No, the instructions I gave was
download itunes from www.itunes.com
Install it on your computer and once installed, connect your iPhone to the computer.
Then choose Device, Backup and you can then perform the backup
Once the phone is backed up, please disconnect it and do the reset as I indicated.
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
Else let me know the results please.
