I'm having the same problem! I tried the reset of the remote with the power button while removing the batteries. My computer was able to recognize the remote again, but it failed a 99% sync like everyone else.

Got the 4 flashing lights when I cancelling the sync prematurely (on my Win7 x64 computer which is having problems recoginizing the remote through myharmony.com), that's what caused the blinking.
I hooked the remote up to my older WinXP x86 desktop and was able to sync the remote on myharmony.com, that got rid of the blinking lights and returned normal functionality.
I still can't solve of the driver issues under Win7 x64, which causes myharmony.com to fail to recognize the device.

Me too. Been working fine for 5 months and now just frozen with device lights flashing. This remote replaced a logitech 515 which was also cactus. Has anyone managed to get theirs working??

Just for the records, I've just spoken to someone from Logitech support services and it seems that this problem requires the remote to be replaced.
I'm wondering what if this happens when the guarantee period is over...

For those Harmony 300 remotes with the 4 Devices buttons flashing, try this, remove the batteries, then while holding the Number 2 button replace the batteries. Don't hold the Favorites 2 button but the Channel # 2 button.
