[Samba SM35-J-T20 does not start up after update]

Hi !  I tried as R.Moses guided and succeed to install  BinLib and Boot

Then tried to install OS , but it got error on PC screen during update. 

 

Contacted Unitronic Tech support and from there got an extra tip:

Try as follow:

1. Turn off the PLC
2. Touch and hold the screen.
3. Power on while screen is touched.
4. You will see a countdown on the PLC screen.
5. Touch the HMI screen twice . The countdown should have stop.
6. On VisiLogic configure the communication settings with a baud rate of 115200 and a timeout of 1 sec
7. First  update only the BinLib
8. When BinLib has finished updating, please update only the Boot
9. When Boot has finished updating, update only the O/S.
10. Download a blank project

 

Tried many times to update O/S, but it stopped during install.

as last effort I just refrain using computer, went to have dinner and when came back, it was OK
