before i did the J-tag the box stopped giving any display just the green light,i took the box to a tech guy and i was told by him that the problem is the flash chip,when he told me how much it would cost to repair,i decided to do a j-tag myself the j-tag software said corrupt boot loader in the dos window so i searched for a good bootloader i found one for dm500 clone and the j-tag was successful.now i have uploaded EDG image but i am still having the same problem,will go back to the tech guy today because now i have display on my box lets see what he says.
