3.03oe-b is a custom (unofficial) firmware that provides the features of 3.03 as well as the ability to run unofficial programs that 1.5 has. It also has a hacked official ps1 emulator to allow almost any ps1 game you have a disc image for to run on it, and even more features.
In order to install the custom firmware, you must have a firmware 1.5 psp. There are programs called downgraders that allow higher versions to be downgraded back to 1.5 (and then updated to the custom firmware if you wish).
The highest firmware that can be downgraded currently is 2.80, a psp running firmware 2.81 or above currently cannot be downgraded.
Downgraders and the custom firmware are all unofficial software, not written or approved by sony. Sony want people to update to the latest official firmware so they can only run what sony wants them to.
All people with firmware 2.81 or higher on their psps can do is to not update further, wait and hope a hacker finds a way to downgrade their firmware version.
There is no 3.03 downgrader.
2.80 is the highest firmware that can be downgraded.
Please do not try to use any of the current downgraders, and dont let someone trick you into believing there is such a downgrader as you will most likely brick (destroy) your PSP.
As soon as real downgrader for firmware 2.81 or above is released and has been confirmed working, you'll hear about it on the front page
may have ya answer;-)
