i recently got

ezreader pocket pro ,
when i cheked the website of astak there were available two upgrades
-1. 5" EZ Reader Pocket PRO Astak 12/10/200
-2. 5" EZ Reader Pocket PRO Astak 09/10/2009
i downloaded these rar files , they had two bin files inside them,
but i dont know how to proceed further i extracted and copied these bin files to sd card but they do not show up on reader screen

.
how the upgrade is to be done

please help
also i would like to say that this gadget is the best
in terms of danger from accidental breakage, mine came with a leather cover fortified with some plastic or metal sheet

. now i m sure to go a long way with it.
