The right some times chipset also has a small indentation at the 1 pin.

If you look at wifi chip small dent on chip above the dot below it same on the chip to right of the nan

I Upload the photo. the nand; There is no inlet on the chip, wait
only one white cue ball, which should indicate the number 1 of the chip.
Just see the CHIP AP 6330

Confirm that the Chip FORESEE NCEFES78-g is the nand flash?
Because the pins marked USB burning tool I put them together, but it didn't work.

Then AP 6330 is the wifi chip?

Thank you

Yes that is the nan chip. Use Jd method and short pins 7/8 i think but check his post for unbricking again to be sure.

If the post is this, the pins are 17 and 18, also did this, but there are always the same error: Romcode/Initialize initialize USB DDR/Read status/Control setup error.
Can you do more? Otherwise I throw it in the Trash:-(
Thanks

We have the same PCB, just mine writes m82g v2.1, is suppose since it is a 2/16gb
I trid with a cable like this one you sent in the link,and Putty, but has a lot of "noise" in the data received. There are no pins in the PCB for Tx/Rx/Gnd so had to put some hand made cables, didn't want to solder them.

I suppose i am going to send the box back to supplier cause I am not even sure we have a working firmware for the box.

Nasosal, mine is a 2/8 GB of ROM.
My PCB is this.
Which cable?
I haven't tried it yet, but I think it's for this.
