Problem with A13_android_8G_NAND_LCD_800x480_EN_third_release

[enertik]

I have an app running in android in a A13-OlinuXino Rev.G made in Bulgaria, 2015 with image firmware "A13_android_NAND_LCD_800x480_EN_second_release.img".

I've received a new board with the same specifications (I see no differences between) but in this new board I can't install that image, I have to install "A13_android_8G_NAND_LCD_800x480_EN_third_release.img".

The android runs fine, but the app I have don't

Does anyone know why I can't install the "A13_android_NAND_LCD_800x480_EN_second_release.img"?

What differences exist between those images?
