I tried to enter in to recovery by pressing reset button in AV port but nothing is happening. It simply boots to that yellow screen again. The decided to flash stock firmware using Amlogic USB Burning Tool 2.0.7 and 2.0.6. Tool recognises the box on HUB3-2 but gives error "[0x00101004]Erase bootloader/Lowper/Identify/Error result"
Now able to figure out how to proceed further. Please help.
Thanks in advance.
