[olpc-help] Diagnostic hangs or shuts down after touchpad test

[tchomby]

Ok, so I had it right, once I got the developer key and unsecured my
xo I was able to follow the manual firmware upgrade instructions and
upgrade my firmware to q2e22, then I booted the diagnostic mode and
confirmed with the keyboard diagnostic that just my left alt key was
sticking, then I followed the stuck keys guide on the wiki to disable
that key, and all works now.

Can I secure my xo again now? I prefer the secure mode boot screen.
Presumably I can secure it just by removing the developer key file
that I placed to unsecure it. But if I do that, will it still boot my
developer firmware version?
