NO DO NOT INSTALL 5.50 GEN OR 5.00 M33 ON A 3000 YOU WILL BRICK

Get 6.20 TN-E or 6.20 PRO

yeah. Josh is right. 3000s have this motherboard that detect certain cfws and just shut itself down when it finds cfw. until new and improve cfw came. Now you gotta use HEN for psp-3000s. get 6.20 TN-E or 6.20 PRO like what he said. (Get PRO because from what I heard it's better)

6.20 is permanent.

Another thing... The motherboard does not "detect" custom firmware by an stretch of the imagination. It is something to do with the boot process of the PSP 3000, and any 088v3+ motherboard. Dark_AleX explained it like so:

Dark Alex wrote:: When the PSP boots, the boot code (aka pre-ipl or ipl loader) loads the ipl from either the nand or memory stick. The IPL is splitted into pieces of 0×1000 bytes.

First 0xA0 bytes of each block is a header for the kirk hardware command 1. It contains keys, the size of the cipher data, and two hashes, one for part the header itself, and another one for the body. The 0xF60 remaining bytes are the ciphered body, which will decrypt to 0xF60 plain bytes… if the hashes, which are checked by kirk hardware itself, are OK. (Note: ciphered body can actually be less than 0xF60, in this case, remaining bytes are ignored… before TA88v3)

What has Sony added to fix this?

The answer can be found in 4.00+ slim ipl’s. They decreased the size of the ciphered body to 0xF40 to leave 0×20 bytes at the end of each block (at offset 0xFE0). In newest pre-ipl’s, these 0×20 bytes have a meaning.

This protection also destroys any possibility of downgrading below 4.00, as these new cpu’s won’t be able to boot previous firmwares ipl’s.

Summary: basically, all security of newest psp cpu’s rely on the secrecy of the calculation of those 0×20 bytes. If pre-ipl were dumped somehow, the security would go down TOTALLY.

Has absolutely NOTHING to do with detection. BTW, m33 and 5.50 GEN will indeed brick a PSP 3000.

6.20 Pro B4 & Pro B5 can be permanent a 3000, sworn posted a tutorial on how to do it

In my opinion, 6.20 PRO-B5 Permanent Patch is the best CFW for a 3000 right now...very compatible, stable, reliable, and much more user friendly....i havent had a problem with it yet, but to each his own...just thought id throw my 2 cents in.

when sworn told me to get 6.20 pro b4 i had a few minor bugs eg, some prx's not working

6.20 pro b5 came out 2 days later and all my minor bugs are fixed

also i think 6.20 pro b5 is better than 6.35 pro b5 because 6.35 was unstable and caused a few bricks... but both of these cfw can have perm patch
