Primarily, SD2Vita is just a micro SD adapter inserted into Sony's standard PS Vita. However, it adds some charm with its ability to offer more and cheaper memory for gaming. Thanks to the advances made in SD2Vita, players can now expand their external memory storage to around 256 GB. I have to buy new SD2Vita cards because one didn't work and the other stopped working after I removed it and reinserted it into it.
Now, like any new technological advance, SD2Vita had to face some challenges since its inception. Other software applications from other manufacturers make modern gamers prefer the SD2Vita to Sony's own cards. Also, if you use internal memory, I think the tai folder will be in ur0 and not ux0, but make sure to do so once you start installing SD2vita. My PS Vita has a version 3.74 (with the SD2VITA adapter recommended above) and I followed the instructions precisely.
I also used the default settings of the plugin, but I didn't see any indication that it would have worked like in step 11. Thanks to the advancements of SD2Vita, players can now expand their external memory storage to around 256 GB. You can leave the Sony memory card inside and remove the SD2Vita, but it seems that something is wrong with your Sony memory card. Now, reinsert the SD card into the SD2Vita adapter and insert it into the PS Vita, then restart the PS Vita. Yes, you can change your licensee to um0 so that you can play with your SD card whenever you want to play with it, with the sd2vita card, change it again, it works for me.
I've been trying to upgrade to a 128 GB micro SD, but when I copied everything, from the 16 GB to the 128 GB (all hidden files and folders, etc.), the sd2vita light blinks when it starts up, but the vita shell and h-encore disappear from the Vita screen and it doesn't recognize them at all with a 128 GB card. However, we have also worked hard to ensure that we now manufacture advanced printed circuit boards for the SD2Vita adapters. Although the cost of SD2Vita adapters is constantly changing, these adapters have been shown to be cheaper to buy compared to regular Sony Micro SD cards. Either way, it would work, but it's probably faster to install sd2vita and use the microSD card (because there are fewer things to transfer).
