Is to enter DNX mode.
No problem of “Manufacuring flah Tools” because I can not get to use.
To use the “Flash Tools Manufacturatin” You need to turn on the tablet with “Vol +, VOL- and power” and when you do a text will appear (I guess that’s the DNX mode).
When this text appears you have to connect the tablet to the PC with the “manufacuration Flash Tools”.
I would not that text appears. When I press (Vol +, VOL- and power) appears me “BOM selection switch (SW1B1) Have you changed FORCE_WINDOWS / BOM3 1 mode”. This error is 3 seconds and then start Windows.
