Hi everyone,
I want to sincerely thank you all for your help and for sharing the firmware files—I truly appreciate it!
I've collected and shared other firmware files, but I'm still looking for a solution for the DT900 ITK-24CG model. As shown in the attached table, the required file is itkisipvc.tgz. If anyone has this file or knows where to find it, I would greatly appreciate your support.
Thanks again for all your help!
