So I did some research and still don't know what files I need to get.

Just to be safe, i would like to know what MAIN, FS, and Custom files I should use and why they are compatible.

Here is the info XS++ gave me:

DB2020
CID52
17:29:41| CDA: CDA102774/87 R10A
17:29:41| Firmware Version: R6BE001
17:29:41| EROM: R3A022

I was just wondering if the files i download to unbrand matter. If I do need specicfic files, please explain why.

Thanks!
