Thanks, it works.

Also, don't forget you may need to bump over_voltage_sdram when overclocking, particularly when increasing core frequency which may end up driving the SDRAM a bit harder (at least on the Pi1, possibly not so much on the Pi2).

Thank you for posting that, as I've no joy with the (correct, 501) Pi2 image so far, not getting beyond the 4 colour screen.

However, I suggest if anyone finds this update method doesn't progress beyond the initial rainbow, check the existing overclock settings in config.txt, & edit or remove them, otherwise the result may be ARM register dumps for one or more cores, & frame pointer errors, etc. (I edited cmdline.txt to remove "quiet" so I could see boot progress)

It's working fine now thanks.

Thanks, yes, it's worth noting that a Pi1 overclock isn't guaranteed to work on a Pi2 (and vice versa). I'll mention that in the first post where I've added a migration section.

I was a bit worried actually about any consequences of the rather higher overvolt settings for core & sdram, than those suggested for Pi2! However, Raspbian stills boots & appears to work fine, as well as Kodi. It's reassuring, because, for example, as a Raspbian SD image (made for Pi2) works fine in B, B+, & of course, Pi2, it's easy to inadvertently insert a SD card with inappropriate overvolt settings into any RPi. If kodi eventually has dual Arch kernels, the same scenario would apply.

I see you've already updated Post 1; a very comprehensive post, thanks.
