Restoring seed problem

I'm trying to move from a bitcoin.com wallet to Electurm.

When creating a new wallet, I select "I already have a seed" and then type it out the 12 words, but the "Next" button remains grayed out.

The only time I can click "next" is if I select BIP39 from the options. However my wallet is not BIP39, it's BIP44.

What am I doing wrong? I can't figure this out. Thanks in advance.

Are these 12 words generated by bitcoin.com? If yes, there is no purpose on importing them on electrum since they still have access to your money. This doesn't answer straight to your question, I just want to warn you.

Electrum follows the BIP39 standard and its own seed generation standard. I'm not sure, but I don't think that bitcoin.com follows any of them (surely not the last one). You simply can broadcast a transaction spending all of your bitcoin.com funds to an newly generated address from electrum. (from a newly generated seed)

If the checksum passes, then it is probably a BIP39 seed. BIP44 is the standard for the derivation path, BIP39 defines the mnemonic standards. If you click next, you should be able to choose the derivation path. You can let Electrum decide the derivation path automatically and it should work.

So I should just select BIP39 then?

It was originally on an old Bitpay wallet. A few months ago I transferred to bitcoin.com, but it's awful. A friend said Electrum is the best wallet, so I want to transfer there. It's the same 12 word code as before when I originally transferred, so it was not created by bitcoin.com.

I can create a new wallet and transfer the funds, but I didn't want to pay any fees, so I really wanted to move the wallet instead.

I just installed bitcoin.com wallet on an android phone just to see how it works.
It does generate BIP39 seed phrase.

Below is the seed I just generated using bitcoin.com

Yes.
And check "legacy (p2pkh)" in the next step.

I selected BIP39 and clicked next. I then selected P2PKH as the type and it created the wallet, but it's empty. My funds don't appear.

My wallet is old, it's BIP39 and P2PKH. How do I upgrade to a newer wallet with Segwit etc? Do you have to transfer from a old wallet to new wallet every few years and pay the fee? Is that's the only way to get an updated wallet?

I checked wallet information" and for "Seed available" it says "False".

Does that mean it failed?

Great, I'll know this for the future, but unfortunately, in this case he/she said that the seed phrase wasn't generated with bitcoin.com if I'm not mistaken.

If you want to upgrade to a newer address format like segwit, you'll have to send the funds from your legacy wallet to the new one. There is no other way to do that. Can you clarify the part that you moved to bitcoin.com? You generated the words with bitpay and then imported your phrase on bitcoin.com? What exactly did you do?

That's one of the thousands disadvantages of bitcoin.com. You pay a huge fee. On electrum you can select any fee greater than the dust amount. (which is really small)

Restore again and this time, click detect existing accounts.

No. Your wallet is not old, it is just a P2PKH format and Segwit is a more efficient transaction format. You don't have to "upgrade" your wallet if you don't want to. People upgrade to Segwit to save in their fees but that doesn't mean it is mandatory. If you want to create a segwit wallet, generate a new seed with Electrum and send the funds there.

No. Electrum doesn't store the seeds for BIP39.

Blockchain.com is BIP39, you are right.

Although this is not in relation to what you commented but just an addition. One thing I hate about the wallet is that it does not support nested segwit and native segwit. Although, I have ones a time imported the seed phrase generated from blockchain.com on iamcoleman before, and it worked like normal seed phrase and generated all the necessary derivation paths, and the first address is the same as that of the blockchain.com wallet, but on the wallet itself, only legacy is supported, and this is just one of the ways people are unknowingly wasting bitcoin on transaction fee.

If the seed phrase is not working, the fault is from the person that is importing the seed phrase. Maybe he is imported another seed phrase, or maybe he is not checking the box for BIP39 right on the electrum wallet.

If yes try to restore it again with Electrum with your seed and enable BIP39.
After that go to wallet>information and look for xPub copy the text and paste it here https://blockpath.com/wallets/new?action=appxpub

It will scan all possible derivation paths and show all addresses with balances and used addresses.

Once you found some used addresses with balances use the derivation path shows from the result and restore it again in Electrum but this time use the derivation path that you get from xPub Analyzer.

This only works if your wallet before has used addresses.

I don't think Bitcoin.com uses any nonstandard derivation path and OP stated that it's BIP44. The built in function should serve OP just fine and won't be leaking that much privacy nor add any extra complexity.

I tested that.
I generated a seed phrase using bitcoin.com wallet and imported it into electrum. I got same addresses without any trouble.
The derivation path is m/44'/0'/0'.

I selected BIP39 and clicked next. I then selected P2PKH as the type and it created the wallet, but it's empty. My funds don't appear.

This is weird!
BitPay uses bip39 and m/44'/0'/0' (legacy P2PKH) as derivation path by default. Checking bip39 from advanced setting and selectin Legacy P2PKH when restoring your wallet on Electrum should generate the same wallet (same addreses)!

Check the receiving addresses on Electrum if they match the addresses on BitPay. If they do and you still can't see your correct balance, then most likely Electrum is not connected or didn't finish syncing.

Can I ask which kind of "Bitcoin" is it? You might have bought the wrong one.
Because Bitpay and Bitcoin.com wallets both support [BCH] Bitcoin Cash and [BTC] Bitcoin, while Electrum only supports Bitcoin.

If it is BCH, restore it to this fork of Electrum instead: https://electroncash.org/

However my wallet is not BIP39, it's BIP44.

BIP44 is not a mnemonic algorithm, it is just a derivation path definition.
Basically BIPs are like this:
BIP39 is the mnemonic algorithm which is equivalent to the different algorithm Electrum uses.
BIP32 is the key derivation algorithm which doesn't matter what mnemonic type you had, they all end up using the same KDF in the end.
BIP44 (and some others) are defining "standard" derivation paths that are used in BIP32 to derive each key.

Do you see any history at all... and your balance is zero... or do you see absolutely nothing at all? Is the "dot" in the bottom right corner of Electrum Green? Red? or some blue arrows? Huh

Restoring a BIP39 seed an using the m/44'/0'/0' (legacy P2PKH) derivation path should generate the same wallet as used by BitPay and/or Bitcoin.com.

^-- This... Bitcoin.com has a really bad habit of making users think they're buying "BTC" Bitcoin... but they're actually buying "BCH" Bitcoin Cash Undecided
