help needed: Import priv key from electrum bech32 address into core

[bspus]

Here's the situation

I'm trying to claim sbtc. I have claimed from legacy addresses already. There are lots of tools to make that relatively painless.
It's a whole different story when it comes to segwit bech32 addresses. Those are the ones that start with bc1.
I have gone as far as actually downloading the sbtc core wallet and it's syncing. Whatever online wallet for sbtc I found was either a scam (like those sbtc electrum ones) or did not support those addresses.
But even so, it seems my troubles are not over.

Now I'm not asking anyone to help with sbtc core, just bitcoin-core which I assume will be very similar for this process. I understand there is no gui function, I'm OK using the cli for this.
As I said, the private key is exported from electrum bech32 address. Can core parse those? Do they need to be converted with some tool?
I'm surprised that a google search has provided no step by step method. I'm starting to worry it might not even be possible.

Bech32 addresses/private keys can be converted into legacy addresses/private keys. They both hold the coins (technically) but the segwit address allows it to be signed into a smaller transaction size.

Wonderful, thanks!

If I understand correctly, I didn't even need to mess with the sbtc core wallet. I should just be able to convert into legacy priv keys and do the job with those.

No, "legacy" private keys will correspond to non-segwit addresses. You will need to convert the non-segwit address into a segwit address. You can use the sbtc core wallet and use the addwitnessaddress command once you import the WIF private key.

Thank you. I was about to write that what I tried didn't work. Those modified priv keys gave legacy addresses that, naturally, had no transaction history. I'll try this command when possible.

Using addwitnessaddress with one of the newly derived addresses (with the "legacy" private keys) returns an error because "segregated witness is not enabled on the network"

Is that actually the case or is it just a parameter I need to change? Has anyone actually claimed forked coins from such addresses?

Is your wallet fully synchronised? That's normally what causes the issue of it not being enabled on the network yet (as you haven't gotten up to that block so core doesn't know it's been activated).

Right... I imported the first address and took about 15 minutes to rescan the whole thing. Since it doesn't give me an option to add all my addresses and add witness address beforehand, I thought I could be clever and do it on an empty blockchain wallet, then take the wallet dat to the synced client. But no... it has to give me grief 

This whole thing proved more trouble than it's worth but I'll give it one more chance to see it to the end. I should be very close now.

Im using Electrum myself for segwit stuff for the time being. I would just wait until 0.16 is out which will have support for all segwit addresses and you will see them on the GUI and everything will be as it should. 0.16 should be out next month.

But if there is not a way to add addresses in batches and then rescan, I will just not do it, I will keep whatever addresses I've used so far in the Electrum wallet. Im not going to spend ages importing my addresses to be honest, I don't have that much money in segwit addresses to bother.

[bspus]

Yes indeed, nothing worked after all. I still can't see my segwit transactions.

I'll wait for 0.16 and hope sbtc updates their version soon after.
