Hacking Question About PS3

[Mylink5]

Hello! I have a used PS3 so I don't know if it has been in OFW 3.55. But as I have guessed I can learn from the model number. If it HAS been, is it possible to just install the 3.55 or do I still need a downgrader chip? (Sorry for the overused question, just couldn't find an answer that fits.)

If the firmware is newer than 3.55 you need a hardware flasher.

To know your console's oldest firmware, there's an application you can run.

it will display the lowest firmware version you can downgrade to. (you can't downgrade bellow the firmware installed when you bought it)
