Geekcreit CS-DY transistor tester kit

[galena55]

I have bought on Bangood a Geekcreit CS-DY transistor tester kit.
Where can I find a HEX or source firmware for upgrading it?
I noticed that the LCD display connections are different from the original german project.
Thank you in advance for your replies.
