You must login or register to view this content. (make sure you download the correct one.) You can now go online but you want DEX so follow Derektrotters guide here

Why are you recommending Rebug 4.21? There's a newer Rebug 4.30.2. I would recommend that instead.
So yeah dump your root key while on 3.55 and then do the following:
1- Make NOR/NAND dump (optional):
Install latest version of multiMAN (4.30.00), 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 4.30.2 from XMB:
Download Rebug 4.30.2 from Rebug's website, 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- Install Rebug Update Package 0.2:
Download Rebug_Update_Package_0.2_4.30.x.pkg from Rebug's website, verify the md5 hash, install it from Package Manager, launch it under Games and follow the on screen prompts, the screen will freeze for a while when you select Yes,
do NOT force shut down your PS3 at this stage or else you will get a nice and shiny RSOD! Just be patient and wait for it to finish what it's doing, it will reboot if needed when finished. Once the PS3 has rebooted, you can delete Rebug Update Package from your XMB as it is not needed anymore.
4- Enable QA and spoof to 4.41:
Install Rebug Toolbox from Package Manager, launch it under Games, go to Utilities and enable QA. This is to ensure easier and safer downgrading. Now go to Selector and change System Mode to
Rebug, this will spoof to 4.41 to prevent accidental updates and allow PSN access.
Then follow the CEX2DEX guide above starting from the "Dumping NOR/NAND" step and replacing every Rebug 4.21 with Rebug 4.30 (the steps are the same for Rebug 4.30)
