(adsbygoogle = window.adsbygoogle || []).push({}); I'm trying to downgrade to 3.55 to change my MAC address, but I keep getting errors like "the system update is not compatible for the system" or "800" errors.

I'm currently on Rebug 4.78 DEX.

I've tried a number of downgraders, even the ones on the Rebug website.

Can someone please help me?

Sen Enabler could be the issue, launch it, go to SEN/PSN Options, then disable SEN access. Hard reboot. Re-launch Sen Enabler, go back to SEN/PSN Options, and Restore Default Spoof. After that, yes go ahead and install 4.78 REX. If no luck, once again try a downgrader since you restored system files using SEN. I recommend Rebug Downgrader, which can be found here: You must login or register to view this content.

I get an error on both. "The data is corrupted (80029CCA)"

It's impossible..

Maybe something you are using is damaged, whether that be the usb port of your ps3, the hdd of the ps3, the flashmemory of the ps3(99.9% unlikely), the usb flash drive, or your computer and its ability to copy files.

Try another known working usb flash drive (formatted to fat32)


To install an update to a cfw ps3:
1. Download the cfw you want to install
2. Rename the file to "PS3UPDAT.PUP" (no quotes)
3. On the root of a fat32 formatted usb flash drive, create a folder named "PS3"
4. Inside the "PS3" folder, create a folder named "UPDATE"
5. Inside the "PS3" folder, place your "PS3UPDAT.PUP"

folder structure should be:
fat32formattedflashdriveroot/PS3/UPDATE/PS3UPDAT.PUP

6. Install the usb flash drive into the rightmost usb port of the ps3
7. Boot ps3 into recovery (alt. go to XMB, top of second column from the left)
8. Select option "Update System" (select from usb device)
9. Follow prompt and install



If it is still not letting you install updates, and you don't know the software or setting that has caused you to lock up, really you're only option is to reformat or try another known working hdd in hopes that it will reset whatever has caused this.

Before reformatting, go to rebug toolbox/ system information and look at your target type. You will install a (CEX) or (DEX) downgrader based off of that, after reformatting.

To reformat your hdd:
1. Boot ps3 into recovery mode
2. Select option "restore ps3 system"
this will wipe everything, accounts, games, saves, etc
when it is finished you will be brought to a black screen, asking for your last syscall (last cfw installed)
3. Install one of the downgraders below (based on target type you gathered before)


If you install another known working hdd:
1. Install the new hdd into the ps3
2. Boot ps3 into recovery or just turn it on..
3. select option "restore ps3 system" or follow prompt..
This will format the new hdd to the ps3
when it is finished you will be brought to a black screen asking for your last syscall
4. Install one of the downgraders below

Keep trying.

GL! let us know how it goes.

OK Thank you all so much your help! Will try these. Can anyone link me with a HDD that is compatible for PS3?

Didn't see you replied with an error, you need to quote me back! Go ahead and try the other solutions Dro has provided before changing HDD's, but you can google "PS3 HDD", very easy to find and cheap.

Ok guys it worked, but unfortunately I had to restore the system, but on the flip side I changed my MAC and my CID. But I'm still banned on GTA, so this leaves me thinking that the ban isn't perm as it says it is until the 30th of May. What do you guys think?

Yeah those bans are what they call "First Strike" bans so no it's not permanent.

Glad to hear! So it was the HDD? And they don't really do Mac bans anymore. Are you sure it's not an account ban if you're other CID still says banned?

Idk, I just restored the system in safe mode then went through the update process. And it's not account ban because every account I sign into it says the same thing..."You have been banned from GTA Online until 2016/05/30". At first I was frustrated because I thought it was a perm ban until I realized that I've changed mac & cid so I did research & found that the ban isn't forever.
