3.71's 1.50 kernal addon question

[Vandel212]

I tried to update my psp (it has 3.71 M33-2 fw on it) with the 1.50 kernal addon. When I tired to do it, it gave me the error: 150PBP is incorrect or inexistant. What do I have to d to fix this? Thanks.

Do you have the 1.50 update located on the root of the memory stick labeled 150.PBP? Otherwise the addon won't install.

Try downloading again (download a few from different places) and see if the MD5 is the same as the following.

BTW, update your 3.71M33 to Update 4. There's a few bug fixes (which was in update three, but for is more complete)
