.
