Hold off on calling me crazy for a bit. You might also remember me for damaging a tiny part (touchscreen ribbon cable) (http://talk.maemo.org/showthread.php?t=87274).

I'd just gotten my replacement N9, and it was going well for a few days, so it's time to swap the case to my sexy blue one!

After that, starting *either* phone with the old, non-responsive screen works. Starting either phone with the "working" screen results in a boot loop.

I understand that this isn't much to go on, but any ideas?

"Boot Loop -- Caused by end user, breaking his hardware when trying to swap the case." - sounds more like the correct topic.

You could of course try to disable watchdogs that reboot the device on hardware failure. (search the forum for flasher parameters).

Good news, everyone! (because you were all waiting with bated breath, right )

It seems that the boot loop was caused by an issue with the proximity sensor. Just by not attaching it the phone boots and runs just fine. I miss the standby screen and all, and doubletap to wake doesn't work... But it's a small price to pay (and proxy sensors are cheap!)

Maybe someday this will help a poor, clumsy soul like me.

can you please explain this a litle better? thanks
