Bricked Tox 3 Tv Box - help with recovery

Help & Support Recovery
1

Dear Colleagues,
I have managed to brick a Tox 3 Android Box with a s905X4 Chipset.
I attach three pictures of the circuit boards:
S905X4 Amlogic Board Tox 3 Android Box - Album on Imgur

I’m not sure where the NAND Flash chip is in order to use the short pin method?.
Any help is appreciated.
Thanks

you maybe must remove the cooler to reach the second halve of pins to use the short pin method

Dear Moglyn,
Thank you and appreciated.
Can I ask:

  1. How do I remove the heatsink as there are two (that look like) black bolts at the top and bottom corner. Picture: Imgur: The magic of the Internet
  2. What is the TTL for?
  3. What’s the best ‘accurate’ tool for shorting the pins ? (is there a specific electricians tool for doing this).
    Thanks.

1 They are plastic/spring loaded, flip PCB over and use needle nose pliers and pinch tabs to push out./ try not to cut them off so can be reinserted

2.TTL is for U- art serial communication

3.some like to use Automotive 12 volt tester/probe has a fine point on end
