http://forum.xda-developers.com – Hi all I have looked at the Note 2 Tool kit in the rooting section and wanted to ask a quick question, i have a note 2 on o2 in the uk, all i want to do is to root the phone but keep the standard ROM for now, will this tool kit allow me to do this, im a bit concerned as one of the options talks about "flash insecure boot image & Root phone" is this the option i need to be able to transfer apps to SD Sorry again for the newbie question but we all have to start somewhere :o Pete (HowTos)
