Hello, I have a BIIIG problem. It started of me wanting to root my device. Of course, I used a random tutorial from the Internet. I did the steps carefully, but after a reboot, I had no TWRP, and I had an overlay of Download mode on top of Samsung secured by knox screen. So I downloaded another TWRP (unofficial, but stable), and after a reboot, I didn't see the system booting, I saw TWRP. I looked at file manager, and /storage/emulated/0 was empty, /data was also empty, I tried wiping the data but I have an error: Failed to mount '/data' (Invalid argument), I tried installing SAMFW.COM_SM-A526B_OPV_A526BXXS5EWI1_fac.zip via Download Mode using Odin 3, but it just failed and no file was transported. I need help, because now I don't even have a backup phone, because I had Nokia that is now hard key-locked (cannot unlock the keyboard because it's constantly locking)
