Sorry if this has been explained but I'm finding it difficult to find a guide for this. I've asked this in another thread but haven't had much luck. I want to install ARK to my brother's Vita which is already on 3.63. Obviously the savedata can be copied using CMA but copying the pboot is harder. I assumed I could backup the exploit game and insert the file, but they copy as .psvimg files so this is a no-go. I do have my own 3.60 Vita that can be used for this, but I cannot seem to be able to move the memory card from one Vita to the another without being prompted to format. Any ideas?
