3/15/2022 Placing Hackmode.Key & Testmode.Key allowed AVIC-X850BT to boot with File Maintenance Menu. Then using Volume up and down buttons on the radio face allowed navigation to NAND/System/Security menus, then reading out Security.Dat onto the screen revealed the password and reminder key. Removing SD card boots radio which then was unlocked with the recorded password. Worked as described above. Pioneer wanted me to uninstaall radio, ship to them $18.00, the shop would unlock for a falt fee of $50, then free ship back to me. I saved the $68.00 plus potential damages
