Hello All. Im new to this forum. I found it while looking for info and firmware for my Maylong 250. It stopped charging last week. I thought it was dead until I tried starting it while pluged in. It only works when pluged in. I found a second 250 on ebay thathas a bad screen so I bought it and changed the screen from mine to the second one. But I has issues and I'd like to reload it. I tried to do factory reset, but it askes for a password. I also nowwould like to get the firmware for it. any help would be great
