**Hello everyone.**I want to downgrade it to version 7.12.2, but its factory version is 7.15.3, and I can't downgrade it using the 'netinstall' tool. Is there any other way to help me downgrade it to version 7.12.2?
You can not downgrade below factory version.
Why do you want to go this far back ?
7.12.2 is from 2 YEARS ago ??
