If the BIOS isn’t getting detected by the CH341A programmer, you will need to remove the IC from the motherboard and solder it onto the circuit board that is bundled with the programmer.
THE CIRCUIT BOARD (AFTER ATTACHING THE BIOS IC) HAS TO BE INSERTED INTO THE 1.8V ADAPTER AND NOT DIRECTLY INTO THE CH341A PROGRAMMER
Thank u so much will try and let u know sir but i dont have the bios hex file but i have been using ch341a i can use it to read write but i dont have the firmware its exact model as per your gd25lq64cvig please recomend a firmware also its a dual boot tablet i have have the same issue as imran power light blinks mic is making beep sound
Your best option is to contact RCA support and obtain the firmware file:
Hi10 firmware will not work for RCA tablets, though the BIOS IC is common. Hi10 has 4 BIOS files: 1903, 1906, 1908, 1910, and they only work with the exact model. Flashing the wrong BIOS bricks the Hi10, as many members here have found out
