How to backup Kaiboer K620 HD Media player?
Kaiboer K620 is a Venus Linux embedded HD media player. Kaiboer provides "Install.img" to update the system.
I would like to know how to backup the existing system before installing the new "install.img". As I found out something was no longer in the system after I updated the system and even loading supposed to be the original version of "install.img" when it left the factory.
As I found this is Version of 2.6.34 of Venus Linux, and it is also using "squashfs". It has a Realtek 1186.
Thanks in advance!
