Support for RKNanoB #95

Hi, I found my old 2012 MP4 powered by RKNanoB. I successfully compiled rkdeveloptool in linux, put the device on maskrom mode throw "Firmware update" option from the device settings and when I run this ./rkdeveloptool ld

I got this: DevNo=1 Vid=0x71b,Pid=0x3226,LocationID=201 Maskrom

But when I try any other command, always get the same error.

./rkdeveloptool rcb
Read capability quit, creating comm object failed!
./rkdeveloptool rid
Read Flash ID quit, creating comm object failed!
./rkdeveloptool rci
Read Chip Info quit, creating comm object failed!

Same happends with ppt, rl, td and rd. I want to dump the firmware from it to change some background images and rewrite (if possible) some functionalities of the device.

Thanks.

Hi!

It's been a while but it might be useful to someone. You need to run it with sudo, it needs access to low level usb stuff.
