Hello again
Today i played a bit more with my PSP and i at least i know that my PSP290 is working.
I downloaded the PSP290TEST, took the prx's from 3.40OE-A und changed kernel to 3.40. After few seconds it found 3 satelites so basically no problem with reception and/or my PSP.
Then i tried to start MapThis with 3.40 kernel and it crashes with 'game could not be started' and some hexcode.
I changed the kernel to 1.50, started MapThis once again but the GPS State won't change (and yes i pressed the square button).
