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.
