Need Help - Rebroadcast doublespend transaction

[Neotox]

One of my transaction wasn't confirming since long time  (10+ hours) so I did double spend with higher fees but now the problem is my second double spend transaction doesn't appear on blockexplorers.

Anyone can help me, how to broadcast second double spend transaction to bitcoin network?

Blockchain.info error -- Not accepting transaction version 2
blockr.io error ---- There was an error pushing your transaction to network! Did you sign your transaction? Is this double spend? Have you already sent this transaction?

Most explorers and nodes will refuse to accept a double-spend attempt until they have dropped the original transaction from their memory pool.

Typically (if nobody else is re-broadcasting your original transaction) this takes a few days.  Try pushing your double-spend attempt again in a couple of days.
