Answer:

Hi, I finally managed (with some help) to get it!!!...I think!

Explanation:

I changed a bit (to see it more clearly):
enter image source here
So I have:

First bump from A to 1:
Parallel R1 and R2#=(2*2)/(2+2)=1Omega#

Second bump from 1 to B:
Parallel R3 and R4#=1 Omega# again;
Series betwen (parallel R3 and R4) and R5#=1+3=4Omega#
Parallel of the above with R6#=(4*4)/(4+4)=2Omega#

Finally:
series bump1 and bump2#=1+2=3Omega#

...does it make sense?
