Wink [Q] Installation of Stok Rom (Xperia J)

Good afternoon everyone! Not notice my English. I am Brazilian and not speak English.

So in this topic do not use abbreviations to facilitate the translation. Thank you!: Rir:

I wonder what I do to install the stock rom on my Xperia J. Which programs I use for flashing it?

I tried Flashtool, but my computer is 32 bit and did not run it. So if anyone can help me install Flashtool (emma is not), I would be very grateful. Thank you!
