NAND Chip Mask ROM Mode Short Location

i try help wpra3, ...bye bye

I do not know why you say "plug power", but the most common process is:
- Start USB Burning Tool. Load your firmware and press "Start". Connect one end of your cable to your laptop/PC.
- Your TVbox must have nothing connected to it. While shorting the 2 pins connect the other end to the USB port of your TVbox (most usually the 2.0 USB port-- but sometimes the 3.0).

To short the 2 pins you can use the tip of a small screwdriver.
And yes you should try pairs from 4 to 8 (ie 4-5 or 5-6 etc) or at the other end (continue numbering anti-clockwise) 28-29, 29-30 etc.
If I had the numbers of FORESEE (a better photo of it) maybe I would have been more specific, but just keep trying for each pair (carefully)....nothing bad will happen......

Hi, really appreciate your help!

Okay, for some reason my board is a bit weird.
It seems that most boards only need a usb connection for flashing, but mine is a bit more work.
I have to use the USB port that has "Download" written next to it, which is next to the sd card slot, hold the reset button, then plug the power.
If I did it correctly, I can see the device on AML burning tool.

As for the connection, I used USB A to USB C cable, and plug the USB C end to my laptop.
Please note that before bricking this device I tried to flash with atvxperience to this tv box.

As for shorting the pins, I've tried to short all the pins that are adjacent to each other. i.e. 1-2, 10-11, 11-12, etc
I have not tried to short pins that are far apart though, as it has a lot of combinations.
The procedure I used is also the same:
1. Plug USB download side
2. Hold screwdriver that shorts the pin
3. Plug in power
4. Wait a bit to see if it is recognized by the PC.

I also noticed that when I first try to short the pins, shorting some pin will cause a beeping/hissing sound (I do think its an inductor noise since the board itself doesn't have any speaker/buzzer). But now, the noise is gone.

Can you give a cloce up only of the FORESEE module (the one in the red square)?

short and plug usb port and power
or pin 5-6 on emmc

Hi, thank you for your reply
I tried to short those 2 holes, even ground them, but nothing appeared.

Hi, I've tried to short the adjacent pins on the nand, even shorting each nand pin to the ground with no luck, any idea which pins to short? Your help is greatly appreaciated

That's the processor and RAM, but not the NAND memory
