Here's the TREZOR that's got Bitcoin stuck on it.

I can't remember the pin code and I've tried a bunch

of times and this is my last chance

to get the recovery seed out of it.

So I cracked it open a little earlier,

I think it was yesterday.

The WiFi is off, now let me see, hopefully,

if I have this path, if that pass way is turned on,

I'm screwed.

Password price protection is false.

[Woman] Yeah.

Okay, that's the thing I was worried about.

Camden's version 1.1.4.0, so we're good there, okay.

It says make sure not to lose power to the TREZOR

from this point on.

Hold down both buttons and short the reset

and ground pins on the left.

Okay.

Oh my God, I'm shaking.

(laughter)

[Woman] Dada, this is just a test run.

It is?

[Woman] Just think of it that way.

Continue, erasing, installing, compare fingerprint,

you may un-click, do not unplug.

Okay, I think we're in, but I need to short these again.

It'll say warning, unofficial software detected.

Compare fingerprints, x point.

[Woman] Yeah.

Okay.

We're getting close.

(exhales loudly)

Oh my God, it worked.

[Woman] Oh my gosh, oh my gosh.

[Man] I'm gonna take a picture of this.

Okay, now I'm gonna get the pin code.

Oh my God, I can't believe--

[Woman] This is fantastic.

Oh my God, we got it.

[Woman] Oh my gosh.

There's the password.

[Woman] Yay.

Yeah.

(laughter)

Oh my God, we got it. Yay, oh my God.
