What was the process to open it? Just cut it open? Since I can't see any screws.I opened up one of the Ultralinks and I must say it's very well made considering how I struggled to get in but more so how it's put together.
Going to be some serious work to serial flash that.
And to put it back together?
I had one that I tuya-converted to Tasmota, but it is going wonky now. Reboots every couple of minutes with a software watchdog exception. Unable to flash it to a newer of Tasmota, so I might have to flash it the old fashioned way.
