To Find RX TX for Firmware Download
Please help me find the RX TX(UART) of this hardware for me to download the firmware using the U-BOOT.

Blurry photos aren't helping  ;D

What you'll need to do is lookup the datasheet for the chipset used (looks like a Hixxx device, so Hisilicon), and see what pins are the rx /tx for the chip, then trace those on the board to see if there are access points.

Looks like the bottom 5 pins are likely ones (from the IMG_1900), but you'll need to buzz out to check.

Did you figure out the RX/TX ?

If not, please upload a clearer picture... I just went through this myself about a week ago, so i'm willing to help.
