Thermos4940 This allows Android Flash Tool to connect and the process actually starts. But, as soon as the device reboots it loses the connection.
I also ran into this issue on Fedora. It seems that the Flash tool being able to work with the phone after it reboots into the bootloader is equivalent to fastboot devices
working without sudo
, which it doesn't by default.
Various places around the web point to 'udev rules' to fix similar issues. Fedora's android-tools
package includes a set of udev rules in a doc folder, which you can symlink to /etc/udev/rules.d
to make them take effect, but these rules only work for adb, they don't change anything for fastboot!
I followed these instructions to create a different kind of udev rule manually, plus a bit from this forum post to create a plugdev
group and add my user to it. After rebooting my laptop, fastboot devices
and the web flashing tool both worked.
