Yeah i worked that out eventually lol, perseus caused a boot hang and then i tried another custom, cant recall which one but i then got a joot, yet was left with problems of no wifi, no sd card read/write, apps attempting unpermitted actions warnings and lost loads of sd mounted apps. I then tried adams kernel, which solved a couple of the issues (wifi/sd card) but i still recieved regular error warnings for unpermitted actions.
I bit the bullet and reflashed the stock os, which as it happened, installed as an update, this solved all the issues and once that was done i decided to flash with the latest MGA 4.2.2 update.
Im considering moving over the the google edition 4.3 rom but im not sure i can be bithered to reinstall all my apps and settings.
