What was the reason the pendant was removed from the original controller? Same issue?

The pendant on other robot had problem and we change the pendants, the pendant on the new controller become update and when we connect it to old controller it was update but it give these message in update process.

The problem is in yppmain.zip file, maybe this file in SD card of cpu unit broken or deleted.

When the pendant want to upgrade, use this file and when it couldn't read give this message.

Check the SD card of CPU unit in the YRC1000 and search for this file.

Thank you TSGIR

I check the SD and see there isn't yppmain.zip file in it. I check on other robot and copy from it to this SD card and problem solved.
