Old firmware back

Hello, to ALL
will not apologize for my English but I’m Greek.
How do I reset the old firmware (when i had buy  the device was in 1.1.12) and put the 1.1.10 … I want back the old that I had (1.1.12) that is made?

There’s no official way to do it but if you manually edit the firmware revision then you should be able to do it.

The elements play doesn’t work that way.  

it’s only a single binary IMG file, and that’s it

No VER file on the EP’s or MINI’s.
