Hello everyone, I actually have the original Hanvon N520, and have been having problems with it. This is by far the most resourceful site on the net so I thought posting here could get some help.. I've had this Ebook for about 3 weeks (with the Elonex update installed and working) before I had trouble booting it up by the power button. I have to press and hold the reset button on the back to turn it on every single time since then. Sent back for service and they just gave me a new device. Installed the update again and the same problem is happening, again. Needless to say this is very frustrating... I have to install the update in order for the device to mount on my Mac. And it is impossible to un-install the update once you installed it. Have tried formatting the SD card and replacing files again..I really enjoy this Ebook and would just like its basic functions to work! Not sure what to do, any help would be GREATLY appreciated!
