Do you still see this issue with Android 11 or Android 12 releases?

Yes and we are working on that.

You can use Magisk to root the device. https://github.com/topjohnwu/Magisk

Here are the commands to download the source tree. $ repo init -u https://github.com/TinkerBoard-Android/manifest.git -b android12-rockchip -m tinker_board-android12-0.0.3.xml $ repo sync https://github.com/TinkerBoard-Android/rockchip-android-manifest/blob/main/README.md

How about you remove the power source and power it on again? Can it boot successfully then?

可以提供一下BlueOS的網頁或相關資訊嗎？謝謝！

You can also use Linux dd command to do this.

Generally, you can use tool such as balenaEtcher to clone the SD card from a 32 GB one to a 64 GB one. Then, you need to resize the rootfs partition to fill the rest of the 32G space.

It is included in the release (the file ASUS_Android_USB_drivers_for_Windows_20160628.zip is under the folder tools) and you can download it from the support site.

Not quite sure the full version you mean. However, V3.0.2 is based on the Mendel 5.0 Eagle release and V3.0.7 is based on the Mendel 5.2 Eagle release. I would say V3.0.7 is an upgraded version.

Which board do you use? Tinker Board (S) or Tinker Board (S) R2.0?

Thank you for reporting this. We will look into this.

Basically, when the power is cut off unexpectedly, data might be corrupted or lost. This might or might not lead to Android cannot boot up correctly. In this case, Android will try to recover or fix the corruption and make the device boot correctly. However, if the recovery/fixing does not take effect and the device can not boot up correctly, Android still has another mechanism to provide you an option to recover the device manually. https://source.android.com/devices/tech/debug/rescue-party

Since I am not sure what software version is installed on your Tinker Edge R device right now, could you flash Tinker_Edge_R-Debian-Buster-v2.0.5-20220217.zip to a SD card via tool such as balenaEtcher, then use the SD card to boot the device up first? Once it is confirmed that the device can boot up using SD card correctly, please connect type C USB cable to PC and boot up the device using SD card again. For this time, the deice will boot into UMS mode and you can see "Tinker Edge R" logo on the HDMI display. At this moment, you will have a USB drive detected on the PC. Then, you can use balenaEtcher again to flash Tinker_Edge_R-Debian-Buster-v2.0.5-20220217.zip to that USB drive (eMMC on the device). Once it is done, remove SD card and USB cable, then you should be able to boot up the device from eMMC correctly. Let me know if you have any questions. Leslie
