It's a long story ... I recently got a MB SD Connect C4 Clone (a low quality one by its looks)
The multiplexer I got shipped with the following firmware:os:2.2.2csd:2.03
When I tried to use the MUX on this firmware in 03.2014 xentry, I am not able-connect to the car and kept getting Erro Rs. So I watched webmaster's SD connect videos and renamed the 3 update folders in C:\Program Files\sdconnect Toolkit and it W orked! Xentry was working well. The problem is when I am unable to get Hht-win to work. After reading around on forums, I Saw this post (post #5) http://mhhauto.com/ Thread-updating-firmware-sd-connect-problem?pid=280705#pid280705-and realized that renaming the update folders could be The cause of Hhtwin not working. A this point, I thought of using Webmaster's method to update the MUX and rename back the update folders to original name. Before updating the MUX, I wanted to rename back the update folders to original and open Hhtwin through DAS standalone and Test if it works-(this is because I thought, only xentry would attempt to install updates to the MUX (which might n OT be safe as using webmasters method to update are safest) so I reNamed back the update folders to original names and restarted the PC and MUX. I opened Hhtwin through DAS standalone and Surprise Surprise, it updated the MUX after opening hhtwin:
The update happened even though I had not inserted any batteries in the SD connect! After the update, the MUX rebooted and Hhtwin were working perfect!
For SD connect C4 firmware update, I referred to:http://blog.mbstarshop.com/2015/08/25/ instruction-for-update-and-install-v2-30-mb-sd-connect-c4-mux/
This is the firmware the MUX was on now:
I tested it with xentry without renaming the update folders and it works well-no more errors. So here I suggest I-but SD connect C4 from a reputable site like Mbstarshop.com, they sells SD C4 with os:2.3 and CS d:2.11.2 of high quality, but for Hhtwin, it must is with software before 2015.12 version or even earlier. Now I seem to recall this may is how my HQ multiplexer got updated to latest firmware (by using Hhtwin in 3.2014 xentry), Although at which time I did not know about MB SD C4 firmware, so I may not have noticed.
How to solve MB SD C4 Htt-win failed to communicate
