I cherched for a solution and some people told me that adb is a good one. To resolute the problem i need to send a rom from PC to internal SD Card. So, i tried the push function and i got permission denied, i cherched over the forum i found that i need to activate the USB debugging in the phone (i can't do it because the ROM 'im using has a bug), run as Root (it told me that adbd can't run as root in builds production) and give permissions with "su" function (i got a text saying the permission is denied). Then i cherched again and i found that i need to run adb in recovery mode, but my Samsung Galaxy Pocket Duos GT-s5302 is listed on device only in boot mode.
Can anyone give me a solution please ?
