After making the backup I flashed Pac Rom and yet I could connect it to the PC without any trouble.
Now I noticed that Pac wasn't my rom(Flashaholic), I went back to X-Note 18. but now the storage didn't show up(I've got the samsung modem driver installed).
Yet the Device manager shows me that the phone is connected.
After that I reinstalled Samsung modem driver; didn't help so I uninstalled it
Installed kies; Kies didn't find the device and gave an error(Also my device gave a warning that the computer didn't have the right software to find it).
Reflashed Pac rom; which gave me access to the storage just like before!
Reflashed X-Note 18; problem was back again.
So I decided to go back to stock and flashed the official NG1 firmware from Sammobile. which gave me access to the storage again.
Rooted, installed X-Note again. And yet again; no storage.
Is there anyone who can help me out with this?
Thanks in advance!
