i read some previous posts on people with ta82 not being able to update to custom firmware because, i think, all keys must be original, i wanted to take my 3.40oe and update to 3.50 because yesterday i bought 2 copies of lumines. i just want to try it out. it gives me error trying to get new update.
If i go back to 1.5 original then to 2.00 original would it let me go to 3.50 original without the error? or do i need a clean key 5 to replace first?
