It’s no trouble at all, and thank you for sending the new log files.
From them, it seems we have a series of issues we need to work through. In order:
The gibberish below, paired with buffer overflows, is usually a symptom of insufficient power supply, where the Shake cannot get enough power to either start or work properly.
2025 282 09:43:54>> No Data has been received from the MCU in 12 read attempts.It appears the MCU is not transmitting data. This is a fatal condition and should be investigated if this condition persists!
2025 282 09:43:54>> Data has been successfully received, fatal condition resolved.

It is recommended that you check whether the current power supply continues to deliver a stable voltage between 5.0 and 5.2V and a current of at least 2.5A at all times (3.0A if the Raspberry Pi board being used is an RPi4), as a decrease in power could lead to data service interruption. If you have another Pi power supply that you know is in working condition, please try exchanging the current one with that and see if the Shake now appears more stable. If you have an official Raspberry Pi power supply to try, all the better.
As the WiFi was already off on the GUI (thank you for confirming this), but it still appears “ON” in the log files

this may indicate that the software on the microSD card has been corrupted. I would then advise to re-burn a completely new microSD after formatting and erasing all its data/partitions (you can use DISKPART for this, as it is very efficient), and then see how the Shake behaves with the newly installed system together with the new power supply, possibly resolving the issues we are seeing. I will leave the link to the burning instructions here for your convenience: microSD card topics.
If the Shake still doesn’t connect after these two operations, please download the new logs and send them to me so I can check how the situation is progressing.
Thank you for your collaboration.
