If you see “1302” or “900” errors without wanting risky hardware mods:
If you updated directly from 9.00 to 13.02, this might work. If you updated from 12.50 to 13.02, you could only go back to 12.50. 2. The "Hard Swap" (Board Replacement) The Concept: ps4 downgrade 1302 to 900 top
Downgrading a PS4 from firmware directly to is currently impossible through software alone. The system is designed to prevent downgrading to stop users from exploiting older firmware versions. If you see “1302” or “900” errors without
Firmware 9.00 is highly desirable in the hacking community because it was the last major firmware that had a reliable, user-friendly exploit (the pOOBs4 kernel exploit). user-friendly exploit (the pOOBs4 kernel exploit).
