OK. There are at least 3 different channels for euroatlantic region. Booxstor (Germany), Artatech (Polland) and Russian one.
Firmware from Booxstor is also offitial. It can be installed in devices from his channel and most probably also from Russian channel, but for sure it is not possible to Artatech channel devices. For Russian devices there might be a problém that some configurations are without sound output And maybe even without pen support. On those devices the instalation was not possible. Maybe it changed later on or there is a hack to do it.
Artatech firmware is not possible to install on devices from other channels. Maybe there is a hack to do it, bit normally it shouldn't be possible. Tis firmware seems to be based on Booxstor's, but if it will be li ke that forewer I am not sure. They do not seem to contribute to common development of firmware, they have features, that could be in other firmwares, but are not. Cloud storage for example. Artatech firmware is released much Les frequently than Booxstor's.
Russian firmware, I do not know.
