does the latest stock rom have many problems like less responsive screen and less working top buttons
There are no latest problems. This is an old device.
As I said in reply to your other posts - contacting the vendor who sold it to you, or contacting lemfo customer service are your only options.
When a factory reset does not work. Not flashing firmware. Reset from the settings app on the watch.
