YEAH I got it working! I tought problem was, after upgrading to 8.1.0 I seen Nintendo error screen so I tought there was problem with that process..
But I just read that SX OS 2.5.3 does not support fw 8.1.0 and I need to install 2.8 beta. so I installed, injected payload and my Switch is working!!
