question abt modchip and bios
 

i don't know what modchip am i using it said unknown in the evoX , could i flash my bios to 4981 or i must use X-ecuter2 to flash to 4981 ? Sorry my english not good.

Should be able to flash your modchip with what ever BIOS you want. As long as it wasnt one of the early modchips.

i think i bought my xbox 1 and a half year ago . that means is a old modchip right? will i screw up my modchip if i try to flash my bios with 4981 ?

wow, you should find out what chip you have before flashing. The older chips connot be reflashed.

but i don know what modchip am i using i think is a homebrew modchip .
