How to restore the boot loader in SenseCAP K1100

I received the K1100 and played around with the Wio terminal tutorial as it was displaying the LORA screen setting. Now when I slide the power switch and release as instructed to enter the boot loader mode to upgrade to the latest SenseCraft, the screen keeps returning to the Arduino program that I loaded previously. How can I reload the boot loader into the device?

I found out that I did not actually overwrite the boot loader. I just need to keep trying to slide the power switch to the third position and release until it enters the boot loader mode.
