All these answers come from a very reliable PS3 Scener (@Mathieulh)
Q: Can you dump the 3K and 4k NOR with an E3 FLASHER?
A:Yes, but make sure its a NOR as some 4ks have a eMMC instead
Q: Can you Jailbreak PS3's with the new Metldr2?
A: Sort of, on FW 4.30 YOU CAN Webkit payload (or fself on dex) + rsx related syscall bug to gain lv2 execution + trick to bypass lv2 hash check. but it needs applied EVERY Boot
Q: Could you change the Syscon FW Hash to downgrade?
A: You'd need hardware access to the syscon eeprom. I would rather get an exploitable console.
Q: Is it possible to crack the Metdlr2?
A: No, you can "dump" it using unconventional ways, but you can't actually get code execution on it.
