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.

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.

Warning

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.
