Hi guys I need help so I'm new at updating PS3 stuff since I bought it a few years ago already jailbroken so it's a first for me to actually do stuff myself so I was trying to update my system but for more context on this I have a PS3 slim CECH-2501a currently on System software 4.82 and when booting it shows FERROX, I wanna update the system version to 4.86- FERROX Cobra but it shows me the error: The data is corrupted (8002F169) and I dunno what to do nor where to start
