VitaRW is a tool that gives you Read/Write access to the Vita protected partitions (e.g. vs0, sa0, os0, etc).
Note from developer:
This is a PoC, and should be used by devs who like the risk. Used improperly, this tool could let you badly damage your PS Vita, beyond repair. If you mess up with the wrong files, you'll end up with a permanent brick and your PS Vita will become an expensive paperweight.

What is VitaRW
If you read the paragraph above, read it again. Then read this: this release is for developers/tinkerers who are aware of the risks. Most people should be patiently waiting for actual tools that have been vetted and beta tested.
With that out of the way, what does VitaRW let you do, technically?
Here's what we know about some of these partitions (from Vitadevwiki):
- os0 found on the NAND is where the "main" OS (aka CoreOS) files are including all the kernel libraries and the most important user libraries. There's always two copies of this for redundancy and updating will only update the inactive partition and the active flag is swapped.
- sa0 found on the NAND is the "bulky" data like fonts and handwriting information. Why is it a separate partition? Because it makes update files smaller. Your "systemdata" PUP provides the update for this partition.
- vs0 found on the NAND is the rest of the OS including all the system apps, the main shell, and the remaining user libraries.
- Hopefully this gives you an idea of how dangerous it could be to change these files on your console. With that being said, according to Major_Tom, SMOKE has started modifying some files in vs0 and did not run into any big issue. Then again, proceed at your own risk.
