Modoru 2.0 - Downgrade PS Vita Firmware (3.73)

Modoru 2.0 by SKGleba is an unofficial update of TheFlow’s original Modoru homebrew application for downgrading firmware versions on PS Vita. Modoru 2.0 brings 3.71+ support which was sorely needed as the original application caused PS Vita’s on the latest firmware versions to softbrick.

3.60 is still the golden firmware and users are strongly advised to downgrade to this version for the greatest compatibility with homebrew applications and plugins. Firmware 3.60 also grants access to the persistent custom firmware hack Ensō, meaning you will not need to re-run the HENkaku exploit upon every reboot.

Required Downloads:

Requirements

PlayStation Vita with Custom Firmware

The Modoru homebrew app requires an active custom firmware exploit running on your PS Vita
If you are on 3.65-3.68, install the h-encore exploit
If you are on firmware 3.69-3.73, install h-encore²

PS Vita devices on firmware 3.71+ should NEVER use the original version of Modoru by TheOfficialFlow to downgrade, ONLY use Modoru 2.0 by SKGleba to downgrade from firmware 3.71 / 3.73.

PS Vita 1000 (Fat) Models require an official Sony Memory Card to install homebrew

PS Vita Firmware File (PSP2UPDAT.PUP) [Full List]

Modoru requires the chosen firmware’s update file to downgrade to your chosen firmware
The update file must be named PSP2UPDAT.PUP
Downgrade to 3.60 for the HENkaku exploit (recommended)
Downgrade to 3.65 for the h-encore exploit

You can downgrade to any firmware with Modoru 2.0, however Ensō (permanent CFW) is only compatible with 3.60 and 3.65.

You will not be able to downgrade to lower than your PS Vita’s factory firmware, so newer consoles may not be able to downgrade to 3.60.

Wi-Fi or USB Connection

You will need a Wi-Fi or USB connection to transfer the install files via FTP or USB with VitaShell

SD2Vita Adapter (Recommended)

Greatly expand your storage options with the MicroSD to PSVita (SD2Vita) adapter
Convert the PS Vita game slot into a MicroSD slot
128GB or larger MicroSD recommeded for storing games
Follow this guide on setting up the SD2Vita

Installing Modoru 2.0

Modoru 2.0 requires you to manually disable all plugins before installing, so you will not be able to use your SD2Vita or Ensō temporarily while you downgrade.

FTP mode is required to access ur0: (internal memory), you may connect via USB mode when you are transferring to the ux0: directory (memory card).

On your PS Vita, launch VitaShell and Press [Select] to enter FTP mode
Enter the address displayed on the PS Vita in your PC file browser e.g. ftp://xxx.xxx.x.x:1337
On your PC file browser, go to ux0: and create a folder called vpk if it doesn’t already exist
Copy modoru.vpk to the ux0:/vpk/ folder
Press [Circle] to close FTP/USB mode
In VitaShell, go to ux0: -> /vpk/ then highlight modoru.vpk
Press [Cross] to install it and confirm the extended permissions prompt
Press [Select] to enter FTP/USB mode again
On your PC file browser, copy your PSP2UPDAT.PUP update file to ux0:/app/MODORU000/ on your PS Vita
Go to ur0: and rename the /tai/ folder to /taibackup/
Go to ux0: and rename the /tai/ folder to /taibackup2/ if it exists
This will disable all of your plugins.
Press [Circle] on your PS Vita to close FTP/USB mode
Exit VitaShell and reboot your PS Vita
Launch h-encore² and select [Install HENkaku] then [Exit] once it is installed
When your PS Vita reloads, open [Settings] -> [HENkaku Settings] -> check [Enable Unsafe Homebrew] then close Settings

You’ve now disabled your plugins and enabled homebrew via HENkaku, you can now run the Modoru 2.0 app to downgrade to your desired firmware version.

Downgrade PS Vita Firmware

Launch the new Modoru 2.0 bubble in your LiveArea
Press [Cross] to confirm and wait 20 seconds
DO NOT attempt to downgrade using the original Modoru release by TheFlow, ensure you are using the unofficial update by SKGleba by checking for [mod by SKGleba]
Press [Cross] to accept the terms and start the downgrade
[Error 0x80010002 opening ux0:app/MODORU000/PSP2UPDAT.PUP] indicates the firmware you are attempting to install is lower than the factory firmware of the PS Vita. Try a higher firmware version.
The Modoru 2.0 menu will be replaced by the green update screen
Your PS Vita will reboot when the update is finished, check [Settings] -> [System] -> [System Information] to confirm your new firmware version

You have now successfully downgraded your PS Vita’s system firmware, you can now prepare to install the corresponding exploit for your new firmware.

If you have downgraded to 3.60: follow this guide to install HENkaku + Ensō

If you have downgraded to 3.65: follow this guide to install h-encore + Ensō

Remember to restore your plugins after installing your new exploit by renaming the /taibackup/ folder back to/tai/ in the ur0: directory via VitaShell.
