The Therion is a great mod. But just to clarify, it's not made in the UK, it's a Chinese product as well, using a DNA board, which is a US product and does have great customer support in the US. Not sure how LV and Evolv handle things in the UK. Regardless, it's a great mod.
I am also having the same trouble.
I guess I made the update in a wrong way, I didn't hold the fire button. When I finished updating, device freezed as it writes 'updatting'. Yes it was "updatting", I did not misspelled.
It freezed like 15 20 mins. Than died totally
It was my second day with this device.
I recommend everybody for not to update those devices.
Now when I plug it to pc, a sound comes up like I disconnected a device.
When I try to connect with update tool, It says "No Such Usb Device".
Damn, I wish we all can repair by ourselves. Cuz If I send it to headquarters to get it repaired, I won't be able to get it back because these devices are not allowed in my country...
I am not disagreeing with your crappy firmware update experience, and think it's pretty bad, but it does not necessarily apply to all users. I received a v1.2.1 in mid October and upgraded straight to 1.2.2 with no problems and with good TC performance with 316L after inputting the correct TCR. As these problems are not universal, it's hard to know where the issue lies.
