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?

I managed to unbrick it. First press Erase, then press Blank to verify the chip is empty, then load the 8MB file from the bios update zip and press Program.

 

Hm. Tried that again, Erase, Blank, Write, Verify without any Errors – no sign of life until now. I think I’ll leave the tablet on the charger for some hours.

I had the “black Screen, no LED, noch charging” – issue as well (S/N PQ32G221604) and just programmed the bios with the SPI-adapter. First the official Bios from the Chuwi-Forum, after that the one with the fix for the SD-Card. Both doesn’t change a thing – any hints for me?

Battery is 3.7 Volts (when disconnected from the Mainboard). USB-Current is arround 0.15 Amps @ 5.1V when plugged in, but no led etc.
