NAND Chip Mask ROM Mode Short Location

Is the tablet bricked, did you do hard reset, re-flash firmware...???

Hi mAtvXk. Unfortunately, the video you posted has no effect as the tablet is not recognized by the PC. Unfortunately, the only way to bring the device back to life is by short circuiting.

I got a a95x f3 Air that doesn't boot (only red light), flashing stops exactly at 3%
I'd like to mention that the problem started when I forced shutdown the box by unplugging the power, because it just froze and didn't respond anymore.
thank you

...Hi I have a Mediacom 875 s2 tablet and I should test point. Can you tell me the right pins and what should I do? these are the photos of the motherboard...

Help to bring MXQ Pro 4K back to life

Thank you for allowing me joing that great forum.
I really need your help to make my MXQ pro 4K comes back to live . Story started when the box was stoped working and didn't boot or even had its Led on . So I plug it into my lap top tring to use hrad reset by toothpick , OTG usb port and downloading the firmware for AMlogic (thinking thats the correct chipset for that type of boxes as shown on interent). But the burning tool couldn't see the box . So I guess the box has different chipset and my guess was right so I used the tool for Rockchip and downloaded two frimwares for trial. the first firmware was upgraded but the wifi wasn't working then when I try the second firmware the box totaly died no Led no detection on Rockchip tool. At the end I decided to open the box then was the surprice I found that the chipset is Toshiba I tried to short the pins but no luck . Please see attached photos for the mainboard so grateful if someone can help me to bring that box back to life.

Hi Guys,
