Bx22D loader LA210 - backhoe BT600

[nhan]

I need help
Recently, I service the hydraulic control block valve.
Stupid enough, I didn't take any picture before disassembling and now in the predicament of not knowing which line goes where.

Numbering is the location on the hydraulic control valve block, and color is refering to the lines:

1 red, 2 blue, 3 green: This would make the loader runs correctly. But the backhoe does not work properly.

1 green, 2 red, 3 blue: the backhoe run correctly, but loader can only operate up and bucket seems right, but cannot go down
My question is , what did I do wrong?

Any suggestion/testing/ debugging I should do?

Thank you very much for your time

To make me even more confused, kubota parts named the lines as:

Red: delivery tube
Blue: pump tube
Green: return tube

Before trying to sort out the connections do you have the 3pt position control lever in the full down position? It must be fully down for things to work correctly.
