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

Recommended

• The target Playstation Vita/TV console should be running release firmware version 3.65 of type CEX/DEX/TOOL/CFT
• As a form of recovery the console should have enso_ex v5.0 installed and running

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.
