Hi

I need some help.
I am trying to reach my Erc20 tokens on my Trezor but i cant send them.
I cant send them because of i think i need to update my firmware.
 So i can go to vintage.myetherwallet.com and i can see my funds there in my wallet but i can not send it.
And i would like to send it before i update because it looks like the device will be cleaned out when i update.

I do not remember that i have to get my seed when i have updated the firmware.
So is this normal that i have to go and get my Seed every time when i update the firmware?
