I have a Chinese tablet Genesis GT 7320 Androd 4.1.2. It is rooted using kingo. I changed the vold.fstab file on the / etc partition system to vold.fstab.bkp. The table was locked and did not start anymore. Action or recovery mode by pressing the power and volume buttons above. I have access installed on the macbook and access to the tablet through the adb shell. After running commands with busybox. I'm a layman and I took time to discover the adb and busybox commands. However, I can't access a / etc partition system to rename the vold.fstab.bkp file to simply vold.fstab. I saw on the internet that you need to mount a system partition. I tried several commands I found on the internet, but I didn't get results. Below are some of the directories I have access with adb shell. Can someone help me?
