 What do you guys recommend I use to recover a frozen Bitcoin wallet? 
 What's a "frozen" bitcoin wallet? 

I would probably sweep it into Trezor and then transfer to a modern address.  
 Via Electrum on a Tails booted laptop...  
 A self-custody wallet managed by a buggy app. 
 What exactly is your problem? 
 Relai locked me out of the wallet. 
 😱 so it’s a hot wallet. In this case I would recommend to recover the wallet with sparrow or electrum 
 I have a hardware wallet, too, but it's a Ledger. 
 I wouldn’t recommend to use a seed phrase generated with a phone on a hardware wallet. In worst case your seed could be already corrupted.

For security reasons I would always separate hot and cold wallet seeds and not mix them up.

Technically it’s possible to recover your relai seed on a ledger or any hardware wallet that supports 12 word seeds but it’s really not a good practice.

The best way when it comes to security is to recover a hot wallet seed with a hot wallet like sparrow or electrum and then send your funds to your cold wallet.

This way ensures that you don’t mix up seed phrases. 
 Yeah, I'm going with Electrum Android, I think. 
 It worked! I was nervous to type the seed phrases in, until I realized that the worst that can happen, is that I accidently get someone else's money. 😂

Already sent some to my Phoenix wallet to pay my LN bills and the rest to Ledger.

 Thank you, everyone! 🥰 
 No the worst that could happen. The worst could be that you use a fake Electrum or a corrupted keyboard or worst that steal your coins, but in most cases everything is fine.

Best is to use a Tails OS stick (installed properly with signature checking and all), boot it on a trusted computer, run Electrum (included), enter seed, send all to you hardware wallet. 
 can't go wrong with electrum 🤙 
 have you tried temperatures above boiling point? 
 Recover using the 12/24 words to a new device or even temporarily onto a software wallet like Sparrow. 
 Sparrow isn't offered in Germany. Electrum? 
 I thought sparrow was open source and not region specific? 
 I was looking at the Play Store. Let me see... 
 Whoa. Looks complicated. 
 Yeah, I have yet to play with it but it gets a lot of praise. 
 No Android version. 
 Yeah desktop only I think. 
 Yes, Sparrow is a desktop app.

It is very powerful (fully featured), so requires some degree of knowledge to use it, but mastering this wallet will give you a much greater understanding of how Bitcoin works.

If you are unfamiliar with it, I suggest you setup a new wallet on it, transfer a small amount to this wallet and play with it, explore how it works, perhaps google its operation or watch a YouTube video or two.

 @BTCsessions does a very good tutorial on it:

 -Signing device airgapped or a hw with USB.
-disconnect all data and hard drives, use Tails OS, use sparrow or electrum, export the xpub, make a psbt, broadcast the tx. 
 Call the btc helpline?

Sorry… I’d start with seed phrase in a new wallet, can’t you get Sparrow via a VPN? 
 Is Sparrow so much better? 
 It’s just what I’ve been using for a couple of years now. Any wallet should work though I guess. Do you have the derivation path? 
 I used Electrum Android. Works well enough, apparently. 🤷‍♀️ 
 I miss Muun. 😭 
 That was such an underrated wallet. Always worked. 
 until the fees went up.. then it stopped working.. 
 😭 
 Microwave 
 Electrum wallet  
 That's what I used. 🙏🏻

Worked very well. A bit clunky, but it gives lots of information, which is oddly reassuring.
Relai tried to hide the complexity, so problems just look like mysterious, evil magic.
