Please update the image you uploaded.

If you mean verifying the mycelium backup of yours, make sure you (double or triple check) copy the random password checksum generated by mycelium and try to scan each encrypted privkey on pdf file using the mycelium app.

I'm not familiar with the signature messages generated by Core itself, but is this the right format? All wallets I have seen use this format for the signed messages:

Code:
-----BEGIN BITCOIN SIGNED MESSAGE-----
Message here
-----BEGIN SIGNATURE-----
Address here
Signature here
-----END BITCOIN SIGNED MESSAGE-----

Edit: nevermind, I believe this is just a placeholder. lol

Mycelium is able to "verify" a signed message created using another wallet... like this ones you can find in the "Stake your Bitcoin Address" thread (https://bitcointalk.org/index.php?topic=996318.10440). That "Verify Message" menu option allows you to copy/paste a signed message and verify that it is signed correctly.

However, if you want to create a signed message within Mycelium, you need to select the account you want from the "Accounts" tab (tap it so you get the popup that says you're "working" with that account"... then click the 3 dot menu and select "Sign Message".

If you are using an HD account, it'll prompt you to select which address you want to sign with...

Then, you'll be asked to enter message:

Type your message, then you click the "sign message" button and you'll get the signature:
https://talkimg.com/images/2023/11/15/z552c.png


Which you can then copy to clipboard or "share"... and you'll get something like this:
Code:
-----BEGIN BITCOIN SIGNED MESSAGE-----
Test message signing in Mycelium by HCP. 2019-10-31
-----BEGIN BITCOIN SIGNATURE-----
Version: Bitcoin-qt (1.0)
Address: 129Zb5FULziPrkNBwkXaeKmSVphxM1gnZ3

H0d/o5r0EgqW6WI+hSOdLqN48j2JQatTEW1aT8vZgiTMfntPxugltY3Y1wrl6yFIMdKP5Ju/st28NBZTrLJAmus=
-----END BITCOIN SIGNATURE-----

Which can then be verified using something like BrainwalletX: https://brainwalletx.github.io/#verify?vrAddr=129Zb5FULziPrkNBwkXaeKmSVphxM1gnZ3&vrMsg=Test%20message%20signing%20in%20Mycelium%20by%20HCP.%202019-10-31&vrSig=H0d%2Fo5r0EgqW6WI%2BhSOdLqN48j2JQatTEW1aT8vZgiTMfntPxugltY3Y1wrl6yFIMdKP5Ju%2Fst28NBZTrLJAmus%3D


NOTE: if you select an address starting with a "3"... it is highly likely that it will NOT verify properly on BrainwalletX and will only verify in Mycelium, or Electrum or possibly Trezor due to issues with signing messages from P2SH addresses.

Let me ask if what is your purpose why you need the "verified message"? I'm confused about this "Some day ago i download mycelium app for holding bitcoin already collected mycelium backup key"

If your plan is to restore your wallet with backup key phrase what you need to do is to restore it and provide the backup key phrase after that you can use your old wallet again without issue.

But if your plan is to verify a message you can use any 3rd party like this one https://blockexplorer.com/messages/verify

Just put the address, message and the signature then click verify if it shows "An error occured in the verification process." it means the message or signature is incorrect or the message is not generated from your address.

Better let us know the reason why you need the verified message?
