ADB doesn't work

When I plug in my phone to my PC the only thing that happens is it begins charging. Doesn't show signs of adb working, only thing that happens beside charging is my pc says it's an Unknown Device.
I tried all sorts of things, like USB Debugging on and off, MTP on and off, PTP on and off, I think even fastboot doesn't work. I tried to install all kinds of drivers (official, unofficial, uninstalling them afterwards if they didn't work ofc), I tried Wug's toolkit, nothing. I tried killing adb server then restarting it - nope. I even tried all of my USB ports, both 2.0 and 3.0. Also tried 3 different roms/kernels (L dev preview, Purity and Mahdi), didn't work aswell.
Things seem pretty hopeless at this point :/

Download wugfresh toolkit... look In the section of driver installation... They'll help you out

driver installation...

As I said, I already tried the driver thing in Wug's Toolkit. Also my Windows allows unsigned drivers.

Bump :/

If it still says Unknown Device on your PC, its a driver issue. Personally I use the Google usb driver, that page also has instructions on how to install the driver. Try uninstalling whatever drivers you have installed right now, then install Google usb driver carefully following instructions. Fastboot needs bootloader mode, so make sure your phone is in that mode before trying a fastboot command. I use the Minimal adb installer to install adb/ fastboot tools.

Fastboot actually works, only ADB doesn't. I use the Android SDK to install adb/fastboot and I tried Google USB drivers and also Universal ADB. I tried the drivers from Wug's Nexus Toolkit and then LG drivers, same old story :/
Edit: I upgraded from Windows 8 to Windows 8.1 using clean install, still same problem.

Might be windows 8/8.1 giving you driver signature grief. Try the Universal adb drivers:

Bricked my 6p and computer wont recognise it

Ok, so i managed to brick my nexus 6p, it will not boot into android, stupid as i am i do not have a backup on the phone, and on top of that, windows does not recognise my device in bootloader mode. Of course i have tried installing USB drivers, but strangely my computer will not even recognise that im plugging in a USB device, i/e it wont even make the USB connected sound.

How did you brick it? What drivers are you using?

I tried to install franco kernel on my chroma rom, and it just wouldn't boot.
Also, I am using the drivers installed by the unified android toolkit.

Do you still have the Chroma zip on your phone? I'm guessing not, but if you do just flash that. You could try uninstalling the drivers that you currently have and installing the drivers from the Android SDK. I have a link to the SDK download page and instructions on how to install it in my guide. Otherwise, do you have access to a Linux machine? No drivers required for Linux, you just need to install the Android SDK and adb and fastboot should work out of the box so to speak. Or if you don't have access to a Linux machine you could even create a bootable Linux usb and do it that way.

I just came back home from buying a new USB cable, and apparently it was just my cable (original 6p cable) that wasnt working... Terribly sorry for wasting your time, i appreciate it though!

Bricked Oneplus 2 Not Connecting To PC

- How My Phone Got Bricked?: (Chinese Version Oneplus 2) I Was On Oxygen OS 3.0 And TWRP 3.0 And I Decided To Flash The Resurrection Remix ROM, I Did A Full Wipe And I Installed The Rom And It Failed To Installed The ROM. Now My Phone Is In A Bootloop With No OS Installed. I Have The Chinese Version OP2
- Current State Of My Device: My Device Is In A Bootloop With No OS Installed, I Did Notice That My Phone Was Not Being Recognized VIA Fastboot & ADB On My PC. I Went Fastboot Mode And My Phone Is Not Being Recognized By PC, And I Went To TWRP, ADB Was Not Working And ADB Sideload Is Not Working. I Also Tried A USB OTG With A USB Drive And Still TWRP Recovery Is Not Recognizing It. How Ever When I Connect My Device To PC And Check Device Manager And Press Scan For Hard Ware Changes My Device Shows Up As "COM 1". I Also Did Try To Put My Phone Into Qualcomm Mode Trying Alot Of Key Combinations But My Phone Is Not Getting Into Qualcomm Mode Or It Just Might Be Me Since I Heard Its Tricky For The Phone To Get Into Qualcomm Mode. I Did Try One Click ADB And Fastboot Installed And Qualcomm USB Driver, Still No Luck. And I Did Try The MEGA Unbrick Guide. I Have Tried This With 3 Other Computers Which Are All Running Windows 10 And Turned Driver Signature Enforcement Off And Still No Luck, And Also A PC Running Linux Mint And Still No Luck. Please Help Me And I Will Put All Thanks On All Of Your Replies And I Really Appreciate Your Help!
- Whats Working:
- My Device Charges From The PC And Wall
- I Am Using The Official OP2 Cable
- Can Access Recovery + Fastboot
- Turns On But In A Bootloop

I think it's a bad cable... if you can get into fastboot and the PC with Windows 10 and Linux both don't see it.. cable

Not sure whats needed on windows, since I never use it....but after a fresh install of Ubuntu 16.04 a few days ago, I did have to install a few adb and fastboot packages before my devices were recognized. Do you know if the adb/fastboot packages and they're dependencies are installed on the Linux mint computer?
If yes, power off phone and plug into computer. Then start phone in fastboot mode. Open a terminal on the PC and run "adb devices" (without quotes of course) .....any output on screen?

