Exactly. When you create a new wallet with fw 1.5.2, it's a SegWit wallet. You have to look at the legacy wallet to find it.

Yes. Electrum 2.9.3 restores the legacy wallet.

Finally got it.
The issue is related to SegWit, implemented in Trezor fw 1.5.2.
Default wallet created with this version is compliant with SegWit, but Electrum 2.9.3 is not. It can't restore those wallets.

With fw 1.5.2, you can still create legacy account that can be restored with current version of Electrum or ArcBit. The option exists in the bridge GUI.

I wish to restore my Trezor bitcoin account with Electrum using my seed.
The restore seems fine, however, I end on another account, intially with no credit. I've put some coins on it, it does not show on my trezor. Clearly, this is 2 different purses.

Using Electrum v2.9.3
- I do a Restore
- Enter my 24 words seed (I'm really sure this is the right one)
- Leave "Extend this seed with custom words" blank (Because the passphrase is not activated on my Trezor)
- Check "BIP39 seed"
- Leave derivation to default (m/44'/0'/0') <- Could be the issue ... ?

I've also tried to restore with a blank passphrase, same result.

Can someone explain me what's wrong ?
