Troubles making ADB work on Neffos C5s - General Questions and Answers

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.

I can access my device's storage but it doesn't connect via adb.
Tried rebooting device, rebooting PC, change USB port and cable, uninstalling and reinstalling of adb drivers using several different
downloads. Tried right clicking the ADB interface icon listed under "Other Devices" and installing driver manually but when i need to pick a device
i don't have the "Android Device" Option-
Thanks in advance for any help !

Thanks, I solved this by choosing the option "show all devices" and then choosing samsung under manufacturer and choosing adb inteface.

Solution
Write this email to [email protected] and ask for OS. They will send this zip file "LEAGOO_T5_OS2.1_E_20181025". Open it, and download the MTK USB Drivers.
Than restart your computer. Open SP Flash Tool. Set up Flash tool as you need( needrom.com/download/os2-1_e_20180116/).
Then connect your phone to the PC (Make sure that your phone is off) and press download.
When it´s over, the OK icon will opens. Then you can disconnect phone. After that just turn on phone.
I have made it and it works. Just try it.

Can't connect phone to PC

Hey all, OnePlus 8 not detected in Ubuntu or Gallium OS, not detected by lsusb even though MTP is on, ADB and Fastboot don't detect the device and the device will not let me choose anything other than data transfer, everything else is all grayed out. I have tried re-installing adb, fastboot, drivers, wiping the device, using a different cable (I have 5 I'm playing with) and using a different device. Nothing is working. My phone is on EvolutionX ROM.
Also, the notification that shows whenever the device is connected to another and allows you to change the USB state (MTP, PTP, etc) does not show.
