Procedure to launch the "emergency donwload" ( tested on V7 native versión) ( not work with bootloader 4992)
Press and hold the Vol +, Vol - (Those of the steering wheel radio control) and the ON button on the rlink screen.
The R-link starts the restart process,
press and hod the Vol +, Vol - buttons (approximately 15 -20 seconds from when the rlink restart starts)
until it on the screen appears: EMERGENCY DONWLOAD and a little further down a progress bar.
Now you can inserta usb with a valid firmware for your R-link.
The system seems to be doing nothing but if you have a USB with LED, you will see that the r-link is reading the file in the USB. (2 minutes approx)
During this time, the screen can turn on and off several times (it is normal)
If the file is correct, on EMERGENCY DOWNLOAD it will appear: 4M
the screen will turn off a little longer and the message will appear: updating system do not disconnect or remove the usb and a progress bar will advance.
The system will reboot with the system restored.
You may have to activate the screen with the ddt4all
