[Q] need some advice before i root my Xperia U - Sony Xperia P, U, Sola, Go

hello. im a user of Xperia u. st25i ics 4.0.4 build number 6.1.1.B.1.10. i just want to ask the experts before i root my phone.
1)what is the advisable method for me as a noob user?(easiest and safest way of rooting)
2)what are the disadvantages if i root? i've read somewhere that the led bar will function incorrectly is that true?
3)if the rooting process has been stopped, will it ruin the phone?
i have some more question but i cant remember it for now, maybe because im so nervous about rooting. thank you very much in advance.

1) if you want to root .10 Fw you can do it easily by using binary method.... But why you don't flash .54???
2) no disadvantage as such until you know what you are doin..... And I don't think led has anything to do with rooting until you are on stock Rom
3) no it won't do any serious damage... You can repair easily....

bootloader has nothing to do with stock ROM installation.....
for your region it may not be available but you can download it and install using flashtool.......
