  1. thanks. it really works to me :)

  2. I second what trio said. All went without a hitch, and I was really surprised that I didn't have to reinstall or restore anything (but I did make the backups as you advised) Thanks very much for this!

  3. We always do back-up all important files, even flashing with a non-wipe stock. Flashing is a bit risky and accidents may happen sometimes, it is better to be prepared than sorry if bricks occurs while flashing.
