i give me the anser myself:
i had unpached my key t o run 3.52 after the kernel 1.5 won't work.
So i have restored my nand with with my M33 backup without the key, so my PSP had the key to run 3.52, but the M33 was installed.
And M33 start with 1.5kernel, because the key was not pached for that the PSP bricks.
