Hey I desperately need someones help.

can someone please provide an answer/respond on how to work winscp or putty I'm totally clueless on how to work with linux/ubuntu and its commands.

My N9 is busted after meddling with Faster Darker Better Theme App. Currently my N9 cant go pass the black screen page that has 8 white cubes and 1 black cube that switches one after another between the 9 cubes (Could be a loading animation)

Additionally my phone is also stuck in the SDK setting whenever its usb is plugged in. I tried to find for people who are experiencing the same dilemma but ended to a dead end as these people aren't being answered/responded in a general way which doesn't really help.

according to the link it seems that I have to do this to get a fix but i cant get pass on the workings of these programmes.
I got to the part in Putty/winscp but cant seem to login.

from what i've gathered i think i need to enable some settings to grant me user access or something like that right? so i can be logged in but i am unsure on how to do it.

ps. i work winscp and putty on ubuntu as i cant seem to work it on windows7 as it cant detect the n9 via usb.

Thanks to hopefully someone.
