After flash is end gps stuck on step 4/4. After 1 hour i reset device and now screen is black,no usb connection. When i push button ON and Reset nothing happend. I cant flash again with SD card becouse i cant turn on device. When i add device on power orange light turn on but when i disconnect device from power orange light is still on but barely visable. I try also with atlasmgr but wont recognize device. I try all that i think of but gps wont start. On chip is writen HY27US08121A TPCB 822A M7SC438181 I google but i cant find solution. Can anybody help me tu bring this device alive?
