Help please! I have this phone, the Neffos C5s, with the SOC MTK6735 and Android 7.0, but I can't make the ADB command line work. I already installed all the drivers on my OS (W7 x64), ADB and the phone MTP are recognized by my PC, but when I try to list the devices connected to ADB ( adb devices ), the list is empty and in the phone the RSA key doesn't appear. I tried to restart the ADB server, turning off and on the debugging option on Settings, deleting the old permissons of debugging, but it just don't work, and while I try to use ADB with my personal phone it is recognized with any problem.

  • Can you connect the device, go to the "Device Manager" on Windows, find your phone from the device list, right click and check the Properties? Do you see any errors there? – Supersonic Dec 27 '18 at 5:18
  • If the problem is with RSA authentication, you should at least see unauthorized device with adb devices. If the device doesn't show at all, that's something related to connection as @Supersonic mentioned. Check your cable, drivers, USB port etc. Is your phone rooted? If so, you can see if adbd is running or not on your phone. – Irfan Latif Dec 27 '18 at 7:14
