Ok guys, the tl;dr is in the title.
The tablet is a Lenovo TB-804X running android 7.1.
To add a little bit of background:
When I turned on the tablet this morning it refused my password and, after a second failed attempt, left me only the option to factory reset it.
I didn't think much of it as it's a new tablet with not much data on it, so I reset it.
But I'd forgotten the SD card full of stuff I transferred from my previous tablet that I don't want to lose.
The card is encrypted to be readable only by the tablet as an internal memory, so I can't open it with a computer (tried windows and parted magic), and the freshly reset tablet says it can't read it either.
So I have 2 questions for you fellow anons :
1. If I re-encrypt the tablet with the same password as before, will it the be able to read the SD card ?
2. If not, is there another way to retrieve that data since I have the password ?
Yes, I know how to Google and I know how to post in specialized forums, I also know that anons here reply faster and with more insight (as long as they don't tell me to cover it with butter and microwave it for 15 minutes to unlock the ancient powers of Grayskull).
