Hi, I need the bios file for my Hi13 and the serial number is Q64G45180200856. I have tried I2W6_AP135.037&EC_219 and Chuwi_Hi13_Bios_AP1V114_X64_BIOSEC but they didn’t work. The link of M1W6_AP135_A.064 x64 is broken that I can’t find it anywhere. An email has been sent to service@chuwi.com but no reply. Could you send me the right bios file?
