Downgrade from V2.0 to V1.5 Network Settings

Hi there,

I just successfully downgraded my PSP firmware from V2.0 to V1.5. However while setting up my network settings (Infrastructure mode), it seems like it cannot support WPA-PSK (TKIP) mode?

Came across a few articles that mentioned V1.5 does not support WPA, not until V2.0, is that true?

If it is, is there any hack outthere that could allow V1.5 to work with WPA encryption?

Any help would be much appreciated.

Thanks.

The answer to that would be to wait until someone has found an exploit for v2.0.