Yeah I did try typing ADB devices and Fastboot devices in both twrp and fastboot. I think the issue might be the cable

Yeah I think the cable is probably the problem. Although my phone chargers with the cable. I will look into buying a new cable soon but its a little expensive. I will try to buy it next week

I'm sure you been reading and seen people with the same cable as ours with the same problem.. works with charging but not adb or fastboot. But you can try to issue a command with it.. fastboot devices does sometimes come back empty.. just try to do OEM unlock for example.

My cable did used to work with adb and fastboot before, and I did unlock the bootloader with it before. I think now the cable got broken

Same issue working cable
Same issue... but my cable is working fine. I have a 2nd OP2 and tried the qualcomm connect with my cable and volume up, and worked perfect. More over, I swapped motherboards and still didnt work. I have access to twrp on the phone and I can get into fastboot. But no way to connect to my pc

Oneplus 5 adb sideload not recognize on stock recovery

I have a big problem with the adb driver. It works perfectly to perfection when the phone is accessed both without usb debugging or with, adb devices detect the phone, and even fastboot when booting into the bootloader. The problem is that when I get into adb sideload from the original recovery my pc (windows 10 x64 build 1703) does not detect it, there is no way to make it work. I've tried changing a pc, cable, usb port, but always the same problem. I have installed and tried every type of driver, but there is no way to run it. I think the problem is oneplus5 stock recovery.

Is you're device connected with a USB 3.0/3.1 port maybe ? If so try a USB 2.0 port and install the latest ADB driver

I am also facing same problem...please help me

Does the stock recovery even have adb capabilities?

Pc cant detect fastboot device

Tried miui 12 and after flashing rom the twrp is gone I tried to reflash it the same way I did first but sadly when I'm on fastboot PC can't detect it. also tried it with other softwares but same result. Device is fine and responds when open but not in fastboot mode. Currently running miui 11 .0.6 China stable. Stucked. Also all drivers are updated

Same here.
I accidentally flashed china stable 11.0.4 zip rom on my global device through twrp and upon booting up twrp was gone and when i plug in usb the pc doesn't detect anything. In order to make pc detect the phone via usb cable i have to reboot phone while plugging usb to laptop that way file transfer option shows up in laptop and adb works but fastboot doesn't work i can force boot to fastboot through adb but upon booting to fastboot the pc stucks at waiting for device. All the drivers are installed
Currently on china stable 11.0.6

Same issue indeed
That's exactly what's happening right now. I hope someone can help us

Quote me if u find any luck.

Same issues

That happens me sometimes. I only reboot the device into fastboot again, reboot the computer, and that it. This may change depending on your computer CPU, mine is AMD. And ussually I have to use a 2.0 USB or if it still does not work a USB 2.0 hub. I know the hub thing is strange but it worked for me when my pc does not detect the phone in fastboot. Hope it helps .

With my PC I have to open device manager, look for the device, usually has a yellow sign next to it. Right click on the device name, click update driver, click browse my computer for driver software, click let me pick from a list of available drivers on my computer and pick mtp USB device. Then I read it. I hope this helps.

I use a usb hub that is very old i guess, as it uses MiniUSB. By the way with multiple computer it should work, your error is very strange, I never saw it. A thing that may work is trying to use fastboot on a Linux system (no, with VMs no). So if you can flash a pen drive with a Ubuntu ISO or any linux distro, boot linux,install fastboot and check if it detects your phone.

Read my 1st reply to this op
Even file transfer option doesn't show up if i connect my phone via usb to laptop.
In order to make pc show file transfer option i have to reboot phone while connecting the phone to pc so.
That way i can use adb but as soon as i boot to fastboot via cmd pc doesn't detect the fastboot mode.
Tried with 3 laptops

Issue Fixed

Dude I fixed it and I managed to flash global and maybe reflash EU when miui 12 stable arrive
Try another type c cord preferable the original one. I just change the cord and everything went fine fastboot can now be detected via "fastboot devices".
