Title says it all really, trying to soft re-set just confused me more. Is there an idiot proof video/step-by-step guide? Better yet, can somebody talk me through it, start -finish, I'm rubbish with technology.
The Vodaphone store I bought the phoned from is an hours' journey each way by bus and takes up best part of the day.
If it isn't clear to you, HERE is a web page that explains the same process with pictures.
"Completely messed it up" covers a lot of possible problems, forgot pin, filled the memory with too many apps, I don't know what... So this may NOT fix it. If So, I'd need more information as to EXACTLY how it got that way and maybe I could help you fix it short of the LAST RESORT which would be a "Hard" reset, but that LOSES al your personal data and apps by putting it back in an out-of-the-box state, where you have to set it up (basically as a new phone) NOT the preferred solution...
This Web Page goes over how to do a HARD reset (factory reset) and This Video goes over one way to do the Hard reset.
Good luck.
Again before taking the FINAL RESORT you might tell us more so maybe you don;t have to do the factory reset.
