E8709 Error on CDJ 850 while updating firmware
I just got a set of CDJ-850s that were purchased a couple of years ago, but used for a little and then never touched again. These are in perfect condition and I used them with USBs for about a week, everything was working perfectly.
I wanted to use these with Traktor, so downloaded all the software/drivers for the decks, and also updated the firmware to the latest version (1.12). When updating, it is meant to show DOWNLOADING - old versions number => new version number.
Where its suppose to show the new version number 1.12, it was blank - but still completed the firmware. I think I used the wrong type of USB (It wasnt MS-FAT) while updating.
Now when I turn on the decks, they go straight to E-8709 message, and I am unable to work with them.
Is there anything I can do to reset the devices, as clearly something has gone wrong when updating the firmware??? I did it step by step as per the manual, so am very upset that this has caused my decks to crash, expect I forgot the put the USB as a MS-FAT and I think that’s where it messed up. Now when I try to upgrade the firmware again using Reloop+USB, it won’t even come up.
I’m extremely upset as I had just bought this and in my country (Brasil) it is extremely expensive for anything related to electronics. I'm shocked that the best answer Pioneer has is take it to a specialist for something like this? How is there no way to reupdate the system?
Accedi per aggiungere un commento.
Try the firmware update again with a FAT32 formatted drive.
but when i press the usb + reloop at start up nothing happens. It won't let me update firmware anymore. Is there anyway of doing with USB ---> computer? Like a full reset on the software?
I encountered this same problem and have not been able to find a solution in the forums. After researching, I found out that this can be solved simply be resetting the CDJ to factory setting: (Press these buttons simultaneously: USB, Back and Power button). Done. I don't know why even the pioneer people cannot suggest this.
Because it doesn't always fix the problem.
Great reply, Pioneer. So updating the firmware with a FAT32 formatted drive ALWAYS fixes the problem? You suggested that.
No, but we use a "start here and work up" type troubleshooting.
If your computer freezes during use do you format it and reinstall the operating system?
