OK so being a member over at ps3jailbreaking.com and psx-scene.com and knowing habit about downgrading here's a quick guide.
Cech2001-24xx can be downgraded.
If your on anything above 3.55 you MUST use a hardware flasher I.e proskeet or an E3.
If your own a 3.55 system all you must do is download the CFW.
ANY SITE THAT REQUIRES A SURVEY IS FAKE AND WILL BRICK YOUR PS3!
IF YOUR REQUIRED TO ENTER A PASSWORD TO UNZIP THE FILE ITS A FAKE AND WILL BRICK YOUR PS3!
If you have any other questions about jailbreaking message me or post here and I'll respond asap.
ok since you are an authority here are 2 questions i never found answers to in the ps3 scene
1) can you use a progskeet with a clip on instead of soldering? and does it have a chip clip for both nand and nor models? and are there kits or do you have to guess what components you need to get a solderless solution and buy the clip and progskeet separately
2) since e3 never released their NAND version of e3 flasher , no NAND clip, is there a way to use a NAND chip clip for a proskeet on a non solderless E3 flasher? and where do youn find a guide on how to wire up a progskeet or toehr NAND clip to a non solderless e3 NAND flasher?
because i have NEVER been able to fine even ONE decent or even halfway decent video , guide tutotrial or set of instructins on how to downgrade a ps3 with NAND solderless , on NOR with E3 flasher, do any such tutorials even exist and in english ? becaus ei have never seen any
seem like nobody gives a shit about NAND ps3 owners who are not masters of soldering
my advice would be this
1 )just get an ODE ,its not even worth it to mess with shitty china made flashers and clips, you can buy an ODE for the same price or a little more than an E3 flasher and save yourself a huge headache
2) if you buy a new used PS3 not on 3.55 or lower MAKE SURE IT IS A NOR AND NOT A NAND MODEL
3)if you have a NAND model and plan to downgrade, DONT ,sell it and buy a NOR model , there are no good guides to downgrading a NAND model
