Roadstar RD9200U - sec_smdkv210 - Can't backup current OS image



Hi,

I am software developer. I have a Roadstar RD9200U car stereo and i want to modify os, apps or develop new apps. I rooted device with z4root but before starting i want to backup currently running os. If i make mistake i want to restore original os. CWM and TWRP are not supported this device and i can't backup current os. How can i get os image and restore? Below is my device info.

There is not a usb connector for PC but two usb hosts. I can connect with adb over wifi. If i push eject and power button while power off i think the device is searching image from sdcard and then power off. ADB backup command is not working it says that "closed".

Thanks,
