How to read write golf 7 edc17 eeprom(maps) using Ktag and Kess?

Have Golf 7 edc17 to read and write the mod file, how to do with Ktag and Kess?

With Ktag: 
If you want to write your mod file by ktag you must open ecu and connect it on table.

With Kess:
if you want to write your mod file by kess obd, you must have vr file for your ecu, mod it and write by obd with kess.
Even you just read one of memories where the maps are and somebody modified that you can also write with kess.
Just pick your MOD file, then, open this on Kess (Maps place) and choose wirte.
If anything is wrong, the Ksuite will say to you before write (for exemple: wrong checksum).

If you need VR protocol, google search or contact at @ Dolcevita (cartechnology.co.uk).

Thanks.

Kess v2 Clone on Ford Focus 1.6 TDCI MK3 EDC17C10 CAN ''checksum error'' solution

Car model and ECU type: Ford Focus 1.6 TDCI MK3 EDC17C10 CAN
Using a Chinese Kess v2 Clone

Error: ''checksum error'' every time when reading my ECU.
I updated my DLL files and today I managed to read the ECU without any error's.
But now when I try to check the file with WINOLS or ECU Titanium all I can see is that the file is empty.

This is my original ECU file

Working solution to empty file 
1. for sure its not empty.

2. Working solution to ''checksum error''
I replaced the DLL's from the attached file.

Suggestion:
Bought a second one kess v2 5.017 with a red PCB. It works fine.
