easist way to get my BTCP by using a 24 word BIP39 bitcoin seed?

I have a 24 word bitcoin BIP39 seed from my trezor and now I want to claim my BTCP. what is the easiest way? ..I already tried importing it into Coinomi with different derivation paths (M/49H/H0/H0 and M/44H/0H/0H) but neither worked.
At the time of the fork I had coins on a legacy and a segwit address so according to everything i know both derivation paths should have worked but they just don't. I also tried 44H/183H and 44H/147H...
Should I just use another wallet? Any recommendations that provenly work for BIP39 seeds?

Easy shamir sharing for BIP39-like mnemonics (where each part of the secret is also itself a BIP39 mnemonic)

I made a simple tool for using Shamir’s secret sharing with BIP39-like mnemonics, where each part of the secret is also itself a BIP39 mnemonic. Just FYI in case it is useful for anyone in creating backups of their mnemonics.
A simple tool for generating and manipulating BIP39 mnemonics with special properties that make it easy to use the 2-out-of-3 Shamir's secret sharing algorithm (SSS) where the shares are also each themselves valid BIP39 mnemonics.
The code breaks up a mnemonic into three SSS shares that are also each themselves valid mnemonics. Someone coming into possession of a share will have no immediate indication of whether it is a share or is itself a mnemonic. Bonus: you can use the share-as-mnemonic property to create trip-wires to reveal if a share has been compromised (by funding a honeypot at a corresponding BIP39 bitcoin address, for example)

recovering bitcoin from bip39 phrase

Hi, I miswrote my 24-word bip39 phrase and thus have about ~250 candidate phrases that all pass checksum. I was wondering if there is an automated way (i can program it it doesn't exist) to recover my wallet.
I'm using a nano ledger S. It is 24 words without any seed. I tried Ian's : https://iancoleman.io/bip39/
but am not sure what to search for.

One idea I was thinking is to go through all candidates, generate the master public key and check on blockchain.com to see if there are funds in that wallet. I already know how many bitcoin I have, so it should be easy to compare.

Please advise, and if I'm able to recover funds, I'll send a reward for your time and energy! thanks!

Are all possible BIP39 mnemonic seeds produce a valid BIP32 master private key, which produce valid Bitcoin private keys?

The question is provoked by the fact that not all 256-bit numbers are valid private keys. To be valid it must be from 0x1 to 0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4140.
Is it possible that some randomly chosen (with dice, for example) mnemonic seed is not valid, because it produces not valid private keys? Is there a protection for this?
I know that Electrum can be configured to accept a random list of words (user-generated) and to ignore the incorrect checksum.
What is the risk something to go wrong by using manually selected words (selected with dice and "Bip39-diceware" for example)?
Edit: I looked through the documentation (BIP32) briefly and looks like I found the answer:
In case parse256(IL) ≥ n or ki = 0, the resulting key is invalid, and one should proceed with the next value for i. (Note: this has probability lower than 1 in 2127.)
So, it looks like there is a protection envisioned by the developers. Whew.
Edit 2: Actually, no.
In practice, this will never happen (the probability is so small we can ignore it), and likely implementations don't even bother checking the condition.
This is scary.
Edit 3: I tested Electrum. See "I successfully imported invalid Bitcoin private key! #5797" on the Github page.
Edit 4: It's not a bug, it's a feature.
SomberNight said on Github:
Effectively, with what we are doing, some group elements have two representations; while most only have one. Your "invalid" key contains a number that is too large to be a group element; but we subtract the group order from it and use that number instead. It's as if you imported the "valid" key in the first place. In fact if you try to export it, we will give you the "valid" one.

Been doing some work with BTCRecover so that it can now be used for BIP39 wallet recovery, even if you don't know the address... AddressDB functionality for Bitcoin has been broken for some time on the official repo and now works again + also now works for segwit and native segwit accounts :)

If I create a BIP39 seed and store it securely, how easy will accessing my bitcoin be in 10 years?

If my mnemonic seed is securely stored, and or memorized, what will my options be if I don't look at BTC for 10 years? If my mnemonic was generated via a mobile wallet using BIP39, would I be able to use any mobile wallet using BIP39? What if I wanted to move the funds from a paperwallet (or my memory) directly to a hardware wallet? Can I do so with the 12 word seed and nothing else? If I can't now, will I be able to in 10 years?

BIP39 or Bitcoin Improvement Proposal: 39 is one of the many design ideas that was approved by an economic majority of the Bitcoin community and became a standard for many popular wallets.. BIP39 is the use of a mnemonic phrase -- a group of easy to remember words -- to serve as a back up to recover your wallet and coins in the event your wallet becomes compromised, lost, or destroyed. Mnemonic code for generating deterministic keys. You can enter an existing BIP39 mnemonic, or generate a new random one. Typing your own twelve words will probably not work how you expect, since the words require a particular structure (the last word contains a checksum). BIP39 Mnemonic phrase is a list of words that store all the information needed for the recovery of a Bitcoin wallet.Usually, a wallet generates a mnemonic backup phrase by itself, so that the user could write it down on paper. If the user’s computer is broken or its hard disk is damaged, he will be able to upload the same wallet and use the paper backup copy to get his Bitcoins back. This page describes a BIP (Bitcoin Improvement Proposal). Please see BIP 2 for more information about BIPs and creating them. Please do not just create a wiki page. BIP39 and its flaws. BIP39 is the most common standard used for seed phrases. One notable example is Electrum wallet, which is using its own standard, and for good reasons.BIP39 has some flaws, known in the technical community but not known much wider. They are described here on this electrum doc page.Most seriously, BIP39 flaws mean it is not true to say that backing up a BIP39 seed phrase ...
