I have a similar question and didn't want to start a new thread.... I have a PS3 Slim with Kmeaw CFW 3.55 haven't used it for over a year my controller doesn't work not sure what that's about.
My questions is pretty straight forward I wanted to know If I can do a full reformat of my Playstation and if that will just go back to factory default system or do I need the OFW (Version 3.55 then update to 4.41 or just OFW 4.41) to complete the reformat.
All I'm trying to do is Play CoD online and not worry about the CFW anymore I've had my fun with all the backups and now i just want to play online. I've read that I might need a program to erase my update logs so PSN doesn't see that is was hacked or does the full reformat do that?
There's little to no reason to stay on 3.55 CFW these days, just install Rebug 4.41.2 from XMB on top of your kmeaw by following the guide below:
1- Make NOR/NAND dump (optional):
Install latest version of multiMAN (4.41.2), plug in a FAT32 formatted USB flash drive into the right USB port, launch multiMAN under Games and go to mmOS > Press [O] on any file > Open in HEX viewer > Press [SELECT] > Press [START] > Export GameOS LV2: Select No > Export HV LV1: Select No > Export FLASH: Select Yes
2- Install Rebug 4.41.2 from XMB:
Download Rebug 4.41.2, verify the md5 hash, rename the PUP to PS3UPDAT.PUP, put it on your FAT32 formatted flash drive in PS3\UPDATE, go to System Update and Update via Storage Media. Make sure there's NO original game disk in the drive and that you DON'T Update via Internet or else you would risk installing OFW higher than 3.55!
3- Enable QA:
Install Rebug Toolbox from Package Manager, launch it under Games, go to Utilities and enable QA. This is to ensure easier and safer downgrading.
Make sure you use the latest version of mM (4.40.00) because it's the only Backup Manager compatible with 4.41 CFW atm.
So the above post is answering chrisax305 question. So should I just reformat the HDD and install OFW to play CoD online or does the PS3 install the OFW automatically once the HDD is Fully reformatted?
Does this get rid of the CFW and revert it back to a factory default PS3?
