CubeOrangePlus No parameters loaded, stuck on STAT_TIMERUN

Hi guys, I’m did some parameter changes in Ardupilot firmware and load on my CubeOrangePlus, also tried to change SRx_protocol/baudrate..

Now when I connect to GCS (Mission Planer/ QGC / Mavproxy) I can nnot get the parameters list, the FC returns only STAT_TIMEOUT , and if I wait long enough , I can get some other paramteres (not all).

Example on MP:

And on Mavproxy parameter editor:

I tried to reset default parameters, but the Cube gives no response, and I know parameters are currently not be changed by GCS request. Loading official firmware versions does not help ( built with waf on LInux or loading firmware by MP)
