PSP: Dark_AleX releases 3.71 M33-2 & 1.50 Kernel Addon v2

[michalt441]

I installed 3.71 M33-4

But when I install 1.50 kernel addon v2
(I didn't install 1.50 kernel original before)

I press X and it says
Incorrect or inexistant 150.PBP at root.

And then it turns off.

Please help me fast!

Download the 1.50 firmware update, unpack it to the top level of your memory stick, the root, where the PSP folder is, and rename it to 150.PBP, then start the kernel addon program.
