T8SG Issue.. help need

I bought a new T8SG V2 Plus and second turn on it show blank screen. I follow deviation forum and manage to make it back yestrerday. However splash screen does not show up and show "Channel:3 and safe level:100" box instead. So today first thing in the morning I recopy the nightly builds firmware but half way transfering T8SG turn off.

now I can't see the transmitter in device manager or window explorer. and the screen shows only dot and line.

Can anyone here can advice me what can I do?

Now i holding the turn on button and it show USB unknown device in my device manager but I can't do anything here either still.

Thank you.

If the transmitter turned off during the install process then it probably didn't finish correctly. Follow the directions in the wiki to make a full install.

Thanks hexfet for the advice. however the transmitter now cannot connected to my pc now.

I am seeking help from Jumperxyz.com directly.

I will updated in the forum again if I solve my problem and how I solve it. I just worry I can't solve this issue.

Start in dfu mode with button pressed, than flash latest nightly with dfuse. Restart in usb mode Format your devo drive and copy the filesystem, from the nightly.
Always disconnect nicely and use disconnect "usb" in windows,prior to unplugging. (just to be sure..)

Thank you Fernandez for reply my thread.

Well, they found out the motherboard is faulty and will send me the new one with some cost. I also not sure if I should pay for the cost.
