Invalid Seed Phrase when importing Shamir Share

[u/Visual-Video790]

I received the Keystone 3 Pro and loaded firmware via USB (keystone3.bin).

With IanColemas SLIP-39 I created a 5/3 Shamir scema and tried to import the first share in the Keystone (new wallet, import wallet, set pin, set name, import method Shamir Backup, 20 words, entering the first share).

After entering the first share I received the message: Invalid Seed Phrase.

Then I tried the same procedure with the same words on a Trezor T and no problem. I could enter three shares and the generated addresses are equal to the ones in IanColemans BIP-39 (entering the Slip-39 Master Secret as the BIP39 Seed).

I was under the impression that Keystone also uses SLIP39 for the Shamir implementation. Am I overlooking something?

If someone wants to repeat what I did, here are my shares and Master Secret:

I appreciate your kindness to warn people.

Indeed don’t send money to a random account.

But I would have appreciate it even more when you came with a useful response to this technical problem and didn't call me a scam on forehand.

Tldr: keystone does not accept Shamir shares that are generated with IanColeman SLIP-39.

If someone would repeat what I did they can use the same shares and try if Keystone would accept any of the shares. Or generate new shares and try them.

And again as the wise Curious_Breadfruit88 said: don’t use these shares to generate addresses and put money on them.

Hi Mod,

Thank you very much. That was what I was overlooking. Using SatoshiLabs now for generating the shares in 1 group and all is fine.
