    Hi mAtvXk, thanks for the reply. The two copper pads did not work. I tried to the best of my abilities to have good contact but it was not detected by the Amlogic tool. I tried both of the USB (2.0 and 3.0) ports on the device and both did not work.

    Try with two copper dots, make sure that you have good contact.

    Hi all,

    I have a T95 Max+, S905X3 processor, 4GB RAM and 32GB internal storage. I managed to brick it while booting up with Emuelec. I made it work before but I don't know what caused this issue. I tried pressing the reset button to enter recovery mode but it did not work. I am hoping that the mask ROM mode will work out. I've attached pictures of my board. Any help would be appreciated, thanks.

    sorry, I presumed that I will see pop up window "new device" in the right corner of laptop screen, so I tried to short pin it while watching very important game of IIHF ice hockey world championship. Loud room at the moment. So I've missed the tudu sound when it was finaly connected. However I tried with needle and wire only in marked area, so no much options to try.

    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%.

    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 mAtvXk

    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.
