(adsbygoogle = window.adsbygoogle || []).push({}); Alright guys. I have two PS3 :
1) Slim 120GB with CFW Rebug D-REX 4.75.3
2) Fat 80 GB with OFW 4.76

I'd like to backup the data of my internal CFW HDD to a external HDD, and then import this backed up data to the internal HDD of my PS3 OFW. First thing I wanna know : is this possible?

And if yes, second : I want to delete all possible traces of CFW files. So, before backup my data, in dev_hdd0, I should delete :
.prx/sprx files ( also in dev_hdd0/tmp )
.txt files that loads plugins
GAMES, GAMEZ, PS3ISO, PS2ISO, PKG, etc folders of multiMAN
packages folder ( the Custom Install Package Files of Rebug )
Homebrews in dev_hdd0/game

Then of course, I'll delete all users and make a new one. Note that I don't wanna mod in OFW, so there will be no Mod Menu in game patches.
Is there something else I should delete that adds in dev_hdd0 because of CFW? Let me know.

You would like to make your OFW jailbroken using your CFW HDD? That is not possible, unfortunately.

No no I'm not trying to make my PS3 OFW Jailbroken. I'd like to know if it's possible to just import the data of the HDD PS3 CFW to the OFW one

I do not think so. What is on the HDD that you would like to import to the OFW?

Wanted to test if it was possible to run games. I mean, digital games activated via fixed EDAT, and not via rap activation.
So, if the game would pop up in PS3 OFW, when you boot it, it won't do the license verification ( rif file ) and it will directly boot cause of edat fixed.

I think I'll do a test though

You can data transfer, but it will wipe all data on the OFW.

Alright thanks, going to try it today

Make sure your CFW is on CEX, you cant data transfer DEX -> CEX

Oh! Wait,
I have to transfer from CFW to OFW, so my CFW must be CEX? ( cause I'm on DEX )

Edit : Also, can you tell me if I should delete these folders too?

game_debug
xmlhost ( contains a folder called game_plugin, and there are these files, background.gif, fb.xml, mobile.html, mygames.droid, mygames.xml )
I opened for example the file mygames.xml and it contains strings referring to webMAN..

Yes you need to go from cex to cex, and only if you are planning top go online should you delete those.
