(adsbygoogle = window.adsbygoogle || []).push({}); Okay so I've seen multiple threads on here and other forums be closed because people are asking what PS3 models can and can't be jailbroken. I'm going to make a list including pictures of which models can be jailbroken and which cannot. Remember, no matter what model you have, you need to be on 3.55 OFW or lower. It is necessary to be on 3.55 or lower because if you are on firmware above 3.55, there is no possible way to jailbreak unless you downgrade. If you're not on 3.55 OFW or lower, you must downgrade with special hardware. If you see the # symbol, that means I'm covering for a number. If you see the * symbol, then it means I'm covering for a letter.

If you have no idea of what your PS3 model is, check of the back of your PS3 and it should be beside the serial number starting with "CECH"

Special thanks to the person who downgraded my PS3 for this info!

No such thing as 2003b you mean 2001a/b or 2501 a/b basically just look at the manufacturer date and make sure it's before 2011 so anytime in 2009 or 2010 is fine for all slims , if it's a fat made after june 2007 for nor chip before thay is nand
