Becaues it detects it as the same firmware, you will have to upgrade it to 3.91 m33 or higher instead of 3.90.

people, if you dont know dont answer. all youre going to do is confuse this person. the only official firmware that you can directly update to a custom firmware is 1.50. the only way to install ANY custom firmware on 3.90 is with the pandora battery and magic memory stick.
