In this guide, we will show you the steps to enable the FastbootD Mode in Samsung recovery. When it comes to custom development, then Samsung has always taken a different route. Whether it’s their firmware [AL, BP, CP, CSC] or their flashing stuff [using Odin instead of Fastboot Commands and using the Download Mode for flashing instead of Bootloader Mode], things are completely different in this ecosystem.
Along the same lines, flashing a Generic System Image is somewhat different for Samsung devices. This is because these GSI ROMs are flashed in the FastbootD Mode which is absent from most Samsung recoveries. Fortunately, there does exist a nifty workaround using which you can enable this mode on your device. And in this guide, we will show you how to do just that. Follow along.
How to Enable FastbootD Mode in Samsung Recovery
Before starting, please back up all the data on your device. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.
- Set up Git and authentication with GitHub.com from Git using the instructions given here.
- Then navigate to the Johx22/Patch-Recovery repository and click Fork at the top right.
- Under “Owner,” select the dropdown menu and click an owner for the forked repository.
- Optionally, to further distinguish your fork, in the “Repository name” field, type a name.
- Optionally, in the “Description” field, type a description of your fork.
- Optionally, select Copy the DEFAULT branch only.
- Finally, click Create Fork.
- Now extract the recovery.img.lz4 and upload the recovery.img (not lz4) to transfer.sh.
- NOTE: Other file hosting services, like Google Drive, are causing issues with this service. So use transfer.sh for now only.
- Once uploaded right click on the Download button and copy the URL.
- Head over to the Actions tab and click on RECOVERY -> Run workflow.
- Insert the copied URL in the RECOVERY URL field and Start the workflow.
- The patching will now start. A Patched-Recovery.zip will be uploaded at the end of the process.
- Download it and extract your patched recovery image.
- The Image will already also be repacked to .tar for flashing directly through Odin.
- Once flashed, you can now directly access the FastbootD Mode via:
- From the OS: adb reboot fastboot
- From Fastboot Mode: fastboot reboot fastboot
That’s it. These were the steps to enable FastbootD Mode in Samsung recovery. If you have any queries concerning the aforementioned steps, do let us know in the comments. We will get back to you with a solution as soon as possible.
