ah, bad md5 = not good file. i always use a download manager (it helps a lot), except for sites that don't work with them (such as the site twrp is on).
since it's downloading, can I recommend you read point E here: http://forum.xda-developers.com/show...2&postcount=21
that's how you're going to get the rom to your phone, so you can install it using twrp
Then once I am installed, erase cache and reboot?
Then return to the s-off with firewater and carry on with the guide...?
Thank you so much for helping me.
