This is my first time posting here and I am not sure how to best classify this question with tags, so please excuse me.
Here's the problem: I have backed up the data partition with TWRP and then wiped my Note 10.1 2014 before installing a fresh stock ROM. I did this because it went into a bootloop. When I tried to do a restore of the data partition through TWRP it sent the tablet back into a bootloop, so I had to redo the wipe and installation. I am only really trying to get one thing from the data partition, my S Note notes, so I thought I'd try to do this manually. I unzipped one of the TWRP backup archives (data.ext3.win001 or something like that) and found the folder com.samsung.android.snote in there with the .SPD files inside.
However, the .SPD files actually appear as folders on my Mac, not zip archives as they should be. Something must've gotten mixed up in the TWRP backup. They contain all the appropriate files, and they are of the appropriate size, so I thought I'd zip them on my computer, change the file extension and put them on the SD card and back into the phone to be imported into S Note. However, S Note says "Invalid file format" when I tried to open them.
Does anyone have an idea about how S Note files work, and how they can be correctly zipped, give that I have all the correct contents? I know it's a long shot, but any assistance would be welcome! Cheers!
