This tool allows you to backup or edit the Unique Device Identifiers - ConsoleID and OpenPSID.

The utility is also capable of dumping or flashing the syscon S/NVS that contains configuration data such as QA flags, management flags, boot flags and much more.

Note: This tool is intended for advanced users only; a wrong configuration or program bug can lead to unrecoverable system corruption requiring a motherboard replacement.

User guide

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. After accepting the disclaimer it will perform a selftest.
• Select "Backup the current Unique...". It will create a backup of encrypted ConsoleID and OpenPSID.
• Select "Dump the current device...". It will create a backup of the current device configuration and S/NVS.
• Copy out the backup files from ux0:data/psp2etoi/. Store them in multiple copies on separate storages.
  • udi.bin is the ConsoleID and OpenPSID in an encrypted format that can be directly written to idstorage.
  • output.cfg is a psp2etoi configuration file containing all data that psp2etoi can modify.
  • nvs.bin is a dump of the console's S/NVS.

Writing a custom configuration

• Refer to the configuration manual.

Creating a custom configuration via psp2etoi

• Clean the ux0:data/psp2etoi/ directory.
• Place a configuration file as ux0:data/psp2etoi/input.req.
  • This configuration will serve as a "template" for the custom configuration.
  • The configuration must have the INPUT tag set to false.
• Open the "psp2etoi" app. After accepting the disclaimer it will perform a selftest.
• Select "Create a custom...". It 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

• Clean the ux0:data/psp2etoi/ directory.
• Place the input configuration file as ux0:data/psp2etoi/input.cfg.
  • If the configuration requires supplementary files put them there too.
  • The input configuration must have the INPUT tag set to true.
• Open the "psp2etoi" app. After accepting the disclaimer it will perform a selftest.
• Select "Apply a custom...". It will parse the configuration file and show 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.
• You should copy out the backup_ files and store them in multiple copies on separate storages.
  • They can be used to revert changes made by the input.cfg.

Notes

• It is extremely easy to permanently "brick" your console using this tool, so be cautious.
• You should only use this tool having understood 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.
