VitaTweaks VS PSVita-StorageMgr

Download Enabler Allows the user to download any content from the vita web browser (The FloW)

https://manuals.playstation.net/document/gb/psvita/settings/signin.html BUT the vita will then nag you about trophys. to avoid that use NoTrophyMsg https://github.com/TheOfficialFloW/VitaTweaks

Download Enabler Plugin + public domain movies from archive.org?

Yes. It’s called download enabler. You can install it directly with AutoPlugin II, or visit the GitHub page

There’s a no lockscreen plugin: https://github.com/TheOfficialFloW/VitaTweaks/releases/tag/NoLockScreen but you need to put it in ur0 but you may be able to bypass that by putting a tai folder with it in ux0 and a config.txt

Only one i could think of, would be to manually add this Plugin to your config.

I use a pluggin to disable the Lock Screen because I hate having figerpringts!

I dunno. But you can try and use https://github.com/CelesteBlue-dev/PSVita-StorageMgr instead. It does the same thing, just in another manner. I had trouble with yamt, so I still use storagemgr to this day

Storage Manager A Kernel plugin that automatically mounts/redirects any storage device to any mount point; Popular plugin for mounting sd2vita (CelesteBlue)

Don't use USBMC, rather use storagemgr (https://github.com/CelesteBlue-dev/PSVita-StorageMgr) as it's "newer" using some of the usbmc code (or YAMT? yet I haven't actually tried it with an HDD)

Do you have the plugin for sd2vita, set up properly? Are you using YAMT or storagemanager? Has the 64gb micro sd been properly formatted to work with the vita's sd2vita?

Which sd2vita driver (plugin) do you have installed? YAMT or storagemanager? Or did you install using vitaDeploy?

Also I think its time for you to move away from "gamesd" and move to something more modern like yamt or storage mananger.

StorageMgr and yamt. Both has its advantages and disadvantages. I find, storage manager for ease of use, yamt for better read speed. I say for now, use storagemanager and once you're familiar with the Vita and its working graduate to yamt.

When on 3.73 you can only use Storagemgr.

The more involved guide says to use storage manager, given how messed up your set is currently maybe use this until your more comfortable and familiar with the Vita and its set than move to yamt later. Remember that the sd2vita should be ux0.
