Can somebody help me ! I have the Coby 7015a model. I downloaded the update from Coby and I don't know if it was the old update or the new update ! (I did it last week) I completed all the directions from newbie friendly guide for rooting and google market install on windows. I got to the part where the "su" is entered and the $ is suppose to change to #. Didn't happen ! I get the message about superuser, but the symbol is still $. If I type in the flash_image info, it comes back with flash_image: permission denied. I'm very frustrated and this is my first exprience with one of these so I am definitly a "newbie" ! My sister bought this for my 90 year old mom who loves to read but is starting to have trouble seeing. She can read with this but I haven't be able to download any books ! Any advice will be greatly appreciated !
