Hello! I became the proud owner of your device RQ0253! use for 2 months! everything worked wonderfully until today! the device is switched off and no longer included! with power everything is fine ... there is a faint hissing sound from the device ... may the virus do not know ... tell me how you can recover if I have not even the logo come from?

Hi .. I have no DVD drive .. I looked at various forums, and I realized that I have a problem with the MCU .. how to change the firmware if the device does not turn on .. all videos on your site do not provide information on the insertion device, which is not included. ... as soon as I connect the device to the computer via usb it starts beeping loud even without the 12 volt power supply

Hi, sorry for my mistake about the DVD drive.
After discussing your issue with our technician, your unit display screen may have problem.
Please tell us your order number or buyer ID.
Or you can send email to our customer service "support@autopumpkin.com".
We can arrange to send you a new display screen and you can try to replace it to solve the problem.
Hope you can understand.
Regards

I inserted a memory card with the songs. And it was probably bin files. because in the MCU settings update when I pressed the auto search, he found the file and start the update! before all input methods in recovery mode is very easy. I have a black screen! And there is a faint squeak of the State .. similar to the hard disk boot ... it all happened because of the bin file to update the MCU. I updated so that the logo is not even there! How do I restore even the old MCU or install a new device to not include!
