How to check if a DevKit's Firmware is Internal/External

Activate and try run a game cartridge. If there is an error it is most likely internal. To confirm it needs to be dumped and the modules checked.

How to check if a DevKit has been activated before & when

via Neighborhood

Download psp2ctrl.exe
Running psp2ctrl.exe get-setting kernel:/bootparam will return something like 45 03 C7 63 01 13 04 00 45 03 C7 63 00 00 00 00 01 00 00 80 00 00 00 01 00 00 04 00 18 00 00 38 <binary>:System.Byte[] where "45 03 C7 63" is the date (here 17/01/2023)

How to check if there is a QAF token installed

In any case dumping NVS is the savest way to tell for sure if and which kind of token is installed!

CEX (Retails)

Dumping NVS or using Apps to check and display the token name. (eg: PSVident or QAFUtility [PCSI90043])

DEX (TestKits)

When the Kit is activated for a very long time there most likely is an active QA Token installed.

TOOL (DevKits)

When the Kit is activated for a very long time there most likely is an active QA Token installed. For DevKits you can often tell from the Console Output alone as it will have additional debug output. It is however possible that there is an inactive token still installed while the firmware was reverted to external for example. In that case only dumping NVS can tell.

What kind of QAF Tokens are there and what do they do

Name	Flags	Notes
QAF_QATEAM_E	01 00 00 00 00 00 0D 04 64 00 00 00 04 00 00 03	for "QualityAssurance Team" units (early)
QAF_QATEAM_MINI_E	01 00 00 00 00 00 0D 04 64 00 00 00 04 00 00 03	for "QualityAssurance Team" units
QAF_QATEAM_FULL_E	11 00 00 00 00 00 0F 04 64 00 00 00 04 00 00 03	for "QualityAssurance Team" units
QAF_SYS_DEV_I	33 00 00 00 00 00 07 05 73 01 00 01 06 03 03 01	for DevKits used for "System Development"
QAF_MGVIDEO_DEV_I	33 00 00 00 00 00 07 05 73 01 00 11 06 02 03 01	for DevKits used for "MagicGate Video Development"
QAF_MGVIDEO_ADV_I	33 00 00 00 00 00 07 05 73 01 00 11 06 03 03 01	for DevKits used for "MagicGate Video Development"

The "_E" / or "_I" suffix indicates the Firmware the token is for. (External / Internal)

How to re-activate a DevKit

The CP Battery cannot be empty!

via PC

via modded psp2ctrl.exe psp2ctrl.exe get-setting kernel:/bootparam will return something 45 03 C7 63 01 13 04 00 45 03 C7 63 00 00 00 00 01 00 00 80 00 00 00 01 00 00 04 00 18 00 00 38 <binary>:System.Byte[] where "45 03 C7 63" is the date that you need to replace with current time. Then write back via psp2ctrl.exe set-setting binary kernel:/bootparam "XX XX XX XX XX XX .."

by BatteryTrick

remove the Battery for a couple seconds and set the earliest possible date. (You can re-de-activate via setting time via Internet)

How to dump a DevKit

with Activation via Neighborhood

0) Re-Activate
1) rename "devdump_xxxxxx.skprx" to "bootstrap.skprx" and put into local file serving directory (host0)
2) enable devmode (via for example psp2ctrl set-setting integer bootparam:/development_mode 1)
3) run "ngs_exploit_XXX.self"

NGS Exploit files: https://www.mediafire.com/folder/7h2n6rqu5rqks/NGS
Devdumpers: https://github.com/SKGleba/VitaTools/tree/main/devdumper/build

without activation

use Henkaku / Henlo

How to downgrade a PDEL below 1.692

Install a Henkaku/Henlo hackable firmware and then use modoru v1.0 (since it provides its own spkg keys when decryption fails)
