Ok ok.. I
THINK I have an idea. Try to pull an
mmcblk0.img.. now unfortunately, it'll pull EVERY PARTITION from the WHOLE device and you'll have to unpack it with something like
@SuperR 's Kitchen (I've actually
successfully done this myself with some nougat 7.1 devices, so it
might work for you. Now 1st off, download Samsung drivers from Samsung so that the PC recognizes it for what it really is, should make everything a bit easier as well. Now you have several kitchen options here, but the only one that works for Windows is the paid version ($20, I think..) but that one also works on ALL Windows, Mac, Linux systems and goes back to Android 4.0 Ice cream sandwich to now (Android 11). As for the free ones, they're all Linux and you'll either have to install that is somewhere on your PC, use someone's else's PC with Linux, or use one of the Mint/Ubuntu4Kitchen's to make a "liveboot USB". I recommend the Mint4Kitchen to ppl who're used to the general design of Windows, which has all drivers and pkgs are preinstalled.
Here's a link to make your choices. Personally? I prefer Mint4Kitchen myself and use Mint Cinnamon almost exclusively (less confusing, tbh). This method has been absolutely flawless for me so far, might just take some tinkering on where ya pull to (I would right-click on the desktop to open terminal, also inherently tells the PC
WHERE ya put said file when done.. then use the kitchen to unpack it into different folders to peruse data.. I do apologize for forgetting about this method but it certainly works. Now, depending on the size of the mmcblk0.img vs the PC speed, just pulling or unpacking the .img can take quite a few minutes to an hr (phone storage is getting huge these days but yours shouldn't be too bad, honestly).. hope this is doable for ya. One last thing, when ya go to unpack the mmcblk0.img, you'll get some silly error that it can't find something (like build.props) but don't worry, it'll be 100% unpacked anyways, was just looking for something it normally sees in /System that it won't find in the the other 30+ partition folders. As for SMS/MMS (texts), you won't ever see them in this but the contacts will actually be in your Google account (if it was ever connected to a Google account to begin with). Hope this helps..
