Right the permissions thing turned out to be an issue with Superuser, dunno why. So replace the su binary from SuperSU (http://forum.xda-developers.com/show....php?t=1538053
) into my SUME pack and install the Superuser.apk by;
adb shell mount -o rw,remount /system
adb push Superuser.apk /system/app
as for stripping back the Applications, I've got it down to this as bare bones
adb pull /system/app backup\system\app
to backup system applications before you do anything
I found if you do delete any applications and then android gets stuck at the logo, just adb push them back and it'll boot without reboot when you've got the chain right.
minimum applications needed for boot are;
A few odds and sods missing will make settings close, but it's trivial stuff. Personally don't like the sound of Fused Location, but it won't boot without it and I haven't seen any dodgey traffic from it (yet).
I recommend installing Droidwall with adb push /system/app, before installing games.
And modifying /etc/hosts with 127.0.0.1 to certain you know whos and advertisers.
Some of my personal choice replacement applications (so far);
Total Commander over ES file explorer.
Opera Classic over the inbuilt browser (although I'm still trying to remove the default search engine).
