I have an EZ-Flash Vi, H805, K3.0 OB1, standard firmware as I have not been able to do it yet. When starting up my EZ-Flash, it just gives a black screen. I have everything necessary on it, so what am I doing wrong? My regular SD cards do work. SDHC is a SanDisk Mobile microSDHC Card, 4GB. It says that it is made for mobile phones, but the back says that it is made for microSDHC devices. If you need the exact type, please tell me where on the package (or card) I can find it.
