It's not a decryption error, the file was corrupted. How did you download this file?

It's not a decryption error, the file was corrupted. How did you download this file?

Steps I have taken:

0x000000e00000-0x000001600000 : "usercfg"

=> nand read 0x80060000 0x000000e00000 0x000001600000

NAND read: device 0 offset 0xe00000, size 0x1600000
read:1,off:e00000,rwsize:1600000,maxsize:f200000
23068672 bytes read: OK

=> tftpput 0x80060000 0x000001600000 usercfg.bin

Using eth0 device
TFTP to server 192.168.1.100; our IP address is 192.168.1.1
Filename 'usercfg.bin'.
Save address: 0x80060000
Save size: 0x1600000
Saving: ######.....
done
Bytes transferred = 23068672 (1600000 hex)

I enter usercfg.bin into binwalk, I get db_user_cfg.xml

Great, Carlos!

So the tool works fine with files containing payload 6...

Where was the file corruption problem?
