With new BIOS I went from not going beyond BIOS screen to booting both operating systems but I have the going black screen issue even after trying the passive thing etc. I am very dissapointed with this tablet.
Besides this, I had delivery delays, the charger died with a big noise and even made my computer turn off, bad support with Gearbest…..
On paper looked fantastic in real life is a piece of crap. Definitely a NO BUY recommendation. Maybe Chris should update reviews with all the issues.
