I want to do exactly the same thing. where did you download the ftf file because in my case on MEGA it comes to 99% and just stops.

edit: downloaded via chrome. for some reason mozilla just stops at 99%.

    Yes, you are good to go. Flash .136 FW and wipe Data, Appslog and Cache. It is recommended to do that, if you will try to keep your data you can face many problems, just wipe everything and you will be fine.
