The last time I tried EasyMiNT, it took several hours and it failed to install the AES properly ( This is a known issue and it has been fixed ).
The other day I re-tried it with the CT63 and it took minutes... I recon 20 minutes absolute maximum, although I was not timing it I have to say.
I have also now tried it on the TT and after a couple of hours I got bored... I am sure thgouh that it hung, but not sure... My TT at present only has 4+4MB so that might be a cause?
