Unable to update signed bootloader

I have Uploaded Signed Bootloader and firmware.
Hi , I am stuck at bootloader update process. I want to follow your solution given on Cubepilot.org. the difference is my board is CubeOrange Plus STM32h757 and Ardupilot - 4.5.7. I have got St-Link V2 and ESP32S3 DevicekitC-1 also. How can I use this to solve my problem.

I read your solution for bootloader update on Cubepilot.org(How to activate DFU mode on cube orange plus.)
I am sending the link of your solution.
How to activate DFU Mode on Cube Orange+ - #4 by sidbh - Cube Autopilot - Cubepilot
Please guide me for that.

Should I use the deviece marked in red Rectangle to connect Cube orange plus with ESP32s3?

Hi @developer123,

Thanks for the report.

This apparently something has gone wrong installing a secure bootloader as described here on the AP wiki.

This is not something that I’ve ever done but hopefully we can get some feedback from other developers.

Okay, thank you so much

Hi @developer123,

We discussed this at the weekly dev call and at least one dev has successfully followed the process on outlined on this page including backing out the signed bootloader.

Can you try following this process and report back?

Thanks for the reply.
I have already tried this but can not connect to CubeorangePlus because in device manager,the device displays as CubeOrange±Secure-BL-v10 not as Mavlink COM so unable to establish conectivity with the board. Please check the image I am attaching here.

Thank you again.
