Downloading Bootloader 1.1.1 and flashing using ST-LINK allows the Python driver to find the board, but it does not connect to https://developers.aceinna.com/ (UPGRADE button in https://developers.aceinna.com/code/apps greyed out)

From https://developers.aceinna.com/code/apps it allows you to download the bin file e.g. OpenRTK330L_GNSS_RTK_INS_v23.05.bin but there is no instructions on how to use ST-LINK to apply this downloaded file to the EVM.

I just paid like $500 to get this EVM 2 days ago from Mouser, and already got stuck while trying my best to follow the instructions. A single click of the "UPGRADE" button on https://developers.aceinna.com/code/apps on one of the "OFFICIAL" app caused all this trouble. Due to the complete lack of technical support I am seriously considering returning the whole thing to Mouser.

The orange/green LED now slowly flash like it did before. But I cannot connect the Python. After I unplug the power and plug in again, no lights come on, not even the rapidly flashing green LED. What do I do?

Do I need to apply the calibration data since I erased everything using ST-LINK?
I went to https://developers.aceinna.com/devices/owned/2075000294 clicked "DOWNLOAD" under "Calibration Data" but got
"There is some error while generate download link. " Can you fix it? Also please let me know the instruction to apply the downloaded calibration data.

Please also help me with my other thread to get the INS to work to get higher than 1Hz fix update rate.

Can you help me out?
