I am attempting to use fastboot on an old Samsung Galaxy A01. It is a learning exercise for unlocking. Based on this, the device should support using fastboot. I got it off a Samsung forum. I am running on a Windows 11 machine.

I can run

$ .\adb.exe -d devices
List of devices attached
R9HN*******     device

Which allows me to run .\adb.exe reboot bootloader which reboots the device into fastboot. The issue I cannot seem to solve is getting the drivers to work at this point.

I run .\fastboot.exe devices and nothing shows up. I checked my device management and I can see it under Ports (COM & LPT) > USB Serial Device (COM9) I have added the Samsung drivers from here and it will change to those. Each time though, I get a warning triangle on the device and it says.

This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful.

I have also manually attempted to use the Android drivers here but it says they are not the correct arch?

Any suggestion on how to get fastboot drivers for this device to work?

    Note that there are a lot of generated pages out there that are just "click traps" without actually containing valid information about Android rooting. The Samsung devices I had contact did not had to be unlocked via fastboot, usually Samsung devices don't have a real fastboot mode at all. You enable OEM unlock and then flash what you want to flash using Odin/Heimdall. On next reboot the phone then asks if it should be unlocked. The COM9 you get is a good indicator as Windows never detects a fastboot device as a COM device. So you are most likely in DFU mode because there is no fastboot.

  • @Robert just to confirm I can do .\adb.exe reboot bootloader which reboots the device to a screen that says fastboot. Does that not matter and I should look into Odin/Heimdall? I saw those before as well but those looked more like that "click traps".

    I would recommend to search xda-dev forum for your device and root. You will get some topics and the few I have checked they always use Odin/Heimdall.

  • Welcome to the Q&A site Android Enthusiasts Stack Exchange. As mentioned by Robert, Samsung devices don't have Fastboot mode (it's a stub/not working). Instead, they have Download mode, which can only be operated with Odin/Heimdall.
