Can someone help me or tell me if it is possible to do.

Dear,

Nice to know you. We fix many bug on the nre firmware, the newest firmware will have better performance. So my suggestion is that you can upgeade the base, don't downgrade the base.

So please upgrade the base to the firmware. It also support Share Line on the frimware.
