NAND Chip Mask ROM Mode Short Location

[SakiCZ]

to soldiaz, thank you for your effort !! I was able to do it just hour ago.
Thanks to this topic of the forum I gathered info, tiped out exact same location you marked, and follow procedures to complete succsses.
So thank you and others for crusial informations and guidance.

Venz v12 Ultra SOLVED. Short pin in the area marked by soldiaz, exactly I do not know.

for upload the stock firmware is needed to first import img file into AML Burning tool and press Start button only then plug in USB into box.
Box must be unpluged from power source, must be used only USB port closest to the back side of the box and reset button must be pressed, only like this it goes errorless till 100%.

Hello all. Could someone tell me where are the pins to short to erase the NAND chip? See my photos below. I have a special version of Abox A1 Max 2+16. RTL8723. The chip is Kingston 2400096-001.A00G KE4CN4K6A
The legs of the Kingston chip can't be seen. I drew a green box in the photo.

BGA board..try any pin within indicated area damage almost impossible...

you can use use soldering wire to ground to SD Card ground or simply any wire

Maybe you could ask Google for pin out of that NAND.

Last option: scratch little bit off surface to be able to short copper lines BUT really ultimate last option!!!! :-P Guest

Hello everyone. I am an idiot. BTW great job with some issues here I read all pages.
I have Venz v12 ultra (s912, 3GB/16GB).
I installed custom ROM Redpoison v2 via SD card burner, success.
But after flash this ROM I realized that box does not boot from SD card (toothpick) anymore.
I need this feature for my Coreelec setup.
So I decide to flash stock firmware back. But box did not react on reset button anymore.
I downloaded boot app from google play and booted to recovery, VICTORY, finaly relief.
In TWPR recovery a did standard wipe, but I could not find stock .zip file to install anywhere, only .img, CRAP.
Big Idea hit me, I checked out advanced TWRP wipe options and I did erase all possible in there,and rebooted.
Supprise, SD card is still not booting, USB connection to PC not recognized, recovery mode (reset button) no response. It is stuck on red poison logo screen.
I guess I succssesly deleted all including bootloader.
AS a result, my wife kicked my stupid ass, jeez.
I am broken and seeking for help now, I suppose Mask Rom Mode is only option.
Thank you for any help.
