First of all, 2.10 has surely got a blockade for TN-V. Although Sony has done a better job this time, I might have my solutions to bypass this blockade.
The hypothesis that Sony tries to block TN-V will be explained now:

- TN-V uses the scratchpad memory 0x00010000 to run the kernel exploit loader. This memory is not write accessable anymore.
That would further not be a problem anymore, because we can simple use an other memory address. But this change shows you that Sony hates TN-V.

- The PSP Emulator below 2.10 used the memory range 0x8B000000-0x8C000000 (16 MB) for the flash0 files. We used to have access to this memory to dump the files / insert our own files there.
But this time, the memory will be cleared after the boot. That means that it might be more difficult to dump the flash0 files.

EDIT: Well...I managed to dump all flash files. Not as hard as I thought xD


By the way, here are the new PSP decryption keys for 2.10:

Code: Select allu8 keys210_k0[0x10] = { 0x3F, 0x67, 0x09, 0xA1, 0x47, 0x71, 0xD6, 0x9E, 0x27, 0x7C, 0x7B, 0x32, 0x67, 0x0E, 0x65, 0x8A };
{ 0x4C949CF0, keys210_k0, 0x43 }, // 2.10 psvita


Stay tuned for more informations.

Wow, thanks for the notice. Can't you try to dump flash0 by just trying to read flash0 path which is emulated?

good news :D

btw, does that mean, they remove the Blockage of SaveGame Exploits(UNO,GCP,Urbanix, etc..) then Put Blockage on Memory(Ram) where eCFW exploits was running?
