Seems like you did not read the instructions and flashed 1024*600 screen resolution instead of 1280*720. At least black screen says so. Put the correct oem.img and re-flash the unit again. Actually it can be done using usb stick, but your device is disassembled and it is faster to shot a resistor one more time. If you have some specific error in MASKROM mode, please show it to me.Hello sir, actually you were right and I got worst then your case, i didn't found any isolation there, so I did like you and the blinking buttons stopped but I think I wasn't lucky because after assembly I got a black screen without anything showed, except when I connect the usb to the pc i got maskrom mode but I cant pass the flash.
I think I maked the situation worst when I tryed to flash with this iasue.
What do you think I can do now and thanks a lot anyway the results, you do a great work sir.
