qa flag ps3 then use rebug 999 downgrader it will put your ps3 on 3.55.4 rex

do i install the package qa flag or just go to the toolbox and enable it?

ya you can go tool box and enable it

when i try to update to the 999 downgrader i get an error saying its corrupted?

Quote people so they get the reply. Try go into recovery mode and use 999 Downgrader.

No need to downgrade first, just install Rebug 4.41.2 on top of SGK 4.41 from XMB by following the guide below:

1- Dump your NOR/NAND Flash (optional):
Install latest version of You must login or register to view this content., 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 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- Enable QA:
Go to Package Manager > Install Package Files > PS3 Hard Disk and install Rebug Toolbox. Launch it under Games, go to Utilities and change Toggle QA Flag to Enabled. This is to ensure easier and safer downgrading.
