iPhone 3G BB 06.15 FW 3.1.3
ok guys here is my issue:
yesterday a friend of mine came with an iPhone 3g stuck in recovery mode he did not know which FW or BB version it had, he just said that by mistake he restore it on iTunes and that was the end it got stuck on recover mode, i tried restoring stock FW from 4.0 all the way to 4.2.1 with tiny-umbrella open to see if he had shsh saved with no luck finally i restored to 3.1.3 and the phone finally booted up thats when i noticed the phone is on BB 06.15.
Now i know that once you update to the ipad bb there is no more stuck fw restore posibility, it all has to be custom FW, however i'm a Windows user and i cannot use Pwnage tool, i got online a cust 4.2.1 FW but i've being trying to restore to that FW without luck, itunes wont let me, anyone has any ideas how can i solve this without a mac?
Thanks in advance.
