eVic VTC Mini temp mode stopped working

I looked around for an answer, but no luck so here goes........
My wife has been using a VTC Mini with Cubis tank on TC for a few weeks with no problems. She uses the SS316-0.5ohm Heads, set at 25 watts and 400-420F. It's been working fine and tonight she wanted me change out her coil as it wasn't working well anymore. I popped in another coil from the same pack, primed the head, locked the resistance and gave it a couple of quick draws, like I always do. When I gave it back to her she said it wasn't working correctly, so I tried it. It was jumping into temperature protection after just a second and shutting off the current. I raised the temp to 450F and it would sort of work, but the vape would get week and flutter when it started to hit the temp protection. I thought maybe it was the coil, so I replaced it with another. After this, it would not fire at all in TC. I tried letting it cool and resetting the resistance. It read 0.52, but then popped up to 0.57. I can use it in power mode, but not TC mode. Any ideas? It's not all that old and I hate to think it's crapped out already.

check all the connections, strip the tank down as far as possible and clean it.

also check the 510, I have been using a theoren copy which pushed the 510 pin too far, so when I put my lemo 2 back on it wouldnt connect at all. There are vids on YT on how to get to it. Its basically 4 small screws, pull on the battery tab and hold the plastic ontop of the positive pin at the top to stop the spring popping out.

Thanks Sucram. I was kinda thinking about doing just that. I'll give it a shot tomorrow.

Well, it seems to be working again. I did the push the fire button without a tank to trigger that new coil signal and selected new coil and it seems to work now. I did raise the temp from 400-440F to get it to stop hitting protection quite as fast. I'm not sure why this worked as I thought the new coil thing just reset the room temperature resistance, which I had tried manually before, without fixing my problem. Maybe it does something else? I'm not sure.
