Mnemonics checksum issue

I have the same issue. I use the words from the Helium App. I can recreate my Wallet in the App with exactly these words, but when I try them with Keypair.fromWords, i get the same error above ("Invalid Checksum at Mnemonic.toEntropy "). Other example words from e.g. the testcases work fine.

[kellybyrd]

From working on the helium-wallet-rs project, there is code there that handles the always 0000 checksum of phrases generated by the mobile wallets. Is this that issue? If so, is there a plan to move the mobile wallet to generating valid BIP39 checksums?

UPDATE: Not sure this is related. I filed #188

Do you have a resolution to this problem you can share?

JFI: The solution to my case was that I used only lower case letters in the words.

[kellybyrd]

Please tell me if I'm missing something but this word list should never work: abandon', 'ability', 'able', 'about', 'above', 'absent', 'absorb', 'abstract', 'absurd', 'abuse', 'access', 'accident'

It is not a valid 12-word mnemonic. You can't just pick the last word. It has to be calculated based on a checksum. IIRC for a 12-word phrase, the checksum is the lower 4 bits. So there would be several valid word choices, but it is unlikely 'accident' is one of those valid choices.
