.51 devhook problem

ok, i have special edition-c firmware, i put the eboot on my psp, copied the "dh" "fbm" and "PSP" folders from the folder onto the root of my mem stick, and then put the "%__SCE__301_dh_fw_installer" and "%__SCE__301_dh_fw_installer" into my game folder. When i launch the new devhook installer, it just shows the psp symbol and stays white, then eventually turns off. when i turn it back on, nothings happened. What did i miss/do wrong?

What kernel setup are you using in sec? If you're using 2.71 kernel mode then you need to put the "%__SCE__301_dh_fw_installer" and "%__SCE__301_dh_fw_installer" into the game150 folder

many thanks, put it on 1.5 kernal and it's working away
