Description
**Device**: LILYGO T-Display-S3
### Background
I purchased the device and flash the Jade latest firmware with secure boot enabled.
Everything works but I forgot to disable the DEBUG log output which could cause the Sparrow wallet failed to unlock the device.
So I try to do the OTA update with the DEBUG log disabled firmware.
The OTA result shows **successful** on both the device screen and my computer's terminal.
### Problem
After I reboot the device, it became this:
### Is it possible to save my device?
I tried to flash the firmware again by using `idf.py` tools but it failed due to
```Serial port /dev/cu.usbmodem101
Connecting......................................
/dev/cu.usbmodem101 failed to connect: Failed to connect to ESP32-S3: No serial data received.
```
I think it's caused by the secure boot.
So can I save the device on my own? Or I have to send it to the manufacturer to rewrite the chip?
