Root Android 11 on Tinkers Board R2 S

[AJofre 0]

Trying to root Android 11 on Tinker Board:

We download the .img file (v1.0.6-20221003) from the following source: https://tinker-board.asus.com/download-list.html?product=tinker-board-s-r2

We extract the boot.img from the downloaded file and patch it with Magisk. 

At this point we couldn't able to reboot in fastboot mode, device gets stuck on the logo screen.

For enter on fastboot we tried: "adb reboot bootloader" , "adb reboot recovery" and then select bootloader, adb shell and then reboot bootloader. But same result.

Replying to this old thread because I had the same problem this week on the Tinker Board (not S) R2.0:

I tried both of the Android 11 images with the same issue as @AJofre - after running adb reboot-bootloader the logo screen appears but the device gets stuck on that screen and the device is not visible when I run fastboot devices

• Tinker Board R2.0 /Tinker Board S R2.0 Android 11 V1.0.6
• Tinker Board S R2.0 Android 11 V1.0.0

However, I was able to work around the problem as follows:

1. Reboot the device to boot normally (I had to power off the Tinker Board, remove the SD card, power it on again, power off, reinsert SD card, power on again)
2. adb shell
3. su
4. dd if=/storage/emulated/0/Download/magisk_patched-XXX.img of=/dev/block/by-name/boot
5. adb reboot

After the reboot, I'm able to grant root permissions to apps that request them.
