i dont think its the cust pack. cause if it was the cust apck then the error should say something like "please contact service provider"?...isnt it? i maybe wrong so please correct me if i am. though i dod recomend that you do a full flash again just to make sure you havent messed up a step by accident (flash the main, fs and cust pack). dont through away your old GDFS back up...you may need to use that if it is a GDFS damaged (which i think it is). good luck
oh! and the africa thingy...i think it because europe2 is that region. so thats why.
