thanks so much mate for your fast help!
11c1242f793e5dddad25d6e44fa0dff73b8beec5525fe740d64b802f59cecb93 already got cofirmed!
i checked the second remaining transaction on VIABTC.COM some minutes ago and i dont get the "Transaction does not exist" error anymore - now clear to me because the previous unconfirmed TX got confirmed thanks to your help! i got an "Acceleration succeeded" status when submitting it to the last full hour at VIABTC.COM - nice...
Glad to be able to help.
just out of curiosity: how did you re-broadcast the transactions and if you used VIABTC.COM for re-broadcasting, which transactions (+ order) did you submit to resolve the previous unconfirmed transaction?! like i wrote: i got "Transaction does not exist" on every TX i tried...
thanks again and best greets,

I saw that the transaction should have been propagated through several blockexplorers and they aren't. Hence I took the raw transaction and submitted it to coinb.in/#broadcast to broadcast it again. By doing so, the transaction would be sent across the network and those without this transaction would put it in their mempool. The reason why ViaBTC said that the transaction didn't exist is because it wasn't well propagated. I broadcasted your first transaction (11c1242f793e5dddad25d6e44fa0dff73b8beec5525fe740d64b802f59cecb93) before your second (b178e3ece2bea76027a34a5e5249843bb40fa1bd0774aeec0a9bb45ab0edc88e) since the second transaction cannot confirm before your first. I would strongly advise you to use a desktop wallet like Electrum. Blockchain.info is too poorly designed.
You can get the raw transaction through a node or
https://blockchain.info/tx/[TXID HERE]?format=hex. Replace the TXID accordingly.
I'll just explain it based on my understanding if you didn't understand the quoted text very well.
You need to rebroadcast your transaction at
https://coinb.in/#broadcast to solve the "Transaction does not exist" problem.
Regarding the slow movement of you transaction, here's an accelerator:
https://www.viabtc.com/tools/txaccelerator/P.S. Rebroadcast you transaction first before accelerating it via VIABTC.com because if not the text, "Transaction does not exist", would show up. Also you need to wait for the accelerator hourly and need to do it quickly since it is limited or else you might miss the chance and try it again the next hour. Hope this helps you.
