Bricked Onda v919 64gb (without 3g) I currently bought a tablet Onda v919 from China. When I received it I realized that the installed android did not contain Google Play, and after reading about it I found out that you could make an upgrade with a later rom to fix this. I followed a guide to do this, but after I finished my tablet will not start.

When booting I enter what I think is the efi console. 

To fix this I have tried to reinstall windows from backup images. However I have not been able to make a bootable usb drive. 

Does anyone have any tips on how to reinstall my tablet?

Best regards

It sounds like you have corrupted your partitions. To fix this you either need to rebuild your partitions (which requires a knowledge of the device and MBR or GPT, and will need know how the factory ROM is imaged).

Or you can repartition your tablet by flashing it with a factory ROM. This will revert the tablet back to its original state. Thus erasing all of your data.
