Thanks for your reply
I use GA-J1900N-D3V, it is onboard CPU J1900 (BayTrail) with Dual LAN RTL 8111F
Last time all 0.13b loader(3 differnt, std... syno... recov...) changed driver fail, and I have tried 918+ and 3617 one, that means I've tried different loader with differint driver patch at least 9 files, I don't event know what type would works...
Later I will try recovery 0.13b one again, use 3617 version (change two 3617 file from pat file 24922 version by hand) and try add driver, too (that means I'll try 3 differnt bootloader). If it still doesn't work, I will try to see serial port message......(I don't have RS232 to USB line yet)
