now it's too late i guess i damaged the flash chip i also remember when tv-box was working i coudn't erase the flash in maskrom mode this happened after erasing and flashing a few custom ROMs which were working fine till the last ROM which bricked the tv-box when i turn on tv-box there is no hdmi signal only blue light
OK here is the correct 2 pins to short (in the red circle) !!!
I saw a guy take a screwdriver and start touching pins until he found the right ones and his box connected in a video. I would never do something like that nor recommend doing it. I just mention it because it would seem either he was extremely lucky or it's not as hard to destroy the chip as one might think. Probably a bit of both.

is it possible that i damaged flash chip by touching other things here and that's why your solution don't work ?

Male to Male USB 2.0 (Type A to A) 1m and Male Type A to Micro USB Type C 1m
To take out of the "equation" problems because of the cable either shorten the cable to less than 30cm or even better make a new one DIY. Most of us have spare/useless cables around (from old smartphones etc). Cut the USB-A male part of 2 such cables and connect the 4 inner wires color to color. A DIY cable better do it less than 15cm in length.
Hi guys, I'm so happy to have found such a thread, my device is also bricked. I wanted to ask myself because I couldn't find a photo or short circuit information of my device. I would be very grateful if knowledgeable folks could help with this.
R-box 4K - RK3229 Thank you all.
SOLVED I found it myself I'm ,sharing it to help other people. Connect the otg cable while short-circuiting and pressing the power and reset keys.

Use a short USB-A male to USB-A male Cable. Not type C. Also try different USB ports of your laptop (not all of them provide the same power !!!). Also if you are using a PC, better try USB ports at the back (beside the motherboard).
ok could please tell me which exactly two short points should i connect

btw my tv-box shows blue light (not red) not booting no video (no hdmi signal detected)
I hope you did not do any "hot-plugging" with the HDMI cable and so you burnt the HDMI port !!
If you have an AV port try to connect it through it with a suitable cable.
Otherwise keep trying pairs of possible pins that will initialize NAND.
