    Hello gentlemen, gentleladies and gentlenonbinary characters. I recently updated my Nexbox A95X (s905x chipset) to an ATVExperience ROM and now USB Burning Tool no longer loads the device. Samsung 622 klmag2wEPD-B031 emmc, AP6330.
    Any gurus familiar with the shorting procedure for this troubled specimen? Can anyone throw me a freakin' bone here?

      Nevermind. Was able to solve this issue by simply simply unchecking the "erase flash" and "erase bootloader" option in the amlogic burning tool

            IF anyone has successfully set it to Mask Rom Mode and detected by usb burn tool (also which version would be helpful), please reply, thanks.
            Just yesterday I did revive a Mecool m8s pro plus 2/16.
            So maybe you have to try the 2 I have in the red circle. Otherwise try any combination of the adjacent 4 pins.
            You may have to connect the power adapter (at least that was the only option in my case). So the right order is:
            - Start UBT. Load the image file. DO NOT press "START"
            - Connect the cable while shorting the 2 pins. You may have to do this for 5-10 seconds before you get "Connected" at the UBT.
            - Now connect the power adapter
            - Now you can press "START".
            ****Use Usb Burning Tool version 2.2.0 https://mega.nz/file/E0MHyaDa#n5BHOV...RLgesKTiiuwFzY

              And u plug to the usb port closest to the micro sd slot yes? also my box is bricked, was your bricked when you tried it?, because if its bricked i think u need to figure out the pin on the Rom chip i think. not sure tho.

                No I used the usb port near the corner (not the one in the middle and close to the micro sd port !!). On the other hand I do not have the same TVbox as you (actually it is not mine but a friend's, whom I am helping - I will give it back to him today).
                I bricked this Tvbox many times (probably more than 15+ times) because I tried any possible custom rom (mainly Android9).....sadly none of them was proper for this.....so finally the only rom that I was able to use was GI LUNN (7.1.2 AOSP or ATV)
