Psvupdatpup Download Patched [verified] -

If a Vita is stuck in an update loop or has corrupted system files, manually re-installing the firmware via a .PUP file in Safe Mode can "unbrick" the device.

When using a patched or official update file for a downgrade, the file must usually be placed in a specific directory on your PC (if using QCMA) or on the Vita's memory card: ux0:app/MODORU000/PSP2UPDAT.PUP psvupdatpup download patched
