Hi X10iUser -- well the saga continues, but in a good way... installed the original SE Home app from your list and it broke the dark theme (of course it did!), so a quick jump onto the market and a reinstalled LP fixed the problem, BUT, only after I cleared the Dalvik cache, I guess I tried/retried 6 or 8 times to reinstall LP, it failed each time with an 'Application not installed' message. Quite by chance and much rummaging around the net, I came across an obscure and unrelated post that mentioned the Dalvik cache, until then I had no idea it existed.
Anyway, Titanium Backup (thank you kindly) has a clear cache option which removed the offending fragments and LP then installed.
I pass this on, in case another noob follows my rocky trail...
And now a further question if I may, I have dl'd your X10RM theme because I prefer the font etc, can I custom install this over the new and shiny Eminence or might this break things once more? I have made a backup using xRecovery, but I'm loathe to jump in again without a little prior knowledge.
My X10 is looking very smart and running without issue, up to this point.
First time I've been excited about a phone since my original XDA back in 2001/2.
