PlayStation 4 DevKit Activation Guide & PS4 DevKit NEO Downgrading with DevKit PUP

A few days ago we reported on PS4 DevKit / TestKit Settings for developers, and since the PS4 Retail / Debug Game Transfusion Guide PlayStation 4 developer ZiL0G80 spotted some code of interest in the TMServer-3_50_0_55.msi file of the PS4 *** Leak that (similar to PS Vita) may allow the activation of PS4 DevKits by unlicensed developers through 2020 following the PS4 DevKit Activation Tutorial by Jerry Yin below.

Here are the related Tweets:

From TMServer-3_50_0_55.msi thanks to @oneman123 on Pastebin via Hydrogen:

                try
                {
                    using (CtrlCHandler handler = CtrlCHandler.StandardCtrlCHandler(tgt))

                        tgt23.UpdateCPFirmware(path);
                        success = ph.Success || success;
                    }
                }
                catch (COMException e)
                {
                    ErrorHelper.PrintError(tm, e);
                }

            return success;
        }
    }

Here is the PS4 DevKit Activation Guide / Tutorial, to quote from Jerry Yin:

Before you do this, remember to disconnect from the Internet, and also remember to set the computer time to 2009.

1. Disconnect all the cable
2. Tear the Dev kit apart
3. Remove the CP board
4. Remove the battery
5. Connect CP board to the mother board and leave the battery away
6. Connect the cable (CP first, then power), and power it on
7. Set time to 2009.1.1 00:00

You will get backup battery error message. Open neighborhood and connect the dev kit, then refresh the status, at last reboot through neighborhood, after reboot, you will see the clock (not date) was change.

8. Disconnect the usb cable and keep the power cable connect
9. Put the battery back into the dev kit.
10. Connect the usb cable and power it on, the battery error message should gone. If not, disconnect all the cable and plug it again.
11. Once you discover the battery error message was gone, open neighborhood and connect to the dev kit and then refresh, wait serval minutes then reboot
12. After reboot, you will get an activated dev kit

A big THANKS to @HydrogenNGU for sharing the news in the PSXHAX Shoutbox and to @SilicaAndPina on Twitter!

I think the only way to reactivate the PS Vita testing kit is only a valid AFV file

 

[PSXHAX]

Not sure if there is a way to mod this for the Vita, but here is the leaked PS4 AFV file:

I think that I'd need a person that has ps vita dev kit activated with 3.60 firmware and he should dump the file in this path: ur0/temp/activation/vita_activation.afv

Hi everyone I need help because I bought a PS4 pro DUH-T7000AA test kit I have the message in red Expired but impossible to activate. I was told that there was a specific payload for ps4 pro to activate it.

I really need help as i am trying to put al-azif browser but i am told it is not working as it only works for ps4 DUH-T1000AA. Is there there a way to enable it please? thank you very much.

You need the afv file, you should probably search & research into this beforehand. Please don't mod online either.
