So after working with support, it turns out my ColdCard is genuinely fucked up after a firmware upgrade and now there’s a brand new replacement in the mail coming my way.
After this experience I don’t think I can ever upgrade my new ColdCard’s firmware. Some day I won’t have warranty on it and if it gets bricked again I would need to buy a new one.
You could always recover to a different wallet, but that doesn’t ease the money you’d be out having to buy or build one.
I know, but I don’t want to have to buy a new one just because
If you use sparrow, and you have 24 words, what is the point of having a third party hardware signing device? Could you not just use Sparrow on a laptop every single time? This would obviously involve recovering or importing the wallet each time, but couldn't you just opt out of having a device in general?
I wouldn’t do that. Having to enter my seed phrase on a vulnerable machine every time I need to do a transaction seems highly risky to me.
Makes sense. I've been limited to stacking only the last 6 years so haven't sent many tx's. Just did first two consolidations on small utxo's yesterday. Never really messed with Sparrow before that.
Your point is that if you have the hardware device, the keys never get entered on the laptop?
Thanks!
Yeah, I would say definitely never do this
I wasn’t talking about using an Internet connect device to sign, I was talking about using your 24 words to sign in a fully off-line way with a new signing device, if your cold card dies
Well that’s fucked?
What model of cc?
Sorry to hear you are going through this.
But this is a bit odd. Are others experiencing similar issues after the upgrade? Or you feel you are alone in this.
No idea how widespread this is
No problems here since the upgrade.
Was this device just upgraded or have you already been operating with it for a while?
Since December 19th. And I have already done transactions with it.
