I downgraded my BL to 3.9 as described in the HW unlock guide. For whatever reason I could not use the BB downgrader. So I tried restoring by iTunes without any success. I got the "repair" messages, I tried like someone mentioned by restoring to 1.0.2 and iBrickr and I could even activate it (1.0.2) but I was not able to get the BB back. bbupdater did not work. Now I wonder if I could restore 1.1.3 without a risk? I am a bit lost...
