I upgraded to the latest 9700 OS (.862) and since then I have been having trouble with my lock key (upper left) which works to put the phone into standby mode, but doesn't work to take it back out.
I was hoping a full wipe and then a clean install of the OS would correct the problem.
After the OS re installs to I need to restore the back-up file to my phone, or will the re-installed OS already put back everything that was there before/
It won't and many like to use apploader. One should make a back-up file, like you did, and make a 3rd party app back-up. I like Crucial's method and make a 3rd party backup file every month or so to be safe. That said, I'm a little old school and lazy so I use DM 4.6 to upgrade my OS's. It does a nice wipe and load - and saves and reinstalls apps, data and settings. Never had a problem with it over years and multiple loads.
