i said that because the first time i went to 3.71 M33 there was some homebrews that wouldn't work.  so i decided to format my flash 1 and reset my settings.  when i did that i bricked with and endless BSOD error and when i shut down the psp wouldn't boot anymore.

i totally agree that the 3.71 M33 has much more features though.  well now that i made my psp brick proof with a pandora's battery and a upms memory stick i stayed on 3.71 M33.  :)
