Code:
[root@kindle us]# showlog -f
120508:102649 ota[948]: E ota_check:validateOTAHeaderFailed:reason=deviceCodeMismatch:
My guess is that first error tells the entire story.
"Spanish" must be a different device code.
EDIT: A good question for lab126: Why didn't the ota updater bail out on the device code mismatch error, instead of trying to trash the system?
