How to stop rebroadcast/ and send new tx with higher fee.

[jofus]

Hello all, I did a cold spend from a paper wallet to my friend (using Mycelium) and I used a fee that apparently is to small to ever get cleared.

I have read that the tx will get dumped out eventually from the mempool and then I can send with a higher fee, but I think mycelium keeps rebroadcasting it when it does.  I may be wrong about this, if so then please let me know what I can do to resend this TX so he will actually receive it. 

On a side note I saw the option for "child pays for parent" but when trying to use it, it gives me a "unable to build tx" error.  Maybe its because there are no funds left on that paper wallet to increase the fee with?  I'm not sure if that CPFP tries to rebuild the tx for the same amount plus a higher fee or if the whole tx is suppose to be editable or what. 

Anyway, any help would be great, I've been scouring the web with not much for answers.

Thank you

CPFP = "Child Pays For Parent"... it tries to spend an "unconfirmed" output from a previous unconfirmed transaction with a massive fee, such that the total fee for both transactions is large enought to get both transactions confirmed.

To prevent Mycelium rebroadcasting, you may need to "not use Mycelium" for an extended period of time... possibly uninstall it to ensure you don't accidentally open it. There is not guarantee that this will work, as it is possible that someone else is actually rebroadcasting the transaction and not your wallet.

Also, when you start Mycelium after you have noticed the transaction drop off the various block explorers... it's possible it will simply rebroadcast the transaction again. You might find you'll need to wipe the app data and restore your wallet from seed to make sure this doesn't happen.

Thank you. 

So if waiting for it to drop off the network may not work as someone else may keep rebroadcasting the TX, what can I do to get this TX through?  I have heard I could possibly rebroadcast it with a higher fee, but my wallets won't let me because it considers the funds spent already.

If you had the private key of your wallet try to recover it in other wallet like electrum. I think once you send your bitcoin address only the network can rebroadcast your transaction.
If you use electrum wallet i think you can have more option to do some ways to push your transaction.
You can rebroadcast it here http://eligius.st/~wizkid057/newstats/pushtxn.php

You can only rebroadcast with a higher fee (Replace by Fee aka RBF) if the transaction was marked as "replaceable"... I don't think Mycelium supports RBF and I don't think it marks transactions as replaceable

Even if you imported your private key into another wallet, you would still not be able to do an RBF... you'd have to just attempt a good ol' fashioned double spend... but generally, most nodes will reject your new transaction as a double spend unless it is specifically an RBF attempt

I have tried uninstalling my mycelium wallet in order to prevent the rebroadcasting of transactions no worries your coins will still be in your wallet, this way you can easily ensure of cancelling your transaction in order to process your transaction into a higher way of payment, just make sure to save and never forget your private to backup your funds safely.
