It so happened that I removed the Tinker OS (Android) and now when you connect it to the monitor the screen is black and the PC can not recognize it can you help me install the OS in Tinker ?  I found out that Android has its own utility type(BIOS) on the phone it turns on when you press the appropriate buttons but since I work on the Tinker it becomes a problem !

Hello Сайдо,

 

      I'd have to have a bit more information that that, however, if the PC cannot recognize it, then perhaps loading an SD card with linux can allow you to boot the SD and flash Linux to the eMMC.
