Yes I had the same error. I didn’t back-up anything form the laptop since I though everything will be smooth. I tried typing “exit” and it just loops back. I also tried a lot of CMD commands as taught by my mentors and seen in the net but I still failed. there is no Boot manager and I cannot create a boot manager even I reconstruct (which is very tedious and time consuming) from a running laptop.
I also tried the Yepo 737S reset here “RESET” but the error still prevailed. Luckily I was able to refund the product but I really like that laptop; the sturdiness and quality seems very fine and it doesn’t heat so much unlike what I read from others.
My cousin who is IT said that its probably has missing drivers that was originally installed prior fresh reinstall; or that Win10 had caused an error and affected somehow the eMMC reader which is bad.
By this I’m afraid to try the Jumper EZbook 3 Pro itself as I may encounter the same problem from that unit. I do not want to refund again.

By the way I read your post on the thread you linked.
It happened that I had an M.2 SSD with the unit I purchased. I tried reinstalling the OS on the SSD and still I end up with the EFI error. I also tried reinstalling without the SSD and still EFI error. I almost tried everything, but I guess there should be a driver to be installed while in recovery mode to make a boot manager that the EFI can read to boot the OS installed, but before i tried, I already have the unit refunded for warranty purposes.
Hope my input helps.
