Since you have Blue Board short these pins:
**Edit:
- Always use USB 2.0 of the H96 (the black one)
- Use UBT version 2.2.0
- NO additional power is needed
- Use the shortest cable. Make sure that World Cup Drivers are installed

Hi friends!
I'm new in this forum. I have an Amlogic S905W based TV BOX. I brick this when i tried to install TWRP on ATV Experience 3. Now, it stuck into boot logo on a infinite loop. It cannot be detected for Amlogic USB Burning Tool or Burn Card Maker. I open it to try put into download mode by shorting pins, but i don't know wich one is which.
Can anyone help me to find those? I bring you some photos. Sorry for my bad English!!!

Dear Ath156 and other that can give me advices ;-)

I tried several times to flash my tv box as is https://forum.freaktab.com/node/6376...583#post828583
... normal way and in "nand mode" without succes :/

I bought my tv box week ago and I didn't check usb 2.0 port and it looks broken ...
Any connected device: pedrives, mouse aren't detected. They work in usb 3.0 port.
Tv box power on to boot mode from this usb 2.0 port.

Is there any way that i can fix it or check something or should I return it to the seller ?

Hi guys, I'm so happy to have found such a thread, my device is also bricked. I wanted to ask myself because I couldn't find a photo or short circuit information of my device. I would be very grateful if knowledgeable folks could help with this.

SOLVED I found the short circuit with my own means. I added a photo.
Plug in the otg cable while holding the power button and reset button while touching the pins.

I hope you did not do any "hot-plugging" with the HDMI cable and so you burnt the HDMI port !!
If you have an AV port try to connect it through it with a suitable cable.
Otherwise keep trying pairs of possible pins that will initialize NAND.
