Can an incorrect pin factory reset be recovered?

i think that most data recovery programs you see on the web are just scams. most of your data does reside on your system partitions and sometimes on your internal storage. but those usually will get wiped when a factory reset is performed.....so i think you might be sol.

hopefully you had google photos set up. you can have it sync when wifi is available. it will automatically backup your photos without you doing anything. i never have to worry about my photos.....ever.

 

Although it's true that computing devices in general (not just Android) do not actually remove data when you delete a file, just remove pointers and mark the space as free, if the device has actually suffered a factory reset that probably isn't going to help you. The reason is that in any Android device made in the last few years the storage is encrypted, and the encryption key (which isn't, or at least shouldn't be, just kept as a file in an accessible bit of storage) is wiped during the reset. That makes file recovery after a factory reset even more problematic than it is with an accidental file deletion (which is itself not as simple with an Android device as with a USB memory stick or SD card, since the way it connects to a computer is different).

So it might depend on exactly what happened, which isn't clear from your description, but if it did suffer a factory reset I think you've no chance. And even if it didn't I don't think the chances are good (as @ocnbrze says, it's easy to find apps that will claim to be able to recover deleted files from Android devices, it's much harder to find reliable reports of success for them, i.e. claims of success that are not written by or paid by the company producing the app.
