no it's not that big

it just allow us to look into che ps3 flash memory but could lead to very important things

i'm not sure if you can downgrade the ps4 using your OLD flash dump, this would surely be an important step forward!

Very interesting work!

Do we still need to unsold the memory?

EDIT: slb2.exe is no longer available T.T
