was the 8900 unlocked already? or how did you do it?
can you post your configuration file? i tried everything to unlock the 8900 using MML and cfp command lines with no luck, i always got the RTAS error and that MEP file was not found when i used the default MEP-04103-001, im beginning to think that it uses another version of the MEP but i have too many of them to like try them 1 by 1
just so i wont go offtopic, i successfully unlocked an 8320 from tmobile and successfully branded it to a blackberry engineering version
