Honestly, yes because you wouldn't have to look for eboot/update patches anymore and it's really easy. This is what you have to do:
1- Enable QA:
1: Download and install Rebug's toggle_qa.pkg
2: Run Toggle QA from XMB
3: PS3 will beep 3 times and return to XMB. (If you do not hear the beeps it has not worked)
NOTE: Every now and then it will hang on the lv1 patching stage. If it has not beeped and returned to the XMB after about 30 secs you will need to reboot and try again.
Check that QA has been enabled by selecting Network Settings (stay ON Network Settings and DON'T GO INTO Network Settings) then press L1 + L2 + L3 (press left stick) + R1 + R2 + dpad_down all at the same time, you should see Edy Viewer, Debug Settings, and Install Package Files if QA has been enabled.
2- Make NOR/NAND dump (optional):
Install latest version of multiMAN, plug in a FAT32 formatted USB flash drive into the right USB port, go to mmOS->Select any file->Open in HEX viewer->[SELECT]->[START]->DUMP LV2(NO)->DUMP LV1(NO)->DUMP FLASH(YES)
3- Install Rebug 4.30.1 from XMB:
Download Rebug 4.30.1 from Rebug's website, rename the PUP to PS3UPDAT.PUP and put it on your FAT32 formatted flash drive in PS3\UPDATE and go to System Update and update from storage device (or something like that). Make sure there's no original game disk in the drive and that you don't update from the Internet or else you would install OFW!
You will have to restore your original unpatched eboots and/or install the latest original unpatched updates for games that you had patched for 3.55.
