Let’s clear this beforehand; this utility doesn’t allow you to DOWNGRADE your firmware. It could however get you out of a sticky situation if you like messing around with your Vita’s system files or its registry. Thanks to ‘SilicaAndPina’ (yes, he’s the controversial VPK guy; give him a break, he’s done some cool stuff and he’s another human afterall) and ‘CelesteBlue’ (the ePSP bubble installer, i.e Vita Activation without PSN guy); your Vita’s got semi-comprehensive life insurance.
What’s Firmware Reinstaller?
It’s a utility that obviously requires taiHEN which allows you to reinstall your current system Firmware which is 3.60. This is especially useful if you’ve deleted or modified some system files or used the CEX to REX convertor and wish to revert back to stock 3.60. You needn’t use this homebrew unless you’ve messed something up so unless you need to reinstall the FW, I’d recommend you stay away from it. As an extra, you’ll get an added ‘Update Via PSVita Card’ in safe mode to reinstall 3.60 from safe mode if you’ve reinstalled your FW at least once with this utility. Obviously, you need access to safe mode to reinstall so don’t go thinking you can do stupid things such as nuking system partitons.
Installing this is pretty straightforward, simply follow the links below. This is of course a utility that needs unsafe permissions so get the VPK from a trusted source. You should check the source code linked below if you’re skeptic that this homebrew will harm youe Vita and compile it yourself. Make sure you file any issues you have on the GitHub page so this homebrew becomes as bug free as possible.
