Wismec doesn't vape on TCR after update

[Silex7]

Hello vapers,
I have wismec rx 2/3 running with Crown II tank stainless steel. First I was vaping on TCR M1 mode and it was doing great..but today I updated my wismec firmware to the latest version when I tried to vape on my previous settings it won't vape and only gives me a verrrrry weak vapors (as 10W or something) I tried to increase wattage and adjusting temperature but nothing change..
When I switched to VW wattage or TC Ni modes it vaped normally,..so why is that? Does that has something to do with the new update for not to run on TCR ?

Any help is highly appreciated

On mine it turned out to be the pin that touches the mod. I just skimmed it with an emory board a few times and there was no problem since.
