  With the development cycle for Ubuntu 26.10 officially underway, Canonical has published stonking/snapshot-1 . For early adopters, developers, and enthusiasts looking to ride the absolute edge of the open-source wave, the temptation to jump from the stable shores of 26.04 LTS, Resolute Raccoon, into the development stream is strong.

Disclaimer: Unlocking the bootloader may lead to data loss, security risks, and void the warranty. Proceed at your own risk and ensure you understand the consequences before attempting the procedure.



Backup Your Data

Before initiating the process, back up all your important data, including contacts, photos, videos, and files. Unlocking the bootloader will wipe your device, so ensure you have a copy of your data stored safely.

Charge Your Device

Make sure your Samsung device has sufficient battery life or connect it to a power source during the process to prevent any interruptions.

Enable USB debugging

Go to Settings > About Phone > Software Information. Tap on the "Build Number" seven times to enable Developer Options. Then, navigate to Developer Options and enable USB Debugging.




Install ADB and Fastboot Drivers

- Download the Android SDK Platform Tools (ADB and Fastboot) and the Samsung USB driver on your computer.

- Extract the platform tools zip file to a folder on your PC and install the USB driver 
- Open the command prompt or terminal window on your computer in the platform tools folder. 


Enable OEM Unlocking

- Go to Settings > Developer Options.
- Scroll down and find "OEM unlocking."
- Toggle the switch to enable it.
- Confirm your screen lock password or PIN if prompted.

Reboot to Download Mode


Method 1:

If you don't reboot using the power menu, hold power and tell bixby "reboot to download mode" bixby will say "are you sure?" reply with "yes" 


Method 2: 

Open a command prompt

cd "path to the platform tools folder"

adb reboot download 


Hold volume up and volume down at the same time and plug the phone into your PC

Long press volume up to unlock the bootloader




- A warning message will appear on your device.
- Use the volume keys to navigate to "Yes" and confirm the bootloader unlocking by pressing the power button.
- Wait for the process to complete. Your device will be wiped during this step 

When the phone reboots, connect your phone to wifi and enable developer options to bypass the vaultkeeper service
