keepkey p2sh-segwit wallet can't spend

[SomberNight]

On git master 4e60cedea9c295b2c2fa62b94d20eba3c515e5d9.

Keepkey standard wallet with p2wpkh-p2sh script type (BIP49 derivation path) fails to sign unsigned transactions.

Typical 1-in 2-out tx.

Tested again on 3851e78454f559ec4368a4b04dd61c2b9a1f9dc1 with python-keepkey 4.0.2. Issue still persists.

can you try to just sign the transaction and broadcast it using a different tool like blockchain info pushtx ?

[SomberNight]

can you try to just sign the transaction

Sign how? Using a different tool? The problem occurs when I try to sign it using Electrum.

I too have coins trapped on BIP49 keepkey. Are these lost permanently or could these be recovered if keepkey upgrades firmware?

[SomberNight]

@bitsolemn No, not trapped. You can:

• use Electrum in combination with a different hw device (Trezor, Ledger, Digital Bitbox all support p2wpkh-p2sh) initialised from the same seed words
• use Electrum to create a software wallet from the same seed words (enable the BIP39 option when restoring from seed)

Ah right. The stress clouded my thinking. Thanks~
