Man am I the only one having major problems getting this batch tool to load the old firmware ? I have a 64bit windows 8 laptop . I have followed the instructions that says to hold down the volume + and then plug the USB cable into the PC.
It shows a unnamed device and and no driver? When I do this after the failed attempt my player doesn't turn on? I have to remove the battery, and then put it back in and the player turns on. Am I going to have this problem when a new version of the next firmware is released or is it just trying to go back to the original firmware?
After you connect DX90 to pc while holding volume up button, if your prompted to find drivers, direct it to the RockUSB folder in the rkbatchtool file, if not prompted for drivers, You need to go into Device Manager on you PC, find the icon labeled with a question mark, open it up, go to Driver tab, hit update driver, direct to the folder labeled RockUSB from the rkbatchtool file you got and press update. Then you can open the rkbatchtool app, click the bottom left button and select the second option to change language to english, input the directory for the firmware you want to load at the top, then click upgrade at the bottom to start the flash.
