Hello ! Good morning everybody !! I have tried to make a firmware upgrade to my ETEN P700, but I've loaded only the first part of the software PKHer_217.nbo. Then the phone told me " everything ok , so I switched it off, but now the phone doesn't work anymore. I got only a blank screen or neither that. Could anyone help me ? I'm practical in electronic, so I can make many things, such bridges, new cables, external supply and so on . Please HELLLPPPP !!!!!!
