Flashing with RF Connect

[wibble]

I guess it depends what you mean by 'should' ;-) If I go to the menu on InfiniTime 1.9.0 and pick About it tells me I have bootloader 0.0.0 while if I reboot with a long button press the bootloader tells me it's V1.2.3. I think my bootloader is actually a late release candidate from testing shortly before the 1.0.0 bootloader release, but I'd have to check my notes. The releases and update instructions are here:

If the back is glued on I'd stick with the bootloader that's installed.
