So I have a similar issue.
But I did not do anything screwy from the console messing up the flash etc. So I believe my pineapple can be recovered.
I have the "Bad magic number 0x73797375" message when the pineapple tetra boots.
I can boot it and flash a new bin file via the web gui at 192.168.1.1, but when it boots I get the bad magic number.
What can I do from the uart console to fix this?
Should I try to put the bin file on a tftp server (host which the tetra plugs into)??
is there some other way to clean / refresh / reinstall the original firmware on the device?
