Re: Please! Help me. UG802 Android TV Screen black from UP frimware not complete.
Its quite easy, to unbrick most RK's first click the device open being careful not to rip the wifi antenna off the case! use the RK tool that you uploaded the failed firmware with and run it, Find the nand chip (usually the largest chip on the board! its usually oblong and may have 2 dots on either side the smallest dot represents pin 1 using a small metal pointy object (ear ring, pin, needle) touch pin one then click down 7 pins on the chip (so your pin is between pin 6 & 7 now the tricky bit! with the pin in place plug the usb otg lead into your PC with a standard micro USB lead! It helps if you plug the lead in first and then unplug the PC side just enough to cut the power but still been plugged in then you can just push it when you have the pin in place! the light will light remove the pin / needle and RK batch will recognise your device! am in the process of making a video on this in the mean time you can PM me or Google me aidymp
