So, I've been running 4.21 Rex for a while now, love the firmware.
Unfortunately, my BD drive got unmarried somewhere along the way from 3.55 to 4.21. I've been trying to figure out how to get my ps3 to DOWNGRADE to 3.55 again. I believe i successfully QA toggled on 3.55, but 4.21 can't show me that. (recovery asks for a firmware 2.50 or later)
Unfortunately, I can't update to 4.30 rebug, or downgrade to 3.55 OFW. My ps3 states that any firmware is corrupt. I'm currently getting error: 8002f828 (though it seems to change depending on settings/update files). Being in recovery mode doesn't matter either.
Is there anything I can do to downgrade my ps3?
