I'll try when I'm at some place where I don't connect to any wifi because I have 4 access points configured at home and I'm too lazy to reset those in my phone
I cleared my AP ( forget wifi connection ) and re-enable it after root was set up.
You do need to shut off both wifi & mobile network for this to work. I'm guessing the software spoofs an OTA so if you have networking turned on, the software wouldn't be "downloaded" correctly.
