Hi
@FoxKat , it is truly impressive to see the lengths you went to, to try and help the OP with this problem. After a recent absolutely unfathomable experience with BlackBerry, you have redeemed my faith in humanity when it comes to the Android community.
I am in the exact same situation as the OP but for different reasons, and in a somewhat different scenario. Priceless, irreplaceable media on my micro SD card, which I encrypted based on the default prompts I received on Day 1 when initially setting up my BlackBerry PRIV and inserted this micro SD card to expand the phone's storage capacity (
Android 6.0.1; now at Android security patch level May 5, 2017). In my case, my phone was working perfectly well, with all of these files accessible, until I installed a firmware "security" update from BlackBerry at the end of April. Since then, my micro SD card shows as "Corrupted" within the device, but I know that it isn't as at least one other user had an identical issue with the exact same micro SD card and phone model after the exact same firmware update. Coincidence? I think not...
BlackBerry has been of zero help, and could clearly give zero sh*ts about me or my files, despite me even going to such lengths as physically travelling to their headquarters (
with an extra factory-sealed micro SD card that I offered them for testing purposes, to replicate and resolve the issue, but which they declined). I literally have nowhere else to turn and no one else to turn to for help with this seemingly intractable problem. Please let me know if you are willing to help, and if so, I can post some further details as needed/directed by you. Thanks in any case for taking the time to read this post.
