I was under the impression, and I could definitely be wrong on this, that you could flash to a lower region (005 to 001) IF, you are flashing to a newer PR, such as 1.1, to 1.2 I would think that if it's simply a numerical value, that being that the first number is 30, then that would make it a higher number, regardless of the ending of the string (005 to 001) However, you can't flash to a "lower" PR. So you can't flash from 1.1 (005) to 1.1 (001), but you can from 1.1 (005) to 1.2 (001) I could be completely wrong on this and much smarter people than me are welcome to correct me, but I figured this is how it worked.
