The firmwares in this thread is only for the device ("black" or "white") sold by : http://www.ereader-store.de/
. Booxtor works for this seller.
You could not use this firmware with the "black pearl" sold by : http://artatech.pl/k
. The devices of this vendor are locked. Maurice13 works for this seller.
