ADB Disconnects when phone is in bootloader

[asadabbas95]

So I'm trying to install TWRP through ADB, but every time i reboot my phone into bootloader, adb disconnects and my computer does not recognize it. This problem only recently started. I am on the official version of Nougat. Does anyone else have this problem and know a solution? Thanks!

ADB is only supposed to work while the phone is loaded into the OS or in sideload mode. In bootloader mode, only fastboot will work.

So the correct command to flash the recovery would be:

fastboot flash recovery recovery-name.img

Example:

fastboot flash recovery twrp-3.0.2-1-angler.img

sorry my mistake, I meant fastboot. The problem I'm having is that i cannot even enter these commands. It disconnects as soon as it goes into bootloader mode.

Uninstall and then reinstall the drivers by connecting the device. Also, try switching ports.

as weird as it may be, try changing the cable also

I was getting fastboot errors when flashing recovery few days ago, and just by curiosity,I tried with another cable.. it worked with no errors

one more thing.. if you send an adb command to reboot in bootloader, then you have to physically unplug your phone from the computer and plug it back again
only after that, fastboot devices command will show your phone in fastboot mode

I tried all of this but it still doesn't work. It was working just a few weeks back when i installed nougat, but now it doesn't work. It's so strange. Any other suggestions?

Does charging work fine? And did you try using a different computer? Try charging the phone with that cord that you're using. (even though it's really short, see if it charges steadily)

Try updating adb drivers. and make sure you're using data transfer cable, there are many charging cables out there.. those will not read your phone in transfer mode, I've faced this, solved by purchasing new data cable.
