We have known that some customers want to fully customize their car stereo. This needs to root the car stereo to achieve. After you root your Android car stereo, you gain access to the entire file system, with full admin rights.

Recently, our partner has found a safe way to root the Android car stereo. Actually, it is not necessary for most customers to root the car stereo. So, before you root your car stereo, please think twice. It's always risky to root, and Pumpkin shall not be blamed for offering free root suggestions.

Jammy,
I want to try to root my head unit (CN03-03101B-01A-DE) in order to get the 4G dongle work.
However, I have following questions before I try it:
a) Is it possible to copy su into different directory? I think GooglePlay refuses to work if it finds a su in system directory. Do you know if this is true?
b) I can't find a "rooting.rc". Where do I get it from? Can you tell me the contents of this file?
c) Why shall I never press update button in SuperSU? What does it do and why does it cause a Bootloop?

Thanks,
stedon81
