LR1110TRK1CKS-JP Tracker reference design reset to EU868

[Mathannbala]

Hi, I was given this tracker and when trying to onboard it to my platform, I noticed that it was unable to join the network. Following the guide on the Lora Edge config guide, I tried to reset the device to see if it was able to join the network thereafter, but it reset to EU868 and I'm unable to change it back. Is there a way for me to re-flash the firmware again using AS923-1 region? I'm also testing out the LoRaWAN Relay, so if possible I would want to update it to the latest version so that it is a relay-compatible end-device. Can I seek assistance on how to go about doing this? Thank You.
