Cant help on the rooting help, but sounds like you got it sorted, but im just chipping in here and saying to not use the royal mail's simply drop recycle service, i was in a similar situation a few weeks ago and they seem to offer the best price, my phone was in great condition as it had been cased its whole life and had a screen protector, when i sent it off, i got an email back when they recieved it saying the screen was scratched and there was scratches along the back of the case. I replied back with a strongly worded email that there is no way the phone was in that condition when it left my hands. and ask for them to return it. got another email swiftly afterwards saying they would happily return the phone for a £15 postage and admin fee. Utter scam
