[Q] Connection with PC

Hellow. I have some problem with connection of my One. Atm i wanna s-off my phone.But can't.
After connecting phone to usb2.0 port win8 recognise it well (checked by "adb devices -l"). But when i try to reboot into bootloader i've got "waiting for device" (fastboot reboot bootloader). Ok i'm switch off the phone and boot in bootloader (fastboot mode). Phisical connection is good (fastboot usb). Try to check connection by "adb devices -l" and i got no one device connected. But in same time i can easy flash recovery by "fastboot flash recovery recovery.img". Btw when i put phone in fastboot mode my win8 told me that connected device not recognised and can't work good, but when i start android win8 got my phone well. I've check it with two original htc usb cables and one not original.
Any ideas?
Thx!
When the phone is in fastboot mode, you use the fastboot command, adb won't work. When the phone is not in fastboot mode, you use the adb command, fastboot won't work.

"waiting for devices" in ADB While trying to install TWRP?

Updated today to OB14. Now trying to re-flash twrp. Type "adb devices" and it showes connected to my OP3T. Go to flash the twrp file and says "waiting on devices"??? Why won't it flash? (using cmd fastboot flash recovery <file. Img> Yes, I'm in fastboot mode. Do I need to reinstall abd drivers?

Something is not quite right. adb and fastboot have different requirements, and will never work at the same time.
adb = works in OS or TWRP, will not work in fastboot mode. Debugging must also be enabled
fastboot = only works in fastboot mode. Debugging enabled not needed.
So adb working, and fastboot not working is expected, but to me, means you are not in fastboot mode. Or your are changing modes/states between commands (which is really confusing).
Go into fastboot mode and type: fastboot devices
And see if it returns the phone ID.

oneplus 3t android 7.1.1 OS 4.5.1 unlock bootloader

Hi Guys
I am unable to unlock my bootloader. I have downloaded adb and fastboot drivers. I connect device. run adb devices, device details are displayed. i then run command to reboot into the bootloader. it reboots into the bootloader. when i run fastboot unlock oem nothing happens.
I have enabled the developer options, USB debug, OEM unlock, Advanced reboot
is there something I am not doing right?
adb is working in your system but fastboot is not working.
Check your drivers properly, they are not installed properly.
search for how to install adb and fastboot drivers on windows. There is no problem in windows xp but in windows 10 as in my case, you need to activate the developer option in setting and manually install the drivers. Go to device manager and check if your device is showing as android device when you go to fastboot mode.

Did you type fastboot devices?
It should show you that your phone is connected.
Then you can run the unlock command.

Brother I can't unlock bootloader that's why I am having issues. Can you please help to unlock bootloader?

Question [Resolved] No connection with pc in fastboot mode.

Hello all, I'm trying to install a new ROM but one of the first steps consists in getting access to adb and fastboot mode.
Unfortunately, I can easily access to adb mode, and adb commands respond well, but when I then go in fastbood mode 'adb reboot fastboot", My phone goes to fastboot with the icon on the screen, but won't answer to any fastboot commands.
I've tried to install adb drivers, uninstall/reinstall the drivers (but it's always the windows drivers that installs first). I even tried to install google usb drivers using SDK manager, but didn't succeed this step.
I've tried to change the usb cable, but with another one, it was worse: even the adb commands would not work. So I guess the one I'm using is ok.
I'd be very happy if someone could help me fixing this frustrating bug!

The first step is to unlock the bootloader.

For fastboot try:
adb devices
........... (here you must see a number)
adb reboot bootloader
fastboot devices
........... (here you must see that number again)
Hi, thanks for trying to help me:
you're right , first is the unlock, but it's done. it's even in "grey" on the screen and written: bootloader is already unlocked. I've tested my phone with "root checker" and test is ok.
you're right about the command, this is the one I've used to go to fastmode and actually this command works: as I said, when in adb mode, it's all good: my phone is connected to pc and accepts the adb commands. But once I switch to fastboot, this is when it's going wrong: my phone's not answering to any commands.
To be more precise: when prompting: adb devices: i get a number. When prompting, in fastbood mode, fastboot devices: i get nothing.
Alleluia!!
Finally found out how to fix it!
After going in fasboot mode with the command: adb reboot bootloader, i opened the windows device manager: There I found a android XXx interface, or something like this: anyway, something barely identified by windows. Right clik, update drivers, manually update, pointing to the folder I store the google usb drivers and : Bingo! It works like a treat.
I now can step further in the process... Hope I won't need to come back with another question in the next minutes!
