thelanzie Posted February 7, 2019 Report Share Posted February 7, 2019 I had to disconnect the battery from my jeep, and the system came up with a password requirement. I used this process, and it worked perfectly for my AVIC-x850BT! Thank you! 0|||||||0 thelanzie - usa 2019 Quote Link to post Share on other sites

Carlosoro22 Posted February 25, 2020 Report Share Posted February 25, 2020 Okay so I got everything done, took a picture and typed in what seems to be the password “EBRT” and it didn’t work. Help? Quote Link to post Share on other sites
RonS Posted February 25, 2020 Report Share Posted February 25, 2020 Remove that file (\NAND\SYSTEM\SECURITY\SECURITY.DAT) and the password will go away. Just to be safe, copy it somewhere first. Quote Link to post Share on other sites
dbt3481 Posted March 7, 2020 Report Share Posted March 7, 2020 Yeah? Care to elaborate on how to delete this file? My X850BT has the enter password keys all grey (AKA disabled) and no amount of emergency brake signal manipulation matters. It is not a hardware issue and I am an engineer with 34 years in electronic systems. I can get "testmode" up but it has limited utility. I cannot find a utility that enables me to delete or copy anything. I am trying to decide to drop the unit in a dumpster or send it in. I don't give up easily but it is not hardware and it worked up until the last battery change in my truck. I even know the password. It is not a password issue, it is a software inhibit issue... Hackmode doesn't work. Quote Link to post Share on other sites

wcpa9272 Posted March 12, 2022 Report Share Posted March 12, 2022 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 and other shipping cost. Thanks to this site the radio is now operating as designed without lock. WC Phillips Dayton, Ohio Quote Link to post Share on other sites
