Hacking How do I remove TNV?

[ayy lmao]

It was fun having to hack the vita but now I want to play online on it. My vita is at 3.55 and I want to update to the latest firmware. How do I remove TNV? If I update, I heard that TNV can not be erased and it will just say error. I can't use content manager because I need to update but I need to remove TNV first. Am I supposed to use qmca to erase it? Where do I download it?

Just delete the bubble from the home menu and delete your TN-V savedata via Content Manager?
That is something that has worked in the past with me every time; just to prove a point that it does actually work.

Also, when just managing content on your memory card through the Vita, you won't be prompted for an update.
