Unlike previous generations, Samsung is shipping Galaxy S10 smartphones with locked bootloaders which disallows any system modification. However, there is still a way to unlock it and we have listed it ahead. Fortunately, new Galaxy S10 phones don’t need a computer utility to unlock rather it is just a tedious process which needs to be followed. Our guide is designed to work with all 2019 S series phones: Galaxy S10, Galaxy S10 Plus and Galaxy S10e.
Enthusiasts mostly went with Samsung phones due to the fact that they shipped with unlocked bootloaders right out of the box. This is also why we saw so much third-party ROM and mod development for previous Samsung phones. However, new smartphones have changed that narrative. Now, users must go through the unlock process. Despite this hurdle, developers are still eagerly developing for the Galaxy S10. Plus, a locked bootloader is something all other phones already had.

Backup and Other Important Tips
Done with the USB drivers? Perfect. The tutorial is on the next page, but first, please take a look at the following tips and important points you need to take care of. These are important, as we don’t want anyone losing their personal data or apps.
Always backup your important data that you might need after you install a new custom ROM, an official software update or anything else. Make a backup for just in case, you never know when anything might go wrong. Read: How to Backup Android Apps, Text Messages, WhatsApp, Call History.
If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up. [Tutorial: How to Backup Android Phone using TWRP]
A few more optional tips that you should remember:
1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Android Oreo, Pie smartphones.
2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?
4. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend not to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model.
5. [IMPORTANT] Copy all the backup files from your SD card to your computer as internal memory will be wiped clean while unlocking the bootloader.
If you are a developer and would want to unlock the bootloader, we recommend doing that before you set up the Google Play Store, install apps or anything because the security feature in Android clears out everything from your phone when unlocking bootloader of a phone.
Now, let’s proceed with the tutorial below to unlock Samsung Galaxy S10 bootloader.
