The team Rebug us a utility to easily enable and disable the QA Flag without a special custom firmware.
Toggle QA QA enables and disables the Token and Flag on any PS3 custom firmware 3.41 or 3.55 that the "lv1 mmap" and "peek and poke lv2" (most have customs). When you run the application, it first detects if the PS3 is 3.41 or 3.55. Then it checks the patch you've already Lv1 and install those missing in the hypervisor. When finished, Toggle QA checks the status of the flag and modify accordingly. Once all done, the patches LV1 will be deleted. Instructions: 1: Install toggle_qa.pkg 2: Run from the XMB Toggle QA 3: PS3 beeps and return to XMB. (If you do not hear a beep, it did not work, reboot and try again) As each authoring software in flash memory use is risky. Homepage: http://rebug.me
