PS3Xploit Tools v2.0 to Install PS3 CFW on 4.82 OFW Consoles | PSXHAX - PSXHACKS
I purchased a PS3 backward compatible from ebay for a good price and I'm impressed how clean it is. However... It's still on firmware 2.50. Should I update the firmware? : r/PS3
PSA: Don't upgrade your PS3 to 4.83 if you want to use CFW : r/emulation
