My 550 and two 768s (I think) even my old original 'EasyZapper.com' remotes all work quite well on rechargable NiMH batteries.
Last night the current set in the 550 apparently died and somewhere along the line the remote now boots to 'Safe Mode' Recharge batteries overnight (200ma charge rate, nice & slow) Still, remote boots to 'Safe Mode'.
So I try this trick, pressing the number two button, while powering on (which other threads indicate this how one upgrades the firmware. And it worked a treat.
Thankfully now I do not have to plug into USB, and go spelunking the logitech site for my profile, and most importantly no call to tech support.

I just wanted to update this thread in case anyone with
a similar problem stumbles across it. My rechargeables
just died after another month or so and I had the same
problem as I reported in my initial post. After fiddling
around for a while I stumbled across a solution that appears
to work every time. When the remote locks up all I have
to do is take the batteries out, put three fresh batteries
back in, then hold down "2" while replacing the last battery.
No idea why it works, but it does.
