fire 14 Posted September 22 Share Posted September 22 I got a problem with fastboot. From my PC with adb no problem, but after I did the command : adb reboot fastboot (or adb reboot bootlaoder), the phone reboot in fastboot mode but second after, got a logo screen and it says Press any key to shudown. The command fastboot devices return nothing. I tried many different USB cables, different port on my PC, but nothing works. I'm running Linux (Ubuntu 24.04), so what can I do now that I'm not tried before ? Thanks. Quote Link to post Share on other sites
EskeRahn 5,590 Posted September 23 Share Posted September 23 Strange as it may sound, the connection of fastboot is more picky than adb. Usually an older pc, a usb hub or a Linux OS seems to fix it. I primarily see the issues with Windows pc with an USB3 port. I got the issue on mine too, but even a USB3 port on a thunderbolt docking works. As an old tech guy it oozes of handshaking issues, that is a bug in the driver for Windows means it can not correctly handle if things goes too fast, and an usb2 port or a hub is enough overhead for handshaking to work... 1 Quote Link to post Share on other sites
Name_not_avail 69 Posted 12 hours ago Share Posted 12 hours ago I just dealt with this issue on a new Windows 11 PC, mentioned in the LOS 23 thread. Same symptoms as the OP here, trying to use fastboot. If you look at the devices attached to the PC once the phone is connected to it in fastboot mode, I expect you would see a driver error on the PC. The solution for me was to install a dedicated Andriod phone fastboot interface driver in the PC operating system. I can't advise how to do that with Linux, but I'm sure the OP can figure it out.
