psp2etoi is a tool allows you to manage the Unique Device Identifiers (UDIs) on PlayStation Vita/TV consoles.

Usage

Please keep in mind that this tool is intended for advanced users only; a wrong configuration or program bug can lead to unrecoverable system corruption requiring a motherboard replacement.

Prerequisites

Required

The target Playstation Vita/TV console must be running firmware version between (including) 3.60 and 3.74
The console must have the taihenkaku CFW framework installed and running
The psp2etoi.vpk app package should be installed via VitaShell.

Creating a backup

Open the psp2etoi app and accept the disclaimer.
Perform a self-test.
Select "Backup the current Unique...". This will create a backup of the encrypted ConsoleID and OpenPSID.
Select "Dump the current device...". This will create a backup of the current device configuration and S/NVS.
Copy the backup files from ux0:data/psp2etoi/ and store them in multiple copies on separate storages.
The backup files include udi.bin (ConsoleID and OpenPSID in an encrypted format), output.cfg (psp2etoi configuration file), and nvs.bin (dump of the console's S/NVS).

Creating a custom configuration via psp2etoi

Place a configuration file as ux0:data/psp2etoi/input.req. This configuration will serve as a template for the custom configuration. The configuration file must have the INPUT tag set to false. Open the psp2etoi app and accept the disclaimer. Perform a self-test. Select "Create a custom...". This will parse the template and generate a matching configuration. The custom configuration can be found in ux0:data/psp2etoi/custom_input.cfg.

Installing a psp2etoi configuration

Place the input configuration file as ux0:data/psp2etoi/input.cfg.
If the configuration requires supplementary files, put them in the same directory (ux0:data/psp2etoi/).
The input configuration file must have the INPUT tag set to true.
Open the psp2etoi app and accept the disclaimer.
Perform a self-test.
Select "Apply a custom...". This will parse the configuration file and show the expected changes.
After confirming that the changes are correct, press triangle to write the new configuration.
A backup configuration file based on the input configuration will be written to backup_input.cfg.
Copy out the backup files and store them in multiple copies on separate storages. These backups can be used to revert changes made by the input.cfg.

Warning

It is extremely easy to permanently "brick" your console using this tool, so be cautious.
Make sure to understand how writing the desired configuration data impacts the device.
Always double-check the input configuration file and the app's parser output before applying changes.
Bad ConsoleID type/sub-code should be recoverable with enso_ex v5, provided you have the backed-up udi.bin.
