You don't answer to my mail, your last answer was on 21 november. I have the same problem as describe here.
On my Sbrick with hardware version 4 : - One SBrick update in 4.20 where all port work- Two SBrick update in 4.20 where A port doesn't work on both. When go foward, nothing, when go backward led is lighting
I'm one android app v4.4 update 3, last available.Hardware : 4Firmware : 20
All of my SBrick in hardware 5 work well.These two 4.20 SBrick worked well 5 month ago.
Please give me a solution, I need these SBrick.
