I am able to list my Redmi Note from cmd via fastboot devices on Windows 10.

But I want to flash the latest TWRP on my old HTC One XL. I am able to get it recognised by adb devices. Then I can to to fastboot via adb reboot bootloader. But then fastboot devices returns nothing.

Windows complains that USB device was not recognised

I do have the latest platform-tools

enter image description here

I did install the latest HTC Sync Manager. HTC One XL is not listed there as supported though.

Q1) Any idea how to make fastboot work?

Q2) or even better how to flash the latest TWRP to HTC One XL? I got TWRP already there

  • Pretty sure you don't have the proper drivers yet - I remembered it isn't called "Sync Manager".

  • In bootloader, is the device showing Fastboot USB ?

    Why are you going through all this trouble? Through your installed TWRP you can simply flash your new TWRP image. Example: android.stackexchange.com/a/139674/96277

  • @esQmo, yes I can see fastboot usb. I have to scroll down with volume button to have fastboot changed to fastboot usb though

  • So the drivers are installed and you can fastboot. Windows is showing this error probably your USB cable bor connector is damaged

Since you already have a version of TWRP flashed and working, you can use it to flash your new recovery image without the aid of a PC.

Boot into TWRP, select Install and follow the screenshots for the rest.

If you know where the recovery partition corresponds to under /dev, you can also use TWRP's command-line feature.

  • TWRP 2.x doesn't have image installation capabilities, from what I remember.

    Just throwing in some personal experience, maybe I remembered wrong about the exact version number (maybe 2.7?), but image capabilities is added somewhat recently. Whatever works, have an upvote.
