Those well-detailed instructions I used to install the multilang ROM. Then, vRoot worked fine. However, after that, it doesn't seem to do the job. What happens is this:
1) I launch vRoot.
2) I connect my phone to my PC (Win7).
3) My phone asks me for permissions. I check Yes on all of them.
4) Then my phone reboots itself. That's where I think it goes wrong.
5) After that, vRoot keeps saying "Waiting for device". The longest I have waited has been about 15 minutes. Although I'm just another n00b, something tells me it ain't happening.
