Hello reelfoot,
Thank you for the new logs and the screenshot. I can see the same from my side.
The good news is that the Shake is booting properly, and everything starts as it should. As proof (even if with gaps), data is being recorded and is flowing to our servers.
To address the gaps, however, these lines show what’s going on:

2024 191 18:24:02>> Data has been successfully received, fatal condition resolved.
As you can see, the logs you’ve provided contain some “gibberish” mixed with “no data received” errors. These are the reasons why we are seeing gaps in your Shake data stream.
My first thought would be to check and see if the current power supply you are using is continuing to deliver a stable voltage between 5.0 and 5.2V and a current of at least 2.5A at all times, as a decrease in power could lead to data services interruption. If the data interruptions continue to happen, and if you have another Pi power supply that you know is in working condition, please try to exchange the current one with that, and see if the Shake now properly works for longer periods.
A second check that you can do is to see if all the connections between the sensor, the blue Shake board, and the Pi board are still solid and free from dirt or any other element that could compromise transmission. As you have recently reassembled the instrument with a new Pi board, you should find this process quick and easy (but guidance is always available, if required). And, as usual, if you decide to disassemble the Shake when doing this, please make sure you are using proper ESD (ElectroStatic Discharge) protection (such as gloves, etc.), as electronics do not like static electricity too much.
As a last resort, and if all these checks come out as positive, then I would recommend re-burning the microSD card again (or using a different microSD) after formatting and erasing all its data/partitions first (you can use DISKPART for this as it is very efficient), and see how the Shake behaves with the newly installed system, removing potential issues derived from corrupted files. I will leave the burning instructions link here for your convenience: microSD card topics
Thank you for your collaboration.
