I did it :) its easy to, i cannot belive i was having trouble lol, you use SETool2 Lite, you select your phone model and put the Enable AMR Script into "Misc" (AMR Script can be found in download section) and push "Write Script" :) i was pushing write GDSF which was leaving my phone dead lol.

Note: before enabling AMR on your phone, its a good idea to backup the GDSF first by selecting your phone model and clicking "Read GDSF" just in case something goes wrong :p
