My Bitcoin-Cash got stuck in an old address

[sir.humus]

I were using Schildbach Android bitcoin wallet. (which I still have access to from my phone)

When I claimed my BCH, i took the backup, extracted the mnemonic and sent the coins to appropriate wallet.
but through the process, a message appeared saying:

"1 non-deterministic keys found.
Your mnemonic backup does NOT back up your entire wallet."

and indeed, one of my addresses (which holds part of my coins) was not discovered, and now my BCH is stuck.

What can I do to gain access to this address?
Any help would be appreciated...

I am not sure I understand your question. Did you successfully claim your BCH? If the answer is yes, the just take the recovery phrase of your Schildbach  android wallet and recover your coins from any other wallet that supports Bitcoin cash. My personal preferred is Coinomi and the bitcoin.com wallets. I hope that helps. Can you post your public wallet address? Which wallet are you trying to recover from?

I claimed only part of my BCH,
The other part is in an old address.

As I understand it there is two types of addresses:
1st type non-deterministic
2nd type deterministic

All the BCH from deterministic addresses were claimed successfully,
but I still have one old non-deterministic address which I don't know how to work with.

Here it is:
17R3urY2wPb62DWagnrsioEiweNkYA8KYS

So, who can help me rescue those BCH?

Ooh I see. I was not aware of this problem, but it looks like you are not alone. Misery loves company. I found this post, someone says the mycelium wallet might help. Please go through the posts, you might find some idea.
