Hi there, I know you probably get alot of these posts but I desperately need help! I have the 7-inch iRobot A9 and it will no longer boot, it does absolutely nothing, just black screen. I have already been doing research around this forum and others but I cant quite figure out what to do, I have read about creating a bootable sd card through Linux and such but the links to the amlogic site just 404 and I cant do it. Unfortunately my profession is hardware not software so I dont mind pulling it apart to access the serial interface I heard about. Thanks for reading this post and if you have the time then thanks for your help.
