has examined PSP firmware v3.80 changes, and here are the results:
They now know that with Pandora, we can always access the flash, so they've focused on locking down the PSAR and changing the format of the files/flash. Just more tactics to slow down decryption, but it won't work.
They have only changed the keys of the tables of filenames. The prx's keys are the same than in 3.7X.
However, there is a little surprise in a form of new compression algorithm called KL4E, this time sysmem and loadcore are also compressed. Plus... again new nids.
So it would seem as if the newly-released PSP firmware v3.80 has already been dumped and decrypted. Only time will tell is Alex will release an update to M33 CFW or make users wait longer.
3.80 module list and decryption info below:
Only a example, the offsets for show another version in 3.71 are:
In 3.80 are:
And in 3.80 the nid scePaf_82D1FFD2 is scePaf_28A83D9F now.
