I have a Trezor wallet, which I misplaced. Following Electrum´s tutorial, I inscribed the 24 words of my seed recovery pass. But they are not recognized. For, after that step, it does not offer a NEXT button. Only a RETURN button or OPTIONS. When I click the OPTIONS button, it appears: Enlarge this seed with personalized words, and it specifies further:  SEED TYPE, with 3 types: Electrum or Seed BIP and another BIP.
What shall I do?
There is something wrong and it is not my fault, for I am doing it with an informatics manager with long experience.
Thanks.

Your trezor uses BIP39 (https://wiki.trezor.io/Developers_guide:Cryptography) and not Electrum's standard for mnemonics. Click the options, check “BIP39 seed” and then click next. That should fix your issue.

If the seed was created by Trezor, then you will have to enter the seed, click the Options button under it, click "Bip 39 seed" and it should be accepted.

Then, on the next step, depending on how were your addresses starting, choose:

* Legacy if it started with 1
* P2SH Segwit for 3
* native SegWit for bech1

I guess this will fix your issue. You can see a step by step guide here (https://coinguides.org/import-ledger-trezor-seed-electrum/)

But remember that your seed phrase is already "exposed" as you entered it in an online computer. You should now buy a new hardware wallet (trezor or ledger are the best options) and generate a new seed with the new device. Then you need to transfer those coins from your electrum wallet to the new wallet you just generated with your new device.

You should not import seed words from cold wallet like trezor to any hot online wallet that is connected to internet, but if you do that you should consider that those seed words are now compromised and don't use them in future.
Using electrum wallet in combination with airgapped computer is one possible option if you enable BIP39 seed option.

It's true that exporting the seed into a hot wallet is not recommended as it defeats the purpose of using a hardware wallet in first place (cold storage), but I don't think it's necessary to buy a new device. I've never used Trezor before but I am almost sure it allows creating new wallets. So instead of buying a new one, he can wipe his Trezor then generate a new seed.This should be as safe as buying a new one (but less costly).

That would be the preferred option... If he hadn't "misplaced" his Trezor ;)  He can't reset something he doesn't have! :P

Sorry about that. It was due my misinterpretation of the word "misplaced". I thought it meant he lost his hardware wallet for a short time then found it or he left it in a non-safe place for a while and feared if someone got access to his wallet seed.
If the device is lost for good then, obviously, the best thing to do is to create/buy a new wallet and move his funds to it, asap.

What do you mean by "Informatics Manager"?
If it's someone who've contacted you randomly after posting the first thread (guess there was, because of the title),
please do not hand over your 24-word phrase or private keys to him or anyone and just follow the first and second reply in this thread.
