Yep, it’s a dual-boot Hi8Pro and I flashed the BIOS I’ve downloaded from the Chuwi-Forum. I tried both files, the one with the sdcard-fix and the one without. 🙁 No blinking, no charging, just the cpu gets a Little bit warm and the tablet consumes arround 150ma
Since a few days the Chuwi-Dropbox has been disabled, I tried to doublecheck, that I’ve downloaded the right Version. Is there a known mirror?
