ADB not working but Fastboot is

I recently bought a YU YUPHORIA . When i tried to root it I was stuck at waiting for device. I checked on different forums and somehow everybody was telling about how the ADB drivers are not installed. I tried different methods . I tried to update the Android Composite ADB Interface as they had worked for a lot of other people but they didn't work with my phone. Then i tried to install ADB drivers with the help of Pdanet but the Pdanet was stuck at Trying to install Pdanet on your phone. When i write fastboot commands like fastboot -i 0x2A96 devices my device is recognised. But when i write adb devices my device doesn't show up. Please help because I really need to use this phone for app development purposes but Android Studio is also not recognising my device. I have managed to root my device but can't solve this problem of ADB not detecting my device.
Usb debugging is enabled and i Have tried uninstalling all android drivers . But then the android ADB interface is shown in other drivers with yellow mark and when i try to update it same thing happens "Window unable to install drivers"
Is their any hardware problem with my Device.?

First, be sure you have enabled USB debugging in developer options. Also, you may have to uninstall all android drivers from your PC and then reinstall the specific drivers for your device.

OK, try to update manually. Select update driver, then choose let me pick, then navigate to where you have the new driver.

ADB for GT-I9195

Hello,
I broke my screen and I want to use the androidscreencast in order to recover some data on my Samsung GT-I9195.
I installed ADB version 1.4.2.
When I plug my phone on my computer (win7), the phone is recognized and I can browse its content.
But the command adb devices returns nothing:
"List of devices attached:
"
Edit: I first tried to recover my phone with Kies but the phone is not recognized.
Can somebody help me?
Thanks in advance.
V.

Before I start suggesting soloutions/ideas was USB Debugging enabled through developer options before the screen smashed as if not there's not much you can do via ADB.

Unfortunately, debugging mode is not activated.
Is the activation of debugging mode mandatory for connecting a mobile thanks to adb?

I'm afraid that debugging mode is necessary for an adb connection to the device.

I may probably dream, but is there a chance to activate the debug mode with a broken screen?

CAN'T ACCESS TO ProjectMenu ON MATE 8 EMUI 8

I accidentality flashed a wrong oreo Chinese firmware on my international mate (nxt-L29), with that I'm stuck with booth bootloader and FRP lock ("enable OEM unlock" option in developer mode sitting is greyed).
in attempt to resolve this problem I'm asked to put USB ports setting on Manufacture mode in ProjectMenu witch i can't access via *#*#2846579#*#* code on phone.
it shows nothing.
help please....
is there any other method to enable Manufacture mode in usb setting like adb command ?????

note:
when i was in the upgrade mode (phone off, press the tow volume button up and down then connect the micro usb cable) i noticed the device respond to ADB commands and it's detected but unauthorized.
is there a way to make adb works.

you need to activate usb debugging first in the setting then it will give authorized

ADB fastboot can't detect the phone

I'm already experienced in custom ROMs and root... However this time the adb tools can't detect my phone even if it's attached by the original cable, and also the drivers are installed correctly + i allowed the USB debugging.
Any suggestions?
Or Sdk platform tools alternatives
Btw i want to reinstall a custom recovery for the phone.

Does phone connect in MTP mode?

No

My guess is you havent't installed the "Android USB Driver" suitable to your phone.
BTW: ADB Tools? I've never heard / read of them.

No ABD devices found Samsung A9 2018 SM-A920F

I rooted my Samsung A9 2018 SM-A920F, but now i have problems with smalipatcher to mock gps. I installed Java, but an error occurs. NO ABD devices found. I tried it with platform tools, in device manager i tried to update drivers, but keeps saying best drivers are installed, but the phone is still not recognised. OEM debug and OEM unlock is on, tried to revoke oem debug as well, but smalipatcher still cant find phone. Tried different cables as well. Someone that can help me?

Add Samsung A9 2018 SM-A920F to this thread's title thus mainly owners of such device get addressed.

Nothing. Gives no number. I rebooted my usb drivers as well. When I connect the usb and check device manager it adds Samsung Android Phone en when i open it gives Samsung Android ADB interface. My phone does not pop up as Samsung A9 but as MTP-USB-device

You have to switch phone's USB mode to ADB.

OEM unlocking and USB debugging are on, I put default usb configuration on Transferring files. Is that what you Megan? How do I put it on ADB?

Your phone is configured to connect to phone via USB in Media Transfer Protocol (MTP) mode what is for transfering files.
As already said you have to configure phone that it connects via USB in Android Debug Bridge (ADB) mode.
IDK how you can achieve this because I don't have a phone as yours.
Follow my advice given in post #2

Thanks, My device is not found in platform tools using the adb devices command, but it's on OEM unlock and USB Debugging is on. I added the phone in the tiltle, hope someone had an solution for my problem. Don't understand why it's not working. When I connect phone without the USB debugging it get's recognised, but with debugging mode on, nothing to find

Enabling OEM Unlock and/or USB Debugging simply sets an allowance flag, nothing else. It doesn't configure phone's USB mode.

I tried it on the laptop from work and there the phone is recognized in adb. But sadly I don't have administrator rights on that laptop to open Smalipatcher. Is there an alternative or work around available?
