-  - Download [[https://batocera.org/boards_requirements/odin2_custom_abl.zip|odin2_custom_abl.zip]] (this is the same package as the Odin2 above) and extract it into **/sdcard/odin2_custom_abl/**. It is really important that you extract the zip file in this directory, because some paths are hardcoded in the next step. If you extract it somewhere else, the flash will fail, but you won't necessarily notice it. If you extract somewhere else, you will have to adapt the paths in the following script.
+  - Download [[https://batocera.org/boards_requirements/SM8550-ABL.zip|SM8550-ABL.zip]] and extract it to an sdcard.

+  - Using the file manager (Files) copy the files off your sdcard onto the Android file system into a directory called **odin2_custom_abl** (this directory name is important).
-  - Then, if you have your Batocera micro SDCard inserted in your Thor, boot it up and it starts on Batocera. Remove the SDCard, and you'll be back to Android.
+  - To ensure you're using the correct location to create the **odin2_custom_abl** directory. In the File app, hit the hamburger symbol on the top right (three lines) and then choose your device (i.e. AYN Thor)
+  - Go to Android settings, at the bottom in the **Odin2 or Thor settings** -> **Run script as Root** and select the **backup_and_flash.sh** script from the directory called **odin2_custom_abl**.
+  - The script will run quickly and back up the original boot loader to **/sdcard/backup/** directory.
+  - Keep this as a backup in case you want to rollback.
+  - Download the Batocera SM8550 image and burn it on an micro SDCard. **Warning:** make sure you have a high quality SDcard. In my testings, I failed booting a 256GB no-name card, while a 128GB PNY went flawlessly.
+  - Then, if you have your Batocera micro SDCard inserted in your SM8550 device, boot it up and it starts on Batocera.

+  - Then navigate to 'Set device model'. There you must choose your device from the list (if you don't do it, your machine might not boot). Then navigate to 'START' and press power to boot.
+  - If you want to go back to Android, remove the SDCard, enter the boot loader menu by pressing ''[vol +]'' and ''[power]'' and switch the boot selection from Linux to Android. and you'll be back to Android.
 ==== Troubleshooting ===
-Before you flash with the new boot loader, you can access some boot options by keeping pressed the **[Vol -]** and **Power** buttons. The old boot loader is in portrait mode and looks like this:

-If you still have access to this menu after you think you flashed your boot loader, try again (and verify the paths, the install needs to be in the directory specified above).
+You can switch from Android to Linux booting from this menu.
-After you successfully flashed the new boot loader, there is no need to use any key combination to boot Linux and Batocera. If, for whatever reason, the Linux boot process fails, you will have this kind of message on your device (in landscape mode now). After a few seconds, it will automatically boot back on Android.
