MK802IV ap6210 bricked?

[morfarj]

Hi everyone. I recently tried to install new rom on my MK802IV, it did not complete and now it says mask rom mode, but i can't flash anything to it. I tried the switch button without luck, i tried reinstalling drivers, other usb port, other computer etc.

I can't flash anything to it, also tried clear idb. it says download IDB failed. Tried both Androidflashtool and RKbatchtool. What can i do? Is there a way to short circuit nand like other devices?

Thanks in advance

Pins to shorten for unbricking

Is there a way to short circuit nand like other devices?
Thanks in advance

Just some minutes ago i unbricked my 802IV (16GB, AP6210) by shortening PIN 7 and 8 on the NAND flash.
I worked, so i can now flash more custom roms until...

So you shortened the two pins, while holding the reset button and then put the device in the usb port in the pc?

Only shorten the pins (without holding the reset button)
